Cucumber cultivation process is mainly "select seedlings - seedlings - soil preparation - fertilization - planting - frame introduction vine - fertilizer and water management - pest control" and other links.
1. Variety selection. The spring facilities for nursery, open field cultivation should use Jinchun 4, 5, Jinyou 4,6, Tianjin Green 4,6, Zhongnong 6,8; or Xiangyuan 3,1, Xiangchun 3,4, etc. Variety. The spring facilities facilitate cultivation and selection. Zhongnong 9,12,7, Jinchun 1,2, Jinza 2,4; or Xiangyuan 3,1, Xiangchun 3, Chunyuan 4, and other varieties.
2. Sowing seedlings. The open-field cultivation is planted from mid-March to late April, with electric or cold bed nursery. The facility facilitates cultivation of seeds from mid-January to mid-February, with electric heating. The amount of mu for use is 150 grams.
Seeds soaked with warm scalding for 15 minutes before sowing, washed and dried, germination or direct seeding. Keep the soil temperature at about 28°C and emerge from 4 to 5 days. It is recommended to use a nursery to grow seedlings. After the cotyledon is unfolded, the seedbed is planted on a seedbed at a spacing of 1010 cm. Seedbed temperature during the day 18 ~ 28 °C, at night not less than 12 °C is appropriate, when the seedlings 1 leaf 1 heart, topdressing a 10% concentration of slag to faecal water; 2 leaf 1 heart, spray once 0.1 ~ 0.2% Potassium dihydrogen phosphate solution, followed by a 20% concentration of dregs. 6 to 7 days before transplanting, pay attention to hardening the seedlings.
3. Whole soil fertilization. Guadi is not continuous cropping, choosing land that is easy to transport and has good irrigation and drainage conditions. When cultivated land, Mushi lime 100 kg, the whole soil, Mu Shi manure 2000 to 3000 kg, compound fertilizer 60 kg. Spray 600 times enemy liquid to reduce the disease. The mask can be warmed by the film.
4. Colonization. Ground cover and open-field cultivation Transplantation from early April to late April; facilities to facilitate cultivation before mid-March transplanting. About 3,500 per acre, pour water after planting.
5. Cultivation management.
(1) Facilities adjustment. In March, the temperature was extremely unstable, hail occasionally occurred, and the facility adjusted attention to heat preservation and protection of seedlings to control water and prevent freezing. In April, the temperature quickly picked up. Occasional cold air cooling and hail occurred, and precautions were taken. The cultivation of facility cultivation was opened early in the morning and closed late, keeping the seedlings strong. When the local temperature stabilizes above 10°C, it can be removed from the shelter.
(2) scaffolding vines. When the vine grows 0.3 meters, it starts to transplant, piles, and vines. After the scaffolding, Zato was introduced in a timely manner, and the vines were detached for 2 to 3 days at a time. After the sunny afternoon, the horizontal bar took up its climbing. In order to increase the early fruit setting rate of cucumber, 1:50 times of cucumber can be used early to spray stamen or stalk.
(3) fertilizer and water management. The spring cucumber plant grows fast and has many fruit-bearing fruits. It needs to supply fertilizer and water evenly and continuously. During the vegetative growth period, topdressing fertilizer was applied 3 times with 20% concentration of manure. Harvesting period, each harvest 2 times, chase a 3% concentration of strong fruit fertilizer. Use 0.2% potassium dihydrogen phosphate for foliar dressing 1 or 2 times to delay the aging of functional leaves.
(4) Prevention and control of pests and diseases. Before the five-leaf stage, 80% trichlorfon was used to prevent and treat Huang Shougua. After colonization and survival, it was immersed in water with a 600-fold solution of watermelon scorpion to prevent soil-borne diseases such as blight. The wettable powder 400 times spraying leaves 3 to 4 times, can effectively inhibit the downy mildew disease.
(5) Harvesting. Facilities for cultivation are generally harvested from late April to early May; ground cover and open field cultivation are available in mid-May and mid-May. Harvesting interval, the first 2 to 3 days 1 time, 1 to 2 days in the middle and late.
