When scribing, pay attention to mastering shallow and fine squats, and push the shovel while smashing; if you suppress it before slashing, you can make the soil not empty, so you can receive the effect of Panasonic, tamping and protecting.
Repression: In the early spring, the wheat field can be crushed, and the cracks can be crushed to close the cracks, so that the wheat roots are in close contact with the soil, preventing cold air from invading and damaging the wheat seedlings. At the same time, the repression also has a lifting effect, which can increase the water content of the soil surface layer, and is beneficial to alleviate the low temperature chilling damage.
Fertilization: Wheat fertilization in early spring can make up for winter soil fertility consumption, increase nutrient accumulation, promote the growth of wheat seedlings, and resist or reduce early spring frost damage, especially in the years when winter temperatures are high, wheat seedlings continue to grow, and soil fertility is high. Fertilization in early spring is especially important. Wheat fertilization in early spring should seize the favorable opportunity of the soil just thawing and returning to the pulp, and borrowing it to open the ditch; it should not be watered to avoid lowering the ground temperature and affecting the growth of wheat seedlings.
Spraying: When the wheat is greened to the body, the spraying of 200ppm paclobutrazol solution per acre is 30-40 kg, which can inhibit the growth of wheat seedlings and enhance the cold resistance.
