How to Make Wheat Safe for Winter

The winter wheat growth is basically normal, but the overall growth is not as good as in previous years. To prevent the winter wheat from freezing and freezing, use the following measures to ensure that winter wheat is safely overwintered, in addition to using cold-resistant varieties and timely planting so that wheat seedlings can fully perform cold-resistance exercises.

First, repression. Comprehensive repression should be carried out when the soil begins to freeze and the surface has a certain dry soil layer. The surface soil temperature can be increased by 0.5 ~ 1 °C, especially in the case of loose and rough topsoil, shallow sowing, wheat fields and growing drought and windy conditions, the effect is particularly obvious. The repression of wheat fields has been sustainable until the soil is thawed.

Second, apply fertilizer. Application of 2 to 3 cm thick soil fertilizer in the wheat field can increase the daily average temperature of the tiller section by about 2°C. The application of soil excrement or the use of soil or soil for soil conversion can be performed by fertilizing soil and keeping warm.

Third, timely winter irrigation. The timely winter irrigation can stabilize the ground temperature and prevent freezing of dead seedlings. Second, it can sink the soil and crush the rubbish to eliminate the overwintering pests. The third is the combination of winter water and winter fertilizers, which can create good conditions for the return of spring wheat 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%.

Fourth, spraying chlorella. For plots that are sown too early and overgrowth, chlormequat can also be sprayed to control the internode elongation of the wheat seedlings, to enhance cold resistance, and to avoid or reduce loss of freezing damage. We will continue to monitor pests and diseases. Once we have reached the prevention and control targets, we will take measures to prevent and treat them as soon as possible.

During the overwintering period of strengthening field management, it is imperative to relax field management, block oblique roads, ban sheep and livestock, and prevent livestock and livestock from suffering.
