Description

Technical Field

[0001] The invention relates to the technical field of straw processing, and in particular to a straw organically decomposed and fully nutritious biological fermentation integrated bag and a preparation method thereof. Background Art

[0002] In today's agricultural development pattern, it faces a series of severe challenges. For a long time, farmers have relied too much on chemical fertilizers and pesticides to pursue high crop yields, but this practice has brought serious consequences. Data show that the use of large amounts of chemical fertilizers has led to increasingly prominent land salinization problems in some areas, and the black soil layer has been lost at an alarming rate. For example, the black soil layer in some areas has decreased by 0.3 to 1 cm each year, and the structure of cultivated land has been damaged and is difficult to reverse. In order to maintain production, farmers have to double the use of chemical fertilizers and pesticides, falling into a vicious cycle.

[0003] In the Northeast, agricultural straw treatment has always been a problem. The straw has a high degree of lignification, and traditional treatment methods such as burning, baling, plowing or using it as biomass fuel have low utilization rates and poor results. Burning straw not only pollutes the environment but also wastes resources. Returning untreated straw to the field is likely to leave pathogens and insect eggs in the field, causing farmers to use a large amount of pesticides for pest control, disease prevention and weed control in the second year. Although herbicides and pesticides can control pests and diseases to a certain extent, their damage to the environment is even greater than that of straw burning. At the same time, they cannot fully utilize the nutrients in straw, resulting in a waste of resources and soil damage, which is not conducive to the long-term development of agriculture.

[0004] In order to protect the black soil, many methods have been tried in the past, such as spreading manure and organic manure for soil improvement, fermenting soybeans, amino acids, fruit enzymes, fish protein, and supplementing organic minerals, etc. However, these measures are not only costly, but also difficult to operate, and the promotion effect is minimal.

[0005] With the rapid development of agriculture, the treatment of crop straw has become an important environmental and resource utilization issue. The traditional method of straw burning causes environmental pollution, wastes organic resources, and the difficulty of returning straw to the field has brought challenges to the protection of black soil.
