果树秋比春覆地膜好一般果树地膜覆盖多在早春进行，但易造成夏季地温过高不利果树生长，到秋季地膜毁坏，起不到覆盖作用。山东农业大学园艺系杨洪强等经过覆膜最佳时期对比试验。认为秋季果树覆膜效果最好：秋季土壤水分充足，覆膜有足墒可保，可减轻晚秋和冬春干旱，可...
Fruit tree autumn than the spring cover film Good general Mulberry fruit tree mulching and more in early spring, but easy to cause adverse summer fruit and vegetable growth, to the fall of the film damage, can not cover. Shandong Agricultural University horticultural Yang Hongqiang, etc. After the best film during the comparative test. That the best effect of autumn fruit tree laminating: adequate soil moisture in autumn, covered with enough moisture to protect, can reduce late autumn and winter drought, can be ...
