Description

Technical Field

[0001] The present invention relates to the field of agriculture, and specifically to an organic soil activation aid and its preparation method and application. Background Art

[0002] Soil is the foundation of the terrestrial ecosystem and is crucial for plant growth, hydrological cycle and climate regulation. However, the overuse of chemical fertilizers and pesticides in agricultural activities has led to a decline in soil quality, resulting in problems such as acidification, salinization and hardening. In addition, soil pollution, such as the accumulation of heavy metals and organic pollutants, directly affects food security and human health. To improve soil quality, organic soil activation aids and soil remediation technologies have been proposed. Organic soil activation aids can improve soil structure, increase fertility, reduce the use of chemical fertilizers and promote the development of sustainable agriculture. Soil remediation technologies include bioremediation, chemical remediation and physical remediation, each with its own advantages and disadvantages, and need to be selected according to specific circumstances.

[0003] An organic soil activation aid is an organic substance used to improve soil structure and enhance soil fertility. Compared with chemical fertilizers, it is more environmentally friendly. Such aids have functions such as moistening the soil, reducing salt and dissolving phosphorus, improving the utilization rate of phosphate fertilizer, reducing salinity and reducing soil-borne diseases, and are particularly suitable for saline-alkali land or areas with low utilization efficiency of phosphate fertilizer.

[0004] Existing organic soil activation aids are only effective for specific soil types or crops, lack universality, and are affected by multiple factors such as soil type, climate conditions and crop varieties, resulting in unstable effects and difficult to ensure consistent yield increase effects, and there is room for improvement.
