There was a significant positive correlation between grain number and weight，a significant negative correlation between grain number and 100-grain weight and mean grain perimeter，and a significant positive correlation between grain number and pollen polar axis length P and equatorial axis length E；Pollen polar axis length P and equatorial axis length E were negatively correlated with seed size and girth.【Conclusion】Higher grain weight and 100-grain weight could be obtained by selecting smaller pollen grains in seed melon breeding. In order to select a variety with a large number of seeds per melon，it is necessary to select a small seed material. The polar-axis length and equatorial circumference of polar-axis of polar-axis of pollen and the smaller polar-axis length of equatorial axis of polar-axis of pollen should be selected for breeding large-grain varieties. This finding from this study provides a scientific basis for breeding new varieties of seed melons.

Analysis of effects of water and nitrogen timing on cotton root morphological characteristics and yield formation LI Yujiang, LIN Tao, ZHANG Pengzhong, CUI Jianping, GUO Rensong, LI Qianwen, TANG Qiuxiang 2025, 62(8): 1892-1906.  DOI: 10.6048/j.issn.1001-4330.2025.08.008 Abstract ( )   PDF (4576KB) ( )   【Objective】Root is the main part of crops to absorb water and nutrients. Reasonable water and fertilizer management is crucial to the development and function of roots, and a key strategy to improve crop productivity and sustainability. This project aims to reveal the regulation mechanism of irrigation and nitrogen application timing on cotton root morphology and yield formation, optimize root health and crop growth soil environment.【Methods】The effects of different water and nitrogen timings on root morphology, root shoot ratio and yield formation of cotton were simulated by soil column under full irrigation（450 mm, no stress CK, W1） and deficit irrigation（225 mm, severe deficit, W2）. The different water and nitrogen timings were divided into three stages according to the equal time interval of each irrigation process, and the nitrogen application amount was added to a certain period or all periods. The treatment was（A: 100 % N was dripped in the later period; B: WN uniformly mixed drip; C:100 % N in the middle ; D : 100 % N in the anterior segment ）.【Results】 80.10%-91.58% of the root biomass was distributed in the 0-40 cm soil layer, which was the area where the root morphology of cotton was easily affected by the timing of nitrogen application. Under W1 treatment, compared with A（CK）treatment, B, C and D treatments significantly reduced root biomass by 5.10%, 3.96% and 9.98%, and mainly reduced root biomass in 0-20 cm. The advance of nitrogen application time increased deep root biomass. Among them, C treatment significantly increased root length and surface area in 0-40 cm soil layer, and significantly reduced root average diameter and root shoot ratio. Its yield, water use efficiency and nitrogen partial productivity increased by 8.22%, 7.31% and 5.86 %, respectively. Under W2 treatment, compared with A（CK）treatment, the root biomass of B, C and D treatments increased significantly by 19.80%,5.19% and 10.13 %, respectively, and the root-shoot ratio decreased significantly in advance of nitrogen application time, but the seed cotton yield, water use efficiency and nitrogen partial factor productivity did not increase significantly.【Conclusion】Water and nitrogen timing has a certain effect on root morphology, root-shoot ratio, yield, water and nitrogen use efficiency. When the irrigation water is sufficient, the middle nitrogen application can be used, which is beneficial to optimize the root distribution in the 0-40 cm soil layer, increase the root length and surface area, strengthen the root absorption of water and nitrogen in the deep soil layer, reduce the root-shoot ratio, and improve the water use efficiency, nitrogen partial productivity and yield. When irrigation water is scarce, water and fertilizer should be mixed and dripped, which is conducive to the uniform distribution of nitrogen fertilizer in the soil layer, promoting root absorption, easily forming a strong root system, and improving the resistance of cotton.

