Organic fertilizer and preparation method therefor

Abstract

The invention discloses an organic fertilizer and a preparation method therefor. The organic fertilizer is characterized in that the organic fertilizer is prepared from main materials and auxiliary additives; the main materials comprise, by weight, 80-160 parts of activated sludge, 40-70 parts of powdered rock phosphate, 60-120 parts of gypsum, 100-200 parts of corn stalks, , 30-60 parts of brown sugar, 70-130 parts of husks, 110-230 parts of pine needles, 90-180 parts of vegetable stems and 120-230 parts of decomposed soil. The auxiliary additives comprise, by weight, 20-40 parts of polysaccharide polypeptide, 25-50 parts of alginic acid, 25-35 parts of avermectin, 20-40 parts of trace elements, 15-32 parts of fruit retention agents and 10-20 parts of rooting agents. The fertilizer efficiency of the organic fertilizer lasts long, the fertility is large, the organic fertilizer is green and environmentally friendly, can promote fruit growth and can prolong the fruiting stage of fruit, and thus the fruit 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
