A course on the latest winter management techniques of Jufeng grape

Jufeng grape can be said to be one of the most popular grape varieties in China. The planting area in our country is also very large, when planting Jufeng grape, we should adjust the management method according to the change of season. Especially when it is low in winter, we should pay more attention to it. So how to manage Jufeng grape in winter? The following editor brings you the winter management technology of Jufeng grape, let's have a look!

1. Soil preparation and fertilization

In winter, we apply enough base fertilizer to the vineyard. Base fertilizer should be based on fully mature farm manure, combined with appropriate amount of chemical fertilizer. Generally, the amount of organic fertilizer is kept at about 7500kg/ mu, and potassium chloride, calcium superphosphate and other fertilizers are the main chemical fertilizers, but it should be noted that there is no available chlorine fertilizer. Then when applying base fertilizer, we should do a good job of land preparation at the same time. In order to improve the drainage and irrigation capacity of the garden, it is best to apply an appropriate amount of organic matter into the soil to improve the soil quality. If the soil is sticky and heavy, then it is all the more necessary to do a good job in soil preparation.

2. Winter pruning

In winter, the winter shearing of Jufeng grape is essential. The pruning of Jufeng grape is different from the common diploid grape varieties. When pruning the Jufeng grapes in the young tree stage, we should pay attention to the principle of light cutting and long release, otherwise in the second year, there may be overgrowth phenomenon, resulting in falling flowers and fruits, and so on. This is also the disadvantage of many people when cutting Jufeng grapes in winter. As for the branches after pruning, the branches should be tied to the shelf in time according to the principle of plastic surgery, and should not be carried out in the spring of the following year, otherwise it will have a great impact on the yield.

3. the work of clearing the garden

Clearing the garden is also a management work that Jufeng grape must do well in winter. After the harvest of Jufeng grapes, clean up the fallen leaves, branches and weeds in the garden in time. Because these things are the main carriers of many germs overwintering, they will pose a great threat to the growth of Jufeng grapes in the second year. Attention should be paid to taking it out of the garden and burying it deeply. Do not use it as fertilizer for convenience, and then spray and disinfect the plant, frame pole and ground with Baumite sulfur mixture and other agents. When the winter buds sprout, they can be sprayed again, which can improve the effect of disease prevention.

4. Timely winter irrigation

After entering winter, we still need to do a good job of winter irrigation. If the soil is very dry, or if the base fertilizer dries quickly after applying the base fertilizer, then winter irrigation should be done in time. Because this can not only accelerate the decomposition rate of organic fertilizer, ensure the conversion rate of fertilizer, but also increase the soil water content, promote plant sprouting, and ensure the flowering and fruiting of Jufeng grape in the coming year. In winter irrigation, it is necessary to give priority to furrow irrigation, if the groundwater level is relatively high, then winter irrigation is not necessary.

The above is a brief introduction to the winter management technology of Jufeng grape. That's all for today's introduction. This article is for reference only. I hope it can help you all.
