Problems solved by technology

At present, chemical fertilizers on the market can meet the growth needs of corn 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 corn
Although pure organic fertilizer is rich in organic matter, it releases nutrients slowly, absorbs slowly by corn, and has low fertilizer efficiency. The effective balance between various effective nutrients cannot be achieved.
[0004] At present, corn pests an

preparation example Construction

[0035] Specifically, the preparation method of the base fertilizer comprises the steps of:

[0036] Drying nitrogen, phosphorus and potassium compound fertilizer, medium and trace elements, fluorspar powder, and vermiculite, uniformly mixing, pulverizing, and passing through a 80-100 mesh sieve to obtain spare material 1;

[0037] After pulverizing the organic fertilizer, pass it through a 80-100 mesh sieve to obtain the spare material 2;

[0038] 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.

[0039] 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 amino acids, 22-25 parts of humic acid, 0.6-0.8 par...

Abstract

The invention provides a corn combined fertilizer. The corn combined fertilizer comprises a base fertilizer and a foliage fertilizer in the mass ratio of 1:(0.15-0.25). The base fertilizer is prepared from, by mass, 80-100 parts of nitrogen-phosphorus-potassium compound fertilizer, 4-8 parts of medium trace elements, 0.05-0.1 part of rare earth elements, 60-100 parts of organic fertilizer, 10-15 parts of fluorite 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 sulfate, 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 herbal medicine extracts and 0.1-0.5 part of plant regulator. According to the corn combined fertilizer, multiple elements are compounded, organic substances and inorganic substances are combined, various nutrients work together, nutrients are comprehensive, slow-release growth is achieved, water and fertilizer retention ability is good, safety is high, and the quality and the yield of corn are improved and increased respectively.

Description

technical field [0001] The invention relates to the field of crop fertilizers, in particular to a corn set fertilizer. Background technique [0002] Corn is the main food crop in our country. It is known as a longevity food. It is rich in protein, fat, vitamins, trace elements, cellulose and polysaccharides. It has become a popular health food and often appears on people's tables. It has great potential to develop food with high nutrition and high biological function, and corn is also the raw material of feed and future bioenergy. [0003] Corn is a high-yield crop that needs more fertilizer. During the growth and development process, it needs to absorb a lot of nutrients, among which nitrogen, phosphorus and potassium are the most required, followed by calcium, magnesium, sulfur, boron, zinc, manganese and other elements. At present, chemical fertilizers on the market can meet the growth needs of corn in a short period of time, but long-term use will damage the soil aggreg...
