Seed treatment is the first line of defense to prevent pests and diseases. To ensure that Miao is full and Miao is strong. The processing method is as follows:

Selection of corn seeds includes ear selection and grain selection. When the ear selection is to dry the ears on the field, the mixed, poorly mature, diseased, and rotted ears are removed and dried for threshing. The grain selection is selected to remove small and glutinous grains before sowing, and to remove mold, broken, insect particles and sundries, so that the size is even and full, which is beneficial to Miaoquan and Miaoqi.

Seed treatment and sun-selection for 2~3 days on sunny days will help to increase the germination rate, early emergence and reduce silk smut.

Soaking seeds can promote the germination of seeds, the emergence of seedlings, and the tidy seedlings. The method is soaking in cold water for 12 to 24 hours; soaking in warm water at 50 ° C for 6 to 12 hours. Soaking seeds should pay attention to the time of full-bodied hard-type seeds, and the time of glutinous and dentate seeds should be short; the seeds soaked should not be sun-dried, not piled up, and should not be packed with plastic bags; When the ground is dry and the sensation is insufficient, do not soak seeds; soaked seeds should be planted in time.

The dressing of the medicament can be used to prevent the corn smut by mixing 15% of the rust-wet WP 400-600 g, and the seedling agent can be used for seed dressing and coating to control the underground pests.
