Cultivation method for anti-cracking watermelons

Abstract

The invention provides a cultivation method for anti-cracking watermelons, which comprises the following steps: spraying a nutrient solution in a seedling stage, and spraying an anti-cracking agent for four times from a watermelon fruit setting stage, so that the cracking phenomenon after the watermelons are ripe is reduced, the storage time of the watermelons is prolonged, and certain economic benefits are brought to watermelon farmers. Soybean protein is modified, the water binding capacity is enhanced, after the anti-cracking agent forms a film on the surface of the watermelon, cells on the surface of the watermelon rind can be in a moisture balance state and are tightly arranged, the compressive strength is increased, and the toughness of the watermelon rind is improved; the modified soybean protein and the polyglycerol fatty acid ester are blended and interacted to enhance the network structure of the film, and after the anti-cracking agent is sprayed to watermelons, a layer of film with good elasticity, rain wash resistance, good stability, good air permeability and good light transmission is formed on the surface of watermelon rind, and normal growth of the watermelons is not affected at all. By means of the cultivation method for the anti-cracking watermelons, the fruit cracking rate of the watermelons per mu is lower than 1%, and meanwhile the yield can be increased by 10-12%.

Description

technical field [0001] The invention belongs to the technical field of watermelon cultivation, and in particular relates to a method for cultivating anti-cracking watermelon. Background technique [0002] Watermelon is a common fruit in summer. It is refreshing and sweet, and can reduce heat and heat. The thin-skinned and juicy watermelon is especially popular among people. However, thin-skinned watermelons are prone to skin cracking. This is because nitrogen fertilizers are essential for the growth of watermelons. The application of nitrogen fertilizers can greatly increase the growth rate of watermelons, but the growth rate of the flesh is much faster than that of the skin. During the ripening period, the melon skin ages and hardens, and the toughness decreases. In this way, if the watermelon enters the ripening period, if it encounters continuous rainy weather or is stimulated by the outside world, the melon skin is easy to crack, which not only affects the appearance, bu...

However, this method is only applicable to some small fruits such as lychee and longan. For watermelon, a fruit with high water content, exposure to the sun after continuous rainy days can easily cause the watermelon to crack.

This is because, in cloudy and rainy days, low light and low temperature tend to cork the melon rind, thereby reducing the toughness of the melon rind. In the following sunny days, the growth rate of watermelon is accelerated, and it is easy to crack
