According to local conditions, the selection of drugs is accurate. Herbicides should be pre-emergence herbicides. Guangmiaoling has a short residual period and is safe for diarrhea. It is the preferred agent. Soybeans before weeding, chemical weeding before seedlings are not available for K.K.L., G.L.G., 2,4-D.
Strict standards, scientific mixing liquid. After sowing soybeans, the formula for chemical weeding before seedlings is: 48% clomazone EC 70 ml + 59% acetochlor EC 100 ml + 70% Mastolactone Soluble powder 2 g, 30 kg water, can be sprayed to an acre of land . When preparing compounded pesticides, the pesticides shall be added to the apparatus according to the standard. The powdered pesticides shall be diluted with a little clear water to be added into the apparatus after the mother liquor is added. Finally, the quantitative water shall be added. The instrument must not be filled with water before adding the chemicals to prevent water from being produced. Drugs are not fully dissolved and sprayed unevenly and have poor efficacy.
Spray at the right time to ensure sufficient water. Soybeans should not be sprayed immediately after sowing, to prevent drought and other weather effects on efficacy, but it should not be too late. The correct method is: the lyrical plots are sprayed 3-4 days after sowing and the plots with poor lye are sprayed 4-5 days before emergence. Therefore, when applying pre-emergence weed control technology, we must pay attention to sufficient water. For example, the air-injected sprayer for agricultural small four-wheel tractors weighs 175-200 kilograms, is equipped with high-pressure nozzles, and the throttle speed is in the second gear of the forward speed, so that each can of liquid can be sprayed with 6-7 mu to ensure the use of mu. The amount of water is 30-35 kg. At the same time depending on soil moisture and climatic conditions, it can be sprayed at any time with clear water, 20-30 kg per mu, in order to improve efficacy.
(1) Natural astaxanthin: it is a powerful antioxidant, known as the king of anti-aging. Its ability to scavenge free radicals is 6000 times that of vitamin C; 1000 times that of vitamin E; yes β- 100 times the efficacy of carotene; It is 20 times more effective than selenium; It is 700 times the efficacy of anthocyanins; It is 320 times the efficacy of tea polyphenols; It is 10 times more effective than lycopene; 800 times that of coenzyme Q10;: It is 240 times more effective than grape seed extract; It is 200 times the efficacy of carotol (Lutein); It is 3000 times higher than resveratrol[ 1]
(2) Vitamin C: also known as ascorbic acid, is an acidic polyhydroxy compound containing 6 carbon atoms: lack of vitamin C can greatly reduce endurance exercise ability. Vitamin C supplementation can significantly reduce exercise-induced oxidative stress. The safe dose of vitamin C supplementation is 0.5 ~ 3.0 g / day. The recommended daily dose of vitamin C supplement is 0.5 ~ 2.0 G.
(6) Anthocyanins: anthocyanins belong to biological flavonoids, and the most important physiological active functions of flavonoids are free radical scavenging ability and antioxidant ability.
(7) Tea polyphenols: tea polyphenols are all natural antioxidant foods extracted from tea. They have the characteristics of strong antioxidant capacity, non-toxic side effects and no peculiar smell. The antioxidant effect of tea polyphenols can eliminate reactive oxygen species and inhibit the consumption of vitamin C, so it can keep skin delicate and white.
