露田马铃薯可以通过中耕除草,控制杂草危害,春马铃薯地膜促成栽培省去了中耕除草环节,杂草就容易滋生,严重时杂草顶起地膜影响地膜的增温效果,同时与马铃薯争夺养分,影响早熟高产。因此化学除草是春马铃薯地膜促成栽培一项配套技术,根据我地冬春季杂草以看麦娘和繁缕为主的实际,在上一年选用乙草胺大区对比试验基础上,1996年在春马铃薯地膜促成栽培上进行乙草胺用量试验,将有关情况整理如下。
Tinting potatoes can be weeds through weed control to control weeds, spring potato film to facilitate the cultivation of cultivated herbicides eliminating the need for weeds is easy to breed, in serious weeds top film mulching affect the warming effect of the film, while competing with the potato nutrients , Affecting early maturity and high yield. Therefore, the chemical weeding is a spring potato film to promote cultivation of ancillary technology, according to my winter and spring weeds to see the mother and the prevalence of the main strands of sophistication, acetochlor selection in the previous year on the basis of a large area comparison, 1996 In spring potato film to promote the cultivation of acetochlor dosage test, the situation is sorted as follows.
