In the winter, the leaves of the Kyoho grape have fallen off. It seems that there is nothing wrong with the appearance. In fact, there are many things that should be done at this time:
1. Take time to apply the base fertilizer. The base fertilizer is mainly based on decomposed farmyard manure, supplemented by chemical fertilizers, generally 7-8 kilograms of organic fertilizer applied per mu, potassium chloride or potassium sulfate (preferably potassium sulfate) 10-20 kg, superphosphate or calcium magnesium phosphate 50 For kilograms, do not add quick-acting chlorine fertilizer when applying base fertilizer.
2, winter pruning. The winter shears of Kyoho grape are different from the diploid grapes such as white banana and Kangbaier. Juvenile jujubes should be lightly cut and long-lasting, otherwise the coming year will be long and the flowers will fall and fall. After the pruning, the branches should be tied to the frame in time to form the whole tree. Do not wait until the spring comes to seduce.
3. Deeply plow the soil. It can be combined with the application of base fertilizer to deepen the soil in the garden and to arrange the drainage system. It is best to combine some organic matter with deep soil to improve the soil. This is good for root development and plant growth. For the viscous yellow soil, it should be deep-turned and improved. It is conditional to put some dregs or straw, hull slag, etc. when deep-turning the soil, so that the tillage layer is loose and breathable and inhibits weed growth.
4. Qingyuan. Mainly to remove the leaves, weeds, etc., and burn them intensively (cannot use the leaves as fertilizer). Spray the giant peaks and branches, the poles and the ground with the Bamei 5 degree stone sulfur mixture. When the winter buds sprout at the end of February, spray the cloth with Bamei 3 degree stone sulfur mixture again. This has a multiplier effect.
5, winter irrigation. Winter irrigation can be carried out in gardens where severe drought or application of organic fertilizers is quicker to seep. This not only dissolves the organic fertilizer, but also allows the fertilizer to penetrate into the soil evenly, and also keeps the soil moist and improves the germination rate. Winter irrigation is better with furrow irrigation (water can be naturally infiltrated after the flat surface), and the water network with higher groundwater level is not necessarily winter irrigation.
6. Perform frame finishing or other miscellaneous work.
