Description
Technical Field
The invention belongs to the technical field of disease prevention and control, and particularly relates to a pesticide fertilizer, an application method and application thereof, and a method for preventing lotus rot disease.
Background
Lotus seed, a name of traditional Chinese medicine, is a dried mature seed of Nelumbo nuciferakgaertn (Nymphaeaceae), and has the effects of tonifying spleen, stopping diarrhea, stopping leukorrhagia, tonifying kidney, arresting seminal emission, nourishing heart and soothing nerves. Is commonly used for spleen deficiency diarrhea, leukorrhagia, spermatorrhea, palpitation and insomnia, and is a 'medicinal and edible' aquatic cash crop. The lotus is a perennial root herbaceous plant, has a long cultivation history in China, is widely distributed, and is planted in the south and the north. Jiangxi, Fujian and Hunan are three famous lotus seed producing areas in China, and lotus seed planting has become the support industry in a plurality of areas.
The lotus rot disease is commonly called as the epidemic disease of the lotus, is the most main disease of the lotus and occurs in lotus planting areas all over the country. The lotus rot disease mainly causes the decay of the penis, node and root of the lotus root, and the withering and wilting of leaves and cyanines, the yield of the general ill lotus seeds is reduced by more than 30-40%, and the yield of the severely ill lotus seeds is reduced by more than 80%, even the serious ill lotus seeds are completely harvested. The lotus rot disease is caused by fusarium oxysporum and lotus specialization, belongs to soil-borne diseases, can directly infect lotus vascular bundles, but is more likely to invade from wounds of lotus roots and lotus penis caused by latent root nematodes and root eating golden yellow beetles to cause tissue ulceration and wilting. As hyphae can survive for 3-4 years in disease residues and can decay for 5-6 years in soil, particularly chlamydospores survive for a longer time, great difficulty is brought to prevention and treatment of the lotus rot disease. At present, no ideal agent for preventing and treating lotus rot is available, the soil environment condition is complex, the overground part of the lotus does not show symptoms during early-stage disease attack and is not easy to be found, and when the overground part shows symptoms, the symptoms enter the middle and later stages of the disease, and the aquatic environment is added, so that the drug effect of the bactericide is limited. The lotus seed varieties popularized and applied in production have different degrees of infection, and no high-resistance varieties are found. The existing prevention and treatment mainly uses medicaments, the prevention and treatment effect is poor, and the use of a large amount of pesticides easily pollutes the environment. Therefore, the development of a new operable technology for preventing and treating lotus rot becomes a necessary way for realizing sustainable development of the lotus seed industry in China.
For example, Chinese patent CN103960019B discloses a method for preventing and treating putrefaction disease in the planting of seed lotus, which is a comprehensive prevention and treatment method mainly based on prevention by matching four steps of field disinfection, lotus seed disinfection, vertical leaf application and diseased plant treatment aiming at the putrefaction disease in the planting process of seed lotus. However, the method only aims at the pathogenic bacteria of the lotus rot disease, neglects the promotion effect of the latent root nematodes, the root eating golden yellow beetles and the like on the occurrence of the rot disease, and influences the control effect. In addition, the sulfur is used for soil disinfection, the sulfur has an acidification effect on the soil, the main lotus seed producing areas in China, such as Jiangxi, Hunan, Fujian, Hubei and the like, are red soil, the soil has a serious acidification problem, the acidification is aggravated by the sulfur, and the incidence rate of lotus rot disease is increased by the acid soil. Therefore, the establishment of an efficient, environment-friendly and economic lotus rot disease comprehensive prevention and control technology is urgently needed, the incidence rate of rot diseases is reduced, and the yield and the quality of lotus seeds are improved.
