Misunderstanding 1: The species with a longer growth period immediately fell away after harvest, and no measures were taken.

Reasons: There is no time for late-maturing varieties to take measures. The reasons for the first two months of deciduous growth are the rapid growth period of the grape root system. The growth of grape roots during this period is not only the basis for preventing freezing damage, but also the conditions for the healthy growth of grapes in the second year. After harvesting, it is an important period to reduce overwintering bacterium source and insect source. Measures should be taken according to the specific conditions of the orchard.

Correct practice: 1. In the late growth stage of the grape, especially in mature period, the leaves have sufficient nutrition to ensure the normal maturation of the grapes, and there are enough nutrients for the mature branches, flower bud differentiation, root growth, accumulation of root nutrition, etc. . 2. According to the climate, pest and disease occurrence, the new high-fat membrane and targeted pesticides are sprayed when the grapes begin to mature to ensure the safety of the leaves in the later period. 3. After the grapes are harvested, spray the general tree guard. Control the propagation and spread of airborne viruses, protect plant tree self-defense reaction instincts, destroy harmful pathogen supply sources, infiltrate eliminate viruses, close viral replication and transmission pathways, and reduce disease recurrence and reactivation rates.

Misunderstanding 2: After the grapes are harvested, the prevention of pests and diseases is deemed unnecessary.

The reason: If pests and diseases can be prevented and treated in time after harvest, the overwintering base of diseases and insect pests will be reduced, laying the foundation for the prevention and control of pests and diseases in the second year, which is an important period for prevention and control. If the defoliation caused by the disease epidemic after grape harvesting not only affects the grape production in the second year, but it may take several years to recover.

Correct practice: In general vineyards must use pesticides, and according to the specific circumstances, use targeted drugs with a new high-fat membrane together, can transform high-toxic pesticides for poisoning, poisoning pesticides for low toxicity, low toxicity pesticides for micro-toxic. The control of pesticides is volatile and elegant, preventing rain erosion, reducing the dosage per acre by half, and improving control effectiveness. Http://
