Application method of photosynthetic bacteria culture solution in watermelon protected cultivation

Abstract

The invention provides an application method of a photosynthetic bacteria culture solution in watermelon protected cultivation. The application method comprises the following steps of: diluting the photosynthetic bacteria culture solution, and then, carrying out uniform seed soaking, root irrigation and spraying. According to the application method, the disease resistance, insect resistance and stress resistance of the watermelon in a sheltered ground can be improved, the photosynthetic intensity is enhanced, and the healthy growth of the watermelon is promoted; the soluble sugar content is increased, and the problem of quality decline arising from the use of chemical fertilizers and pesticides in artificial cultivation is solved; the residue of the pesticides and the chemical fertilizers and other toxic and hazardous substances in soil and plants are degraded, so that the safety of agricultural products is ensured; and the organic matter content in the soil can be effectively increased through the carbon and nitrogen fixation function of the watermelon, and therefore, the consumption of the chemical fertilizers is saved by 1 / 3. According to the application method, the application quantity of the pesticides and the chemical fertilizers in the watermelon protected cultivation is reduced, the residue of any hazardous substance cannot be caused, and therefore, the production demands of the watermelon on green and organic food standards can be met.

Description

[0001] Technical field [0002] The invention belongs to the technical field of watermelon cultivation, and particularly relates to an application method of a photosynthetic bacteria culture liquid in watermelon protected land cultivation. Background technique [0003] Watermelon, also known as water melon, cold melon, and summer melon, is the fruit of the Cucurbitaceae plant. It was introduced from the Western Regions in the Han Dynasty, so it is called "watermelon". The melon is round or oval in shape, with skin color ranging from dark green, green, white or green with snake stripes. The flesh is rich red, light red, yellow or white, sweet and juicy, refreshing and thirst-quenching. It is a good fruit in midsummer. Watermelon can be called the "King of Melons". In addition to being free of fat and cholesterol, watermelon contains a large amount of glucose, malic acid, fructose, protein amino acids, lycopene and rich vitamin C. It is a nutritious, pure and safe food. of f...

Problems solved by technology

First, due to the mild climate in the greenhouse, it is difficult to eliminate pests by relying on cold weather. In addition, the indoor high temperature and high humidity weather can easily induce various diseases and insect pests of watermelon. The conventional control method is to spray pesticides

With the increasing resistance of pests and diseases to conventional pesticides, the frequency of use of pesticides has increased, and the dosage of pesticides has increased, so that the food safety of watermelons on the market has become more and more problematic.

Second, due to the closed environment of the protection facility, the light and carbon dioxide in the facility greenhouse are seriously insufficient, and the photosynthesis of the crop is inhibited, which affects the growth and development of the watermelon plant, resulting in a double decrease in the yield and quality of the watermelon.

Third, in order to pursue one-sided economic benefits, growers only plant one or two crops such as watermelon in the greenhouse all the year round, and do not pay attention to crop rotation with other vegetable crops, which causes soil pathogens to increase year by year, and soil-borne diseases are aggravated every year, which seriously restricts Development of Watermelon Cultivation in Protected Areas

After retrieving the existing literature, there is no report on the application of photosynthetic bacteria culture solution in watermelon protected cultivation.
