Abstract: Yue Cucumber 1 is suitable for greenhouse cultivation and greenhouse cultivation in early spring. In the middle and lower reaches of the Yangtze River, the seedlings are raised in an electric hotbed in late February, planted in mid-March, and harvested in mid-to-late April. In the early spring greenhouse and greenhouse cultivation, the use of its supporting cultivation techniques can promote early maturity, increase early yield, increase output value, and mention the morning market for good economic benefits. Yue Cucumber No. 1 is a new cucumber variety studied by Yueyang City Institute of Agricultural Sciences. The varieties showed early maturation, about 50 days from sowing to harvesting, and 95 days of the whole growth period; strong females, dominating melons on the main side, 1 to 3 female flowers per section, 80% or more of the female plants, self-flowered Strong melon ability; strong plant resistance: strong plant growth under low temperature and low light conditions, resistance to downy mildew, powdery mildew, wilt and other diseases; good taste good quality: melon rod-shaped, dark green, aneurysm medium, melon Straight, melon flesh white, about 30cm melon length, single melon weight about 250g, fruit diameter 3.6cm, fruit heart diameter 1.6cm, melon crisp, sweet, no bitter taste; previous production and total output outstanding, commodity melon High rate, high yield, average 7500kg/667.0m2, storage and transportation, good merchandise. Suitable for early spring greenhouse and greenhouse cultivation in the middle and lower reaches of the Yangtze River. In order to bring into play the characteristics of varieties, promote early maturing, and provide good economic benefits for the city, the following cultivation techniques are as follows: 1 Seedlings and seedlings before seedling preparation of 1.1 seedbeds: Preparation of mountain fine loess + decomposed organic fertilizer + compost wood + fine coal ash Mix evenly in the ratio of 2:1:1:0.5. Add compound fertilizer in a 1% ratio. After being piled up and poured with water, it was fermented for one week with a film cover and dried for use. Early spring seedbeds use electric hotbeds or in greenhouses. 1.2 Seeds are treated with hot water at 50-55°C for 20 minutes, stirred, and soaked in warm water of about 25°C for 3-4 hours. With a wet towel wrapped into the 32 °C incubator germination, 16-18 hours seed germination, shoot 0.2-0.5cm seeding. 1.3 Sowing early spring greenhouses, greenhouse cultivation cucumbers (not warming) sowing in late February or early March, seedling age about 20 days, seedling plate sowing, a seed per hole. About 3,500 acres of seedlings are planted, and the amount of acres required is between 90 and 100 grams. Seedlings filled with nutrient soil before sowing were soaked with 600-fold mancozeb solution. Plug the small holes with bamboo sticks, put the germinated seeds, cover a small amount of dry nutrient soil, cover with film after sowing. 1.4 In the first three days of seedling management, the temperature of the electrothermal hotbed is controlled to be at least 15°C during the night and about 30°C during the day. After unearthed seedlings, the seedlings turned to 12°C at night and 30°C during the day. Humidity control in the seedlings is not appropriate white soil, seedlings to prevent high temperature and high humidity appear high seedlings, burn seedlings, too low temperature (below 8 °C), emergence of frozen seedlings, frost damage. During sunny days, it is necessary to remove the film and cool down in time, and prevent the early spring frost at night. Long-term rainy days should be properly filled with light measures. The seedlings can be transplanted with one leaf. 2 The site preparation site for basal fertilization should be warmed up by one month before planting. Use narrow row cultivation. Press 畦 width 90cm, groove width 40cm, open the soil preparation, hoeing to deep plowing, combined with soil preparation per acre into the cooked rot of farmyard fertilizer 5000kg, three days of compound fertilizer 50kg as a base fertilizer, after the ground is completed, water drenched, two days later Plastic film spare. 3 The planting temperature is stable above 12°C and the temperature above 10°C is based on planting. General greenhouses are planted in mid-March. In early spring before and after the Ching Ming period, the vegetation in the open area of ​​Yueyang area should take into consideration the “March 3†storm. Planting seedlings should be selected before noon on the sunny planting, according to the width of 90cm planting two rows, spacing 35 to 40cm, required to open holes on the film to plant seedlings, pay attention to the size of the membrane mouth, 2cm away from the seedling stem is appropriate. After planting the seedlings, the water is poured into the water at about 20°C with 600 times mancozeb manganese dioxide and 600 times the enemy to kill the liquid. Shoe shed insulation, high temperature within the shed is not more than 35 °C is appropriate. 