Organic fertilizer and preparation method therefor

Abstract

The invention discloses an organic fertilizer and a preparation method therefor. The organic fertilizer is prepared from main materials and additives. The main materials comprise, by weight, 150-240 parts of cottonseed meal, 200-300 parts of bean vines, 100-200 parts of water hyacinth, 300-400 parts of decomposed soil, 120-160 parts of chicken manure, 80-130 parts of rabbit dung and 70-120 parts of peanut shells. The auxiliary additives comprise, by weight, 50-80 parts of amino acid, 80-110 parts of humic acid, 60-100 parts of plant activated selenium, 50-90 parts of abamectin, 30-50 parts of bacilli, 60-100 parts of chitosan and 70-130 parts of zymophyte. The fertilizer efficiency of the organic fertilizer lasts long, the fertility is large, the organic fertilizer is green and environmentally friendly, can promote pitaya growth and can prolong the fruiting stage of pitaya, and thus the pitaya output is raised greatly.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof. Background technique [0002] At present, my country's agriculture generally uses a single form of chemical fertilizers, supplemented by organic fertilizers and biological fertilizers. Due to the long-term repeated excessive application of chemical fertilizers in agriculture, the soil is compacted, the organic matter is reduced, and a large number of microorganisms die. In order to achieve the production target, farmers have to increase the input of chemical fertilizers every year. In Jilin and other places alone, the fertilization per hectare is as high as more than one ton of fertilizer. The more chemical fertilizers are applied, the more compact the soil and the more the microorganisms will die. The lower the organic matter, the weaker the soil's ability to retain water and fertilizer, and the worse the soil aggregate structure. The lower the soil's three permeability...

The existing soil-improving fertilizers can only see the impact of fertilizers on crops, and cannot effectively improve the soil

Most of the soil is compacted due to the application of chemical fertilizers, and the poor soil is not effectively improved due to unreasonable fertilization, resulting in no harvest or poor harvest; especially saline-alkali land occupies a considerable land area in our country and even countries in the world. It is too heavy to be cultivated, and some have invested a lot of money to improve, to discharge alkali and suppress salt, but with little effect
