Effects of Film Mulching on Soil Temperature and Yield of Peanut by Ridge Planting in Summer
摘要
Abstract
In order to investigate the effects of film mulching on the soil temperature of ridge planted summer peanut,and its effects on peanut growth,development and yield,with unmulched ridge as control,the dynamic changes of soil temperature under white film and degradable black film treatments were analyzed,also,the effects on the peanut main economic characteristics and pod yield were investigated,the relationship between soil temperature effect and air temperature was discussed.The results showed:The daily minimum and average temperatures of 10 cm below soil surface were increased and the daily maximum temperature of 10 cm below soil surface was decreased under white film treatment.The daily minimum temperature of 10 cm below soil surface was decreased,and the daily maximum and average temperatures of 10 cm below soil surface were increased under degradable black film treatment.The average daily minimum temperature of 10 cm below soil surface under white film was 1.8-3.2℃ higher than that of soil surface,and was 0.7-2.0℃ lower than that of soil surface under degradable black film treatment.The average daily maximum temperature of 10 cm below soil surface was 1.6-6.0℃ lower than that of soil surface under white film,and was 3.1-6.3℃ higher than that of soil surface under degradable black film treatment.The average value of daily average tempera-tures of soil surface and 10 cm below surface increased with the raise of air temperature,different air temperature range had different effects on the average value of daily average temperature of soil sur-face and 10 cm below soil surface,there was also different effects between white film and degradable black film treatments.The warming effect of film mulching promoted the growth and development of the peanut,on the whole,it was beneficial to increase the leaf area and dry mass per plant,but there was presenility in the late growth period.There were no significant effects on the peanut main eco-nomic characteristics under film mulching.The pod yields of white film,degradable black film and unmulched ridge treatments were 4,286,4,247,and 4,028 kg/ha,respectively.In addition,mulching film also had certain effect on the number of peanut nodules.This study offered guiding significance for the high yield cultivation and film mulching technology of ridge planted summer peanut.关键词
