Problems solved by technology

At present, chemical fertilizers on the market can meet the growth needs of rice in a short period of time, but long-term use will damage the soil aggregate structure, easily cause soil compaction, and soil hardening, thus affecting the growth of rice
Although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, absorbs slowly in rice, and has low fertilizer efficiency. Effective balance of various effective nutrients cannot be achieved.
[0004] At present, rice pests and diseases are mainly controlled by using chemical reagents and toxic pesticides, mixed and stirred, applied to the soil or crops, and used year after year, resulting in drug resistance of diseases and insect pests, soil compaction, and pollution of water sources, soil and crops. The quality of agricultural products has declined, and pesticide residues exceeding the standard have seriously affected people's physical and mental health and the competitiveness of my country's rice in the international market

preparation example Construction

[0040] Specifically, the preparation method of the base fertilizer comprises the steps of:

[0041] After drying nitrogen, phosphorus and potassium compound fertilizer, medium and trace elements, rare earth elements, quicklime, fluorspar powder, and vermiculite, they are uniformly mixed, crushed, and passed through a 80-100 mesh sieve to obtain a spare material 1;

[0042] After crushing the fermented organic fertilizer, pass it through a 80-100 mesh sieve to obtain the spare material 2;

[0043] The standby material 1 and the standby material 2 are uniformly mixed in a mixer, heated to 60-70° C., dried and sent to a granulator for granulation to obtain a base fertilizer.

[0044] Further, the foliage fertilizer includes the following components by mass: 12-14 parts of urea, 6-8 parts of potassium sulfate, 1.2-1.6 parts of magnesium sulfate, 1.4-1.6 parts of zinc sulfate, 0.8-1 part of borax, 0.6-0.8 parts of sodium selenite, 1.4-1.5 parts of ferrous sulfate, 32-36 parts of a...

Abstract

A fertilizer special for rice comprises a base fertilizer and a foliage fertilizer. The base fertilizer is prepared from, by mass, 80-100 parts of a nitrogen, phosphorus and potassium compound fertilizer, 4-8 parts of medium and trace elements, 0.05-0.1 part of rare earth elements, 5-10 parts of quick lime, 60-100 parts of an organic fertilizer, 10-15 parts of fluorspar powder and 12-20 parts of vermiculite; the foliage fertilizer is prepared from, by mass, 10-15 parts of urea, 6-8 parts of potassium sulphate, 1-1.6 parts of magnesium sulfate, 1.2-1.8 parts of zinc sulfate, 0.8-1 part of borax, 0.5-0.8 part of sodium selenite, 1.2-1.6 parts of ferrous sulfate, 30-40 parts of amino acid, 20-25 parts of humic acid, 0.5-1 part of glycerol, 1.2-1.8 parts of Chinese herb extracts and 0.1-0.5 part of a plant regulator. According to the fertilizer special for the rice, multiple elements are compounded, the organic elements and the inorganic elements are combined, various nutritional ingredients achieve the synergistic effect, the nutrition is complete, slow-release growth is achieved, the utilization rate is high, the water retaining capacity and the fertilizer retaining capacity are good, the physical characteristics of soil are improved, the Chinese herbs achieve pest killing and fungus resisting, the safety is high, the rice quality is improved, and the rice yield is increased.

Description

technical field [0001] The invention relates to the field of crop fertilizers, in particular to a special fertilizer for rice. Background technique [0002] Rice is an important food crop in my country. Its sown area and total output rank second only to rice, and it occupies an important position in agricultural production. In recent years, a large number of blind fertilization has caused waste of fertilizers, and the application ratio of nitrogen, phosphorus, and potassium has been seriously out of balance, resulting in the accumulation of soil salt, causing environmental pollution, and excess nutrients in the soil often enter water bodies and The atmosphere not only leads to the decline of fertilizer utilization rate, but also leads to groundwater pollution and eutrophication of rivers and lakes. The cost of agricultural investment has increased, and the benefits of increasing agricultural production have been slow. [0003] The absorption of nutrients by rice has its ow...
