Description

Technical Field

[0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer resistant to rice sheath blight. Background Art

[0002] As one of the most important food crops in the world, the yield and quality of rice are of vital importance to ensuring food security and meeting people's living needs. However, during the growth of rice, it is often threatened by various diseases, among which rice sheath blight is a common and serious disease.

[0003] Rice sheath blight is a fungal disease caused by Rhizoctonia solani, which has the characteristics of wide range of occurrence, rapid spread and severe damage. In the past agricultural production, the prevention and control of rice sheath blight mainly relied on chemical pesticides. However, the long-term and large-scale use of chemical pesticides not only easily leads to excessive pesticide residues, affecting the quality and safety of rice, but also may cause environmental pollution, destroy the ecological balance, and make pathogens gradually develop drug resistance, reducing the prevention and control effect.

[0004] Commonly used fertilizers often only focus on providing major nutrients such as nitrogen, phosphorus, and potassium, but ignore trace elements, which causes the soil to gradually become compacted, its fertility to decline, and its ability to retain water and fertilizer to weaken, which is not conducive to the sustained and healthy growth of rice. The application of microbial agents in agriculture has not received sufficient attention. The number and activity of beneficial microorganisms in the soil are insufficient, and they cannot effectively inhibit the reproduction and spread of pathogens, resulting in the rice's own weak resistance and susceptibility to diseases such as rice sheath blight. Summary of the invention
