Techniques for Winter Management of Jufeng Grapes
Jufeng grapes are one of the most popular grape varieties in China. They are also extensively planted in the country. When planting Jufeng grapes, the management methods should be adjusted according to seasonal changes. This is especially important in winter when temperatures are low. So how do you manage Jufeng grapes in winter? The following is the winter management technique for Jufeng grapes brought to you by the editor. Let's take a look!
Soil Preparation and Fertilization
In winter, we apply sufficient base fertilizer in the grape garden. The base fertilizer is mainly composed of farmyard manure, supplemented with an appropriate amount of chemical fertilizers. Generally, the application rate of organic fertilizers is about 7500 kg/acre, with main chemical fertilizers being potassium chloride, superphosphate, etc., but it is important to note that fast-acting chlorine fertilizers should not be used. At the same time, good soil preparation work should be done. The best way to improve the garden's drainage and irrigation capabilities is to apply an appropriate amount of organic matter to the soil to improve soil quality. If the soil is sticky and heavy, good soil preparation work should be done.
Winter Pruning
In winter, pruning Jufeng grapes is essential. The pruning of Jufeng grapes is different from that of diploid grapes. When pruning young Jufeng grapes, the principle of light pruning and long release should be followed; otherwise, excessive growth may occur in the second year, leading to blossom and fruit drop. This is a common mistake made by many people when pruning Jufeng grapes in winter. For pruned branches and vines, they should be promptly tied to the trellis according to the principle of shaping. It should not be done in the spring of the following year, or the yield will be greatly affected.
Garden Cleaning
Garden cleaning is also a management task for Jufeng grapes in winter. After Jufeng grapes are harvested, it is important to promptly clear the garden of fallen leaves, branches, and weeds. These materials are the main carriers for many pathogens to overwinter, and in the second year, they will pose a significant threat to the growth of Jufeng grapes. We should pay attention to removing them from the garden and burning them deeply. Do not use them as fertilizer for convenience, and then spray plants, stakes, and the ground with a Bordeaux mixture and other chemicals for disinfection. After the winter buds have sprouted, another spray can be applied to improve disease prevention.
Timely Winter Irrigation
In winter, we should do a good job of winter irrigation. If the soil is very dry, or if it dries up quickly after applying the base fertilizer, winter irrigation should be carried out promptly. This can not only accelerate the decomposition rate of organic fertilizers and ensure the conversion rate of fertilizers but also increase the soil moisture content, promote plant germination, and ensure the flowering and fruiting of Jufeng grapes the following year. Winter irrigation mainly involves furrow irrigation. If the groundwater level is high, winter irrigation is not necessary.
