Clear or clean the pastoral. Cotton bollworms, red spiders, aphids, thrips, and blind stink bugs can be overwintered on dead branches, fallen leaves, bells, and weeds left in the cotton fields. Clear up the pastoral areas, remove dead branches, fallen leaves, and drop bells. Eradicate the weeds around the cotton fields to effectively eliminate the above-mentioned overwintering pests. However, the scavenge must be concentrated and timely burned or buried. Turn over to turn the soil deep. Cotton bollworms, ground tigers, tawny moths, bridge-building moths and other wintering in the soil, can be implemented to turn soil killing measures. Turning soil can also increase soil permeability, accelerate soil maturation, and increase soil fertility. The soil is required to be 30 to 40 centimeters in depth. The topsoil is turned to the bottom, and the subsoil is turned to the top. The large earth blocks that are turned up will not be broken to facilitate winter weathering. Irrigate and irrigate the insecticide. Irrigation on the basis of earth turning can more effectively kill overwintering pests in the soil. According to the experiment, after the soil is poured and poured, the mortality rate of overwintering bollworms in the soil can reach more than 90%. Irrigation should be carried out on the "39" days, and it must be filled with water. The irrigation volume per mu is generally 80 to 120 cubic meters. Fill the clay a little bit more, and the loam can be a little less. The irrigation method is suitable for furrow irrigation, so that the water is soaked slowly, avoid flood irrigation, irrigation can also enhance the water storage capacity of the soil. Smoke is the fumigation of drugs. Red-bottleworms, anthracnose pathogens, carrageenans, red-rot pathogens and other pests can be attached to the seeds for wintering and fumigation can kill 98% of the pink bollworms and some of the pathogens. The method is to first seal the gap in the warehouse, and use 32-37 grams of methyl bromide per cubic meter of space for 3 days. The source of extinction is to eliminate the source of insects in the storage place. The cotton bollworm mainly hides in the gap between the four sides of the flower storage warehouse and the ginning factory. Therefore, it should be plastered in the four-wall spraying plant of the flower plant, and the gap should be filled. Drying tools must be washed with boiling water.
