Shine-Muscat late management points

As the temperature gradually decreases, the autumn application of Shine-Muscat base fertilizer work has ended. Subsequent field management matters are less, but there are still some management work that needs to be focused on.

1. Remove the shed film. On the one hand, the removal of the canopy film can make direct sunlight to the buds and promote the differentiation of flower buds. On the other hand, the subsequent field management needs to spray stone sulfur mixture. Because it is an alkaline pesticide, spraying on the shed film may shorten the life of the shed film. However, it should be noted that after removing the shed film, the rain will increase the risk of pests and diseases. Therefore, in areas with more rain and more serious diseases and pests, the shed film can be removed without removal or later after the temperature decreases.

2. Fill with water. The specific heat capacity of water is large, and it is a natural cold protection agent. Flood the soil with water before cooling to increase soil moisture. It can effectively improve the cold resistance of the soil, help the grapes through the low temperature period, and reduce the occurrence of freezing damage.

3.Remove the old skin. In addition to the main purpose of the old skin is to expose the bacteria and eggs in the bark gap, so that the garden is more thorough. Therefore, you can peel off the old skin before cleaning the garden.

Peeling time is not recommended too early, in the peeling if improper operation will damage the bark, the formation of wounds, resulting in wound flow. For small trees, the old skin of small trees is shallow, there is no need to peel, once peeled will lead to faster water loss, resulting in a greater impact on the tree. Therefore, it is recommended that trees more than five years old should be peeled.

4. Winter cut. After the temperature drops below 7℃, the grapes can be pruned when they enter the dormant period. Determine whether to prune one or two buds according to the local climate and cultivation pattern. According to the planned output to determine the amount of branches. Some overdense and weak branches should be cut to avoid the prevention and control of diseases due to poor ventilation in the coming year.

5. Clean the garden and paint white. Stone sulfur mixture is a relatively cost-effective garden medicine, at this time can be used 5 beaum stone sulfur mixture for garden. The garden can effectively reduce the base of pests and diseases in the garden, and the prevention and control of pests and diseases in the coming year is very important, so the garden needs to be carefully and thoroughly cleared. The weeds and branches can be cleared out in advance, and the tree trunks, trellises, and ground in the garden can be comprehensively disinfected.
