Application method of photosynthetic bacteria culture solution in protected cultivation of melon

Abstract

The invention provides an application method of photosynthetic bacteria culture solution in protected cultivation of melon, which comprises the steps of: diluting the photosynthetic bacteria culture solution, uniformly soaking seeds with the solution, pouring root and spraying. The method can improve the abilities of melon cultured in protected field for resisting diseases, insects and adversity, enhance photosynthetic intensity, and promote healthy growth of the melon; increases content of soluble sugar, improves quality deterioration due to using fertilizers and pesticides during artificial cultivation; degrades residual pesticides and fertilizers, and other toxic and harmful substances in soil and plant, and guarantees security of agriculture products; and effectively increases the content of organic matter in soil and saves 1/3 of fertilizer use amount through carbon fixation and nitrogen fixation of melon itself. The method disclosed in the invention cannot only decrease the use amount of pesticides and fertilizers in protected cultivation of the melon, but also cannot cause residue of any harmful substance, and can satisfy production need of standard melon of green food and organic food.

Description

[0001] technical field [0002] The invention belongs to the technical field of melon cultivation, and in particular relates to an application method of a photosynthetic bacteria culture solution in the cultivation of melons in protected areas. Background technique [0003] Melon, also known as sweet melon or cantaloupe, has been cultivated in my country for more than 2,000 years. It originated in the tropical desert area of ​​Africa, and was later introduced to the Middle East, Central Asia, and India via Egypt, and then to my country. Melon is named for its sweet taste. It is also called muskmelon because of its delicate fragrance. The fruit is sweet and rich in sugar, starch, and a small amount of protein, minerals and other vitamins. Because of its characteristic fragrance and refreshing taste, it has become a favorite snack fruit in summer together with melon. At present, the national muskmelon cultivation area is about 400,000 hectares, with a total output of 12 milli...

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 high temperature and high humidity indoors can easily induce various diseases and insect pests of melons. 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 melons 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 photosynth
