移栽油菜化学除草是高产栽培的一项重要措施,其除草效果一般都在90%以上,比人工除草效果要提高20%以上,且因除草不像人工除草那样要松动土壤,油菜根茎牢固,倒伏率要比人工除草下降30%左右。因此深受农民欢迎,现将移栽油菜田化除技术介绍如下:移栽油菜田杂草发生规律。稻茬移栽油菜主要杂草有繁缕、看麦娘、日本看麦娘、雀舌草、碎米荠、硬草、泥胡菜、
Transplanting rapeseed chemical weeding is an important measure of high-yielding cultivation, and its weeding effect is generally above 90%, which is more than 20% more than that of artificial weeding. Because weeding does not loosen soil like weeding, The lodging rate is about 30% lower than that of artificial weeding. So deeply welcomed by farmers, now transplanting rape fields in addition to the technology described below: Weed transplanting rape field law. Stubble transplanted rape of the main weeds have sophistication, to see Amanita, Japan to see Amanita, spat, Chestnut, hard grass, mud vegetables,
