Pre-harvest management method for slowing down softening of muskmelon fruits

Abstract

The invention belongs to the technical field of muskmelon management and particularly relates to a pre-harvest management method for slowing down softening of muskmelon fruits. The method comprises the following steps: treatment of muskmelon seeds, management in two weeks after flowering, management of a reticulation forming period and pre-harvest 48-hour management. Compared with the prior art, the method has the advantages that the root activity of seedlings can be improved, and the stem diameter of a plant can be effectively increased, so that the cultivation of strong seedlings is facilitated; the content of hydrogen peroxide of the plant can be favorably increased till a young fruit period of muskmelons after flowering, so that the disease resistance of the plant is improved, and fungus infection to the plant in the period can be avoided; in the reticulation forming period, the deposition of lignin of the plant can be promoted, so that the permeation and extension of diseases can be prevented; the whole plant is sprayed with jasmonic acid methyl ester solution in 48h before harvest, so that the muskmelon fruits have a certain firmness, and the fruit firmness and the content of protopectin when the muskmelons are harvested can be effectively improved, therefore, the purpose of slowing down the softening of the muskmelon fruits is achieved.

Description

technical field

[0001] The invention belongs to the technical field of melon management, and in particular relates to a preharvest management method for slowing down the softening of melon fruits. Background technique

[0002] Melon, also known as cantaloupe or sweet melon, is one of the top ten fruits in the world. It has a long history of cultivation in my country. At present, my country's melon cultivation area and output rank among the top in the world. Although melon is rich in resources, due to the strong seasonality of melon, harvesting The time is high temperature, and the fruit has high sugar content, high water content, strong physiological metabolism, and is easily infected by external pathogens and rots. Therefore, post-harvest diseases are relatively serious, which affects the economic benefits of melons. Strengthen the management of melons after harvesting to reduce economic losses, increase the storage cost of melons, and the control effect is limited. Therefore...
