Clever treatment of root-knot nematode disease

The use of wheat straw, lime nitrogen and high temperature soil sterilization, simple method, less money, good effect, can be drawn on the spot, without pesticides, reduce the pollution of vegetables, farmers are easily accepted. The specific practices are as follows: Prior to planting, each layer of soil applied per acre shall contain 75kg to 100kg of lime nitrogen, 1000kg to 2000kg of wheat straw, or 3000kg to 4000kg of chicken manure. After irrigation, the irrigation volume will reach saturation level. The transparent plastic film is tightly covered and tightly closed to maintain a certain space between the film and the soil, so as to increase the temperature of the ground and enhance the bactericidal and insecticidal effects. Closed greenhouse or greenhouse, drowsy shed 20 days to 30 days. After the dwelling is over, the ventilation can be opened according to the soil moisture conditions, and the soil moisture can be adjusted, and then the soil can be cultivated after loosening the soil. The best time to apply this method is to choose a period with high summer temperatures, little rain, and idle greenhouses, usually from late May to late August. After a few days of such treatment, the lime nitrogen is exothermic, prompting the rot of the grass to exothermal, plus the summer heat, the shed film insulation, and the average surface temperature during the day can reach 65°C to 70°C. The 10 cm soil temperature is also above 50°C, and the 20 cm soil temperature also exceeds 45°C. The average soil temperature in the plough layer is above 45°C. Scientific practice has proven that some pathogens, such as root-knot nematode disease, which mainly depend on soil, are at temperatures above 40°C and can all die within a few days. In addition, the intermediate products produced by the decomposition of lime nitrogen into urea have a killing effect on harmful organisms, so in addition to killing root-knot nematodes, it also has a good killing effect on wilt disease, bacterial wilt and other pathogens. It also has a certain role in killing some underground pests in the soil. Lime nitrogen also neutralizes the acidity of the soil caused by the extensive application of fertilizers over a long period of time. After the grass rots, increasing soil organic matter can improve soil physical and chemical properties, fertility and fertility, and promote the growth of vegetable roots. Lime nitrogen is hydrolyzed into urea in the soil and can be further hydrolyzed to ammonium carbonate, which becomes a plant-absorbable nitrogen nutrient. Practice has proved that every time it is processed once, it is possible to continuously cultivate 2 to 3 baskets of vegetables, which has been welcomed by farmers in the production practice.



1, supplementary poultry to all sorts of vitamins, amino acids, nutrient requirements, improve drug-application growth rate, effectively improve the quality of poultry. Improve the feed conversion rate.

2, enhance egg weight, improve the eggshell quality.

3, can increase rate, delay poultry , cattle and sheep reproductive function decline, extend the egg laying peak.

4, disease recovery use this product, can quickly recover the body function.

5, such as Chinese medicine astragalus extract to join, can stimulate the body produce interferon, interference viral replication, improving the body immunity.

6, ease because of vaccination, and turn group of the weather changes of the stress reaction.
