Longan results in the tree before harvesting
Methods Before the harvesting of longan, the fertilizer was applied 15 to 20 days before harvesting. The main fertilizer was NPK, the plants above 5 years old, or the trees with 50 kg or more, and each application of NPK (15-15-15) ) Potassium sulfate or nitrate-based or pure sulfur-based compound fertilizer 0.75 ~ 1 kg, evenly spread on the topsoil under the canopy after rain. After harvesting the fruit in the longan, the post-harvest fertilizer is applied within 5 to 10 days. The quick-acting quick-acting nitrogen fertilizer and potassium fertilizer are mainly used. Each plant applies 0.75-1.00 kg of urea and 0.50-0.75 kg of potassium sulfate. After rain, it is evenly applied on the topsoil under the canopy. Just fine. In addition, at the same time as the root fertilization, it is necessary to carry out the top dressing. Spray a 0.2% to 0.3% potassium dihydrogen phosphate, 0.1% magnesium sulfate, and 600-800 times amino acid active liquid fertilizer mixture on the leaf surface before fruit picking. After fruit picking, spray 2~3 times of 0.1% magnesium sulfate, 0.2% urea, 0.3% potassium dihydrogen phosphate, 800-1000 times humic acid active liquid fertilizer mixture, spray once every 7-10 days, evenly spray wet All the branches and leaves inside and outside the crown are suitable to start with drops of water. Supplementing various nutrients from the foliage helps to stabilize and rejuvenate the tree. Disclaimer: Some articles on this website are transferred from the Internet.

They can be natural substances or chemical compounds obtained through chemical synthesis. Here are some common chemical raw materials:Sodium lauroyl glutamate,carbomer,5-hydroxytryptophan(5-HPT), Triclosan,fenbendazole,Tetrabutylammonium bromide Etc. There are many kinds of chemical raw materials, including inorganic chemical raw materials and organic chemical raw materials. Inorganic chemical raw materials include various metals and non-metallic elements, oxides, acids, bases, salts, etc. For example, common sulfuric acid, hydrochloric acid, sodium hydroxide, etc., are widely used in many industrial fields. Metals such as iron, copper, aluminum, etc. are important raw materials for the manufacture of various metal products.

Organic chemical raw materials include hydrocarbons, alcohols, aldehydes, carboxylic acids, esters and so on. For example, ethylene, propylene, etc., are the key raw materials for the synthesis of polymer materials; Methanol, ethanol, etc. are indispensable in chemical industry, medicine and other fields.
These chemical raw materials play an important role in various industries. In the chemical industry, they are the cornerstone of the production of various chemical products; In the field of materials, it is used to manufacture plastics, rubber, fibers, etc. In the pharmaceutical industry, to provide the basis for drug synthesis; In the field of agriculture, fertilizers and pesticides also rely on specific chemical raw materials.
The quality and purity of chemical raw materials have a direct impact on the performance and quality of the final product. With the development of science and technology and the continuous improvement of product requirements, the research and development of chemical raw materials are also continuing to advance to meet the increasingly diversified and refined needs.
