Right now, wheat is about to usher in an important winter season. The growth of wheat in winter is the basis for high yield of wheat. It is recommended to freeze the water in good time, suppress it in winter, keep the seedlings safely in winter, and lay a foundation for the water management in the spring season.
Pouring adequate amount of frozen water in a timely manner
Frozen water should be poured at a daily average temperature of 3°C-5°C (late November), and should be stopped when the temperature drops to 0°C. Usually 6-8 hours of irrigation, irrigation of 40-50 square meters per acre, according to the discretion of the soil moisture treatment. In areas with appropriate vegetation, the amount of frozen water can be reduced appropriately. Inferior base fertilizer or planting late, poor seedling plots, can be combined with frozen water Mushi about 3 kg of nitrogen fertilizer, in order to promote the growth of wheat roots under the bar.
Winter suppression of seedlings wintering
At the beginning of the winter, the wheat is pressed, broken, and sealed.
In the beginning of winter, after the frozen water is poured in wheat, in the first half of December, the local surface undergoes freezing and thawing to become dry and cracked. The cracks will occur during the winter. There will be more rubbish, more cracks, more surface stalks, soil overburden and shallow sowing. Wheat fields must be crushed with wheat in the early winter to crush slag, make up for cracks, reduce evaporation of soil moisture, and keep the seedlings safe for winter.
At the end of the winter, the wheat is pressed and the earthworms are reduced to reduce the dry soil layer.
At the end of winter (from late February to early March), the pressure wheat can also be used to break up the rubbish, close the cracks, compact the surface dry soil, reduce the evaporation of soil moisture, lift the soil, protect the thick soil layer, and prevent the wheat sprouts from wilting. , Bao Miao safe wintering effect. In addition to the wheat seedlings being small and the seeding ditch deeper than the wheat, the land will be buried in the soil and the rest of the wheat fields should be repressed.
Winter wheat technical requirements
Repression time: The repression should be performed at a maximum temperature of more than 3°C, before and after noon, the thawing of the wheat seedlings becomes soft, and the ground surface is thawed and crisped so as to avoid breaking the wheat seedlings.
Repression method: It is recommended to use a smooth winter wheat roller. Operational points: First, the tractor's walking speed should be 6-8 kilometers per hour in the 1st range. It is not advisable to use a fast speed to ensure the quality of the repression. The second is to prevent leakage pressure. The third is to adjust the weight of the roller according to the soil conditions.å· å¤š 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多 多.
