The solution of postharvest fruit of peach in greenhouse is to strengthen fertilizer and water, ensure adequate nutrition of the tree, control the temperature and humidity in the greenhouse, control the effects of diseases and insect pests, etc., mainly due to weak tree potential, poor water and fertilizer, pre-flowering malnutrition, not full flower and other reasons. During this period, we should focus on the following points:

1. Strengthen the fertilizer and water to ensure the adequate nutrition of the tree. NP was mainly used in the early stage and competition in the later stage. After topdressing, it was combined with ploughing and watering. If the tree stalk was weak, it could be irrigated with appropriate amount of irrigation.

two。 Control the temperature and humidity in the greenhouse and give the tree the most suitable growth environment. The requirements for post-anthesis fruit expansion period are as follows: temperature 8 ℃-26 ℃, hard core temperature 10 ℃-28 ℃, 15 ℃-30 ℃ in the first 3 weeks of harvest, and the humidity after anthesis should not exceed 60%.

3. Control diseases and insect pests and improve fruit quality. The nectarine in the greenhouse grew in the microclimate environment, and the disease and pest control was good last year. This year, there are few diseases and insect pests, and the main prevention is to prevent the diseases and insect pests. The fungicides are 80% of Dasheng MMI 45's 800 times liquid or 50% carbendazim or Bordeaux solution. Insecticides are used: carbendazide, aphid lice net, fenitrothion.
