Li Fang, Fangzhuang Town, Jiaozuo City Q: My family planted several grapes in the yard. Due to insufficient fertilizer and water, the leaves of the plant were yellow, like insects. If you want to apply too little fertilizer, it will affect your health. How can I fertilize it?
Answer: Grapes planted on courtyards are often inconvenient because the garden is narrow or fertilized on the cement floor. Applying organic fertilizers and other manure fertilizers also affects environmental hygiene. The garden grapes are fertilized and can be fertilized by a fertilizing tank that is buried next to the grape plants. The specific method is: When planting grapes, dig l m square planting pits, fertilization. The soil and land should be rich in nutrients, loose, and have good permeability. It is appropriate to accumulate high-quality organic manure and sand by accumulating humus in leaves for many years. Put 20 centimeters thick loam on the bottom of the pit, put a brick on it, place a small jar (diameter 8-12 cm, height 70 cm) on the brick, plant a grape next to the jar, and cover the soil. Fertilizer is dominated by nitrogen fertilizer, and the root absorbs quickly and can fully exert the fertilizer effect. Cover with a wooden lid after fertilization to keep it sanitary.
Fertilization according to this method can apply nitrogen, phosphorus, potash fertilizer and trace fertilizer according to the requirements of nutrition for each growth period of the grape. After flowering, the top dressing of young fruit is still dominated by nitrogen. Phosphorus and potassium fertilizers are used in combination. When the berries start to color, phosphorus and potassium fertilizers are mainly used, and nitrogen fertilizers are appropriately added. After the fruit is harvested, in order to restore the tree vigor and increase plant nutrition, nitrogen, phosphorus, and potassium fertilizers should be mixed. Liquid manure can be used to compile human excrement, cake fat clarifier, calcium superphosphate leachate, as well as soggy ash. To dilute the fat and apply fertilizer, the fertilizer solution should not be too concentrated so as to avoid causing fertilizer damage. Wash the rice, wash fish, rich in nutrition, readily injected, the grapes can be long-lasting.
