Banana zucchini, also known as golden skin zucchini, is native to Korea. The species is precocious, strong growth potential, the main vines melon, vines up to 1m; fruit set rate is high, the results of a single plant can reach 10 or more; high yield resistance. The fruit is banana-shaped, golden in skin color, and more crisp and juicy meat. It has excellent flavor, good commercial and ornamental qualities. The fruit is about 25cm in length, about 4cm in diameter, and about 250g in weight. Since the city introduced the variety in 2000 for greenhouse organic soilless cultivation, the output of 667m2 reached 4000kg. Its main cultivation techniques are as follows: First, the construction of organic soilless cultivation facilities using solar greenhouse cultivation. Bricks were used to establish a north-south cultivating trough with an inner diameter of 48 cm in the greenhouse, and the trough was 80 cm away from the wall as a walkway. The height of the groove frame is 24cm, the groove distance is 72cm, the base is covered with a film, the film is covered with 3cm clean river sand, and the sand is filled with the cultivation matrix. The matrix was prepared by sand: mushroom dregs: corn stover 1:2:2, and the wet film was sprayed and sterilized for 15 days. Add 2 kg of organic soilless cultivation special fertilizer to 1m3 matrix, disinfect chicken manure 10kg, and mix and fill the trough. In the greenhouse, a 2m3 reservoir was built and a corresponding drip irrigation system was built. The main drip irrigation pipe is made of plastic pipe, and 1 to 2 drip irrigation belts are laid in the tank, and a thin film is overlaid to prevent drip irrigation from spraying. Second, soilless grafting and nursery 1. Precipitate sowing in the region in early October, banana zucchini and black seed squash were soaked and germinated at the same time, the seeds exposed after sowing. Use plug-hole soilless seedlings, according to peat: vermiculite 2:1 with a good nursery substrate, 1m3 matrix by adding 5kg of sterilized chicken manure and 0.5kg of vermiculite compound, mix and fill in 50 holes plastic tray. After the seedlings were poured into the water, 1 seed was placed in each hole, and the vermiculite was covered with 1.5 cm. The pre-emergence temperature is maintained at 28-30°C, and the temperature is lowered after emergence. It is maintained at 20-25°C during the day and 12-15°C at night. 2. Grafting seedling rootstocks and scion seedlings leaves can be grafted after grafting, grafted seedlings into 10cm10cm nutrition pods (matrix preparation with the same plug tray), pod pouring water, plug the arch cover film, shading moisture, relative humidity About 90%, the temperature during the day 25 ~ 28 °C, 18 °C at night. Gradually seeing light after 3 days, removing the cover 5 days later, the grafted seedlings healed after about 10 days, and the scion cuts the roots. Alum temperature 20 ~ 25 °C, night temperature 12 ~ 15 °C, keeping the substrate moist. About 30 days, the seedlings can be colonized with 3 leaves and 1 heart. 3. Before the planting and colonization, the substrates shall be leveled and leveled, and each cultivation tank shall be flooded with water to make the matrix fully absorb water. After water infiltration, the banana squash were planted in two rows of pits per tank, and the substrate was slightly higher than the seedlings. Planting distance 45cm, 667m2 colonization of 1500. After planting, lightly pour the roots of the substrate and the banana zucchini. IV. Cultivation and Management 1. Fertilizer and Water Management After the planting, 7 to 10 days, 1 water is poured to keep the substrate moist. After the fruit is set, the water requirement is increased. In sunny days, pour water once a day for 20 minutes. Rainy and snowy days can be less or not poured depending on the specific conditions. The shed is often ventilated, gas exchange and air humidity reduction to reduce the incidence of disease. Colonization was performed for 20 days after planting, and then topdressing was performed once every 10 days. Each time, 10 g of special fertilizer was planted in each plant; 25 g of each plant was planted each time after fruit set. Spread the fertilizer evenly 10cm from the root, or 10cm from the rhizome to embed the fertilizer in the substrate and water it. CO2 gas top dressing in winter and spring sheds can increase plant resistance and yield. 2. After temperature and light management is planted, the temperature in the shed is maintained at 20 to 25°C during the day and 12°C at night. Warming after fruit set, 25 ~ 28 °C during the day and 12 ~ 15 °C at night. If the temperature is higher than 30 °C, it will easily form a physiological barrier, affect flower bud differentiation, resulting in the occurrence of high-temperature dehydration type mosaic and virus disease. The species is highly luminous, during the cultivation as long as the normal room temperature, but not to reduce the temperature, should be exposed as soon as possible to open the grass, as far as possible to see more light plants. Overcast and snowy days, strengthen management, as long as the exposing of the temperature of the rear shed does not drop too low, it should be announced early. Overcast and rainy days, it is not easy to expose the pods, which can easily lead to weak yellow seedlings, affecting yield, and the plants are susceptible to physiological wilting after the weather is fine. 3. When the plants adjusted and pollinated the seedlings with 8 to 9 leaves, the main vines grew upright. Timely removal of lateral buds, tendrils and sick old leaves to avoid consumption of nutrients and maintain the normal growth and results of the main vine. After the female flowers are opened, male flowers are collected at 6 to 9 in the morning for artificial pollination, or the female stigmas are applied with 20 to 30 mg/kg of vermilion to increase the fruit setting rate. 5. It takes about 60 days to harvest the harvested banana zucchini until it is harvested. The melon grows to about 25cm, and the melon stem can be harvested when it is 3 to 4cm thick. In the future, it is necessary to collect melons in time to avoid harvesting too late and cause melons to fall off and affect yield.
