The invention adopts pyroligneous acid which is a product of plant pyrolysis gasification as a disease-resistant raw material, and simultaneously adds organic humic acid which promotes the growth of plant root systems, thereby developing a plant source disease-resistant growth promoter which resists wheat root rot and a high-efficiency application method thereof.
Description
Technical Field
The invention relates to a plant source disease-resistant growth promoter for resisting wheat root rot and application thereof, belonging to the field of plant growth regulators.
Background
Wheat root rot is a soil-borne disease caused by various pathogenic fungi, and fusarium and helminthosporium are common. These pathogenic bacteria can survive in soil for a long time and can occur during the whole growth period of wheat, and once the conditions are proper, the disease condition is easy to expand to cause spreading disasters. Generally, the yield of the wheat can be reduced by 20-30 percent, and can reach more than 50 percent in severe cases, so that the yield of the wheat is seriously influenced. The wheat root rot is not easy to be found in the early infection stage, and the optimal control period is missed when obvious symptoms appear on the overground part. In agricultural production, the main method for preventing and treating the diseases is chemical prevention and treatment. However, with the degradation of chemical pesticides, the generation of drug resistance by pathogenic bacteria, and the aggravation of the harm of chemical pesticides to the environment and human beings, the development and utilization of safe and effective control methods are urgent.
Biological pesticides are increasingly important in the prevention and treatment of plant diseases because of their advantages of being non-toxic, pollution-free and residue-free. For example, patent CN102057914A discloses a bactericidal composition containing metconazole and antibiotic compounds, and the antibiotics include validamycin, polyoxin, etc., and can be used for preventing and treating powdery mildew, downy mildew, gray mold, etc. Patent CN105284821A discloses a pesticide composition for preventing and treating wheat scab, which contains 1-150 parts by weight of validamycin and 1-20 parts by weight of metconazole per mu, and has obvious synergistic effect on wheat scab. The botanical pesticide is one of the first choice of green biological pesticide by virtue of the advantages of easy degradation and no pollution in natural environment. But the reports on the control of wheat root rot are less. At present, researches show that the pyroligneous liquor as a product of plant pyrolysis gasification has certain bacteriostatic activity on plant pathogenic bacteria, but the researches are only limited to the bacteriostatic research on the pathogenic bacteria per se, and reports on how the pyroligneous liquor is prepared into products which are marketed and applied in the field are few. For example, in the production process and production line of a wood vinegar composite preparation of patent application publication No. CN 110330994A, refined wood vinegar is emulsified and then mixed with auxiliary materials to prepare the wood vinegar composite preparation. The patent mainly describes a preparation method of the wood vinegar, and does not relate to the field application of the wood vinegar compound preparation.
