摘要
以山花108为试材,在大田条件下设置麦田套种、直播露地和直播覆膜三种种植方式,系统研究了不同种植方式对麦油两熟制花生生理特性及品质的影响。结果表明:在花生生育前期,夏直播覆膜处理可提高其叶面积系数,增加功能叶的叶绿素含量、气孔导度、蒸腾速率,提高叶片净光合速率,增加植株干物质积累量,促进营养生长。麦套花生能显著提高花生生育中后期叶面积系数和叶绿素含量,改善光合性能,增加干物质积累,提高单株结果数、出仁率和果重。三种种植方式下花生产量表现为麦套>直播覆膜>直播露地。发展麦油两熟制花生,在人力和物力充足条件下,宜选用麦田套种方式;为适应机械化,宜采用夏直播覆膜栽培,同时力争早播和适当增加密度,保证产量。
Taking Shanhua 108 as material,we compared the physiological characteristics and quality of peanut in three different cropping patterns （wheat field inter-cropping,summer direct seeding treatment and summer direct seeding with plastic film treatment ）under field conditions.The main results were as follows.In the earlier growing period of peanut,the summer direct seeding with plastic film treatment could increase the leaf area index,chlorophyll content in functional leaves,stomatal conductance,transpiration rate and net photo-synthetic rate,thus promoted the amount of dry matter accumulation and vegetative growth of peanut.Wheat field inter-cropping could significantly increase the leaf area index and chlorophyll content in the middle and late growth period of peanut,improve photosynthetic performance and dry matter accumulation,thereby boost the fruit number per plant,kernel rate and fruit weight.The peanut yield under three cultivation patterns showed as wheat field inter-cropping 〉summer direct seeding with filming〉summer direct seeding.There-fore,with sufficient manpower and material resources,wheat field inter-cropping pattern should be adopted for wheat-peanut double cropping system;to adapt to mechanization,summer direct seeding with filming pattern was suitable,and early sowing and appropriately increasing density should be adopted to ensure yield.
