Don't let go after management of grapes

After the harvest of the grapes to the deciduous period, there are about four or five months of growth, and the tree is restored. Therefore, the management of grape harvesting is still very important, mainly to do the following work.

Fertilization in autumn adopts the ring ditch fertilization method for juvenile trees, that is, the annular fertilization ditch 20~30 cm deep in the periphery of the trunk, and the fertilization ditch fertilization method for the adult vines according to the situation, that is, away from the trunk At 30 to 50 cm, open a shallow to deep trench to each side. Generally, 3000 to 4000 kg of decomposed pigs and cows are used per mu, or 4000 to 5000 kg of high-quality soil and fertilizer are applied to the ditch, and then the soil is covered.

If the weather is dry and rainless after harvesting, it will cause premature death and shedding of the leaves, which is not conducive to the accumulation of nutrients in the tree. In the case of autumn drought, it is necessary to pay attention to drought-resistant irrigation. If there are 10-20 days of dry and sunny days in a row, irrigation is generally required, and trench irrigation and acupoint irrigation can be used. It is strictly forbidden to flood irrigation, drip irrigation and long-term irrigation.

The main focus of pest control is to control downy mildew, powdery mildew, black pox and rust. After the fruit is collected, the first dose of the medicine is sprayed, and then sprayed once every two months, even for 2-3 times. The available agents are: 40% Ethylphosphorus aluminum wettable powder 300 times solution, 60% Dyson zinc powder 500 times solution, 64% antivirus 矾 500 times solution and other grape diseases. At the same time, 2.5% deltamethrin should be used to control a variety of pests such as chafer, grape hawk moth and diptera.
