Plant fermentation extract for treating rice root rot and preparation method thereof

Abstract

The invention relates to the technical field of agricultural planting, and particularly discloses a plant fermentation extract for treating rice root rot and a preparation method thereof. The plant fermentation extract for treating rice root rot is prepared from following raw materials through fermenting, extracting and pulverizing, in parts by weight, 0.3 to 0.5 part of hirudin,20 to 25 parts ofcyrtomium fortunei; 30-32 parts of cortex lycii radicis, 2-3 parts of rhizoma phragmitis, 10-15 parts of bamboo leaf extract, 5-10 parts of pericarpium citri reticulatae, 1-3 parts of red ginseng, 15-20 parts of liquorice, 5-7 parts of pollen, 20-25 parts of radix bupleuri, 2-3 parts of shredded coconut stuffing, 3-5 parts of sea buckthorn, 0.1-0.2 part of echinopsis tubiflora flower, 0.1-0.15 part of zinc-enriched yeast, and 0.2 to 0.25 part of selenium yeast. The raw materials are easy to obtain, the preparation process is simple, soil flora is effectively improved, the number and activity of effective microorganisms in soil are increased, the soil enzyme content is increased, rice growth is facilitated, the yield is increased, and the plant fermentation extractis suitable for wide application and popularization.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of agricultural planting, in particular to a plant fermented extract for treating rice root rot and a preparation method thereof. [0003] (2) Background technology [0004] Rice root rot is mainly a root disease caused by fungi, which can cause rice leaves to shrink, roots to rot, and the plant’s ability to absorb water and nutrients to decrease, causing rice to fall easily and even die on a large scale; root rot is mainly caused by rot Caused by mold, fusarium, phytophthora and other hospital infections, the roots are immersed in water for a long time, and the oxygen content in the soil is reduced, which provides growth and reproduction conditions for fungal growth. [0005] In the prior art, pesticides such as metalapahymex or copper preparations are generally used to prevent and control the roots. However, the paddy field pesticides with water have limited penetration into the soil, and are eas...

Problems solved by technology

[0005] In the prior art, pesticides such as metalapahymex or copper preparations are generally used to prevent and control the roots. However, the paddy field pesticides with water have limited penetration into the soil, and are easy to lose with the paddy water, so it is difficult to control the root rot of rice. effective prevention of disease

[0006] Organic fertilizers are rich in protein, sugar, vitamins, minerals and other nutrients, which have the effect of providing fertilizer for rice for a long time. Improvement; however, organic fertilizers generally only provide nutrient supply and do not have the effect of preventing and controlling diseases and insect pests. If you want to add pesticide components to organic fertilizers to have antibacterial and insecticidal effects, the actual effect is the same as spraying pesticides, and it cannot solve the effect of pesticides on the soil. The problem of low penetration
