Abstract

The invention discloses a kind of straw composite organic fertilizer and a preparation method thereof. The straw composite organic fertilizer contains the following components: 200-300 parts by weight of straws, 20-30 parts by weight of soybean curb residue, 10-20 parts by weight of vinasse, 5-8 parts by weight of phosphorite powder, 6-10 parts by weight of humic acid, 2-4 parts by weight of trace elements, 4-6 parts by weight of a composite microbiological inoculant, 1-3 parts by weight of mint powder, 0.8-1.5 parts by weight of lycorine, 3-5 parts by weight of pericarpium granati powder, 1-2 parts by weight of sodium potassium tartrate and 4-7 parts by weight of activated carbon. The straw composite organic fertilizer disclosed by the invention has the advantages that the straw is adopted as a main raw material, the sodium potassium tartrate and activated carbon are added, heavy metal elements in soil can be removed, and the aim of purifying the soil is achieved, so that healthy growth of crops is guaranteed; and the mint powder, lycorine and pericarpium granati powder are added, so that the fertilizer has functions of expelling parasites and avoiding harm, the soil has disease-and-insect-resistant capability, and yield of the crops is increased.

Description

technical field

[0001] The invention relates to the field of organic fertilizers, in particular to a straw compound organic fertilizer and a preparation method thereof. Background technique

[0002] Returning straw directly to the field will cause problems such as imbalance of soil carbon and nitrogen ratio, accumulation of organic acids, difficulty in tillage and sowing, and poor growth of new seedlings. Every year during the crop harvest season, a large amount of straw is burned or discarded randomly, which has become a serious social and environmental problem. Straw composting is to turn crop straws into high-quality organic fertilizers. It not only solves agricultural waste straws, but also produces high-quality organic fertilizers, improves soil, improves soil fertility, and protects the ecological environment. It is of great significance to national food security and sustainable agricultural development. . However, many pests and bacteria will be produced during the ...

Examples

preparation example Construction

[0034] The present invention also provides a preparation method of straw compound organic fertilizer, comprising the following steps:

[0035] a) Mix the straw, bean curd residue, phosphate rock powder, trace elements, compound microbial agent, and appropriate amount of water evenly, seal and ferment at room temperature for 10 to 15 days, and turn the pile once every 3 to 4 days to obtain the fermented liquid;

[0036] b) Add mint powder, lycorine, pomegranate peel powder, distiller's grains, humic acid, potassium sodium tartrate, and activated carbon to the fermented liquid obtained in step a), stir evenly, dry, grind into powder, and obtain straw compound organic fertilizer .

[0037] The above-mentioned straw, bean curd residue, phosphate rock powder, trace elements, compound microbial agent, mint powder, lycorine, pomegranate peel powder, distiller's grains, humic acid, potassium sodium tartrate, and activated carbon are all the same as above, and will not be repeated here...
