Seed dressing, disease prevention and pest control Disease prevention in the past two years, soil diseases, rapid development of wheat full-blown disease, post-emergence chemical control effect is not ideal. The seed dressing of wheat during sowing time can effectively kill the germs in the soil and on the surface of seeds, and also have a certain preventive effect on wheat sheath blight, smut, and root rot. The method is: with 3% enemy Dan 50 ~ 100 ml +2.5% Celestius 10 ~ 20 ml, 100% ~ 150% ml of water mixed, you can mix wheat 10 kg (mu dose). 12.5% ​​full-escape water suspension concentrate 20 to 40 ml, 150 ml of mixed water for 10 kg. In addition, due to the heavy land mass of the disease, a large amount of bacteria was accumulated on the surface of the soil. During the sowing, the depth of cultivation could be 40 cm to reduce the occurrence of diseases. The method for controlling the underground pests is to use 40% methylisophosphorus, evenly mix 100g or 20% methylisophosulfide 150g with 3kg of water, spray on 50kg of wheat seeds, air dry and sowing, and effectively Prevention of underground tigers, earthworms, and other adult pests. Biogas slurry dressing improves wheat resistance Put the seed into a plastic permeable bag that is good in water permeability, strong, durable, and clean. Since the seeds swell after being absorbed by water, they should not be filled too much. Usually, the bag contains 15 to 20 kilograms. Pull the bag containing the seed into the biogas slurry in the middle of the normal gas-generating digester discharge chamber, place a wooden stick on the discharge port, and tie the other end of the rope into the middle of the wooden stick to suspend the bag. s position. Soaking time is generally 12 hours. After soaking the seeds, the seed bag is put forward, and the biogas slurry is drained. The seeds are removed and washed with clean water, spread out and dried, and then sowed. Choose the seeds All wheat culms, head blights, and smuts occur in heavy plots. Since the surface of wheat seeds has a certain bacterium source, the harvested wheat is strictly prohibited. In addition, sectioned wheat and wild oats are the weeds that have occurred in some wheat fields in the past two years. Because of its strong fertility, maturation is easy to fall off, it is difficult to control, and some are already mixed in wheat, so they cannot be kept as seeds. No hurry to control wheat midge It is not advisable to control wheat midge during sowing. If poisonous soil is spread during the wheat sowing, the wheat midge dormant at a depth of 15 to 20 cm in the soil layer, does not feed, does not exchange material with the outside world, and has a layer of earthworms in vitro. The medicine is basically ineffective. Two key stages of prevention and control of wheat midge prevention and control are the prevention and treatment of poisonous soil in the flood season, usually in mid-April; the second is the prevention and control of spraying in adults, generally in early May.
