摘要/Abstract

摘要： 【目的】研究有机无机复混液态肥对棉花农艺性状、产量及土壤养分的影响。【方法】于新疆农业科学院安宁渠试验场、奎屯130团、精河县开展田间小区试验。试验设置3个处理,分别为 CK(不施肥)、CF(当地习惯施肥300 kg N/hm²(中高产),普通复合肥)、T(1 500 kg N/hm²,有机无机复混肥),每个处理重复3次。【结果】在棉花农艺性状、产量方面:新疆农业科学院安宁渠试验场、奎屯130团和精河县3个试验区,有机无机复混液体肥(T处理)均可获得与当地习惯施肥(CF处理)相持平的产量。T处理和CF处理间的棉花株高、干物质积累量及产量差异均不显著(P>0.05)。较CK、CF和T处理单株铃数、铃重和籽棉产量均显著提高(P ＜0.05),而衣分和马克隆值差异不显著(P>0.05)。在土壤养分方面:随着棉花生育期的推进,T处理和CK处理土壤有机质含量均呈不同程度降低趋势,而T处理土壤有机质含量保持稳定或略呈升高趋势。【结论】在棉花整个生育期中,有机无机复混液体肥可以替代常规化肥,且养分满足棉花整个生育期的生长需要。

Abstract: 【Objective】 To investigate the effects of organic-inorganic compound liquid fertilizer on cotton agronomic traits, yield and soil nutrients.【Methods】 Field trials were conducted in the Anningqu Experimental Field of Xinjiang Academy of Agricultural Sciences , Kuitun 130th Regimental Farm and Jinghe County .【Results】 In terms of cotton agronomic traits and yield, KT130 and JHC three experimental areas, organic-inorganic compound liquid fertilizer (T treatment) could obtain the same yield as the local conventional fertilizer (CF treatment). There were no significant differences in cotton plant height, dry matter accumulation, and yield between T and CF treatments (P> 0.05). Compared with CK, the boll number, boll weight and seed cotton yield of CF and T treatments increased significantly (P <0.05), while the differences in clothing fraction and micronaire value were not significant (P> 0.05). In terms of soil nutrients: with the advancement of cotton growth period, the soil organic matter content of T treatment and CK treatment showed a decreasing trend to different degrees, while the soil organic matter content of T treatment remained stable or showed a slight increase trend.【Conclusion】 During the entire growth period of cotton, organic-inorganic compound liquid fertilizer can replace conventional chemical fertilizers, and nutrients can meet the growth needs of cotton.
