First, sowing control technology points
1. For the plots dominated by grasses and weeds, within 3 days after sowing, 50% acetochlor EC 100 to 150 ml, or 33% penicillin EC 150 to 200 ml before soybean emergence , spray 50 to 80 kg of water on the soil surface. Under drought conditions, increase water use or lightly mix 2 cm.
2. The plots mainly consist of broad-leaved weeds such as purslane and shovel, after seeding, 50% acetochlor EC 100 ml + 24% oxyfluorfen (diphenyl ether herbicide) ) Emulsion 10 to 15 milliliters of sprayed soil surface, soil organic matter content is low, sandy soil, low-lying land, water, foot with low dose, and vice versa with high doses. At the same time to remind everyone of the understanding of the problem of harm, the soybean seedlings encounter low temperature, high humidity, field long-term accumulation of water or drug is too large, vulnerable to injury, the symptoms are leaf shrinkage, but the soybean grows 3 leaves, temperature After the increase, normal growth can be restored, and generally it does not affect the yield.
Second, the growth of control technology points
1. Weeds dominated by grass weeds, when the weed seedling stage with 5% fine quizalophor Emulsion 50 ~ 70 ml, or 10.8% high efficacy fluphanopyrolidine EC 20 ~ 40 ml, water 30 Kilogram spraying.
2. With broad-leaved weeds as the main plot, when the weeds are basically in the seedling stage, the mu will be sprayed with 10% ethylcarbaflorin EC 10 to 30 ml and 30 kg water.
3. The plots of grasses and broad-leaved weeds are mixed, and when the weeds are basically in the seedling stage, 7.5% of the mu is used in the mu (802.4 ml of carbazine is registered by the Ministry of Agriculture). Or use 5% quizalofop-pigment EC 50-75 ml + 25% acifluorfen (diphenyl ether herbicide) water 50 ml, spraying 30 kg of water.
In the above three cases, the specific dosage should be determined according to the grass condition and the public opinion, and the high dosage should be used when the grass is large and the sensation is poor. It is reminded that diphenyl ethers should be applied to soybeans when they have 2 to 4 compound leaves, and it is easy to produce phytotoxicity if they are applied too early or too late.
Royal Jelly is also called Bee Milk. The fresh royal jelly is slightly ropy milk paste substance; it is the excretive mixture of nutrition gland and maxilla gland of the head of little worker bee. The worker bees use this to feed the 1-3 days` worker bee larva and drone larva, 1-5.5 days` queen bee larva and queen bee in the oviposition period. The royal jelly is the biologic product containing very complicated active elements which contains almost all the nutrition elements required by the growth of the human body.
