Control method for radically treating amorphophallus konjac soft rot based on bacillus subtilis

Abstract

The invention discloses a control method for radically treating amorphophallus konjac soft rot based on bacillus subtilis in the technical field of amorphophallus konjac soft rot control. Amorphophallus konjac seeds are strictly selected, airing is performed to reduce the adhesion amount of pathogenic bacteria, planting soil is sterilized to prevent the soil from carrying pathogenic bacteria and kill the existing pathogenic bacteria in the soil, meanwhile, a biological bactericide is applied to the bottom of the soil, the biological bactericide is sprayed to irrigate roots after leaves of the amorphophallus konjac are expanded, disease plants of the amorphophallus konjac in the growing period are subjected to first-aid treatment, the morbidity and death rate are reduced, the plant protection policy of 'prevention first and comprehensive prevention and treatment' and the principle that pesticides are applied before diseases are followed, and main component bacillus subtilis particles can realize sterilization intangibly after entering the soil by utilizing the advantage of integration of space occupation, antagonism, bacteriolysis and growth promotion, sterilization, can block and repel soft rot fungi from infecting seedballs, and are free of residues in soil, ecological, environment-friendly, free of toxicity, sustainable to use and safe to people and livestock.

Description

technical field [0001] The invention relates to the technical field of control of konjac soft rot, in particular to a control method for radically curing konjac soft rot based on Bacillus subtilis. Background technique [0002] Since the 1950s, with the rapid development of the chemical industry, a large number of pesticides and fertilizers have been developed and produced through chemical synthesis, and widely used in agriculture, making a huge contribution to the development of agriculture, making farmland fertility Enhanced, crop diseases and insect pests have been effectively controlled, and crop yields have also increased significantly. More than half a century has passed, due to the unrestrained use of chemical pesticides and chemical fertilizers, a series of problems have been brought to agricultural production, such as soil compaction, soil fertility decline, ecological imbalance, and increasing resistance of pests and diseases. People have gradually realized these ...

AI Technical Summary

Problems solved by technology

[0007] 3. There are almost no varieties with high resistance to soft rot on the market;

[0008] 4. Soil-borne diseases are serious, and it is difficult to break through the obstacles of crop rotation and scale;

[0009] 5. The konjac variety itself has strong persistence and strong dependence on the natural environment, and it is difficult to artificially domesticate and cultivate;

[0010] 6. The traditional chemical control is single and the control effect is poor. Therefore, we propose a control method based on Bacillus subtilis to radically cure konjac soft rot
