Readily available organic compound fertilizer preparation method

Abstract

The invention discloses a readily available organic compound fertilizer preparation method, and belongs to the technical field of fertilizer. The preparation method comprises the following steps: a, preparation of organic fertilizer extracting solution: uniformly mixing 2-6 parts by weight of edible germ bran or straw powder, 2-7 parts by weight of livestock and poultry fresh faeces, 1-4 parts by weight of water, 0.05-0.4 part by weight of a nitrogen source, and 0.1-0.3 part by weight of an EM living bacteria microbial preparation, performing piling fermentation, performing filtering to obtain the filtrate, and performing evaporation and concentration to obtain an organic fertilizer extracting liquid; and b, compounding: adding fulvic acid and amino acids into the organic fertilizer extracting liquid to prepare the readily available organic compound fertilizer, wherein the organic fertilizer extracting liquid is 5.5-9.5 parts by weight, the fulvic acid is 0.5-2 parts by weight, and the amino acids are 0.5-2 parts by weight. The organic compound fertilizer provided by the invention has high content of effective components, has balanced, rapid and lasting fertilizer efficiency, has wide application and fewer application amounts, and is convenient for application. After application of the organic compound fertilizer, the crop yield is increased by 10-20%.

Description

technical field [0001] The invention relates to a quick-acting compound fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is the food for the growth of various plants. In addition to providing various nutrients necessary for plant growth, fertilizer can also improve the soil. Reasonable application of fertilizer is an important measure to increase crop yield. Traditional agricultural production mainly uses organic fertilizers, while modern agriculture uses more chemical fertilizers. In recent years, with the increasing demand for agricultural products, the amount of chemical fertilizers is increasing and there are more and more varieties. Compared with traditional organic fertilizers, they are easy to dissolve in water, easy to be absorbed and utilized, and have rapid effects. People are keen to use them. main factor. However, while the extensive use of chemical fertilizers has brought huge benefits to agriculture, it has also caused a s...

Problems solved by technology

However, while the extensive use of chemical fertilizers has brought huge benefits to agriculture, it has also caused a series of negative effects, such as soil compaction and barrenness due to the reduction of soil organic matter, and large-scale occurrence of diseases and insect pests due to micro-ecological imbalance.

With the emergence of bio-organic fertilizers and organic-inorganic compound fertilizers, the above-mentioned problems of single application of chemical fertilizers have been solved to a certain extent, but there are problems: the application of organic fertilizers without harmless treatment is likely to cause pests and diseases; Organic fertilizers such as dried chicken manure are solid, and their aqueous solutions are slag-containing liquids, which are difficult to apply and are not conducive to water-saving irrigation of economic crops; ordinary organic fertilizers are in the form of slag-containing solids, which are unevenly dispersed after being applied to the soil. Slow, especially in the germination period and spreading period of crops, it is difficult to combine with the plant root system to exert its due efficiency

At present, using industrial amino acid or mineral humic acid as quick-acting organic fertilizer is a more commonly used method, but there are also defects, that is, industrial amino acid has higher nitrogen-containing ions and lower pH value (powder pH value is about 4), This is not good for nitrogen avoiding crops such as watermelon, potato, sugar beet, tobacco, sugar cane, etc.

Mineral humic acid is prone to flocculation and precipitation in hard water and acidic soil, and loses its activity.
