The method to solve the rot of fruit trees
Improve fertilization methods and strengthen soil management. Application of bio-organic fertilizer, compound fertilizer, whether it is a ring or radial digging trenches, first, more radial ravine (8-10); Second, long-ring ditch to be long; Third, deep and 30 cm deep . Fertilizers are widely exposed to the roots of fruit trees. For soil management, it is necessary to insist that the whole orchard be done once a year in the spring to keep the live soil well ventilated and prevent the root system from being introduced to the surface. Apply base fertilizer in autumn to increase storage and nutrition. It is necessary to fully understand that fruit trees have adequate nutrients for storage in winter, which is both the basis for ensuring the robustness of the tree and the key to ensuring the high yield and quality of fruit in the following year. Harvested fruit trees such as cherries, apricots, peaches, plums, walnuts, grapes, early and mid ripe pears, apples, etc., will be completed in September. Chestnut and late-maturing varieties of apples, pears, peaches and other fruit trees, after harvesting in October, must grab time to apply base fertilizer, good sensation, after the fall can also bring fruit basal. Dredge the drainage system to prevent water accumulation in the orchard. In the orchard through the orchard, increase the height of 15-20 cm around the trunk to form a dorsal shape to prevent stagnant water after the heavy rain. The rows of fruit trees are lower than the 15-20 cm canopy below the canopy, and the dry days can be watered smoothly. After heavy rain, they can be drained smoothly. Strengthen soil improvement and scientifically replant young trees. If the roots of rotted roots are dead trees, they must dig large holes and fill the top and bottom with organic matter such as topsoil, sand and weeds, and straw to create a loose layer of living soil. In the fruit trees where the roots were dead, many harmful germs remained in the ground, and small fruit trees were planted. First, it was not easy to survive. Second, even if they survived, they did not grow. Disclaimer: Some articles in this website have been transferred from the Internet.

Acetyl salicylic acid is synthesized through chemical process and purified to a specified purity. The synthesis of acetyl salicylic acid is made by adding various excipients, such as fillers, adhesives, disintegrating agents, etc., and then pressing it into tablets. The production of apis is generally either pure chemical synthesis, biological fermentation, or semi-synthesis, with biological fermentation followed by extraction followed by synthesis. Not all pharmaceutical enterprises make API by themselves, and many manufacturers do not have the scale to produce API. Even if there is large-scale production, the cost of production may be much higher than that of procurement. Therefore, most manufacturers buy bulk drugs, and then make preparations, so that the production of drugs can be completed without a very large scale. At present, China and India have become the two largest API producers in the world. Many European and American pharmaceutical companies, even some of their own original drugs, will give up the production of API as the patent expires and the market matures, and turn to purchase apis from China and India,API production generally go through laboratory, generated through laboratory bottle container canister, taking after successful, pilot magnification, which is to enlarge the quantity of the production, then no problem tends to be faced with a lot of small scale experiment, a very simple example, the heating process, due to the relatively small amount in the laboratory, uneven heating cases is less, But if it is scaled up to a few tons of pot, at this time the heating may be not hot in this place, where the paste pot, at this time you need to stir, but the speed of mixing is appropriate, this process needs to calculate or grope. Finally from the pilot test, and then to the formal production, the volume of further amplification, and will face a lot of new problems. Therefore, although some drugs are generic, the research and development of the whole process from small test, pilot test to the final mass production is indispensable, so even generic drugs have very high research and development costs. api meaning,api products to buy,best api products,cheap api products,best buy products api,best api products Shaanxi YXchuang Biotechnology Co., Ltd , https://www.peptide-nootropic.com
