Abstract:

【Objective】To study the effects of different mulching patterns and supplementary irrigation on soil water content, dry matter accumulation rate, photosynthesis and quality of peanut.【Methods】Jihua 18 (semi-prostrate-type ) and Huayu 9610 (erect type) peanuts were taken as test materials to set limited irrigation without film(T1), medium irrigation without film(T2), full irrigation without film(T3), full irrigation with film(T4), then tp analyze the photosynthetic characteristics and quality differences of peanuts under different treatments, and finally formulate a suitable combination model.【Results】The soil water content of peanut in T4 treatment was the highest.The soil water content of Huayu 9610 in T4 treatment was 3.26% higher than that in T1 treatment at the early growth stage, and that of Jihua 18 T4 was 3.63% higher than that in T1 treatment; under the same treatment, the soil water content of Jihua 18 was higher than that of Huayu 9610.The dry matter growth rate of peanut under T4 treatment was significantly higher than that of other treatments.Compared with T1-T3 treatment, the underground growth rate of Huayu 9610 increased by 0.6%, 0.5%, 0.3%, and the aboveground growth rate increased by 34.4%, 17.9%, 4.2% respectively at maturity; The underground growth rate of Jihua 18 increased by 1.2%, 0.8% and 0.2%, and the aboveground growth rate increased by 54.9%, 37.2% and 27.3%, respectively.The protein, oil content and oleic acid content of Jihua 18 were higher than those of Huayu 9610 under the same treatment; All kinds of indexes of Huayu 9610 increased with the increase of water content under no film treatment.【Conclusion】T4 treatment is beneficial to increase soil water content, dry matter accumulation, photosynthetic rate and quality of peanut.However, under the condition of film free cultivation, Jihua 18 (semi-prostrate-type) can increase the surface coverage area, reduce water evaporation, and maintain a higher soil moisture content and dry matter accumulation rate compared with Huayu 9610 (erect type).The comprehensive property index is better than that of upright peanut.

摘要:

【目的】研究不同覆盖模式与补充灌溉对花生干物质积累速率、光合特性及品质的影响。【方法】以花生品种冀花18(半匍匐型)和花育9610(直立型)为供试材料,设置无膜限制灌水(T1)、无膜中等灌水(T2)、无膜充分灌水(T3)和有膜充分灌水(T4)4个处理,分析不同处理下花生光合特性及品质的差异,制定适宜的组合模式。【结果】花育9610生育前期的土壤含水率T4较T1处理高3.26%,冀花18 T4较T1处理高3.63%;相同处理下,冀花18土壤含水量高于花育9610。T4处理下花生干物质积累速率显著高于其他处理,与T1~T3处理相比,成熟期花育9610干物质积累速率地下部分别提高了0.6%、0.5%和0.3%,地上部分别提高了34.4%、17.9%和4.2%;冀花18干物质积累速率地下部分别提高了1.2%、0.8%和0.2%,地上部分别提高54.9%、37.2%和27.3%。相同处理下冀花18的蛋白质含量、含油量、油酸含量均高于花育9610;无膜处理下花育9610各类指标随着水分的增加而提高。【结论】T4处理下花生各指标最佳。冀花18作为半匍匐型花生,能够增加地表覆盖面积,减少水分的蒸发,有利于提高土壤含水量,增加植株干物质积累,提高花生光合速率及品质。半匍匐型花生在无膜栽培模式下综合性状指标相对较优。
