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 photosynthesis of the crop is inhibited, which affects the growth and development of the melon plant, resulting in a double decrease in the yield and quality of the melon
Third, in order to pursue one-sided economic benefits, growers only plant one or two crops such as melons in the greenhouse all the year round, and do not pay attention to crop rotation with other vegetable crops, which increases the number of soil pathogens and soil-borne diseases every year, which seriously restricts the The development of cultivation of muskmelon in protected area
After retrieving the existing literature, there is no report on the application of photosynthetic bacteria culture solution in the cultivation of muskmelon protected areas.

Embodiment 1

[0033] Prepare photosynthetic bacteria culture medium according to the following components:

[0034] Sodium acetate 1000-2000mg CaCl2.2H2O 50-100 mg

[0035] MgSO4.7H2O 100-300 mg EDTA 10-30 mg

[0036] Yeast extract 500-1500 mg K2HPO4 500-1500 mg

[0037] (NH4)2SO4 1000-2000 mg KH2PO4 400-1000 mg

[0038] FeSO4. 7H2O 5-15mg trace element solution 1-5m1

[0039] Deionized water 1000-2000 ml pH 6 - 8

[0040] Wherein the trace element solution consists of:

[0041] H3BO3 200-300 mg Na2MoO4.2H2O 50-100 mg

[0042] CuSO4 2-10 mg MnSO4. 4H2O 150-250 mg

[0043] ZnSO4.7H2O 20-30 mg Deionized water 100-200 ml

[0044] Introduce 1 / 10 of the photosynthetic bacteria seed culture solution into the sterilized photosynthetic bacteria culture medium, anaerobic culture at a temperature of 15°C - 20°C; light intensity of 1800lux for 10 days, and the number of viable bacteria is 108— 1010 cfu / ml photosynthetic bacteria culture solution.

Embodiment 2

[0047] The preparation method of photosynthetic bacteria culture medium is the same as embodiment 1.

[0048] Introduce 1 / 5 of the photosynthetic bacteria seed culture solution into the sterilized photosynthetic bacteria culture medium, anaerobic culture for 8 days at a temperature of 15°C - 20°C; light intensity of 1200lux, and the number of viable bacteria is 108- 1010 cfu / ml photosynthetic bacteria culture solution.

[0049]In the middle and lower reaches of the Yangtze River, muskmelon seedlings are generally cultivated in protected areas in early and mid-January. Before sowing, in addition to ordinary high-temperature soaking, the seeds are soaked in photosynthetic bacteria culture solution diluted to 100 times the original volume for 60 minutes. After the seedlings are settled, the photosynthetic bacteria culture solution is diluted to 100 times of the original volume with water, and the roots are irrigated with the amount of 10 kg / mu. Dilute the photosynthetic bact...

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...
