1, nurturing strong seedlings 1 soak germination. Sowing before planting 1-2 days, and then soaking with 55 °C warm soup for 15-20 minutes, natural cooling and then soaking in fresh water for 4-5 hours, remove, wrapped with gauze, put in germination box, at 28 °C temperature Germinate, check 2 times a day, rinse the seeds with lukewarm water and wait until the seeds are white. The open field cultivation can be directly sowed without germination, but in the emergence, it is necessary to break the membrane to help the seedlings in time. Use 200 grams per acre. 2 Make a seedbed. Seedlings can be nursed by electric heating lines, multi-layered heat preservation seedlings, and containers such as nutrient cartridges or plastic cylinders, straight through 10 cm. Seeding earlier, the temperature is low, the use of electric wire nursery, arranged above the nutrition, with the sowing date delayed, can be used cold bed nursery. Top soil of rice fields with high fertility or 6% of garden soil that has not been cultivated for more than 3 years, 3 parts of decomposed manure, 1 part of coke ash, plus 0.2% of ternary compound fertilizer, mix well, and spray 20 The soil of 1000% methyl-rhapont-alcohol EC was disinfected, screened and mounted. 3 seeding management. The germinating seeds were placed on a flat surface in a nutrient bowl, with 1 tablet per bowl. After sowing, they were covered with 1 cm thick nutrient soil, and then the plastic film was flattened and incubated. When about 70% of the seed cotyledons were unearthed, the flat cover film was removed and the heat preservation was continued. From sowing to cotyledon unearthing, the soil temperature is maintained at 25-30 °C. After the cotyledon is unearthed, the soil temperature is 20-25°C during the day and 15-20°C at night. After the first true leaf is unfolded, try to shine as much as possible and less water to prevent crowding of seedlings. 5-7 days before transplanting, strengthen the hardening of seedlings to adapt to the external environment. 2, colonization of a basal fat. Per acre applied mature yam 3 000 kg, ternary compound fertilizer 50 kg, combined with site preparation, ditch application. 2 for you. Cultivated on the ground, a 60-cm walkway is left in the middle of the shed, 1.2-meter-wide walks are made on both sides, droppers and mulches are laid, and a small arch shed is affixed to the west side of the shed. A space of about 1.5 meters wide is used for creeping. The scaffolding was cultivated to create a 1.2-meter-wide coffin and a 60-cm wide walkway. The open field cultivation can be made into a 2.5-3.0-meter-wide bract, planting rows covered with plastic film. 3 density. When the melon seedlings have 3 true leaves, they can be planted. Cultivated on the ground, each standard greenhouse (30 meters long and 6 meters wide) is planted with about 200 plants. The scaffolding cultivation, planting 2 rows per plant, plant spacing 45-50 cm, about 350 per shed. In open field cultivation, the plant spacing is 40-45 cm and 500-600 plants are planted per acre. Climbing planting. 3, field management 1 temperature management. Within 7 days after colonization, small arch shelters were used for closed management to increase temperature and promote seedling easing. After easing the seedlings, keep it at 25-28°C during the day and 15-18°C at night. When the temperature exceeds 32°C, it should be ventilated and cooled. 2 fertilizer and water management. When planting, the root fertilizer was poured with 1% urea solution. Early control of nitrogen is not top-dressing, and stem-leaves are very long. Wait until the head of the melon settled and then topdressing, each greenhouse topdressing urea and ternary compound fertilizer each 5-7 kg. After the head melon was harvested, topdressing urea and ternary compound fertilizer were each 5 kilograms, and the topsoil was then top-dressed as if it were plant growth and larvae. Exploit cultivation, nitrogen control, after the melon, per acre topdressing 10-15 kilograms of urea, potassium chloride 10-15 kilograms, 10-15 days after the top 10 kilograms of urea, chasing 2 times. In the fruit enlargement period, the water demand is large, timely irrigation, appropriate ventilation after irrigation, reduce the air humidity in the shed, irrigation is best to use drip irrigation. 3 timely scaffolding. When the plants have 6-7 true leaves, they should use small bamboo poles to set up the brackets, slightly lower than the height of the greenhouse, take the "person" shaped frame, the lower horizontal tied 1-2 layers of bamboo poles. 4 whole vinegar. The main vines are mainly guarana, when the vine is 50 centimeters in length, it is necessary to timely introduce the vines, bind the vines, and press the vines so that the vines are evenly distributed on the plane or on the ground. Thereafter, the vines are distributed in batches every 5 to 7 days. And timely removal of lateral branches, old leaves, diseased leaves, in order to facilitate ventilation. 5 promote fruit setting. Female flowers appear in sections 6-8. In order to maintain the balance between reproductive growth and nutrient growth, pollen of female flowers opened before and after 10 knots is pollinated and set aside. Due to the low temperature and early illumination of greenhouses, insects are less active and the amount of pollen is less. Artificial pollination is needed. The corolla of the male flower is removed around 8:00 am and the pollen on the stamen is applied to the head of the female stigma. A male flower can grant 2-3 female flowers. In the early spring, there will be only female flowers, no male flowers, or male flowers, but the phenomenon of low pollen viability can be used to pollinate the male flowers of the zucchini, or to promote the results with 40 mg/liter of versicolor. 4, about 15 days after flowering, when the skin color becomes dark green, the tender melon can be picked; 25-30 days after flowering, the old ripe melon is harvested. Picking on sunny morning.
