1. Trimming (summer shearing) after pruning the big cherry after picking is a critical period for cultivation and management. The main purpose is to adjust the tree structure, improve the ventilation and light transmission conditions inside the crown, concentrate nutrition, and promote flower bud formation. Firstly, the branches of diseases and insects, pendulous branches, over dense branches, cross branches, thin and weak branches, overlapping branches, and auxiliary branches and strong branches that have severely affected light and have no reservation value were removed from the base.
In addition, the method of "putting it out and retracting it" should be adopted for the backbone sticks to maintain the growth of the backbone. After the result, the debilitated result is retracted, rejuvenated, and retracted to the strong buds. Big cherries have strong polarity and should be removed in time to remove densely crowded branches (broom sticks) and light to enter the crown. To achieve "the periphery is not crowded, the guilt is not empty".
2. Strengthen soil fertilizer management After the cherry has been picked, the tree consumes a lot of nutrients. To restore the tree vigor and promote flower bud formation as soon as possible, timely fertilization and watering should be used. Adult trees, 50 kg of organic fertilizer applied per plant, mixed with urea 0.6 ~ 1.0 kg, or topdressing special fertilizer for fruit trees 1.5 ~ 2 kg. Appropriate amount of water after fertilization.
At the same time, foliar spraying of 0.3% urea + 0.3% potassium dihydrogen phosphate 1 ~ 2 times. In addition, after the watering, it is necessary to loosen the soil and remove the weeds from the trees. The rainy season should be drained in time. The soil is too wet for ploughing and drying to increase the permeability of the soil, create good external conditions for the growth of big cherries, accumulate nutrients, and lay a foundation for the bumper harvest of the next year.
Before the onset of the rainy season, spray 1:1:200 of the same amount of oxazolol Pol to protect the leaves. If not, use the difenoconazole.
3. Spraying paclobutrazol paclobutrazol on leaves is an effective measure to promote flowering. In mid-June to early July, the results of less vigorous growth of the tree spray 1 to 2 times 15% of paclobutrazol 200 to 300 times the liquid, can inhibit the growth of new shoots long, so that branches grow moderately beneficial to the formation of flower buds.
4. Diseases and Pest Control After the cherry has been picked, we must do everything possible to protect the leaves. The main diseases are leaf spot and perforation, which can be controlled by 1000 times of thiophanate-methyl and 3000 times of 75% of agricultural streptomycin.
Insect pests mainly include thorn moths, ulnar catfish, and boat-shaped caterpillars, which can be sprayed with 2000 times liquid to kill them for treatment. If there is a red and white spider, it can be treated with azoline 1500-2000 times or dying net 2000 times. The aphid can be used to remove 3,000 times of liquid and the effect is good.
For the prevention of Cerambyceps, scale insects, large green leafhoppers, and brown spot, perforation can be used. 4% chlorpyrifos 1500 times ten thioprostol 1000 times 10 times cumylazole 1000 times spraying.
5, flow glue sticks flow glue is a phenomenon often occurred in stone fruit trees. Heavy glue can cause the leaves to be yellow, twigs dead, tree weakness, and even the death of the whole tree, causing plastic flow due to freezing, insect, disease, locust, mechanical damage caused by flow plastic, plastic flow, dry flow plastic It is generally considered as a physiological disease.
From June onwards, the onset of the rainy season has increased. For colloidal control, we should avoid tree wounds and insect mouths, prevent and treat pests in time, minimize tree trauma in the management process, apply winter white sticks to prevent freezing damage and daily burning, strengthen orchard drainage, and reduce the degree of fluid leakage. On the branch where the glue flows, it is necessary to timely cure, scrape the glue, and apply a fungicide to the wound. Http://Content/1a2f8ac5-884f-4a08-8b67-c5b81eedbd54?cType=2
Active Pharmaceutical Ingredients
Active Pharmaceutical Ingredients(API) 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. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
