Biological carbon-based ecological fertilizer

Abstract

The invention relates to a biological carbon-based ecological fertilizer. The biological carbon-based ecological fertilizer is prepared from, by weight, 30 to 40 parts of biological carbon, 10 to 30 parts of humic acid, 10 to 20 parts of urea, 5 to 15 parts of ammonium dihydrogen phosphate, 5 to 15 parts of potassium sulphate, 1 to 5 parts of pyroligneous liquid, and 0.5 to 2 parts of trace element. The biological carbon-based ecological fertilizer is capable of increasing soil organic matter content and soil cation exchange capacity effectively, activating soil, promoting formation of soil aggregate structures, preventing and treating soil salinization, avoiding successive cropping obstacles, improving nitrogen fixation and phosphate solubilizing functions, releasing phosphorus, potassium, and trace element immobilized in soil, improving soil fertilizer, water, and soil moisture conservation capacity, reducing fertilizer application amount, reducing grain pollution caused by soil with excess heavy metal, stimulating crop growth, and improving agricultural product quality obviously.

Description

technical field [0001] The invention relates to the technical field of carbon-based ecological fertilizers, in particular to a biochar-based ecological fertilizer. Background technique [0002] China is a big agricultural country. With the improvement of farmers' living standards, farmers pay more and more attention to the use of organic fertilizers. Since the traditional agriculture in the past few decades has used inorganic or inorganic compound fertilizers, which only pursue high yields and do not pay attention to the protection of the soil ecological environment, the use of such fertilizers for a long time will directly lead to the reduction of the quality of agricultural and sideline products. It has caused soil compaction, decreased fertility, poor tillability, decreased organic matter content, destroyed the adverse effects of soil ecological balance, and caused serious pollution to the soil. On the one hand, the quality of cultivated land is continuously declining du...

Since the traditional agriculture in the past few decades has used inorganic or inorganic compound fertilizers, which only pursue high yields and do not pay attention to the protection of the soil ecological environment, the use of such fertilizers for a long time will directly lead to the reduction of the quality of agricultural and sideline products. It has caused soil compaction, decreased fertility, poor tillability, decreased organic matter content, destroyed the adverse effects of soil ecological balance, and caused serious pollution to the soil.

On the one hand, the quality of cultivated land is continuously declining due to the lack of scientific and reasonable material inputs; on the other hand, a large number of agricultural, forestry, and industrial biomass resources are being abandoned
