Organic fertilizer for vegetables and preparation method thereof

Abstract

The invention discloses a preparation method of an organic fertilizer for vegetables. The preparation method comprises the following steps: (1) mixing the following raw materials in parts by mass: 200 parts of a 5%-8% palm essence solution, 290 parts of a 5%-8% bamboo essence solution and 50 parts of bamboo stem cells, adding water and fermenting for 7-8 days; (2) mixing 100 parts of a 5%-8% moran or intsia essence solution with 30 parts of moran or intsia stem cells, adding water and fermenting for 7-9 days; (3) adding 180 parts of a 5%-8% eichhornia crassipes or duckweed essence solution and 30 parts of eichhornia crassipes or duckweed stem cells into a mixture obtained in the step (2), adding water and fermenting for 8-9 days; (4) adding 100 parts of 5%-8% akala essence and 20 parts of akala stem cells into a mixture obtained in the step (3), adding water and fermenting for 6-8 days; (5) performing rotary separation on a fermented product prepared in the step (4) through a centrifugal separator at the speed of 15,000 r / min for 2 hours, and fermenting at 30-35 DEG C for 6-8 days.

Description

Technical field: [0001] The invention belongs to the technical field of biological fertilizers, and in particular relates to an organic fertilizer for vegetables and a preparation method thereof. Background technique [0002] Fertilizers can be roughly divided into two categories, namely inorganic fertilizers and organic fertilizers. Among them, inorganic fertilizers are what we usually call chemical fertilizers. They have the advantages of high nutrient content, single element, fast fertilizer efficiency, cleanliness, and convenient application. However, long-term application of chemical fertilizers has brought many side effects while increasing production: [0003] 1) From the mining of chemical fertilizer raw materials to processing and production, some heavy metal elements or toxic substances will inevitably be brought into chemical fertilizers, which will be absorbed by crops after application, endangering human health; at the same time, whether it is acidic soil, sligh...

[0005] 3) Long-term application of chemical fertilizers will accelerate soil acidification

In practical application, it is found that the above-mentioned special fertilizer for green vegetables, like other commonly used fertilizers, needs to be directly applied to the soil. Only a small part of the fertilizer components can be absorbed by vegetables, and a large amount of fertilizer will be lost from the soil. The utilization rate is low, which increases the actual Production and use costs. Secondly, the above-mentioned special fertilizers for green vegetables have very limited effects on the control of vegetable surface diseases and insect pests, and still need to use a certain amount of pesticides for joint use. People still have high risks when eating vegetables. In addition, the green vegetables Special fertilizers use chemicals such as ammonium nitrate, manganese sulfate, and potassium iodide, which will still pollute and damage the soil. In vegetable production, this green vegetable special fertilizer still does not meet the needs of existing vegetable production
