Organic fertilizer for grapes

Abstract

The invention relates to the field of fertilizers, and in particular to an organic fertilizer for grapes, which is prepared from the following components in parts by weight: 20 to 25 parts of straw, 10 to 20 parts of sawdust, 10 to 12 parts of expanded perlite powder, 1 to 2 parts of nitrification inhibitor DMPP (3,4-dimethylpyrazole phosphate), 0.3 to 0.5 parts of tea saponin, 20 to 25 parts of rice straw, 20 to 25 parts of bean dregs, 20 to 30 parts of sawdust, 2 to 4 parts of zinc, 1 to 2 parts of iron, 0.2 to 1 part of copper, 0.2 to 1 part of magnesium, 0.1 to 0.5 parts of molybdenum and 2 to 3 parts of selenium. The organic fertilizer for grapes can overcome the defects of the prior art, a preparation method is simple, the fertilizer utilization rate of the prepared organic fertilizer for grapes is high, the dosage of conventional fertilizers is reduced, nitrogen activity is increased, the original nutrients in soil can be activated, and can be sufficiently absorbed and utilized by crops, the yield of crops is promoted to increase, the stress resistance of crops is increased, soil can be effectively improved, the organic fertilizer for grapes has high adaptability, is suitable for most of crops and soil, and the organic fertilizer for grapes has good compatibility, so that various fertilizers can be added.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to an organic fertilizer for grapes. 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...

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
