Cultivation management method for controlling banana wilt

Abstract

The invention relates to the new technical field of disease control during plant cultivation, in particular to a cultivation management method for controlling banana wilt. The cultivation management method comprises the following steps: turning up the soil of a banana plantation and drying the soil in the sun for 7 to 10 days before banana seedlings are planted; selecting banana seedlings which pass quarantine inspection as seedlings; selecting 30 percent metalaxyl-hymexazol as a disinfecting and disease preventing agent for early, middle and later stage management of banana plants, absorbing and solidifying a disinfectant prepared from the metalaxyl-hymexazol by using a water-retaining agent to obtain a solid disinfectant, distributing the solid disinfectant at the peripheries of roots of the planted banana seedlings to make the solid disinfectant slowly release the disinfectant to eliminate pathogenic bacteria in the soil, wherein the disinfecting effect can last for 1 to 2 months; irrigating the disinfectant every two months, absorbing and storing the disinfectant by using a water-retaining agent, and continuously disinfecting for 1 to 2 months; and after the roots of banana plants are irrigated with the disinfectant each time, spraying the disinfectant onto the whole banana plants until banana fruits are harvested.

Description

technical field [0001] The invention relates to a new technical field of disease prevention and control during plant cultivation, in particular to a cultivation management method for preventing and controlling banana wilt. technical background [0002] Banana Fusarium wilt, caused by the infection of Fusarium oxysporum Cuban-specialized, is a devastating disease and is subject to international phytosanitary measures. The pathogen of banana fusarium wilt survives in the soil for several years. Generally, even if the disease is controlled, the banana orchard with the disease will reduce the yield by more than 20%, and the severe banana orchard may even fail to harvest, causing serious losses. [0003] Banana Fusarium Wilt is generally a soil-borne disease, or the source of infection of diseased banana seedlings. At present, the prevention and control methods of banana fusarium wilt include: 1. Select disease-resistant varieties. 2. Carry out crop rotation with other crops to...