Effects of reduced nitrogen fertilizer combined with humic acid on nutrient absorption and yield of cotton CHEN Guoyue, ZHANG Kai, GUO Xiaomeng, GUO Jingyu, ZHAO Tongzhou, CHENG Baitao, ZHANG Lingjian 2025, 62(8): 1916-1924.  DOI: 10.6048/j.issn.1001-4330.2025.08.010 Abstract ( )   PDF (5545KB) ( )   【Objective】To study the effects of nitrogen fertilizer reduction combined with humic acid on plant biomass, seed cotton yield, nutrient absorption and nitrogen fertilizer utilization rate in cotton field under drip irrigation under film in the hope of providing technical support for nitrogen fertilizer reduction and efficiency increase in Xinjiang cotton field.【Methods】In 2022, a field experiment was carried out in Jinghe County, Xinjiang. Five treatments were set up: no nitrogen fertilizer control（CK）, farmers' nitrogen application rate （N130% ）, soil testing recommended nitrogen application rate （N100% ）, nitrogen fertilizer reduction （N70%）, nitrogen fertilizer reduction combined with humic acid（N70%+HA）. Plant samples were collected during the boll opening period. The biomass, nutrient content and seed cotton yield of each organ of cotton were measured, and the nitrogen fertilizer utilizer rate of cotton field was calculated.【Results】Compared with the recommended nitrogen application rate of soil testing formula, the reduction of nitrogen fertilizer significantly reduced the total biomass of cotton, the cumulative absorption of nitrogen, phosphorus and potassium and the yield of seed cotton. Compared with the nitrogen fertilizer reduction treatment, the addition of humic acid （N70% + HA）significantly increased the cumulative absorption of nitrogen, phosphorus and potassium and seed cotton yield of cotton, reaching the same level as the recommended nitrogen application rate of soil testing and formula fertilization. The apparent utilization rate of nitrogen fertilizer reached the highest in（N70%+HA） treatment, which was 48.76%, and which was significantly higher than that of farmers' nitrogen application treatment.【Conclusion】In summary, the application of humic acid under the condition of nitrogen fertilizer reduction can promote the nitrogen absorption of cotton, increase the yield of seed cotton and improve the utilization efficiency of nitrogen fertilizer, which can be used as an effective measure for chemical nitrogen fertilizer reduction and sustainable nitrogen management in cotton fields in Xinjiang.

Study on adaptability of cotton canopy temperature monitoring by UAV infrared thermal imaging technology：analysis of different water and nitrogen conditions JIA Tao, TANG Qiuxiang, CUI Jianping, ZHANG Pengzhong, WANG Liang, SHAO Yajie, FANG Wancheng, BAO Longlong, LIN Tao 2025, 62(8): 2044-2054.  DOI: 10.6048/j.issn.1001-4330.2025.08.022 Abstract ( )   PDF (2116KB) ( )   【Objective】Drought is an important factor affecting crop yield and water and nutrient status affect the grade and frequency of drought stress. These complex processes are manifested on a macro scale through the canopy temperature（Tc）of crops. In order to explore the applicability of unmanned aerial vehicle （UAV）infrared thermal imaging technology for monitoring Tc during the formation of complex canopy of densely planted cotton，in this project，a UAV platform equipped with a thermal infrared remote（TIR）sensor is used to study the changes of cotton Tc under different water and nitrogen environments.【Methods】We set irrigation quota（3 150，4 050 and 4 950 m3/hm2）and nitrogen application rate（0，300 and 600 kg/hm2）in Aksu cotton district，Xinjiang，China，The effects of main moisture control measures on the temporal and spatial distribution of cotton Tc were analyzed by converting radiation brightness temperature into actual temperature measurement，the difference of Tc in different treatments cotton，and the change of Tc in different growth periods by the same treatment.【Results】Different irrigation rates and nitrogen application rates could affect cotton Tc. In all 9 treatments，the highest Tc difference reached 6.2 ℃ and the lowest Tc difference reached 1.9 ℃. From 3 150 m3/hm2 to 4 050 m3/hm2，Tc decreased significantly. From 4 050 m3/hm2 to 4 950 m3/hm2，under normal irrigation conditions，Tc under the 0 kg /hm2 nitrogen treatment was 1.8 ℃ higher than that under the 300 kg /hm2 nitrogen treatment，and 2 ℃ higher than that under the 600 kg /hm2 nitrogen treatment. Under the condition of 4 950 m3/hm2 irrigention treatment，the Tc of the 0 kg /hm2 nitrogentreatment was 1.5 ℃ higher than that of the 300 kg /hm2 nitrogen treatment，and 1.7 ℃ higher than that of the 600 kg /hm2 nitrogen treatment. Under the condition of normal irrigation，the Tc of the 0 kg /hm2 nitrogen treatment was 1.8 ℃ higher than that of the 300 kg /hm2 nitrogen treatment，and 2 ℃ higher than that of the 600 kg /hm2 nitrogen treatment. Under the condition of 4 950 m3/hm2 irrigention treatment，the Tc of the 0 kg /hm2 nitrogen treatment was 1.5 °C higher than that of the 300 kg /hm2 nitrogen treatment and 1.7 °C higher than that of the 600 kg /hm2 nitrogen treatment.【Conclusion】Tc is significantly affected by irrigation amount. Increasing irrigation amount can effectively reduce Tc，but increasing irrigation amount after reaching a certain degree will lead to Tc increase. Nitrogen application rate can slightly affect Tc，and within a certain range，the higher the nitrogen application rate，the lower the Tc. The use of drones to monitor cotton Tc under different water and nitrogen conditions shows a good difference between treatments，which can be used as a rapid and non-destructive diagnostic technique to evaluate cotton water and fertilizer nutrition to guide cotton precision irrigation and fertilization.

