Suitable variety golden Cultivation Techniques 1. Nursery (1) soaking and germination: sowing seedlings in early October, soaking with warm water of 55°C before sowing and stirring continuously, soaking for 6-8 hours when the water temperature falls below 30°C, and then washing the mucous membrane on the seed coat with water, Remove and wrap it with gauze, and germinate it at 28～30°C. Seeds when 70% of the seeds are exposed. General cultivation of 667 square meters with 250 grams of seed, seedbed 25 square meters. (2) Preparation of seedbeds and sowing: 1 week before sowing, the whole seedbed is to be planted, and the seedlings are to be 1.2 to 1.4 meters wide. The nutrient soil is prepared in a ratio of 3:2 with soil and high-quality farmyard fertilizer. If nutritious earthworms are used to nurse the soil, they are placed on a nursery bed. Watering before sowing, each nutrition armored 1 to 2 seeds of germination, about 2 centimeters of cover soil, covered with plastic film, and then buckled a small shed to prevent rain seedlings. (3) Seedbed management: When the top seedlings of the seedlings remove the mulch, the temperature in the small arch sheds is maintained at 22-26°C during the day and at least 10-12°C during the night; when the seedlings have 3 to 4 true leaves, the daytime temperature is maintained 18- 22 °C, 8 ~ 10 °C at night, then gradually reduce the night temperature to 6 ~ 8 °C, hardening seedlings 5 ​​to 7 days, in order to improve the adaptability of seedlings. Seedlings were colonized at 4 leaves and 1 heart. 2. Colonization Site preparation: The cultivation of golden squash in greenhouses should be planted in wide and narrow rows, generally 1 meter wide and 60 cm in a narrow row. Before regrowth, 2000 kg of fertilizer for manure per 667 square meters, 50 kg of superphosphate. When smashing, another 100 kg of cake fat is applied to the bowl. Each row was planted in two rows and planted in a triangular pattern with a spacing of 50 cm. After planting, irrigating the water to promote seedlings. In order to increase the ground temperature, the mulch is covered with a mulch. If the planting is too late and the temperature is low, it can also cover the plastic film first, and then it can be planted after the temperature rises. 3. Post-planting management (1) Management of temperature and light: Close the greenhouse for 4 to 5 days after planting, raise the temperature, maintain 25 to 30°C during the day, and 18 to 20°C during the night to promote hair root easing. After easing the seedlings, the air is allowed to cool down during the day and the temperature is controlled at 20 to 25°C and 12 to 16°C at night to prevent leggy. Afterwards, the weather gradually turns cold and the daytime temperature is appropriately increased. During sunny days, the temperature can be controlled at 20-28°C during the day and 8-12°C at night to enhance the cold resistance of the plants. In case of snow, the grass is not revealed, but the snow should be cleared in time. After the snow, sunny days should gradually see light to prevent flash seedlings. After the spring of the following year, increase the temperature, keep the temperature during the day at 25 ~ 28 °C, night 8 ~ 12 °C, in order to facilitate the flowering results. The amount of ventilation was increased in the middle and late March, and the grasshoppers were removed in mid-April. The film was removed in mid-May. (2) Water and Fertilizer Management: After irrigating when planting, it is generally no longer watered before the first cucumber is sitting. When the first melon grows to 10 centimeters in length, it is poured with topdressing water and water is poured. Under the film, the fruit is poured under the film and the water is poured into the narrow row to control the humidity in the greenhouse. Usually about 15 days to pour water, you should master the principles of melons and watering flowers. After the temperature rises in the spring, according to the growth conditions, implement wide-narrow rows of watering, increase the amount of air after watering, and reduce the air humidity. As the basal fertilizer is relatively abundant, it is generally not top-dressing before squashing. After the melons are harvested, the melons are chased once per time, paying attention to the combination of nitrogen, phosphorus, and potassium fertilizers. In combination with disease prevention during the melon period, the leaves were sprayed with 0.3% potassium dihydrogen phosphate or other foliar fertilizers. (3) Flower protection and fruit protection: golden squash are pollinated by male and female crossbreeds, because there is no wind in the greenhouse, there is no insect activity, and the humidity is high, which affects the development of pollen, and it is easily pollinated and fertilized, resulting in fruit drop and fruit drop. Artificial pollination should be carried out to promote fruit setting. . Generally, male pollen is applied on the stigma of the female stigma before 10 o'clock in the morning, or with 60-80 mg/kg of anti-dropping agent applied between the base of the style and the base of the petal or on the young larvae. When adding liquid, it can add 0.1% quick-release to prevent the occurrence of gray mold. (4) Hanging vines: In order to allow the plants to fully receive sunlight and enhance photosynthesis, the vines will be erected to grow upright. That is to say, pull a north-south wire above the melon line, and use one rope for each quail. The lower part of the rope is fixed on the small raft. With the growth of the melon, the melon vine can be wound on the rope. Pay attention to timely pruning, removal of old leaves, tendrils, and lateral buds while hanging the vine. These operations are best performed at noon on sunny days to facilitate wound healing and prevent disease infestation. 4. reward When the melon grows to 20 cm long, it can be harvested. When harvesting, the plants that grow vigorously can be harvested properly. The plants that grow weakly and have many melon strips should be harvested as soon as possible; when the market price is high, the harvesting should be resumed, and when the price is low, the plants should be harvested properly.
