In the management of grape production, the contents of the management are different in different mature varieties.
Grapes of early maturing varieties should focus on the management of pests and diseases and the restoration of tree vigor. After the grape is harvested, it is necessary to promptly clear the garden, collect the remaining diseased fruit, diseased fruit branches, diseased fruit leaves, etc. in the park for deep processing. After the cleaning, the bactericide such as Bordeaux mixture or lime sulfur can be used to spray the whole garden. Shi (but Bordeaux mixture and lime sulfur can not be combined, rotation should also be used at a certain time interval) to eradicate and reduce the park pest density.
Tree vigor restoration, it is necessary to apply good post-harvest fertilizer and promote tree vigor to resume as soon as possible. Generally, 15 kg of compound fertilizer is applied in Mushi. If the relative tree vigor is strong, it can be applied less or not to prevent the shooter from being young and consume nutrients.
Medium-maturing varieties should focus on management to promote coloring and promote maturity. At this stage, the flesh begins to soften, the sugar content gradually increases, and the acidity decreases. In order to promote the coloration of berries, potassium fertilizer is used as the main fertilizer. For denser leaves, the old leaves under the ear can be removed, and bags can be removed to increase the light. For the more prosperous gardens, girdling measures can be taken to promote the maturation.
For some hard-to-color varieties, consider laying reflective film to increase the amount of light. From the perspective of fruit food safety, we should pay attention to the safety period for the use of pesticides. The use of drugs should be stopped 20 days before the market launch of grapes. At the same time, we must do a good job of preventing birds and animals.
Late-maturing varieties of grapes and berries need adequate nutrition during their second expansion. Therefore, the management of late-maturing varieties should increase the use of fertilizers, fertilizers should be increased by applying phosphorus and potash fertilizers, and fertilization methods should pay attention to applying foliar fertilizers in addition to roots. Under normal circumstances, 25 to 30 days before harvest, 15 to 20 kilograms of each of phosphorus and potassium fertilizers are applied, and potassium dihydrogen phosphate is applied to the leaves for 2 to 3 times.
The above is the content of the management of different maturities during the maturation period. In the common management, we must grasp the following aspects:
Diseases and pests control The key diseases to prevent this period are gray mold, white rot, anthrax, brown spot, downy mildew and so on. Available with 80% mancozeb WP 800 times, 78% POM WP 600 times, 80% Bordeaux WP 400 times, or 10% Difenoconazole Granules 2000 times liquid protective fungicides alternately sprayed, sprayed once every 10 days. The downy mildew was found to be sprayed with 2,500-fold of dimethomorph, or 72% of cream urea manganese zinc, 700-800 times.
Moisture control Soil moisture is the focus of management during this period. Excessive drought or lack of water in the soil will affect fruit enlargement and plant growth. Excessive soil moisture will easily cause rot and cracking. In the hot season, it is also a relatively rich period of rain.
Therefore, the grapes cultivated on the open soil should effectively manage the soil moisture management. When the weather is dry, it is necessary to timely irrigate the drought, but avoid flooding; in the event of continuous rain, it is necessary to do a good job in the drainage and stain reduction in the park. In order to maintain a more balanced soil moisture content, crop straws can be used at the roots of grapes, which can effectively control the water in the garden and effectively prevent and reduce the occurrence of cracking.
The management of dendrite needs to control the growth of branches, maintain proper leaf curtains, control the apical dominance, reduce the ineffective consumption, improve the ventilation and light transmission environment, and promote the fruit ripening and flower bud differentiation. Especially before the fruit matures, it is necessary to control the growth of shoots, regulate the growth of shoots and the contradiction of results.
To continue to control the picking, cutting, and controlling the growth of the shoots. In addition, the removal of old leaves, base leaves, yellow leaves, and tendrils is conducive to ventilation and light transmission, promoting the coloration of berries, and saving tree nutrients.
The prevention of natural disasters and the prevention of severe weather such as typhoons, heavy rain, and hail are also an important task of management, and must be highly valued and guarded against. Before severe weather occurs, it is necessary to take appropriate precautionary measures according to the growth of the grapes to reinforce the scaffolds; to tie loose branches without binding; for excessive shoots, proper pruning should be done. May reduce the typhoon's damage to the tree.
