Organic fertilizer

Abstract

The invention relates to the field of fertilizers, and especially relates to an organic fertilizer. The organic fertilizer comprises the following components in parts by weight: 20-25 parts of straw, 10-20 parts of sawdust, 10-12 parts of expanded perlite powder, 1-2 parts of a nitration inhibitor DMPP, 0.3-0.5 parts of tea saponin, 50-80 parts of sheep manure, 20-35 parts of biogas residues, 10-15 parts of a green manure, 20-35 parts of fumigated soil, and 5-15 parts of cakes. The fertilizer overcomes the disadvantages of prior art, the preparation method is simple, and the organic fertilizer has the advantages of high utilization rate, reduced addition of common fertilizers, and improved nitrogen activity; the fertilizer can activate original nutrients in soil, ensure full absorption and utilization of crops, promote increase of crop yield, improve stress resistance of crops, and effectively improve soil. The fertilizer has good adaptability, and is suitable for most crops and soil with good compatibility, and various fertilizers can be added.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to an organic fertilizer. Background technique [0002] With the development of society and the improvement of agricultural production level, people's demand for fertilizers is also increasing. At present, the fertilizers used in production are mainly divided into two categories, one is gray manure, manure, green manure, etc. Mainly organic fertilizers, the other is chemical fertilizers, such as urea, ammonium phosphate, potassium oxide, etc. The main components of chemical fertilizers are inorganic compounds, which are synthesized by processing and decomposing primary raw materials in chemical fertilizer factories. For example, under the conditions of high temperature, high pressure and catalyst, hydrogen and nitrogen can be synthesized into ammonia, and ammonia can react with carbon dioxide to finally generate urea. As another example, ordinary calcium superphosphate can be obtained b...

AI Technical Summary

Problems solved by technology

Compared with organic fertilizers, chemical fertilizers contain higher fertilizer components. Due to the high content of active ingredients, they are small in size and convenient to transport and apply. However, the amount of one-time use should not be too much, otherwise it will cause loss of fertilizers and agricultural products.

Except for a few varieties, chemical fertilizers are mostly soluble in water and easily absorbed and utilized by plants. They are quick-acting fertilizers, but they are easy to deliquesce and form hard lumps, causing nutrient loss or inconvenience in application.

At the same time, some chemical fertilizers contain secondary components that can have adverse effects on soil and crops, and some chemical fertilizers such as ammonium sulfate used alone during the crop growth period can cause soil compaction

In addition, excessive application of chemical fertilizers may also lead to environmental pollution. The proportion of various nutrients is out of balance, and the soil begins to acidify and compact. The actual growth needs of crops; become an obstacle to the sustainable development of agriculture
