Corn compound fertilizer

Abstract

The invention provides corn compound fertilizer. The corn compound fertilizer is prepared from base fertilizer and foliar fertilizer, wherein the base fertilizer is prepared from the following components in parts by mass: 80 to 100 parts of nitrogen, phosphorus and potassium compound fertilizer, 4 to 8 parts of medium and trace elements, 0.05 to 0.1 part of a rare-earth element, 60 to 100 parts of organic fertilizer, 10 to 15 parts of fluorspar powder and 12 to 20 parts of vermiculite; the nitrogen, phosphorus and potassium compound fertilizer contains 13.7 percent to 14.8 percent of nitrogen, 13.3 percent to 14.9 percent of phosphorus pentoxide and 13.2 percent to 14.8 percent of potassium oxide; the foliar fertilizer is prepared from the following components in parts by mass: 10 to 15 parts of urea, 6 to 8 parts of potassium sulfate, 1 to 1.6 parts of magnesium sulfate, 1.2 to 1.8 parts of zinc sulfate, 0.8 to 1 part of borax, 0.5 to 0.8 part of sodium selenite, 1.2 to 1.6 parts of ferrous sulfate, 30 to 40 parts of amino acid, 20 to 25 parts of humic acid, 0.5 to 1 part of glycerol, 1.2 to 1.8 parts of Chinese herbal medicine extract and 0.1 to 0.5 part of a plant regulator. The corn compound fertilizer provided by the invention has the advantages of comprehensive nutrients, slow-release growth, high utilization rate, good moisture-retention and fertilizer-retention capabilities, capability of improving physical properties of soil and high safety, and the quality and yield of corns are improved.

Description

technical field [0001] The invention relates to the field of crop fertilizers, in particular to a corn compound 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 a...

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.
