1 , nursery. For the cultivation of spring sorghum and autumn and winter sorghum, it is best to use grafting seedlings. Time for nursery early to late April, autumn-winter season is 10 months late. It is suitable for greenhouse cultivation with good lighting, good heat preservation and minimum winter temperature of not less than 8 °C.
2 , colonization. 8 to 10 cubic meters of decomposed chicken manure, 50 to 80 kilograms of diammonium, or 80 to 100 kilograms of ternary compound fertilizer. Do small stilts, 畦 wide 70 ~ 80 cm, walkway width 60 ~ 70 cm, choose sunny day morning ridge dig acupuncture and colonization, the hole distance 30 cm, dense in front of the shed, the land is rare and planted 3000 acres. Pour enough water and cultivate three or four times. The root is laid down and the mulch is laid.
3 , temperature management. After planting, keep the shed temperature between 28 °C and 32 °C during the day and above 20 °C during the night. After the seedlings are warmed, the shed temperature is 25 °C ~ 27 °C during the day, 15 °C ~ 20 °C during the night, and the temperature starts to exceed 30 °C.
4 , water and fertilizer management. When planting, pour enough water. When the root melon grows to about 10 cm, water it again and remove the cucumber below 5 knots. In the first melon period, water is poured for 3 to 5 days, two waters and one fertilizer, and nitrogen, phosphorus and potassium are combined. Water is poured once every 10 to 15 days in the harsh winter. When the temperature rises, water is poured in four or five days. Sheng Guaqi fertilizer Mushi 20 to 30 kg, 20 kg of urea plus. Foliar spray of 0.3% potassium dihydrogen phosphate or sugar nitrogen vinegar solution to prevent disease. 7 days 1, with 3 to 5 times. Formula of sugar nitrogen vinegar solution: sugar 50 ~ 100 grams, urea 50 ~ 75 grams, vinegar 35 ~ 50 grams, 90% ethyl phosphorus 10 ~ 15 grams, 50 kg of water.
5 , lighting management. Hang the reflective curtain on the back wall, clean the dust on the shed, and remove the droplets on the membrane in time. The grass is covered on a sunny day, and it is appropriate to cover the grass in the evening to open the grass. Pay special attention to the sudden turn of the weather after a few days, and the plants must be sprayed with water to cover the shade. Ventilation when the temperature exceeds 30 °C, can supplement carbon dioxide gas fertilizer to improve quality and disease resistance. Pay attention to pests and diseases.
6 , plant adjustment. When the cockroach grows to 30 to 40 cm, hang the vines in time, remove the wheat and male flowers, remove the old yellow leaves and diseased leaves, and timely smash the stalks to protect 13 to 15 functional leaves.
7 , harvesting. In autumn and winter, cucumbers are harvested and planted with tender melons. When the growth is weak, they should be harvested early. When the growth is strong, they can be harvested late. After the temperature is lowered, it should be lightly harvested and extended after harvesting. Due to the low temperature and short sunshine time in the growing season, the cucumbers in autumn and winter use the differentiation of female flowers, and should be harvested as early as possible, and appropriate flower thinning and fruit thinning.
