Carbonized straw-containing composite fertilizer

Abstract

The invention discloses a carbonized straw-containing composite fertilizer, and belongs to the technical field of fertilizers. The composite fertilizer comprises, by weight, 30-40 parts of carbonizedstraws, 20-30 parts of chicken manure, 10-20 parts of peanut shells, 5-10 parts of fermenting bacteria, 6-12 parts of calcium superphosphate and 3-9 parts of a humic acid fertilizer. The composite fertilizer can prevent soil hardening and effectively alleviate the problem of soil acidification, and biochar preserved in the soil for a long time can continuously increase the fertility of soil and retain water of the soil; the composite fertilizer can improve the permeability of the soil and regulate the temperature of the soil, so the propagation of pathogenic bacteria in the soil and invasion of plant roots are effectively inhibited, plant-borne diseases are reduced, and outbreak of various pests is prevented; and the composite fertilizer also has the advantages of increase of the survivalrate of crops, promotion of root growth, promotion of decomposition of organic matters in the soil into humus, great improvement of the fertilizing effect of the soil, promotion of growth and maturityof the crops, cost reduction, output increase and income increase.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a compound fertilizer containing carbonized straw. Background technique [0002] Compound fertilizer refers to chemical fertilizer containing two or more nutrient elements. Compound fertilizer has the advantages of high nutrient content, less auxiliary components and good physical properties. It is very important for balanced fertilization, improving fertilizer utilization rate, and promoting high and stable yield of crops. role. However, the proportion of compound fertilizer nutrients is fixed, which is difficult to meet the needs of various soils and various crops, and the movement rates of various nutrients in the soil are different, and the degrees of being retained and lost are different. Difficult to meet the technical requirements of fertilization. [0003] Straw is the remaining stalks and leaves of crops after harvesting. my country is a big country producing stra...

Problems solved by technology

At present, straw returning to the field is a more environmentally friendly method of straw reuse. It is relatively simple, time-saving and environmentally friendly to re-use straw into the field through mechanized returning, stacking and returning to the field, and returning to the belly; However, there are many types of straw in our country and the output is huge. The large amount of straw produced cannot be completely processed by returning the straw to the field alone. Moreover, if the straw is returned to the field without attention, not only the effect will not be obvious, but it will also have adverse effects on crops.
