Abstract：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.
