Problems solved by technology

Organic farming requires no use of any synthetic substances and has strict restrictions on the application of manure
However, no fertilization will greatly reduce crop yields and make organic agriculture unsustainable; therefore, the development of organic fertilizers for organic agriculture will have a broad prospect

Embodiment 1

[0024] Crush 50 parts of weathered coal and 40 parts of castor bean shells to 60 mesh and 100 mesh respectively, mix with 10 parts of 100 mesh phosphate rock powder, add 30 parts of active yeast liquid, and ferment at 40°C to 50°C for 5 days, then Dried until the water content is less than 20%, forming off-white loose material, measured and bagged to become the finished product. The obtained soil conditioner contains N5.0%, P 2 o 5 3.0%, K 2 O2.0%.

Embodiment 2

[0026] Crush 70 parts of weathered coal and 20 parts of castor bean shells to 60 mesh and 100 mesh respectively, mix with 10 parts of 100 mesh phosphate rock powder, add 20 parts of active yeast liquid, and ferment at 60°C to 70°C for 3 days, then Dried until the water content is less than 20%, forming off-white loose material, measured and bagged to become the finished product. The obtained soil conditioner contains N3.0%, P 2 o 5 2.2%, K 2 O1.3%.

Embodiment 3

[0028] Crush 60 parts of weathered coal and 35 parts of castor bean shells to 60 mesh and 100 mesh respectively, mix with 5 parts of 100 mesh phosphate rock powder, add 40 parts of active yeast liquid, and ferment at 50°C to 60°C for 4 days, then Dried until the water content is less than 20%, forming off-white loose material, measured and bagged to become the finished product. The resulting soil conditioner contains 4.5% N, P 2 o 5 2.5%, K 2 O2.0%.

Abstract

An organic soil ameliorant and its production are disclosed. The process is carried out by mixing leonardite 50~70wt% and castor shell 20~45wt% with ground phosphate rock 5~10wt% and fermenting. It is simple and costs low. It can be used for the improvement of saline-alkali soil and low-yield filed.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a green and environment-friendly organic soil improver and a preparation method thereof. Background technique [0002] The area of ​​medium and low-yield fields in my country accounts for about 2 / 3 of the total cultivated land; land desertification, salinization and desertification are the main manifestations of medium-low-yield fields. Improving or restoring desertified and salinized land is an important means to improve the local ecological environment and increase farmers' income. The main reason for the formation of desertification and inland salinization land is the lack of water source or water retention, so it is unrealistic to use water for irrigation or washing salt for most desertification and salinization areas. Long-term practice has shown that the application of organic fertilizers and plant straws is an important means to improve the productivity of desertified and salinize...