It is necessary to research the overall status and variation trends of the machine-harvested cotton quality in Xinjiang, explore technical approaches to improve its quality, and thereby provide theoretical and technical support for the high-quality development of Xinjiang cotton.【Methods】Guided by the notarized inspection data of raw cotton quality in Xinjiang over past years, this study analyzes the trends in quality grading of raw cotton during the mechanized harvesting transition, focusing on the Xinjiang divisions in both North and South Xinjiang Production and Construction Corps（XPCC）, Xinjiang Uygur Autonomous Regin（XUAR）, and the entire Xinjiang. 【Results】The widespread adoption of machine-harvested cotton has significantly impacted the percentage of high-quality raw cotton（≥29.0 mm, ≥29.0 cN/tex, micronaire value 3.7-4.2）, showing a trend of initial decline followed by an increase. When the proportion of machine-harvested cotton in the XPCC and XUAR was below 60% and 20%, respectively, the harvesting technology was not yet mature, leading to a decline in the percentage of high-quality raw cotton by 25.7%-49.3%. However, when the proportion exceeded 60% in the XPCC and 20% in XUAR, the percentage of high-quality raw cotton stabilized. During the promotion of machine-harvested cotton, the fiber length and breaking strength of raw cotton in Northern Xinjiang were significantly higher than those in Southern Xinjiang by 0.1-1.0 mm and 0.8-1.8 cN/tex, respectively.【Conclusion】 The quality grades of raw cotton, particularly the proportion of high-quality raw cotton, have affected by the popularization and application of machine-harvested cotton in Xinjiang to a certain extent. Importantly, as the technology matured, the share of all quality grades of Xinjiang raw cotton tend to stabilize.

Under the background of "double cycle"，China's grain market should base itself on the domestic grain cycle. The immutable factor farmland water conservancy is the new growth point of domestic grain output and the key to the double circulation of Chinese grain market. The aim of this is to explore the impact of irrigation and water conservancy on China's grain market.【Methods】The effective irrigation ratio of cultivated land was taken as the evaluation index. The partial equilibrium model and ARIMA model were established to analyze the impact of farmland water conservancy construction on China's grain market.【Results】The results showed that the effective irrigation ratio of cultivated land increased domestic grain output by 1%，and domestic grain output significantly increased by 618.93 tons，accounting for 1% of the whole domestic grain yield. If the effective irrigation ratio of cultivated land in China increases by 1% year by year，the domestic grain output would reach 838 million tons by 2030，and China will be self-sufficient in the grain market. Farmland irrigation and water conservancy reduced the prices of domestic and imported grain，increased the proportion of farmland under effective irrigation by 1 percent，cut down the price of domestic grain by 2.18 percent and the price of imported grain by 3.37 percent.【Conclusion】Farmland water conservancy helps to promote the stable development of China's grain market. Strengthening the construction and maintenance of farmland water conservancy，increasing the research and development and promotion of farmland water conservancy irrigation technology and scientific utilization of domestic and international resources are the keys to the stable development of China's grain market under the new background.
