See seedling fertilization, seedlings normal plots of land can be applied to 5 kg of urea urea, weak seedlings may be appropriate to increase, Wang Miao should not topdressing nitrogen fertilizer, should be applied to plant ash or potash, from the role of lodging. We must do a good job of chemical weeding in the spring wheat field and do a clean ditch drainage work.

rape

We will continue to strengthen field management and attach importance to clean drainage and prevention and control of aphids, sclerotium, and other pests and diseases. Pay attention to topdressing fertilizer and boron spray outside the root. Fertilizer should be applied after the "Spring", generally about 10 kg per mu urea is appropriate. Boron spray is required twice, the first time in mid-February and the second in the early flowering period. The spraying concentration is 0.2%, and it is preferable to spray after dew.

vegetables

From late January to February, during the low temperature period of the year, rain and snow are flying, and low temperature and low illumination are typical features. The focus of vegetable production management is the management of vegetable seedlings, the timely establishment of timely cultivation of vegetables, the cultivation of melons and legumes, and the management of garden vegetables in the field.

1. For garden vegetables, mainly Chinese cabbage, Chinese cabbage, celery, lettuce, spinach, cauliflower, red cabbage, lettuce, etc., can be listed to grasp the timing of the market, early closing the market, for the next glutinous vegetable production vacated time and space. For those who are not yet listed, they must strengthen management, do top-dressing and laminating, and warm up and keep warm.

2. For gardening solanaceous fruit vegetables, the temperature in recent winter is lower than in previous years. Ice and snow disaster weather takes a long time. The management mainly prevents cold and humid and causes freezing damage. The prevention of “one cover and one cover” leads to harm and "Hunger" occurs. Take a variety of measures to achieve the purpose of warming and heat preservation, but we must also seize the management of good weather at noon during the high temperature period, strengthen ventilation, remove moisture, remove light from the light, increase the light, cover the film to keep the warmth, increase the temperature, and spray the fertilizer to control the water supply. Wet work, seize the cold tail warming time to do a good job in colonization and management of solanine vegetables in the greenhouse.

3, for cucumber, summer squash, kidney beans, kidney beans and other nursery, in the greenhouse to set up electric hotbed nutrition podcasting. Before sowing, seed soaking or seed dressing disinfection shall be done. The germination may be initiated by germination or electric blankets. Germination of radicles can be planted in nutrient bowls that are drizzled with bottom water. Boron covers the soil after sowing. Do a good job of warm water management.

Fruit trees

Continuing to make antifreeze protection work for the cold-tempered tree, pay attention to removing pathogens that overwintered and overwintering pests, and strengthen the application of pre-fertilizers to timely sparse or inflorescence fruit trees such as peaches, plums and pears.

1, before pouring frozen frozen water: can increase the soil moisture content, seal the winter ground temperature, watering is also one of the ways to prevent the late spring cold, frost.

2, the tree disc cover, cover grass: the soil insulation, moisturizing, covering the film can be carried out in the late autumn and early winter, covered grass in spring, summer and autumn can be carried out, covered with straw and more wheat straw, etc., about 75 kg per mu, The thickness should be 15 to 20 cm. If it is too thin, it will not achieve the effects of heat preservation, moisturizing and anti-freezing. After the grass is covered, the soil should be pressed properly to prevent wind and fire.

3, through the support of large branches, shake off the snow in time to prevent snow disasters. For branches that have been severely cut off by heavy snowfall, the wounds are sawed and cut as soon as possible. After applying protective agents such as wax liquid and Vaseline, wounds are healed with a plastic film.

4. The orchards cover 10-20cm thick weeds or crop stalks before the onset of low temperature. The stems and main branches can be insulated with straws; the young trees are dressed with straw after the Gaopu soil before cooling; before the extreme cooling, the orange orchards are prepared. Smoke smoke materials, before the advent of lit smoke fumes to prevent frost.

5. After the freezing damage, drain water in time to keep the soil loose and ventilate; remove dead leaves to prevent water evaporation from aggravating the frostbite face; after the temperature rises, when the spring buds germinate, the part where they germinate will be cut to this part, and the underground part will be cut off properly. , Thin-fat, diligent, continuous spraying 2-3 times full-foliage fertilizer, recovery measures in time to keep up with, to ensure the output of the year.

In addition, we must do early work potato potato cutting, germination and seeding film. Early preparations such as early rice, cotton and other seeds, shortages, and agricultural machinery repairs should be done early.
