How does the soil before sowing kill insecticide? Soil insecticidal sterilization is a strict process before sowing, which can effectively kill fungi, bacteria, nematodes, weeds, soil-borne viruses, underground pests and rodents in the soil. It can well solve the hidden dangers of high value-added crops and significantly increase the yield and quality of crops.
I believe that many farmers and friends often do not achieve their ideal results when sterilizing the soil. Today, I have compiled some good results that can effectively solve the problem of soil insecticidal sterilization.
1 Solar soil disinfection method: We can use 800-1000 kg of wheat straw or straw per acre in the summer, and weave it into 4-6 cm long, then spread it evenly on the ground, and then evenly apply 20-25 kg of lime. Sprinkle, turn the ground, algae water, film, and seal the greenhouse for 15-20 days. At this time, the surface temperature can reach 70 °C or above, and the temperature of 10 cm underground can reach 50-60 °C, which can effectively kill the bacteria in the soil and Nematodes, of course, this method is only suitable for greenhouses in greenhouses. The open field can be exposed to the ground evenly on the concrete floor or other hard ground, and the temperature can also kill the larvae as well as adults and germs. If you can spray 50% more yin WP during drying, add 50% phoxim emulsifiable concentrate or 5% avermectin with spray and mix, and lead or assist insecticidal sterilization is better.
2 poison disinfection method: the method of using toxic soil, the general preparation method of toxic soil is to mix a certain amount of pesticides and fine soil with certain humidity, and then can be carried out by ditch application, hole application or spreading method. The agents are carbendazim, thiophanate-methyl, Bacillus subtilis and the like. And all three drugs can be mixed.
3 liquid disinfection and insecticide method: dilute the liquid with a certain proportion of water into a liquid, spray it on the surface of the soil with a sprayer, so that the liquid penetrates into the soil, kills the bacteria and insects in the soil, and uses the medicine. Liquid disinfection and insecticide commonly used chlorpyrifos, avermectin, phoxim.
Normally we should also maintain the humidity of the soil, the soil moisture should be between 65% and 85%, which is conducive to the growth of crop seedlings.
The above is a small series for everyone to sort out some methods of soil insecticidal sterilization before and after sowing. If you have better experience, welcome the agricultural friends to put forward more valuable opinions.
