Description

technical field

[0001] The invention relates to a fertilizer and a preparation method thereof, in particular to a special bio-organic fertilizer for sweet sorghum suitable for saline-alkali land and a preparation method thereof. Background technique

[0002] Sorghum is the most salt-tolerant crop among grain crops such as wheat and corn, and it is also the most suitable crop for the development of saline-alkali land. The poor salt tolerance of sweet sorghum is mainly manifested in the germination and seedling stage. First, the seeds are damaged by the salinity of the surface soil after sowing, and the seedlings cannot germinate, resulting in rotten buds; Seedling. But as long as the seedlings are kept, as the plants grow, the root system will gradually develop, and the salt tolerance of the plants will increase. In addition, the middle and late stages of growth are in the rainy season, the soil salt content will decrease, and the salt damage will be alleviated. Overcoming ...
