Planting techniques of Cucumber in Winter

First of all, set up the greenhouse by November and deal with the plots to be planted, including disinfection, fertilization and ridging. Then the seedlings were planted, and the greenhouse temperature was kept at about 30 degrees after planting, and the seedlings were slow half a month later. Then control the application of water and fertilizer, and do a good job in the prevention and control of diseases and insect pests.

Attention should be paid to fertilizing cucumbers in winter:

1. Fertilization according to different growth stages of cucumber

Cucumber seedling stage to ensure the absorption of normal nutrients, the amount of fertilizer should be less, the concentration should be low; in the full fruit stage, the amount of fertilizer should be larger, and the concentration should be higher. Some farmers use 200 kilograms of diammonium phosphate at a time, so it is unscientific to obtain high yield by using diammonium phosphate alone.

two。 Fertilize according to the soil condition

If the use of topdressing with water, the amount should depend on the soil condition, the soil is dry, the concentration is low, and the amount of topdressing is more. When the soil is moist, the concentration is higher and the amount of fertilizer is less. The ability of sandy soil to conserve water and fertilizer is poor, which should be a small number of times; the ability of clayey soil to conserve water and fertilizer is strong, and the times of fertilization should be less, but the amount of fertilizer should be more each time.

3. Fertilize according to the weather change

Because the temperature will affect the tolerance of the root system to the fertilizer concentration, the fertilization concentration should be low when the air temperature is high, otherwise root burning will occur easily, and the concentration will be higher when the temperature is low. Therefore, fertilization should be applied according to weather changes.

4. Different fertilization methods are adopted according to different types of fertilizers.

When topdressing chemical fertilizer, ditch application should be adopted in order to concentrate fertilizer effect, cover soil in time after topdressing, prevent nutrient volatilization and reduce fertilizer efficiency, and nitrogen fertilizer should be more than 10 cm away from plant rhizome to avoid root burning. Topdressing combined with irrigation can improve fertilizer efficiency.

Winter cucumber planting is a kind of out-of-season planting technique. If you want to get high yield and high quality, you must master the technology well.
