Foliar spraying fertilizer. After harvesting, the resistance of grape leaves was strong, and the concentration of foliar fertilizers could be appropriately increased. Foliar spraying was performed with 0.5% urea and 0.5% potassium dihydrogen phosphate. Fertilize early. Immediately after fruit picking, immediately apply one-time quick-acting chemical fertilizer, and then apply topdressing to the late-maturing varieties before fruit harvesting, applying potassium sulphate ternary compound fertilizer or fruit tree-specific fertilizer 20 kilograms per mu. Apply base fertilizer. The effect of basal fertilization after harvesting from the deciduous grape is good. Using the root system to recharge in an active period can not only restore the damaged roots, but also play a positive role in the accumulation of nutrients in the tree. Apply 3,000 kg of high-quality mixed fertilizer per acre, 15 kg of pure nitrogen, 15 kg of pure phosphorus, 25 kg of pure potassium, 25 kg of biological calcium fertilizer, 2 kg of zinc sulfate, 2 kg of ferrous sulfate, 0.5 kg of borax, 60% nitrogen removal 50% of potassium is left as topdressing, and the rest of the fertilizer is applied in a fertilization ditch with a depth of 30 cm and a width of 40 cm. Whether it is to apply fast-acting fertilizers or base fertilizers in autumn, it must be watered in time to sink the soil, promote the rapid decomposition of fertilizers, restore tree vigor, and accumulate nutrients to provide adequate nutrition for the growth, flowering, and fruiting of the second year.
Feed additive refers to a small amount or trace substance added in the process of feed production, processing and use. It is used in feed in small amount but plays a significant role. Feed additive is an inevitable raw material in modern feed industry. It has obvious effects on strengthening the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed cost and improving the quality of animal products.
Classification
1. Bile acid
2. Acidifier
5. Promote growth Vitamin A Powder, Lactose Powder, Oxytetracycline Dihydrate Powder, Vitamin D3 Powder Xi'an Tian Guangyuan Biotech Co., Ltd. , https://www.tgybiotech.com
It can promote fat digestion and absorption, protect liver and gallbladder, improve livestock and poultry health and improve feed utilization.
Including citric acid, fumaric acid, lactic acid, acetic acid, hydrochloric acid, phosphoric acid and compound acidifier. Adding an appropriate amount of acidification Qi to the pig diet can significantly improve the daily gain of pigs and reduce the feeding cost.
Including olaquindox, pig fast growth, fast fertility, blood polypeptide, liver residue, animal music, fat pig Wang, etc.
6. Trace elements
Including copper, iron, zinc, cobalt, manganese, iodine, selenium, calcium and phosphorus, which can regulate body metabolism, promote growth and development, enhance disease resistance and improve feed utilization. The daily gain of postnatal pigs can generally be increased by 10% - 20% and the feed cost can be reduced by 8% - 10%,
7. Vitamins
It includes vitamins A, D2, e, K3, B1, D3, B2, B6 and C, as well as a variety of vitamins, choline, pig premix additives, vitafat, Ted vita-80, French fat, health care element, strong element, etc. it can be scientifically selected and used according to different pig varieties and different growth and development stages.
8. Amino acids
It includes 18 kinds of amino acids such as lysine, methionine and glutamic acid, as well as Shengbao, livestock treasure, feed yeast, feather powder, earthworm powder, feeding music, etc. the most used additives are lysine and methionine. Adding 0.2% lysine to the diet can increase the daily gain of pigs by about 10%.
9. Antibiotics
Gold toxin, salinomycin, tetracycline, Bacillin, lincomycin, Kangtai feed additive, zhubao, Baosheng, etc.
10. Insect repellent health care
Including anbaoqiujing, keqiu powder, aibao-34, etc.
11. Mildew proof
Due to the high oil content of rice bran, fish meal and other refined feeds, they are easy to oxidize and deteriorate after long storage time. Adding ethoxyquinoline can prevent feed oxidation, and adding propionic acid and sodium propionate can prevent feed mildew. The addition of cinnamon powder not only has strong bactericidal effect, but also attracts food, flavors, and promotes growth.
12. Chinese herbal medicine
Including garlic, wormwood powder, pine needle powder, mirabilite, Codonopsis pilosula leaves, Maifan stone, wild hawthorn, orange peel powder, acanthopanax senticosus, Atractylodes, motherwort, etc,
13. Buffer feed
Including sodium bicarbonate, calcium carbonate, magnesium oxide, calcium phosphate, etc.
14. Seasonability
Including sodium glutamate, edible sodium chloride, citric acid, lactose, maltose, hay, etc.
15. Hormones
Including raw milk record, promoter, yufeiling, etc.
