Wheat timely winter irrigation, the first is to stabilize the temperature, to prevent the freezing of dead seedlings; the second is to be able to sink the soil, crush the rubbish, eliminate overwintering pests; third is the combination of winter water and winter fertilizer, can create good conditions for the spring wheat turn green and root growth. In addition, the saline-alkali wheat fields can be fed in winter and can also be alkali-modified. According to the survey, compared with unsealed winter wheat fields, the number of ears per mu increased by 123,000 spikes, the number of grains per spike increased by 6.7 grains, the grain weight increased by 1.3 grams, and the yield increased by 27%. Whether wheat needs winter irrigation and what time winter irrigation should mainly grasp the "three look":
One depends on lyricism. For winter wheat fields where the water holding capacity is less than 80% and water is poured before winter, winter irrigation should be performed.
Second, we must look at the situation. Single planting in more than 1.5 ~ 2 wheat fields, winter irrigation is more appropriate, generally weak seedlings, especially single seedlings of late sowing, it is best not to winter irrigation, or prone to frost damage; overgrown wheat field, you can postpone or not winter irrigation In order to control and prosper.
Third depends on the temperature. The appropriate time for wheat winter irrigation is generally started from the drop of the daily average temperature to 7-8°C, and ends at around 5°C. The people’s experience is: “The nights are frozen, the winter irrigation is just right.†The winter irrigation is too early and the temperature is high. Evaporation is too large to achieve the desired effect; winter irrigation is too late, the soil is frozen, the water cannot be infiltrated in time, the water in the ground area is frozen, the wheat seedlings suffocate and die under the ice, or form ice icicles, lift up the clods, pull Broken wheat roots, hanging wheat seedlings. The order of winter irrigation is generally to infiltrate poor clay land, low-lying land, and post-irrigation water-rich sand land; first to fill the second and third types of wheat fields where the bottom is insufficient or the surface of the table is poor. Early, and there is a long trend of wheat.
In addition, it should be noted that the amount of winter wheat irrigation should not be too large, in order to be able to soak, the day seepage is appropriate; generally about 50 to 60 cubic meters per mu. In order to save water, we must do the drainage and drainage facilities to prevent flooding; after the winter irrigation, we must timely remove the loose soil and bridge the cracks so as to increase the temperature and prevent the dead seedlings from being damaged by the wind.
