地膜覆盖在农业生产中已得到了很广泛的应用,对提高花生、马铃薯、蔬菜等作物的生物产量起了很大作用.甘薯秋种往往因气温低等不利因素而影响其产量,为了探讨旱地三熟制中,玉米甘薯连作的效果,寻求秋甘薯高产的途径,我们通过两年的覆膜试验,明确了地膜覆盖的环境效应及其对秋甘薯生长发育的影响,为推广秋甘薯地膜覆盖应用提供依据.
Plastic film mulching has been widely used in agricultural production and played a significant role in improving the biological yield of crops such as peanut, potato, vegetable, etc. Autumn sweet potato often affects its yield due to unfavorable factors such as low temperature, Three-cropping, corn and sweet potato continuous cropping effect, seeking autumn sweet potato high yield way, we passed two years of film test, clear environmental effects of mulching and its impact on autumn sweet potato growth and development, in order to promote autumn sweet potato mulching Application basis.
