The low temperature in the morning and evening in winter is likely to cause freezing damage in field crops. In the process of planting wheat, if it encounters less rain and long drought, it will affect the emergence and growth of wheat. Therefore, in order to produce high-yielding wheat in the coming year, planters should do winter wheat cultivation and management, such as wheat field anti-freezing seedlings, seedling winter hair, dredging and anti-staining, etc. The specific small series will be explained in detail below.

First, due to seedlings

1. Miao fertilizer is the main measure to promote the growth of wheat seedlings. The lack of nutrients in the seedling stage of wheat seedlings will slow down the growth. Therefore, in the wheat field where the base fertilizer is applied, 10 kg of urea is applied per mu. In the wheat field where no phosphorus or potassium fertilizer or compound fertilizer is applied, 25 kg of compound fertilizer containing 15% of nitrogen, phosphorus and potassium is applied per mu.

2, pay attention to the local weather forecast, fertilization before rain, is conducive to improve fertilizer efficiency.

Second, seize the chemical weeding

1. Grasp the timing of weeding when the winter cold wave is warmed up and the minimum temperature is above 5 °C. Apply the herbicide to the wheat field of the wheat seedlings with 2 leaves and more than 1 heart. Use 150 kg of herbicide Isoprolong powder per mu. 50 kg of water, and then evenly sprayed on the soil surface of the wheat field to ensure the herbicidal effect, as early as possible, grasp the small medication.

2. For the serious occurrence of locusts, at the same time as weeding, spray insecticides and treat mites.

Third, the governing ditch covering soil, anti-staining and anti-freezing

1. After the wheat field is ditched, for the field where the ditch system is not cleaned, it is necessary to dredge the ditch system in time, dredge the intersection between the horizontal ditch and the vertical ditch, ensure that the horizontal and vertical ditch communicate, open and deepen the total outflow ditch of the Tiantou, and connect To the roadside ditch.

2, prevent rain damage caused by rain.

3, the ditch mud covered in the wheat seedlings that have not been cultivated, to protect against cold and freeze.

Fourth, wheat field shoot wheat, prevent lodging

For the early and dense wheat fields, it is necessary to take the wheat or the wheat when the soil is dry. It can protect the seedlings from the roots. At present, it can prevent freezing and strong seedlings. More importantly, it can prevent the late lodging.
