随着种田大户的不断增多,机插稻面积逐年增加,它在杂草防除的技术要求上,有别于常规早稻栽培,而且机插稻基本上都是采用除草剂除草。现将机插早稻田化学除草技术介绍如下,供参考。机插早稻秧田除草。用机插稻栽插,秧田一般处于4叶期,比人工手插的秧苗小。秧苗小,一方面稻秧对除草剂的抵抗力相对较弱,另一方面秧苗心叶容易被水淹没,使用除草剂不当很容易造成药害。秧田一般采用双膜湿润育秧、塑盘育秧等方式育秧,杂草主要以
With the increasing number of farming households, the area of machine-inserted rice is increasing year by year. It is different from the conventional cultivation of early rice in the technical requirements of weed control. In addition, the machine-inserted rice basically uses herbicides to weed out grass. Now insert machine Waseda chemical weeding technology introduced below for reference. Machine inserted early rice seedling weeding. Planting rice planting, seedling field generally in the 4 leaf stage, than the artificial hand inserted seedlings. Small seedlings, on the one hand, rice seedlings of herbicides resistance is relatively weak, on the other hand the seedling heart leaves easily flooded, the use of improper herbicide can easily lead to injury. Seedling generally use double-membrane wet seedling, plastic tray Yang seedling and other ways to seedlings, weeds mainly
