Cotton seed treatment It is to prevent seedling diseases, prevent emergence of tall feet and achieve cotton. Whole seeding One of the key technologies. Because the existing seed processing technology can only achieve the sulfuric acid develvet and selection treatment, and the coating technology can not keep up with it, farmers often carry out seed treatment because of improper operation techniques (such as the type and dosage of pesticides), which may lead to the emergence of seedlings or fail to achieve the desired effect of seed treatment. Therefore, mastering the seed treatment technology is very important. In the process of seed treatment, we should pay attention to the following problems.

After the seed preparation is done, the seeds should be selected and dried. The main selection is to remove sick seeds, seeds, seeds and seeds. Seed drying can accelerate seed ripening and sunny days for 2 days to 3 days. It is not allowed to insolate on the cement floor to prevent damage to the physiological activity of the seeds.

The selection of insecticides should be based on the prevention of seedling diseases and the use of carbendazim. Wei Fu costs much and does not advocate using it. Generally, plastic film mulching can be used for less rainfall or drilling. It can be used as enemies, pine or carbendazim. When the demand is good and rain is heavy, the use of enemy or pine can be reduced. Prevention of insect pests at seedling stage can be mixed with 3911 or methyl sulphur phosphorus. It is advisable to prevent the use of DPC.

The dosage of foxpine was 0.3%, 2.5% of carbendazim, and 0.2% of that of Wei Fu. The dosage of 3911 or methyl sulphur phosphorus can not be increased at will, otherwise it is easy to produce phytotoxicity, generally 0.5% of seed consumption. The dosage of DPC should be considered. seedling stage For stable growing varieties, the amount of reducing amine can be used less; while the seedlings with vigorous growth and easy to form tall foot seedlings, the amount of the use of DPC can be increased appropriately. The general dosage of DPC is not more than 0.04% of the seed consumption.

Good results. According to the above dosage, 100 grams of seed should be weighed at 500 kg, 3911300 grams, and 20 grams to 40 grams. The first step is to use a small amount of water to dissolve the amino acid, then add 5 kg of water to the sprayer, then add 3911 and dissolve the shrink amine to mix it, spray it on the side and turn it over. First spray half of the liquid, spray it slightly after drying, spray the remaining liquid. After spraying evenly, mix the enemy pine powder with the seed when it is humid, and then dry it out for 24 hours. When seed dressing is used for seed dressing, the mixture of fungicides, shortening, and insecticides is usually mixed first. It is more troublesome to do seed dressing several times.
