Ricefield eel mucus-containing biofertilizer and preparation method thereof

Abstract

The invention provides a ricefield eel mucus-containing biofertilizer. The ricefield eel mucus-containing biofertilizer comprises fulvic acid potassium salt, peat, chlorogenic acid, ricefield eel mucus, vegetable leaves, cotton hulls, coriolus versicolor polysaccharide, secoiridoid, cellulose nitrate powder, fertile land radish plant, perlite, sweet potato meal fibers, rhodobacter azotoformans and halophilic methanogens. The invention also provides a preparation method of the ricefield eel mucus-containing biofertilizer. The ricefield eel mucus-containing biofertilizer is applied for sulfate-form lead-polluted saline-alkali soil, reduces soil sulfate content and soil pH and total salt content, improves soil water permeability and a water retaining capacity, improves soil gas permeability, increases content of water-stability soil granules with the size greater than 1mm in soil, increases soil nutrients and reduces soil lead content. The ricefield eel mucus-containing biofertilizer is used for Gaodan grass, improves a survival rate and a yield, prolongs a grass supply period and improves a Gaodan grass seed yield. The ricefield eel mucus-containing biofertilizer is used for Gaodan grass plantation, has the effect of resisting Gaodan grass aphids and reduces an aphid incidence rate.

Description

technical field [0001] The invention relates to a biological fertilizer containing eel mucus and a preparation method thereof, which belongs to the technical field of saline-alkali land improvement fertilizer. Background technique [0002] In recent years, due to the large amount of unreasonable application of chemical fertilizers and chemical pesticides, it not only consumes a lot of non-renewable resources, but also destroys the soil structure, pollutes the quality of agricultural products and the environment, and affects the health and survival of human beings. Therefore, from the perspective of the development trend of green agriculture and ecological agriculture advocated in modern agricultural production, pollution-free biological fertilizers that do not pollute the environment will definitely play an important role in future agricultural production. [0003] According to the current products and types of biological fertilizers, they can be divided into two categories:...

[0005] (2) Although its products also promote crop yield increase through the key role of microbial life activities contained in them, the key role of microbial life activities is not limited to improving the elemental nutrient supply level of plants, including the plant growth stimulants produced by them Stimulating effect on plants, promoting the absorption of nutrient elements by plants, or antagonizing the pathogenic effect of some pathogenic microorganisms, reducing crop pests and diseases and resulting in increased yields

[0007] (1) The effect of improving saline-alkali land is not good. Generally, it needs to be used in combination with soil amendments, which cannot simultaneously reduce the sulfate content in the soil, reduce the soil pH and the total salt content of the soil, and increase the soil moisture permeability and water retention capacity; improve The air permeability of the soil increases the content of water-stable aggregates larger than 1mm in the soil and increases the effect of soil nutrients;

[0008] (2) Cannot effectively reduce the lead content in the soil;

[0009] (3) It is used for the planting of pasture grass in saline-alkali land, the survival rate of pasture grass is low, the yield is low, and the grass supply period is short;

[0010] (4) It is used for the planting of forage grass in saline-alkali land, and the quality of forage grass is poor;

[0011] (4) It is used for the planting of forage grass in saline-alkali land, and has no insect resistance
