稻草覆盖量对红壤旱坡地花生生长环境及产量形成的影响
Effects of rice straw mulching amount on the growth environment and yield formation of peanut in dry sloping land of red soil
摘要
Abstract
According to the adverse effects of the characteristics of seasonal drought in Jiangxi Province on red soil sloping land,a study on the effects of different straw mulching amount(1 500,3 000,4 500,6000 kg·hm-2 and 7 500 kg· hm-2) on the growth and yield of peanut in red soil was carried out.The results showed that the daily variation of soil moisture,temperature and electrical conductivity of peanut field decreased with the increase of rice straw mulching amount,and the occurrence of weeds decreased correspondingly.But dry matter production,nodule weight,mature leaves residues and yield of peanut in a parabolic shape that first increased and then decreased with straw mulching quantity increased,and the straw coverage of 4 500 kg· hm-2 was the best performance.Considering the effect of straw mulching on controlling weeds,reducing drought and increasing crop yield,it was concluded that the amount of rice straw in red soil sloping field was about 4 500 kg· hm-2.关键词
