Varieties should be selected from the 4th and 7th of the cucumber research series of cucumbers, and Beijing thorny cucumbers, Jiamusi green thorns, and Taiyuan black-wobblers.
In the rainy season when the nursery and nursery period is still at a relatively high temperature and strong light, it is necessary to choose a dry plot for the sorghum, a shade shed on the seedbed and equipped with rain-proof facilities. Seedlings can be filled with nutritive soil sowing and nursery using paper tubes (bags) or plastic cups to protect the roots and promote seedling growth. Cultivation of seedlings can reach maturity of about 25 days. Each greenhouse is made up of 3 high-altitude sorghums, 1 meter apart, 40 centimeters wide and 16 to 20 centimeters high, with three walkways in the south, north and middle. 60 plants were planted in each greenhouse. Management enters the vegetative growth stage (planting to the formation of root melons), covers the agricultural film, strengthens ventilation, and strictly controls humidity. Into the guacamole stage, it is necessary to heat the stove in a timely manner to cover the grass curtains in time and make full use of natural light to prevent chew. Look at the days of seeing seedlings, reasonable fertilizer management. Before the roots of melons are harvested, avoid flooding so as not to cause roots and leggy. At this time, seedlings are mainly used to control pods to prevent nutrient growth from being excessive and postponing sitting cucumbers. The top dressing time is to be properly grasped. It is too early to go crazy and miss the melon too late. In general, when the root melon grows to about 15 centimeters, when the loin is withdrawn, it is a good opportunity to top-dress. To manure, water alternately, a small number of applications, avoid the roots of dead fat seedlings. In the temperature management, planting to the seedling stage, during the day at room temperature to 25 °C, 20 °C to 22 °C at night is appropriate. Root melon growth during the day is suitable from 24 °C to 26 °C, 20 °C at night is appropriate. The temperature of fruiting melons can be appropriately increased. It is advisable to use 25 to 27°C during the day and about 22°C at night.