4 Management 4.1 Temperature Management The main problem after cucumber colonization is how to increase the temperature. The most effective way is to increase the temperature in the shed. Generally, the temperature in the shed during the sunny days reaches 35°C to 38%°C. The film is not lifted, and then released after a few days. Another focus of temperature management after planting is protection against freezing and freezing. The daylight temperature in the shed can generally meet the requirements, but due to the poor insulation of the plastic film at night, the temperature in the shed can only be 2°C higher than the open space. From mid-February to mid-to-late March, due to the low temperature in early spring, cucumbers are often chilled and chilled. On sunny days, when the temperature in the shed rises to 32°C, ventilation is started; at noon, it maintains a high temperature of 1 to 2 hours, ie, 30° C. or more, to reduce the air temperature and promote strong growth; in the afternoon, when the temperature in the shed drops to 20° C., the shed is closed. Film insulation; the minimum temperature in the night shed is 12 °C. Overcast and rainy days, attention should be paid to keeping the nursery warm. In mid-April, do cover the windows slightly, and moderately ventilate on cloudy days. During the sunny days, the temperature should be controlled to be low. When it reaches 30°C, it should be ventilated. With the increase of temperature, the ventilation window should be gradually increased. Indoor air temperature 25 °C ~ 30 °C is the best photosynthetic temperature, during the day should try to extend the best photosynthetic temperature time, reduce respiratory consumption, close the film of the film gradually pushed back until sunset. In late April, when the temperature stabilizes above 15°C, the windows can be uncovered, ventilation can be strengthened, and the seedlings can flourish. 4.2 Fertilizer management mainly depends on artificial watering in the greenhouse. When transplanting (planting), pour water once, and the amount of water should be small. The wet soil shall prevail. After 5 days of colonization, combined with watering, apply low-level decomposed organic fertilizer water to promote seedling growth. Into the pumping period, should control the fertilizer and water, dry soil is appropriate to prevent stems and leaves lengthy. After entering the flowering and fruiting period, break the membrane and top-dressing, collect 1-2 times for each harvest, apply 1 to 20% to 30% of manure water (appropriately add some compound fertilizer) as “strong fruit fertilizerâ€. Diligent fertilizer, a small number of times, to ensure fertilizer and water supply. 4.3 When cucumbers are grown in the vine-raising stage, the cucumbers grow rapidly. They should be strung and hung in time. The bamboo poles can be used to hold the trusses. You can also use the greenhouse frame to hang the vines with plastic ropes. One rod or one string can be used. vine. After the cucumber is put on the shelf, it grows very quickly. It is necessary to tie the head and introduce the vine in time, but it does not make a bend and it is beneficial to straighten the melon. General requirements of 2 to 3 days of rattan, sunny afternoon, moderate elasticity, until the bar above, then let it climb, appropriate lead. 4.4 Techniques Shuguoyue Cucumber No. 1 is mainly dominated by vine-bearing melons. The ability of lateral vines is strong. The plants have 1 to 2 melons per section. In order to improve the quality of the melons, the fruit should be timely squaring and fruit cutting. The female flowers below 3 nodes should be completely removed. The bottom lateral branches were all removed and entered the late melon stage. After removal of the main vine shoot tips, the basal part can be left to turn back to the flower seat melon, and the base branches back to leave 2 melons and 2 leaves to pick the heart. 4.5 Pay attention to prevent pests and diseases, avoid continuous disease prevention, and control diseases such as downy mildew, powdery mildew, and wilt disease from the seedling stage every 5 to 7 days to spray and control MdZn and carbendazim 600 times; pests Can be used to kill, eliminate and other high-efficiency and low toxicity pesticides. Avoid continuous cropping, and plots planted with melon crops must be rotated for more than two years. 5 The timely harvest of Yue Cucumber 1 usually blooms about 27 days after planting. The female flower can be harvested about 5 days after it is opened. Since this species can hold 1 to 2 melons per section, the continuous seat is strong and the bottom cucumber should be as early as possible. Harvested to promote plant and upper fruit growth. Increase early production and increase output value. The cucumber in the greenhouse in Yueyang region was harvested around April 22, with a market price of 3.6 yuan/kg and considerable economic benefits.
