Ginger nematode is a soil-borne disease and it is very difficult to control. Due to the restriction of land resources and the increase in prices of ginger on the market, the phenomenon of double cropping is very common, resulting in aggravation of ginger nematode in recent years, resulting in a significant reduction in ginger production and quality. The finished ginger skin produced by a nematode-damaged plot is rough and the commodity value is reduced, and Jiangnong calls it "skin disease." I have been standing for many years to prove that the effect of fumigating soil with chloropicrin solution is very significant in preventing ginger nematode disease. First, the amount of 99.5% chloropicrin solution (Dalian Green Peak Chemical Co., Ltd.) 30 kg per mu. Second, the use of methods 1. Use winter and spring slack season, before the application of deep-turning the land 25 cm, leveling and thinning to maintain soil moisture. 2. Before entering the winter or early spring, use a special syringe to inject 3 ml of medicine every 30 centimeters into the hole to a depth of 15 centimeters. 3. Immediately after injection, plug the injection hole with soil and cover the mulch. Filming time: the soil temperature was between 5°C-15°C for 20-30 days; between 15°C-25°C for 10-15 days; between 25°C-30°C for 7-10 days. III. Benefit Analysis The trial was conducted on a severely affected block in Beima Town. The varieties used in the test plots and the control plots were Mianjiang, with the same soil conditions and the same management level. The control plots were not applied. On April 8th, the plants were covered with plastic film and harvested on October 22, and 4984 kilograms of high-quality ginger was harvested in the experimental plot, and no diseased ginger was found. The control field harvested 281 kilograms of disease-free ginger and 2960 kilograms of ginger. According to the market price, the premium ginger is 2 yuan per kilogram, and the diseased ginger is 0.6 yuan per kilogram. The experimental farm income is 9968 yuan, the control field income is 2338 yuan, and the application fee is 500 yuan. The application plot is better than the non-administration plot. Blocks increase 7,130 yuan per mu. IV. Precautions 1. After the film is peeled off, the residual liquid is volatilized to prevent burning. 2. Choose disease-free and robust ginger to prevent ginger-borne disease when planting. 3. Operators should pay attention to the direction of the wind when applying pesticides, operate in the wind, and wear gas masks to prevent poisoning. 4. Field managers should avoid walking around diseased plots to prevent human transmission. 5. Use pipe irrigation when watering to prevent water from spreading. 6. Use decomposed organic manure to prevent spread of fertilizer.
