Newly opened banana garden

Seedlings are forbidden to introduce seedlings from diseased areas. It is advisable to breed on the spot and to detect whether pathogenic bacteria are carried in the irrigation water. At the same time, attention should be paid to the treatment and disinfection of nutritious soil, and whether or not seedlings contain nematodes.

Water is good for the detection of water-borne pathogens and field irrigation and drainage. It is recommended to use drip irrigation or short spray.

Soil amendments are applied to the soil, in particular forest land or less-managed lands such as lime, calcium carbonate, and ash to increase soil pH.

Fertilizer application of high-quality bio-organic fertilizer (500 kg/mu or more) and supplement of liquid functional microbial fertilizer increased soil microbial diversity and soil organic matter content and prevented the occurrence of banana wilt disease.

In the process of disease cultivation, we pay attention to the occurrence of soil nematodes, especially the land that has been previously planted on melons. Nematodes complete a life cycle in about 25 days, so the wired larvae need to be processed once a month.

The banana garden with blight

In addition to the implementation of the technical measures for the new Kaiyuan Garden, it is also necessary to control the route of transmission to detect the presence of banana wilt pathogens in irrigation water (surface water). If there are germs, the water can be treated or replaced with groundwater.

Low incidence of banana garden (incidence < 5%) Planted with buds, biological fumigation treatment of the soil around the diseased plants, and at the same time strengthen the isolation of field irrigation and drainage and the occurrence of the disease, remove the buried plant in the soil or incineration, cover, deep trench isolation Such as, to avoid the spread of banana wilt pathogens, increase the amount of soil amendments and bio-organic fertilizers and liquid microbial organic fertilizer application times.

Middle incidence of banana garden (incidence < 15%) Green chemical fumigation combined with the application of a large number of bio-organic fertilizers and soil conditioners, strengthening field drainage management, planting resistant varieties.

High-risk banana gardens (incidence rate >20%) Select appropriate crop rotations for green chemical fumigation, and increase the application of bio-organic fertilizers and soil amendments, plant disease-tolerant varieties, and rotate in a rational manner.

Laser Distance Meter 60M

Digital 60m short range laser rangefinder is a laser measurement device which is supposed to replace tape measure, ruler, and other traditional length meauring tool. Laser ruler as its name, it is a electronic ruler which user laser to measure distance.
