Description
Technical Field
The invention relates to the technical field of crop planting, in particular to a method for preventing and controlling banana vascular wilt through drug regulation.
Background
The banana is one of four fruits in the south of China, is fragrant, sweet and delicious in taste, attractive in golden yellow peel and rich in pulp nutrition, and is the king of the traditional fruit. The method is mainly distributed in subtropical climate areas in south China for planting, and Guangxi, Guangdong, Hainan, Fujian and Yunnan are main planting areas of bananas. According to the statistics of agricultural departments in 2017, the banana planting area in China reaches 350 ten thousand mu, the yield reaches 280 hundred million yuan, and the banana planting area is one of the main fruits which are rich in vast farmers in the south of China.
The banana wilt disease is the absolute symptom of bananas, and is a dispute disease in banana gardens in main banana planting areas of Guangdong, Hainan, Guangxi, Hainan and the like since the banana blight disease is introduced into banana areas in China. Susceptible banana garden, one piece withered yellow, banana is extremely harvested. The development of banana industry is seriously threatened by the spread of blight, the planting area reaches 180 ten thousand mu in the highest peak of Guangxi in 2015, the planting area is reduced to only 80 ten thousand mu in 2018, the planting area is reduced to only 30 ten thousand mu in Hainan originally 100 ten thousand mu, the planting area is also greatly reduced in Guangdong and Yunnan, and the banana industry is seriously threatened due to the harm of the blight.
With the spread of the wilt, scientists in various countries in the world and scientific research departments at all levels in China invest huge scientific research expenses, collect experts, and carry out systematic research and attack on the banana wilt in many times, and pathogeny, mechanism, method and other aspects, but at present, the effect is not ideal, and a method for effectively treating and controlling the banana wilt cannot be found.
At present, the prevention and control research on banana vascular wilt mainly comprises two directions, firstly, the breeding of disease-resistant varieties is a long process, and the current high-resistance varieties cannot be popularized due to long quality and growth period. The second method is a biological control method for controlling the fusarium wilt by using bacteria, but the effect on controlling the fusarium wilt is unstable due to the instability of the bacteria in soil. Therefore, a simple and effective method for preventing and treating the blight is needed.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
