Shandong Agricultural supply quality grafted cucumber seedling breeding base technology

Products grafted cucumber grafted on how to manage the level of graft survival rate after management has a very important relationship. Cucumber Grafted management focus is: to create the appropriate temperature, humidity, light and ventilation conditions are grafted, accelerate healing interface and grafting seedling growth. Product Attributes (1) suitable temperature for grafted wound healing is about 25 ℃, the interface is slow to heal at low temperatures, affect the survival rate. (2) If the grafting seedbed moisture air relative humidity is relatively low, scion easily cause dehydration wilting, it will seriously affect the survival rate of grafted seedlings. 3 to 5 days after grafting, a small shed in the air relative humidity at 85% to 95%. (3) The blackout in Pengwai coverage sparse reed screens or shade net, avoid direct sunlight and cause scion seedling wilting, night also from the insulation. (4) 3 to 5 days after grafting ventilation when grafted seedlings begin to grow can start ventilation. Small vents to start, and then gradually increase. (5) to quit by abutting law scion grafted cucumber seedlings grafted seedlings planted in 10 days, it can give scion root pruning. Methods of food eaten raw, fried food, eating and other eating salad. Why the growth characteristics in the greenhouse cultivation of cucumber seedlings say is the basis of the formation of cucumber yield in cucumber cultivation in the greenhouse, greenhouse structure can achieve high performance and corresponding supporting technologies. In the supporting technology, the nursery is the key determinant of the level of cucumber production. This is mainly because most of the flower buds are in cucumber seedling differentiation and form. Floral sexual type is plastic, the main factor is the impact of the type of temperature, light, water and nutrient conditions; in cucumber cultivation in the greenhouse, control the temperature during the nursery lighting conditions, the reasonable control of sunshine hours, adjusting temperature during the day and night, and promote the formation of female flowers; and lay a good foundation for the high-yield harvest. Grafted cucumber seedling age nutritional value to what is appropriate greenhouse grafted cucumber seedling age should not be too long, or too hurt the roots when planting, likely to cause premature aging plants. The experience of recent years by high-yielding look, whether it is self-rooted, or grafted seedlings, seedling age is not too long. Suitable seedling age were 30 - 35 days is appropriate, their fertility index is 3 leaves a heart. Practice has proved that when the cucumber planting, seedling age the smaller, the better production efficiency. Economic value in the greenhouse cucumber cultivation, control the temperature light conditions, the reasonable control of sunshine hours, adjust the temperature during the day and night, promoting the formation of the female during breeding; high-yield harvest lay a good foundation. Spring Cucumber seedling production and use of cryogenic Why cucumber seeds cold treatment in order to enhance seedling cold tolerance, the specific method is to have a period of immersion swollen seed germination, germ will To germinate, low-temperature process, put 0 ℃ low temperature around freezing for 1-2 days, some on a -2 -5 ℃ place, be 2-5 hours of treatment, no device can be placed in snow conditions during and after the process slow freezing in cold water, then It is primed. Low temperature, low temperature capability can enhance seedling, to produce low-temperature characteristics of adaptation. Most other explanation cucumber flower buds are formed in the seedling stage differentiation. Floral sexual type is plastic, the main factor is the impact of the type of temperature, light, water and nutrient conditions; in cucumber cultivation in the greenhouse, control the temperature during the nursery lighting conditions, the reasonable control of sunshine hours, adjusting temperature during the day and night, and promote the formation of female flowers; and lay a good foundation for the high-yield harvest.
