Cucumber in order to overcome and prevent the formation of bitter elements, mainly master the following four points. 1) temperature. Photosynthetic optimum temperature for cucumbers 25 ~ 32 ℃, in production, when the studio room temperature reaches 25 ℃ start ventilation Cucumber supply market, as temperatures rise should gradually increase ventilation. Ventilation should be open in early spring against the wind, to avoid the open end of the wind, the wind caused the door sweep to prevent cold cold root seedlings, which cuts. 2) humidity. Cucumber like wet fear of drought. General requirements for soil moisture of 60% -70%, 80% air humidity during the day, at night 90%. If the soil humidity reaches 60% -70% in production, pay attention to ventilation, while fresh vegetable supply base to increase the content of carbon dioxide, on the other hand can reduce indoor humidity, to avoid the formation of a water film on the foliage and light refraction which led to bitter elements increases. 3) illumination. Cucumber light compensation point where cucumber 10,000 lux best below 10,000 lux, even if the temperature suitable aloesin concentrations rise. So in early spring production management, fill light is as important as controlling temperature and humidity. Greenhouse hang reflective film is an effective way of credit. Cloudy films when no ice in the premise, to ensure the normal mortgage thatch cucumber, to increase the absorption of the scattered light. 4) fertilizer. Adjustable rational fertilization cucumber plant physiological basis, promote growth and development. How soaking cucumber seed germination? Soaking Seed soaking in seed disinfection basis. The specific method is to put the seeds in warm water to clean, the water temperature is generally 20-30 ℃, after 4-6 hours, when the seeds reached the fully inflated, drain off excess water, scrub clean, then primed. Cucumber germination germination in many ways, such as kang germination, flue germination. The scientific method is the use of temperature-controlled germination, seedling factory concentrated germination method is widely used, a small amount of seed germination, etc. can also be incubators.
