Organic charcoal and inorganic nutrient combined fertilizer

Abstract

The invention relates to the field of fertilizers and particularly relates to an organic charcoal and inorganic nutrient combined fertilizer. The fertilizer is prepared from the following ingredients in parts by weight: 20-25 parts of straws, 10-20 parts of sawdust, 10-12 parts of expansible perlite powder, 1-2 parts of nitrification inhibitor DMPP, 0.3-0.5 part of tea saponin, 15-20 parts of bamboos, 5-10 parts of quartz sand, 25-35 parts of kaolin, 15-20 parts of potassium sulfate, 6-9 parts of magnesium sulfate, 12-17 parts of monoammonium carbonate, 14-20 parts of ammonium dihydrogen phosphate and 14-18 parts of potassium humate. According to the organic charcoal and inorganic nutrient combined fertilizer, the disadvantages in the prior art can be overcome, the preparation method is simple, the prepared organic charcoal and inorganic nutrient combined fertilizer is high in utilization ratio, the investment of the conventional fertilizers is reduced, the nitrogen activity is improved, inherent nutrients in soil can be activated, crops can thoroughly absorb and utilize the nutrients, the increase of yield of the crops is promoted, the resistance of the crops is improved, and the soil can be effectively improved; due to high adaptability, the fertilizer is applicable to the majority of crops and soil; and due to good compatibility, various fertilizers can be added.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to organic carbon-bonded inorganic nutrient fertilizers. 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 s...

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
