In the cultivation of fruits and vegetables, the main measures affecting the storability of fruits and vegetables are fertilization and irrigation. Fertilization has a great influence on the quality and storage of fruits and vegetables. Generally used for long-term storage of fruits and vegetables, in the production process, should try to control the amount of nitrogen fertilizer application, especially in the late growth period, should be appropriately increased phosphorus, potassium, calcium fertilizer and boron, manganese, zinc, iron and other trace fertilizer. During the growth period of fruits and vegetables, foliar spray fertilizer technology should be adopted to increase the calcium, boron, manganese, phosphorus and potassium content of fruits and vegetables, reduce the ratio of nitrogen to calcium, and balance the relationship between the elements and nitrogen, thereby enhancing the storage and disease resistance of fruits and vegetables ( It is mainly resistant to physiological diseases. The excessive application of nitrogen fertilizer will often reduce the resistance of fruits and vegetables, shorten the storage time, and increase the decay loss in severe cases. Therefore, organic fertilizers and compound fertilizers containing humic acid are applied in the production of fruits and vegetables. Reasonable irrigation is an effective measure to ensure long-term storage of fruits and vegetables. Generally, irrigation should be stopped 7 to 10 days before harvesting of fruits and vegetables. Otherwise, the storability of fruits and vegetables will be greatly reduced, and the loss of rot and loss of water during storage will increase.
