A kind of anti-cracking agent for watermelon and application thereof

Abstract

The invention discloses a watermelon anticracking agent. The watermelon anticracking agent is prepared from 5-20 parts by weight of chitosan oligosaccharide, 10-30 parts by weight of polyvinyl alcohol, 10-30 parts by weight of methyl cellulose, 0.5-5 parts by weight of brassinolide, 20-50 parts by weight of higher fatty acid, 5-20 parts by weight of magnesium sulfate, 5-20 parts by weight of calcium nitrate, 1-5 parts by weight of borax, 1-5 parts by weight of organosilicon, 0.5-2 parts by weight of ammonium molybdate and 0.5-2 parts by weight of rare earth fertilizer. The watermelon anticracking agent can effectively prevent watermelon cracking and can be used as a yield increasing agent for muskmelons, Chinese dates, cherries, tomatoes and grapes. In use, the watermelon anticracking agent is diluted through water by 500-1000 times and then is sprayed to the whole plant 3-5 times in the whole growth period. The watermelon anticracking agent has excellent film formation and diffusivity, has good effects of temperature increasing, moisture retention, disease resistance, yield increasing and quality improvement and can effectively prevent and control watermelon cracking phenomenon.

Description

technical field [0001] The invention relates to a watermelon anti-cracking agent and its application. Background technique [0002] Watermelon is one of the most important fruits in summer. It is sweet and refreshing, can quench heat and thirst, and has the functions of diuresis, laxative, detoxification, and purging fire. Now it has become a fresh fruit cultivated in four seasons and enjoyed all year round. However, during the cultivation process, due to unsuitable temperature, improper use of fertilizer, water imbalance, poor management, hormones, varieties and other reasons, different degrees of cracking of melons often occur, especially watermelon cultivation in early spring greenhouses is more likely to cause cracking of melons, mild 5~10% of output reduction, serious reduction of 50~60% of output, even no harvest, brought very large economic loss to melon growers. [0003] Cracked melons are naturally split into two or more petals from the navel of the watermelon duri...

Problems solved by technology

3. The watermelon enters the harvesting period, which is also the time when the melon skin is the thinnest. For many watermelon varieties, it is easy to cause cracking during this period.

[0004] In the prior art, in order to prevent the watermelon from cracking, melon growers often use spraying to strengthen the melon pedicle spirit to prevent the occurrence of cracking melon by maintaining the nutritional balance of the watermelon itself, but the effect is not obvious, and the control effect is very small, which cannot meet the normal watermelon.
