Organic liquid fertilizer for promoting rhizome increase and methods for preparing and applying organic liquid fertilizer

Abstract

The invention relates to an organic liquid fertilizer for promoting a rhizome increase and methods for preparing and applying the organic liquid fertilizer. The organic liquid fertilizer is characterized by comprising the following raw materials by weight: 0.005-0.15% of A-type fungus, 0.5-5% of brown sugar molasses, 0.15-1.5% of bact-peptone, 0.005-0.15% of B-type fungus, 0.25-0.5% of fish milt, 0.15-1.5% of animal giblets containing a liver and / or a gallbladder, 0.05-1% of seaweeds, and the balance of water; the A-type fungus comprises any one or more of azotobacter, nitrobacteria, phosphorus-solubilizing bacteria, saccharomycetes, lactic acid bacteria, photosynthetic bacteria, actinomyces, and growth bacteria; the organic liquid fertilizer has the benefits that the yield can be increased by using the liquid fertilizer with low concentration. Through spraying and fertilizing of the organic liquid fertilizer, the height of plants can be lowered, and the yield can be increased; moreover, the fertilizing method of the organic liquid fertilizer can directly collocated with either spraying pesticide or sprinkling irrigation and the convenience is brought for application. The organic liquid fertilizer contains a great amount of the beneficial microbes and the metabolites of the microbes after sprayed, so that the disease can be prevented and the yield can be increased by 10-25% or higher.

Description

technical field [0001] The invention relates to an organic liquid fertilizer with organic composite beneficial microorganisms, in particular to an organic liquid fertilizer for promoting rhizome enlargement, a preparation method and a use method. Background technique [0002] Due to the food crisis in the world, in addition to breeding for bulk grain research, a large amount of chemical fertilizers are used in order to increase production. However, excessive application of chemical fertilizers for a long time will not only waste a lot of scarce resources, but also damage the soil structure, cause soil compaction, and salinization. , causing a variety of environmental problems, such as water eutrophication, water pollution and so on. Moreover, the nutrient elements that chemical fertilizers can provide to crop growth have certain limitations, which are prone to problems such as uneven growth of plants and reduced ability to resist diseases and insect pests. The uneven growth...

Problems solved by technology

[0002] Due to the food crisis in the world, in addition to breeding for bulk grain research, a large amount of chemical fertilizers are used in order to increase production. However, excessive application of chemical fertilizers for a long time will not only waste a lot of scarce resources, but also damage the soil structure, cause soil compaction, and salinization. , causing various environmental problems, such as water eutrophication, water pollution, etc.

Moreover, the nutrient elements that chemical fertilizers can provide for crop growth have certain limitations, which are prone to problems such as uneven growth of plants and decreased ability to resist diseases and insect pests.

The uneven growth of plants will further increase the amount of chemical fertilizers and fertilizers; the decline in plant resistance to diseases and insect pests will lead to an increase in the amount of pesticides and the frequency of application

As a result, a vicious circle is formed, which not only seriously affects the yield of rhizome crops, but also affects the quality and safety of rhizomes, causing problems such as excessively high pesticide residues in root crops, and poor economic benefits.

A large number of microorganisms in the soil have decreased, leading to the occurrence of diseases, and the yield has dropped to a critical point every year. For example, the normal yield of potatoes is 600-800 catties / mu (depending on the variety). Leaf fertilizers have been added to increase production during medicine, but the increase in production is limited, and the use of chemical fertilizers has the problem of nitrous acid residues.
