Grape cracking prevention method

First, using the third mixture (Chinonin 1 bag (10 grams) 72% of agricultural streptomycin 1 bag (15 grams) 15 grams of copper sulfate, with a little vinegar foam, can add Chinon zinc fertilizer and 20 grams of each of Chinon boron fertilizer and about 30 kilograms of water can be sprayed to control three major infectious diseases (viral diseases, bacterial diseases, and fungal diseases). In the spring buds, young shoots of young shoots, flowering, young fruit after Xiehua, can be 10-15 days once, have sprayed twice, can promote new shoots, significantly increase young ears, prevent cobs and brown Caused by the bud, falling flowers and young fruit off. Prevention of viral diseases (foil type, fan blade type, leaf type). In the new leaves, young leaves, young fruit control effect is better than in fruit control effect. Powdery mildew and blackpox have the best preventive effect before onset. Powdery mildew is a disease that causes hard fruit and cracked fruit. The control of the growth period can reduce the incidence of even the fruit period. In the fruit period (small fruit, medium fruit, large fruit), the mixture is used to prevent about three times in succession to prevent premature senescence, secondary detoxification, secondary strong fruit, prevention of viral leaf rolling disease, and white rot disease. Shoot dead and ear brownish. The disease should remove the diseased tip and focus on spraying the main rod so that it will no longer spread the infection. Fungal anthracnose, black rot, powdery mildew, and leaf spot, such as leaf spotting, are to be sprayed and dripping, and sprayed through the leaves. It can prevent rotten and rotten leaves and early leaves, increasing both yield and quality.

Second, with the fifth mixture of calcium (with the third mixture, in Chichenong zinc fertilizer and Chinon fertilizer 20 grams each, only water 3 Jin, while adding a chelating zinc and calcium). Calcium chelate preparation, Qiongsusu 1 bag 10g, Chinon zinc fertilizer 40g, lime 50g, dissolve with 2 vinegar, add 3 jins of water, stir, go to lime slag, pour the clarified water into No. 3 In the mixture. Adding 24 kilograms of water and adding 30 kilograms of water to the plant can strengthen the prevention and control of three major infectious diseases, and at the same time prevent and control non-infectious diseases caused by calcium deficiency, such as split fruit and brown rot. The mixture has the following effects:

1. From the flowering stage to the young fruit stage after the flowering stage, once in 10-15 days, prevent 1-2 times, enhance pollination, increase fruit setting, prevent budding, fall flowers and young fruit fall off. At the same time, prevention of virus caused by stagnation, malformation and black pox, powdery mildew, downy mildew and other diseases. (Note: No. 3 can be used before flowering, but also the fifth mixture can be sprayed), in the fruit period (small fruit, fruit, large fruit) can be controlled about three times, prevent premature aging, secondary detoxification, two The next strongest fruit is the prevention and control of non-infectious fruit cracking and brown rot caused by calcium deficiency, while preventing and controlling three major infectious diseases. The growth period is a concentrated occurrence period of fungal rotten fruit disease and viral leaf disease, and rotten leaves and rotten leaves are basically caused by no infectious disease after the prevention and control. There is also no crack caused by calcium, rotten fruit. Felt disease (also known as sputum), as long as the use of the mixture sprayed through the leaves back (without adding insecticide) control 1-2 times can completely recover the diseased leaf. After the mixture is used to control, the grape particles are large, the green skin is smooth and flawless, the fruit juice is filled, the hardness of the fruit is enhanced, the storage is resistant, the sourness is removed, the astringency and the taste is light and odorless. Sweet and sweet, but without losing its natural flavor. Calcium increases the aroma of the grapes and the flavor of the wine, especially the white wine and the champagne. Because calcium can adjust the acid-base balance, increase sugar content.

2. Prevention and cure of twigs on grapevines (mainly new shoots taken out of the year). The disease is caused by calcium deficiency. The disease does not require special medication control, as long as the fruit period with the mixture to prevent disease, strong fruit, about three times, withered dead, generally does not occur.

3, to prevent pre-harvest fruit drop (results, fruit, fruit) and early leaves. Such fruit drop and early leaf fall are non-infectious physiological and early defoliation caused by malnutrition. The calcium can adjust the nutrition to be stable, so it can significantly prevent pre-harvest fruit drop and early leaf fall, and there is no decline after fruit picking. Protecting leaves from falling off early can catch flower bud differentiation. Flower bud differentiation is completed in summer and autumn, and flower buds no longer reverse after differentiation. Rich and robust flower buds are the basis for high yields in the coming year. (Note: 1, Calcium is used to chelate zinc-calcium, and it cannot use a wide variety of inorganic calcium fertilizers. Crops can only absorb and use organic calcium in the chelated state, and cannot absorb and use inorganic calcium. 2. Disease prevention without chemical pesticides First, it is unnecessary, and the second is counterproductive).

Third, use the sixth mixture to make up the iron (20 grams of Chichennon zinc fertilizer with the third mixture, 40 grams of Chinon boron fertilizer, plus 50 grams of ferrous sulfate, can increase Qiong Su 10 grams ) Irrigation department. No leaf spraying is allowed. While strengthening the prevention and control of three major types of infectious diseases, prevention and control of non-infectious leaf iron deficiency caused by iron deficiency, yellowing, bleaching disease. The root can be fed 1-2 times a year. About 10-15 days after irrigation, the diseased leaves basically recovered and turned greenish green. Valid for 2-3 years. If in the fruit period, spraying with the fifth mixture at the same time, prevent disease and strong fruit, can completely turn the leaves to green, shiny leaf surface shine, pleasing to the eye.

Fill the roots and fill the roots with a sixth or third mixture. For disease prevention and control: 1, viral disease, fruit tree virus disease is the entire tree, prevention and treatment of virus disease to use the No. 3 mixed solution root irrigation, accompanied by spraying on the foliage. Spray treatment does not cure the problem. 2. Dead trees and shoots dead due to infectious diseases, only some of the main stems and roots have not yet died. After rooting in the spring buds, shoots and spikes increased several times. Irrigation 1-2 times a year. Permeate the roots thoroughly. Root soil insects can be added insecticides. 3, prevention of iron deficiency disease, with the No. 6 mixed liquid irrigation roots, in the strengthening of the prevention and control of the three major infectious diseases, while preventing iron deficiency caused by leaf chlorosis, yellowing, bleaching.

4. Control various insect pests: Add 20% extinction (fenpropathrin) in 1-2 solutions (4 ml each), 1-2 bags of 10% imidacloprid (10 grams per bag), spray or irrigation Root pest control. Severe insect pests, double the amount of insecticides. Spray 1-2 times on 1-3 days. Spray once for half a year without insects. The non-insecticide fenpropathrin can be replaced by other pyrethroid insecticides. Flowering period do not add insecticides. In the flower bud sprouting period, Xiehua young fruit pest control effect is good.
