Abstract

The invention discloses a composite fertilizer comprising chitin, humic acid, and middle and trace elements. The fertilizer is prepared from the raw materials of 1 part of chitin, 0.5 parts of chitosanoligosaccharide, 250 parts of urea, 450 parts of monoammonium phosphate, 100 parts of potassium chloride, 50 parts of sodium humate, 100 parts of bentonite, 10 parts of calcium-magnesium-phosphate fertilizer, 6 parts of zinc sulfate, 6 parts of borax, 4 parts of ammonium molybdate, 4 parts of manganese sulfate, 10 parts of ferrous sulfate, and 10 parts of magnesium sulfate. The fertilizer provided by the invention has the advantages that: the fertilizer has rich nutrient element; chitin, humic acid, and middle and trace elements are blended, such that the utilization rate of middle and trace elements is improved; and functions of cropping resistance, nematode control, crop disease reduction, soil improvement, crop quality improvement, high crop yield improvement are provided.

Description

technical field [0001] The invention relates to an agricultural fertilizer, in particular to a compound fertilizer containing chitin, humic acid and trace elements. Background technique [0002] At present, there are a lot of compound fertilizers on the market, but they have few nutrient elements and mainly contain three elements of N, P and K. The nutrient utilization rate is low, and the soil environment will deteriorate after long-term use, which is not conducive to the continuous increase of crop production. Occurrence, crops can not achieve increased yield, can not improve crop quality, so that farmers reduce income. Contents of the invention [0003] The object of the present invention is to provide a slow-release, quick-acting combination, anti-heavy cropping, inhibit nematode growth, improve crop quality and soil structure, proliferate beneficial bacteria, promote seedlings and roots, enhance crop resistance, increase production and income, and have obvious effects...
