Greenhouse cucumber cultivation techniques
First, choose the appropriate variety from the practice in various places in recent years, we should choose the varieties of Jin research series of cucumber No. 4 and 7, and the Beijing thorns, Jiamusi green thorns and Tai Wo black snake and other varieties. Second, timely nursery should choose dry plots for sorghum, sit on the seedbed shade shed and equipped with rain facilities, guard against rain. Third, the nursery method can be used paper Tube (bag) or plastic cups into nutritious soil planting seedlings, in order to protect the roots to stabilize the root, and promote seedling growth. Cultivation of seedlings can reach maturity of about 25 days. Each greenhouse is made of three high-altitude plants, with a 1-meter spacing, a 40-cm width, and a 16-cm to 20-cm height, with three walkways in the south, north, and middle, and 60 in each greenhouse. Fourth, management measures entered the vegetative growth stage (planting to the formation of root melons), the roof covered with plastic sheeting, enhanced ventilation, and strict control of 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. Secondly, the top dressing time must 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 In general, when the root melon grows to about 15 centimeters, when the loin is withdrawn, it is a good opportunity to top-dress.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 addition, in the temperature management, planting to the seedling stage, during the day at room temperature to 25 °C is appropriate, at night with 20 °C ~ 22 °C is appropriate; root melon growth period during the day is 24 °C ~ 26 °C is appropriate, at night, 20 °C is appropriate; Melon peak temperature can be properly increased during the day to 25 °C ~ 27 °C is appropriate, at night about 22 °C is appropriate.
