Technical advice on chemical weeding in rapeseed field

Rape fields and rapeseed field are important factors influencing the high yield and stable yield of rapeseed. Therefore, we must grasp the chemical weeding in rapeseed field to improve the yield. In view of the characteristics of grassland in rapeseed field in our district, the following suggestions on chemical weeding techniques are proposed:
First, weeding sowing before transplanting. Rape before sowing and transplanting, per acre with 20% paraquat 150-200 ml or 20% gram trace 100-150 ml or 10% glyphosate 500 ml, water evenly sprayed 35 kg to eliminate the old grass.
Second, before the bud blocking. Mu with 35% a wettable powder 60 g water 35-50 kg spray, soil treatment, blocking weeds. Live rape can be applied within 1-2 days after sowing of soil, and rapeseed should be used for 1-3 days before transplanting.
Third, stem and leaf processing. Weeds dominated by grasses, in the 2-4 leaf stage of weeds, can use 5% quizaloprene EC 45-60 ml per mu, or 5% high efficiency canola EC 40-60 ml; The broad-leaved grass-based plots are used in the weeds of 2-4 leaf-zones with 30% of good and good emulsifiable concentrate 50 ml; single and dicotyledonous weeds are mixed in plots, which can be used in weeds for 2-4 leaf-leaf periods. 17.5% block knife EC 100-140 ml control. The above agents are all watered 35-50 kg spray.
Fourth, pay attention to matters. First, the amount of drug to be accurate, evenly diluted, not heavy spray; the second is the pre-embryo treatment, should be sprayed after sowing the cover to avoid direct contact with the seed and the drug; the third is in the treatment of stems and leaves, select the right weeding The agent is administered at high temperatures at noon to prevent phytotoxicity due to low temperatures.
