Apple tree “monthly child fat†should be dominated by organic fertilizers, which mainly include farmhouse manures that are fully decomposed and processed or industrially produced commercial organic fertilizers, supplemented by chemical fertilizers. Farmyard manure mostly comes from animal dung, and it is rich in organic matter. When these organic fertilizers are not cooked, their nutrient status is slow, and they cannot be directly absorbed and utilized by the roots of fruit trees. If they are applied, in the process of subsurface decomposing, due to the strengthening of denitrification, heat is easily generated to cause “burnt rootsâ€. †It causes root rot. After the application of organic fertilizer without decomposition in the fall, due to the low soil temperature in autumn and winter, and the mixing with the orchard soil layer, it takes a long time for these organic fertilizers to decompose underground. Under normal circumstances, in the orchard that was applied three years ago and no organic fertilizer was applied in the following years, some of the raw manure was still in its original state. In the second spring, although the ground temperature went up, if there was little rain in the spring, The entering organic fertilizer is still slow to decompose, which requires a large amount of nutrients to supply the flowering results of the tree. However, the limited organic nutrients released by the slowly decomposed organic fertilizer cannot meet the needs of the tree. At the same time, the microorganisms will also consume some of the nutrients (such as nitrogen fertilizer) originally found in the root soil of fruit trees during the decomposed process, and the trees often show malnutrition. After entering the second year of summer and autumn, with the increase of rainfall, the temperature of ground rose rapidly. In the previous year, the decomposition rate of organic fertilizer without decomposition was significantly accelerated, releasing more organic nutrients that could be absorbed by the tree, resulting in tree Accelerated growth, large number of strips, poor coloration of fruits, excess nutrient growth, and poor ability to differentiate flower buds caused a large amount of organic nutrients to be wasted and the nutrient supply of the tree was out of balance. Therefore, the farmyard manure applied to the “monthly manure†must be fully decomposed. Of course, the right amount of fertilizer input is also very important. The "harvest manure" of apple trees should follow the principle of fertilization based on basal fertilizer, which is supplemented by the proper recovery of chemical fertilizers in the key growth period and the application of trace element fertilizer in the foliage.

API Powder (Active Pharmaceutical Ingredient)
Active Pharmaceutical Ingredients refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly.
According to its source,Active Pharmaceutical Ingredients are divided into two categories: synthetic chemical drugs and natural chemical drugs.Chemical synthetic drugs can be divided into inorganic synthetic drugs and organic synthetic drugs. Inorganic synthetic drugs are inorganic compounds (extremely elements), such as aluminum hydroxide and magnesium trisilicate used to treat gastric and duodenal ulcers; organic synthetic drugs are mainly composed of basic organic chemical raw materials, through a series of organic Drugs made by chemical reactions (such as aspirin, chloramphenicol, caffeine, etc.).
Natural chemical drugs can also be divided into biochemical drugs and phytochemical drugs according to their sources.Antibiotics are generally made by microbial fermentation, which belongs to the category of biochemistry.In recent years, many semisynthetic antibiotics are the combination of biosynthesis and chemosynthesis.Among APIs, organic synthetic drugs account for the largest proportion in variety, yield and output value, which is the main pillar of chemical pharmaceutical industry.The quality of API determines the quality of preparation, so its quality standards are very strict. All countries in the world have formulated strict national pharmacopoeia standards and quality control methods for its widely used API
