Seed treatment before sowing has important functions such as promoting early growth of wheat, increasing roots and tillering, and increasing grain weight. Commonly used seed treatment methods are as follows. As a Seed Cleaner and Grader Manufacturer, share with you.

Germination test: When the germination rate of the seeds to be sown is above 90%, the seeding rate can be increased according to the predetermined sowing rate. If the germination rate is between 85% and 90%, the seeding rate can be increased; if the germination rate is below 80%, the seeds should be replaced.

Selected seeds: if possible, it can be selected by a selection machine, and if there is no condition, it can be used to clean out the broken grains, shattered seeds, and debris by screening, wind and other methods.

Pile and cover the seeds at night until the teeth bite the seeds. Until it sounds. Be careful not to dry seeds on cement floors, iron plates, stone slabs, and asphalt pavements to prevent high temperature scalding the seeds and reduce the germination rate.

Chemical seed dressing: In order to prevent underground pests and various diseases and insect pests in the seedling stage, 100 grams of phoxim can be used for every 10 kilograms of wheat seeds, and 1 kilogram of water can be used to dress the seeds for 3 to 4 hours. After drying, they can be mixed with 15% phoxim 200 Grams.

Hormone seed soaking: In areas where drought and dry hot wind often occur, dressing seeds with 50 grams of drought-resistant agent No. 1 per acre and 1 kg of water can stimulate seedlings to take root, which is conducive to drought resistance and increase yield; seed soaking with 0.5% chlormequat before sowing in high-water and fertile land , It can promote the early tillering of wheat, the healthy growth of wheat seedlings, and the obvious effect of preventing wheat lodging.

Micro-fertilizer seed dressing: In areas lacking a certain trace element, according to local conditions, soak seeds with 0.2%～0.4% potassium dihydrogen phosphate, 0.05%～0.1% molybdic acid, 0.1%～0.2% zinc sulfate, 0.2% borax or boric acid solution , Have a certain effect on increasing production.

In addition, soaking the seeds to accelerate germination before sowing wheat in late sowing can accelerate the hydrolysis of nutrients in the seeds, promote the activity of enzymes, and facilitate early emergence and strong seedlings.
