Problems solved by technology

When we planted, these heavy metals seriously affected the growth of crops, and the growth rate of crops and fruit quality were seriously hindered
Moreover, during the growth process of crops, pesticides will be used to kill insects and sterilize, but the existing pesticides are easy to remain, a large amount of pesticides seriously pollute the ecology, and the food with pesticide residues seriously threatens human health
Nowadays, the use of many chemical fertilizers can easily cause soil compaction, resulting in low crop yields

Abstract

The invention discloses an organic fertilizer additive for reducing a heavy metal pollution source, which comprises the following components in parts by weight: leftovers, a Chinese herbal medicine, selenomethionine, boric acid, oil bran, humic acid and a water retention agent, wherein the leftovers comprises chicken manure, rapeseed meal, a peanut shell and pennisetum alopecuroides. The organic fertilizer additive for reducing the heavy metal pollution source can reduce heavy metal and increase a yield of crop. The invention further discloses a preparation method of the organic fertilizer additive for reducing the heavy metal pollution source.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers and relates to an organic fertilizer additive for reducing heavy metal pollution sources. Background technique [0002] Existing soil is getting more and more polluted, and the soil contains more or less heavy metals. When we planted, these heavy metals seriously affected the growth of crops, and the growth rate of crops and fruit quality were seriously hindered. Moreover, during the growth process of crops, pesticides need to be applied to kill insects and sterilize, but the existing pesticides are easy to remain, a large amount of pesticides seriously pollute the ecology, and the food with pesticide residues seriously threatens human health. The use of many chemical fertilizers can easily cause soil compaction, resulting in low crop yields. Therefore, the country is also vigorously advocating the reduction of the use of inorganic fertilizers, but nitrogen, phosphorus and potassium are e...
