Bagging apple has got disease reason
Editor's note: In recent years, most apple production areas have adopted apple bagging technology and have received the expected results. However, due to the abnormal climate change in recent years and the difference in the level of fruit and vegetable application bagging technology, many problems have arisen in bagging apples. The reasons are summarized below for reference by farmers. Reasons for heavy cracking of bagged apples First, the cause of apple's “shoulder†cracking is heavy. During the later period of apple growth, when the pulp cells continue to expand, if the temperature drops at the moment, the peel will shrink, and the still-puffy pulp cells will spread the peel. Cause cracks in the skin. Apple's "shoulder," because the skin is tender, so heavy cracks. Second, the cause of the apple crack crack Picking the bag is not timely or Apple harvesting is not timely, the cracks will increase. If the apples are pulled, they will not be harvested within 7 days after bag removal. More than 20% of apples will crack. In addition, there was more rainfall, and the apple cracked heavily. After picking the bag, if there was dew every day and the fruit surface did not dry before 11am, the apple cracked heavily; the humidity in the ground was high, the crack in the apple was heavy; the temperature was unstable, and the crack in the apple was heavy; 7-8 In apple orchards, where the application of nitrogenous fertilizer is applied on a monthly basis, there are many cracks in the apples. Reasons why bagging apples are not shrinking I. Causes Long-term drought, lack of water, weak apple orchard and poor ventilation, high temperature, low humidity apple orchard, Apple prone to bagging after a short period of shrinking phenomenon. In particular, the double-layer paper bag with thick outer layer and resistant to rain and the inner layer of non-calendered black paper, there is no moisture in the bag on weekdays, and the temperature in the bag during high temperature is as high as 50°C. The moisture in the apple flows back to the leaves and causes the apple. Growth stops or even shrinks. Second, prevention and control technology (a) timely watering. For bagging apple orchards on barren lands, hillside lands, and highland lands, timely watering should be conducted in the dry year. (b) Avoid using purple and red plastic film bags and double-layer paper bags with non-calendered black paper on the inner layer. (3) Strengthen the management of apple orchard. A reasonable load will allow the apple orchard to be airy and light and do not advocate excessive ringing. Why do bagging apples yellow and not colored I. Excessive application of nitrogen fertilizer, especially in July-August, the phenomenon of yellowing of apples after picking bags will appear after too much nitrogen fertilizer or topdressing nitrogen fertilizer. Second, boron poisoning If too much topdressing borax will lead to boron poisoning, so that yellowing of apples is not colored, and once this happens, it may be difficult for three consecutive years of apple coloring. Third, circumcision heavy apple early defoliation serious, lack of nutrient accumulation of the tree, in this case, many growers continue to increase girdling efforts, resulting in many apple orchard apples yellowing phenomenon. Fourth, the continuous high temperature for more than 30 °C for 5 consecutive days, bagging apple bag temperature exceeds 60 °C, which affects the formation of coloring substances. 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.
