Safe pollution-free organic fertilizer and preparation method thereof

Abstract

The invention discloses a safe and pollution-free organic fertilizer comprising the following raw materials by weight: 30-36 parts of flour, 20-28 parts of dead tree leaves, 18-26 parts of old vegetable leaves, 18-24 parts of wheat bran, 8-12 parts of urea, 6-8 parts of bentonite, 4-5 parts of silica, 5-6 parts of potassium phosphate, 5-6 parts of zeolite powder, 4-5 parts of food gum, 5-6 parts of EDTA chelated manganese, 3-4 parts of borax, 4-6 parts of ammonium molybdate, 4-5 parts of EM microbial inoculum, and a proper amount of rice washing water; the safe and pollution-free organic fertilizer uses the flour, the dead tree leaves, the old vegetable leaves and other organic materials as main raw materials, is added with a small amount of the potassium phosphate, the ammonium molybdate and other inorganic fertilizers, can fully complement soil nutrients by auxiliary effects of microbial fermentation, enables crops in different periods to acquire adequate nutrition, solves the problem of soil contamination of residues of high content of chemical fertilizers, has no pollution to the environment, is consistent with the strategy of sustainable development of agriculture, and realizes a win-win situation of benefit and environment, and the produced crops are healthy green crops.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a safe and pollution-free organic fertilizer and a preparation method thereof. Background technique [0002] China is a country with a large population. Agriculture plays an important role in people's daily life. Fertilizer is the most basic and important material input in agricultural production. The raw material price subsidy policy of chemical fertilizer production enterprises and the extension policy of chemical fertilizer The lack of fertilizer production has led to long-term losses, and relying on high-pollution, high-emission, high-waste, and low-efficiency production methods has added to the high production costs and gradually shrinking profits of chemical fertilizer companies. At the same time, the damage to the soil caused by traditional fertilizers, as well as the resulting products of poor quality, are being eliminated by the market. Based on the current healt...
