Description

Banana garden seed-turning continuous cropping method Technical Field The invention relates to the technical field of agricultural tools, in particular to a banana garden seed turning continuous cropping method. Background Bananas account for about 1/5 of the total yield of a single crop in tropical regions of China, and play a role in the agricultural economy of the hot regions. However, as banana vascular wilt bursts in large areas of our country, the banana industry in our country suffers from unprecedented survival pressures, and many banana areas have undergone industrial transfer from Hainan, guangdong to Guangxi and Yunnan, etc., or from domestic to Laos, burma, etc. Aiming at the world problem of banana wilt, the banana industry technology and related technological staff in China jointly develop a technical attack, a series of banana wilt-resistant varieties are bred, a soil conditioning method is formed, and a wilt pathogen prevention and control agent or a microbial inoculum and a matched cultivation technology are screened out. However, in practical production, there are many management steps, such as the self-management level or the banana garden disease condition, which cannot accurately grasp the core links of banana wilt prevention and control, especially the banana garden management for banana wilt serious disease. In the past, aiming at banana fields with serious banana wilt, other crops or paddy-upland rotation over 2 years are generally suggested, and disease-resistant varieties are planted and matched with cultivation technology. However, in production, many severe banana gardens are often managed by the reason that the selection of disease-resistant varieties is inconvenient, the rotation period is long, the cost is greatly increased, the processing of the matched cultivation core links is improper, and the like, so that the management of the severe banana gardens is failed. How to shorten the crop rotation period of the severe banana garden, reduce the incidence rate of the wilt and improve the economic benefit of the severe banana garden is a working problem which must be overcome by the management of the severe banana garden. Bananas are perennial herbs, and a large number of buds are grown each year. In the technology for removing redundant buds, the traditional manual bare-handed removing or shoveling method is used for removing the buds, underground bulbs of the parent plant can be torn when the damage to the parent plant is serious, huge wounds are caused, diseases are easy to infect, more buds are stimulated to germinate, tools such as pointed steel drills and screwdrivers are used, compared with hoe heads, the direct damage to the parent plant is reduced, but the growing points cannot be damaged accurately, larger wounds still can be caused, the existing bud cutting and core digging method is small in wounds, low in infection risk and capable of effectively inhibiting the buds from regenerating, but the depth and the position of the growing points need to be judged accurately, and compared with simple shoveling, single operation time is long. Disclosure of Invention The invention mainly aims to provide a banana garden seed turning continuous cropping method and device, which aims to effectively reduce infection of pathogenic bacteria such as banana vascular wilt and the like, thereby improving banana output value. In order to achieve the above purpose, the invention provides a banana garden seed-turning continuous cropping method, which comprises the following steps: S1, seed turning and continuous cropping, namely selecting a sheet area with the incidence rate of banana vascular wilt exceeding 20% for regional seed turning, and fully turning the whole banana garden with the incidence rate of banana vascular wilt exceeding 20%; S2, cultivating seedlings, improving soil and protecting root systems, namely protecting the root systems, paving water permeable and breathable silver black films in a banana garden in an interlaced manner, covering grass prevention by using banana leaves or bud sucking residues in a ditch, and removing non-target plants; s3, digging deep ditches in the area easy to be waterlogged and draining water before the rainy season comes, and performing drip irrigation on daily drip water according to the soil moisture requirement of banana growth; s4, plant protection and control, namely, adding water to irrigate roots by using trifluoropyridine amine, a microbial agent A or fluopyram suspending agent, metalaxyl fludioxonil and a microbial agent B before new planting, before covering a film, after starting spring and before bud extraction, adding a spring leaf spring copper quinoline agent to spray banana stems and spray banana heads in a daily pesticide spraying process, using cyhalothrin to irrigate roots and control in a new planting period, periodically inspecting, flatly cutting unreserved buds, and adopting a bud sucking removing device to excavate growth
