No-tillage direct-seeded rapeseed field (rice blast, drought and flood) weeds are characterized by early emergence and large amount of production. The rapeseed seedlings and weeds in the field grow in almost the same time, and they compete with the oilseed rape to compete for water and compete for nutrients. Rape seedlings grow normally. No-tillage rapeseed field chemical control measures should be taken before and after the compensation strategy, focusing on the rapeseed before sowing, seedling before sowing, "kill one" and seedling control. A kill before sowing: that is, 5-7 days before the rapeseed, killing with a phytotoxic herbicide. Use 10% glyphosate water per acre 500 to 750 ml, or 41% Dalinon, 41% glyphosate up to 200 to 250 ml, or 20% paraquat water 100 to 150 ml, or 95% power Deep (40g + 5ml auxiliary agent) add water to 40-50kg uniform spray to kill the weeds that have grown out of the ground. After sowing: After sowing seeds, flatten the surface, in the case of keeping the field moist, use 50% Guangjia'an (acetochlor + clomazone) 100ml, or 99.9% flying cow (B) 40-60 grams of water, 40-50 kilograms of uniform spray, soil closure treatment. Seedling control does not timely eliminate or eliminate the poorly-effective fields before seedling emergence, and the corresponding chemical herbicides can be used to treat the stems and leaves before the wintering of rapeseed and rape in the spring. Weeds dominated by grass weeds can be used in the grassy weeds 3 to 5 leaf-leaf times per acre with 40 kg of this autumn (crissone) (more than 5 leaves, or serious, resistant weeds Where appropriate to increase the amount of drug), or 12% steadily tillage or collecting music 45-60 ml, or 10.8% Tianshui 40-60 ml, or 10.8% quizalofop; 40 ml; dominated by broad-leaved weeds The plots can be used in rapeseeds before the winter before the peak of weeds or broad-leaved weeds 2 to 3 leaf stage dragon 8 to 10 grams per mu, or 50% grass removal Ling 30 ml, etc., add 30 kg of water evenly spray. 1 Inactivated herbicides lose their activity in the presence of soil and should be used only when weeds are present in the fields before sowing. Do not use them in the absence of weeds in the field, otherwise no weeding effect will result in waste. 2 If acetochlor is used improperly, it will cause phytotoxicity to rape, especially after the spraying, it will affect the emergence of seedlings before the emergence of rapeseed. The dry soil will affect the control effect. Pay attention to the use of appropriate drugs, do not arbitrarily increase the dosage; appropriate increase in water consumption when the soil is dry. More than 3 kinds of herbicides, especially those that prevent broad-leaved weeds, should not be used after convulsions in rapeseed, otherwise they are prone to produce phytotoxicity. Live rapeseed fields should be based on pre-winter herbicides and spring herbicides should be selected as soon as possible. . 3L-size Carrot,3L-size Red Color Carrot,Big Size Carrot,3L-size Premium Carrots Yirun Agricultural Cooperative , https://www.yiruncn.com
