1. Fruit tree topdressing fertilizer, we must first know the absorption of fertilizer by fruit trees, mainly by root hair in the root system. Therefore, spraying new high-fat membrane with fertilizer in the concentrated distribution area of ​​root hair can improve the utilization rate of fertilizer and promote the rapid growth and increase of yield of fruit trees.
2. If the fruit tree is topdressed with fertilizer, it should be based on the edge of the canopy projection or a little further away. Do not be too close to the trunk, because the trunk is thick and the roots and root hair are less, which is not conducive to the absorption of fertilizer.
3. Fruit trees are topdressed with fertilizers, and the following principles are deeply grasped: fruit trees with deep root distribution should be properly applied, and shallow application; organic fertilizer decomposition is slow, but the fertilizer application period is long, and deep application, fertilizer mobility is large, For shallow roots; for example, for deep-rooted fruit trees such as pear trees, the application of organic fertilizer should be 40-60 cm in depth, and for shallow-rooted fruit trees such as plum trees, organic fertilizer should be applied to a depth of 30-40 cm. Spraying a new high-fat film after fertilization improves fertilizer efficiency.
4. Fruit trees are topdressed with fertilizers. For orchards that are closed or closely planted, they can be applied between rows and between plants. It is best not to hurt or damage large roots, so as to fully exert fertilizer efficiency, improve fertilizer utilization, and increase production and income. purpose.

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
It can promote fat digestion and absorption, protect liver and gallbladder, improve livestock and poultry health and improve feed utilization.
2. Acidifier
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.
5. Promote growth
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.
Vitamin A Powder, Lactose Powder, Oxytetracycline Dihydrate Powder, Vitamin D3 Powder
