Safe overwintering method for citrus shatangju and safe overwintering preparation

Abstract

The invention relates to a safe overwintering method for citrus shatangju and a safe overwintering preparation. The method comprises steps as follows: a safe overwintering preparation is supplemented to fruit trees in different growth periods and fruit growth periods of citrus shatangju fruit trees; the safe overwintering preparation comprises elements in parts by weight as follows: 10-20 parts of nitrogen, 20-50 parts of phosphorus, 15-50 parts of potassium, 5-30 parts of sulfur, 1-5 parts of boron, 0-6 parts of zinc, 2-8 parts of ferrum, 1-6 parts of manganese and 0-0.3 part of molybdenum; the fertilization method of the safe overwintering preparation adopts root fertilization or leaf surface spraying; when leaf surface spraying is adopted, the application amount is 300-700 g for each mu each time, and fertilization is performed for 3-6 times; and when the root fertilization is adopted, the application amount is 100-200 kg for each mu, and 100-200 kg of fertilizers are applied for 3-4 times. By means of the method, various necessary nutrition ingredients can be provided for the citrus shatangju fruit trees and fruits, nutrient balance is kept, and the cold resistance and freeze-proofing capability are increased; and the pesticide use amount can be greatly reduced, even pesticide is not used, plant diseases and insect pests can also be inhibited, and the safe overwintering preparation is very suitable for producing pollution-free and organic food.

Problems solved by technology

But in fact, the application of nitrogen alone is easy to cause the occurrence of diseases and insect pests, that is, the greater the amount of nitrogen used, the more serious the occurrence of diseases and insect pests, especially the application of nitrogen fertilizer alone, the situation will be more serious, not only will cause the epidemic of various diseases, but also cause All kinds of special-effect pesticides lose their control effect; and when nitrogen, phosphorus, and potassium are applied at the same time, if the amount of phosphorus and potassium is unbalanced, the effect of nutrition and disease prevention is also limited. In addition, the traditional method also ignores the relationship between the above elements and Reasonable collocation of other medium and trace elements
