Varieties should be selected from the No. 4 and No. 7 of the Jinyan series of cucumbers, as well as Beijing thorn melon, Jiamusi thorn and Taiyuan Hewo snake. During the seedling nursery period, it is still in the rainy season with higher temperature and stronger light. It is necessary to choose dry land for sorghum, and the seedbed is equipped with a shade shed and equipped with rainproof facilities. The seedling method can be put into the nutrient soil by paper tube (bag) or plastic cup to sow seedlings to protect the roots and promote seedling growth. The seedlings can be planted for about 25 days. Each greenhouse is made up of 3 stilts, with a row spacing of 1 meter, a raft width of 40 centimeters, and a height of 16 to 20 centimeters, corresponding to three south, north and middle walkways. 60 plants were planted in each greenhouse. Management enters the vegetative growth stage (planted to root melon formation), the roof covers the agricultural film, strengthens ventilation, and strictly controls humidity. In the stage of entering the knot, it is necessary to heat the stove in time, uncover the grass curtain in time, and make full use of natural light to prevent the melon. Look at the sky to see the seedlings, and rationally manage the fertilizer and water. Before the roots are harvested, avoid pouring large water to avoid causing roots and length. At this time, the seedlings are mainly controlled to prevent the growth of nutrients and delay the sitting. The time for topdressing should be properly controlled. It’s too early to go crazy, and it’s too late to miss melon. In general, when the root melon grows to about 15 cm, the waist melon is a good opportunity to topdress. It is necessary to alternate the manure water and the clean water, and apply it in small amounts several times. In the temperature management, planting to the seedling stage, the room temperature is preferably 25 ° C during the day and 20 ° C to 22 ° C during the night. The growth period of root melon is 24 ° C to 26 ° C during the day and 20 ° C at night. The temperature at the peak of the seasoning can be appropriately increased, preferably 25 to 27 ° C during the day and 22 ° C at night.
One-button flash tester, also known as One-button fast measuring instrument and One-button fast image measuring instrument, is widely used in the measurement and detection of die-cutting products, mobile phone cover plate, mobile phone glass, PCB, spring, screw, precision hardware, machined parts and other products. Once used, the one-button flash tester does not need a fixture, and the product can be placed arbitrarily. The full-size measurement of the product can be completed with one button, with high efficiency, high accuracy and simple operation.
