Three good levels before wheat sowing

Affected by the rainy weather during wheat harvest, the quality of wheat seeds has declined this year. In order to ensure the emergence rate, wheat should be given three good levels before sowing.
Selection of seeds for the screening or wind selection, remove diseased grains, grains and debris, to improve the purity and purity of seeds.
Dry seeds are selected for sunny days for 5-6 hours to increase the germination rate. Be careful not to expose it to bright sunlight at noon, and at the same time, do not put the wheat seeds directly on the cement floor for sun damage to the embryos to affect germination.
Try to shoot early buds to determine the amount of use. You can choose two long bricks. After soaking in the water, place a piece in the small basin, add water to the surface of the water and flush with the top of the brick, put a small amount of test buds, and then press another long brick and put it in the sun. 2 ~3 days, observe the germination of the test buds
