Latest Winter Management Techniques and Methods Tutorial for Kyoho Grapes
Kyoho grapes can now be said to be one of the most popular grape varieties in our country. Their planting area in our country is also very large. When growing Kyoho grapes, we must adjust our management methods according to the changes of the seasons. Especially during the low temperatures of winter, even more attention must be paid. So how should Kyoho grapes be managed in winter? Below, the editor brings you the winter management techniques for Kyoho grapes. Let's take a look!
1. Land preparation and fertilization
In winter, we apply sufficient base fertilizer to the vineyard. The base fertilizer should mainly be fully decomposed farmyard manure, combined with an appropriate amount of chemical fertilizer. Generally, the application rate of organic fertilizer is kept at about 7500kg/mu, and the chemical fertilizer is mainly fertilizers such as potassium chloride and superphosphate, but note that there must be no quick-acting chlorine fertilizer. Then, when applying the base fertilizer, land preparation work should also be done well at the same time. Deeply plow and mature the soil in the orchard to improve the drainage and irrigation capacity of the orchard. It is best to apply an appropriate amount of organic matter into the soil to improve soil quality. If the soil is relatively sticky and heavy, then land preparation work should be done even better.
2. Winter pruning
In winter, the winter pruning work of Kyoho grapes is essential. The pruning of Kyoho grapes is different from the common diploid grape varieties in daily life. When pruning young Kyoho grape trees, attention should be paid to the principle of light pruning and long training, otherwise in the second year, excessive vegetative growth may occur, leading to flower and fruit drop, etc. This is also a shortcoming of many people when winter pruning Kyoho grapes. As for the branches and vines after pruning, they should be tied to the trellis surface in time according to the shaping principle, and this should not be done in the second spring, otherwise it will have a relatively large impact on yield.
3. Orchard cleaning work
Orchard cleaning work is also a management task that must be done well for Kyoho grapes in winter. After the Kyoho grapes are harvested, the fallen leaves, fallen branches, weeds and other things in the orchard should be removed cleanly in time. Because these things are the main carriers for many pathogens to overwinter, and in the second year, they will pose a great threat to the growth of Kyoho grapes. Note that they should be concentrated and taken out of the orchard, then deeply buried or burned. Do not use them as fertilizer for convenience, and then use agents such as lime-sulfur mixture to spray and disinfect the plants, trellis poles and ground. When the winter buds sprout, they can be sprayed again, which can improve the disease prevention effect.
4. Timely winter irrigation
After entering winter, we also need to do winter irrigation work well. If the soil is very dry, or if the base fertilizer dries out relatively quickly after being applied, then winter irrigation should be carried out in time. Because this can not only accelerate the decomposition speed of organic fertilizer and ensure the conversion rate of fertilizer, but also improve the soil water content, promote plant sprouting, and ensure the flowering and fruiting of Kyoho grapes in the coming year. During winter irrigation, furrow irrigation should be the main method. If the groundwater level is relatively high, then winter irrigation may not be carried out.
The above is a brief introduction to the winter management techniques for Kyoho grapes. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
