1. After the harvest of the fruit under the clear tree, timely collection of dead branches, fallen leaves, rotten fruit, weeds, etc. in the orchard will be concentrated or burned, which will eliminate a large number of overwintering germs and pests.
2. Turning the tree plate deep to plough the tree plate is not only an important measure to improve the soil and promote fruit tree production, but also an effective method to eliminate overwintering pests and diseases. Through deep turning, pests (such as peach borer, peach aphid, etc.) and pathogens that overwinter in the soil can be turned to the surface and frozen, dried or eaten by natural enemies, causing some to dry and curl on the ground. Weeds and weeds in the winter over the germs and pests (such as roll moths, aphids, red spiders, etc.) are buried underground, because they can not normally emerge as a feather and suffocate, thereby reducing the overwintering base.
3. Scrape the bark. As the saying goes: "Pears must be eaten and the bark scraped." In the trunks of fruit trees, cracks in the skin, and cracks in trunks, a large number of wintering germs and pests are often lurking, and winter bark bark has a good control effect on various diseases and insect pests. Comprehensive surveys have revealed that 80% to 90% of overwintering larvae are reduced in scraped orchards, larvae of Mythimna separata, and P. sinensis, and 60% to 80% in apple borerworms and pear carps. Hawthorn red spiders are reduced by 70% to 80%.
4. Applying the tree trunk to coat the white trunk in winter not only prevents the sunburn and frost damage of the fruit tree, but also eliminates a large number of pathogens and pests that overwinter on the trunk. The proportion of whitening agent is generally: 10 parts of lime, 2 parts of lime sulfur, 1-2 parts of salt, 2 parts of clay and 35-40 parts of water. The time for whitening is preferably 2 times, the first time after deciduous fruit trees before the soil freezes, and the second time in early spring.
5. The tying of grass uses the selectivity of pests to overwintering sites. After the fall, the grass is tied to a large branch of the fruit tree or broken into sack pieces to trap pests and larvae for overwintering and then to concentrate. According to the survey, this method has a 47% to 78% trapping effect on the apple fruit and fruit borer, and it is also very common on red spider mites, jujube armyworm, spiny leaf miner, apple leaf roller moth, and leaf roller moth. A good trapping effect, especially when the density of overwintering worms is greater in the year, is more effective in trapping.
6.Spraying deciduous fruit trees During dormancy, spray 1-2 times diesel oil containing 4% to 5% diesel oil and Pometo 5 degree lime sulfur to kill various species of scale insects, red spiders, and apples that damage fruit trees. Diseases, pear tree scab, grape black spot disease, etc., all have significant control effects.
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.
