Seed treatment skills of planting Wheat

Disinfection of wheat seeds before sowing can kill all kinds of germs attached to wheat seeds, such as smut, scab, rust and powdery mildew, etc., improve the germination rate of wheat seeds, make wheat seedlings strong, grow early and quickly, and obtain high yield.

Sunning seeds for 1~2 days in sunny and high temperature weather before sowing, not only eliminate mildew and sterilization, but also sunburn all kinds of pests. However, attention should be paid to: drying seeds on plastic sheets or soil wheat fields, not on cement drying fields.

Seed dressing with triadimefon 15~20 days before sowing can inhibit rust, powdery mildew and other diseases. 2 grams of triadimefon is used for each kilogram of wheat seeds, and the seeds are fully stirred by a seed dressing device and then sealed and stacked for 1 to 2 days.

The wheat seeds are soaked in hot water at 50℃~55℃ for 10 minutes, immediately soaked in cold water for 5 minutes after being picked up, and then put in hot water at 50℃~60℃. This is repeated several times, from hot to cold, and then from cold to hot, so that the bacteria do not adapt to the rapid changes in water temperature and death, and finally picked up to dry to be sown.

Lime water soaking seeds about 8 days before sowing, with 1 kg of quicklime water, first with a small amount of water to open, and then put into the tank or barrel, and then add 100 kg of water, fully stir after soaking seeds 60~70 kg. Soak the seeds for 24 hours, then remove the seeds and wash them with clean water to dry them. This method should pay attention to: lime to use white blocks of new lime, should not be used for a long time or has absorbed moisture disintegration of loose lime. Soaking period shall not be stirred, so as not to form the lime film layer on the water surface (this film layer can isolate the air and cause the bacteria on the wheat grains to die due to lack of oxygen) damage and affect the effect.
