Liquid microorganism fertilizer for preventing and controlling fungal disease of cucumber and preparation method thereof

Abstract

The invention relates to a liquid microorganism fertilizer for preventing and controlling fungal disease of cucumber and a preparation method thereof. The liquid microorganism fertilizer is prepared from the following raw materials in parts by weight: 50 to 100 parts of streptomyces microflavus fermenting liquid, 60 to 80 parts of calcium carbonate, 10 to 40 parts of magnesium sulfate, 0.5 to 1 part of borax, 0.5 to 1 part of ferrous sulfate, 0.1 to 0.5 part of manganese sulfate, 0.001 to 0.01 part of zinc sulfate, 0.001 to 0.007 part of copper sulfate, and 0.001 to 0.005 part of ammonium molybdate. The preparation method comprises the following steps of performing ultrasonic-assisted enzymolysis to prepare an algae extracting liquid; preparing the prepared algae extracting liquid into a fermenting culture medium; under the certain conditions, culturing streptomyces microflavus; finally, compounding with the fermenting liquid and medium and trace elements, so as to prepare the liquid microorganism fertilizer. The liquid microorganism fertilizer has the advantages that the formula is scientific and reasonable, the complete and rich nutrients are contained, the growth and development requirements of the cucumber are met, the disease-resistant property of the cucumber is effectively improved, the fungal disease is prevented and controlled, the quality of the cucumber is improved, the output of the cucumber is increased, the safety in eating is improved, and the significant meaning is realized for promoting the development of green agriculture and production of green products.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to a liquid microbial fertilizer for preventing fungal diseases of cucumbers and a preparation method thereof. Background technique [0002] Cucumber, also known as king melon and pickled cucumber, is an annual climbing herb of Cucurbitaceae Cucumber, which originated in the tropical rainforest area at the southern foot of the Himalayas. Cucumber has the characteristics of high yield, rich nutrition, and good benefits. It is the most commonly cultivated melon vegetable in the world, and it is also one of the main vegetable crops with the largest cultivation area and the widest planting range in my country. [0003] Fungal diseases, such as powdery mildew and downy mildew, are common diseases in cucumber cultivation, and the production can be reduced by 30-50% in popular years. The methods of controlling cucumber fungal diseases at home and abroad mainly in...
