1, environment selection
Cucumber belongs to crops that like warm environment and are not tolerant to ground temperature. Its suitable growth and development temperature is about 65438 08 ~ 32℃. When the temperature is lower than 10℃, it is easy to be frozen, which affects the growth and development. When the ground temperature is lower than 12℃, the growth of root system will be limited. Generally, the ground temperature is about 65438 05℃, which is beneficial to the growth and development of roots. Farmers can specify the transplanting time of cucumber according to this temperature regulation.
2. Soil preparation and fertilization
After the cucumber planting site is selected, a certain amount of organic fertilizer and organic fertilizer should be applied, and then balanced fertilization should be carried out. The most important chemical fertilizers are decomposed organic fertilizer, urea, calcium and potash fertilizer. To ensure the combination of chemical fertilizer and soil, farmers should pay attention to cultivating soil and make full preparations for planting.
3. Seed treatment
Cucumber cultivation technology should first treat the seeds, soak them in warm water at 25℃ for more than 6 hours, wash off the dirty substances on the surface, then pick them and cover them with a wet rag, put them in an environment at 25℃ to promote tooth growth, and pick them one day later to start planting.
Step 4 plant
Before planting, apply appropriate pesticides and fungicides to disinfect the land, furrow and ridge and irrigate it, then throw seedlings at effective intervals, seal the ditch with soil after seepage, plant 3500 plants on 1 mu, and tie a small arch shed on the border after planting.
5, transplanting cucumber seedlings
Seedlings can be transplanted when the ground temperature is kept at about 65438 05℃. Before transplanting seedlings, seedlings should undergo ultra-low temperature exercise for more than 10 days, and be transplanted in sunny morning or after 4 pm. Kakashi is the best transplanting time, so standardized management should be carried out to ensure the consistent emergence rate in the field.
