Embodiment 1
[0038] Luoxu Town, Wuming County, Nanning City, Guangxi Province is an epidemic area of banana wilt. There is a 60 mu newly planted banana garden in Luoxu Town. The previous crop of bananas is fast-growing eucalyptus.
[0039] like figure 1 Shown, adopt technical scheme of the present invention to control the cultivation method that banana fusarium wilt spreads between gardens to set banana garden, comprising:
[0040] (1) Excavate isolation ditch 1 with a width of 120 cm and a depth of 150 cm around the banana orchard.
[0041] (2) Close to the inner ditch of the isolation ditch, the isolation zone 2 shall be set up for isolation with the fence net.
[0042] (3) Set up agricultural roads 3 required for people to move around in the banana orchard.
[0043] (4) Set up the entrance of the banana garden, set the gate 6 of the banana garden at the entrance, lay a layer of 8cm thick quicklime layer on the road of 400cm inside and outside the gate 6 of the banana garden, and se...
Embodiment 2
[0048] Dingdang Town, Longan County, Nanning City, Guangxi Province is a banana wilt-affected area. Dingdang Town newly planted 180 mu of bananas, which were isolated into three independent banana gardens of 60 mu. The previous crops for planting bananas were sugar cane and wax gourd.
[0049] like figure 1 Shown, adopt technical solution of the present invention to set banana garden, comprising:
[0050] (1) Excavate isolation ditch 1 with a width of 140 cm and a depth of 180 cm around the banana orchard.
[0051] (2) The surrounding ditch next to the isolation ditch will continue to be isolated with barbed wire, and the isolation zone 2 will be set.
[0052] (3) Set up agricultural roads 3 required for people to move around in the banana orchard.
[0053] (4) Set up a buffer zone 4 within a range of 250cm wide on both sides of all agricultural roads 3 in the banana orchard, and plant chives as a buffer crop.
[0054](5) Set up the entrance of the banana garden, set the g...

Abstract
The invention provides a cultivation method for preventing banana vasicular wilt from spreading among plantations. The cultivation method comprises the steps of determining unit area of an independently isolated banana plantation and arranging isolation furrows around the banana plantation; arranging isolation strips around the furrow edges in the isolation furrows; arranging a banana plantation entrance and laying sterilization layers on roads inside and outside the banana plantation entrance; arranging a farm-oriented road for workers to walk in the banana plantation; and arranging buffer strips on the two sides of the farm-oriented road, wherein the buffer strips are non-host crops that are planted on the two sides of the farm-oriented road and have sterilization effects. According to the technical scheme, the problem that the vasicular wilt is spread out of the banana plantations infected with the disease and spread into banana plantations uninfected with the disease is solved, the spreading speed of the vasicular wilt in banana planting regions is effectively controlled, the vasicular wilt attack rate of a newly-developed banana plantation can be controlled below 10%, and the spreading speed of the vasicular wilt from the banana plantations infected with the disease to the banana plantations uninfected with the disease is greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of banana cultivation, in particular to a cultivation method for controlling the spread of banana fusarium wilt between gardens. Background technique [0002] Banana wilt is caused by Fusarium oxysporum Cuban specification ( Fusarium oxysporum f. sp. cubes , Foc ) is a devastating plant disease caused by infection. The pathogen mainly invades from the roots of bananas. Once a banana tree is infected, it will cause the whole plant to wither until it dies. The disease was first discovered in Queensland, Australia in 1874. At present, Fusarium wilt has differentiated into 4 pathogenic physiological races, and is widely distributed in banana producing areas in Asia, Africa, Australia, South Pacific and tropical America (Pegg et al. , 1996). Among them, race 4 has the widest host range and can infect almost all banana cultivars including Cavendish banana. Banana Fusarium wilt infected by race 4 has been di...
