Banana zucchini, also known as golden skin zucchini, is native to Korea. The species is precocious, strong growth potential, the main vines, melons, vines up to 1m, fruit set rate is high, the results of a single plant can reach more than 10, 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 long, 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 667 square meters reached 4000kg. Its main cultivation techniques are as follows:
First, build organic soilless cultivation facilities
Use sunlight 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 1 kg of organic soilless cultivation special fertilizer to 1 cubic meter of substrate, and disinfect chicken manure by 10 kg. Mix and fill the trough.
In the greenhouse, a 2 m3 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 placed in the tank, and a thin film is overlaid to prevent drip irrigation from spraying.
Second, soilless grafting seedlings
1. Germination sowing: In the region in early October, banana zucchini and black seed squash were soaked and germinated at the same time. Use plug-hole soilless seedlings, according to peat: vermiculite is 2:1 with a good nursery substrate, 1 cubic meter of matrix by adding 5kg of disinfectant chicken manure and 0.5kg of vermiculite compound, mix and fill in the 50 hole 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 kept at 28?30?, after the emergence of cooling, keep 20? 25? during the day and 12? 15?
2. Grafting seedlings: rootstocks and scion seedlings leaves can be grafted after grafting, grafted seedlings into the 10cm10cm nutrition bowl (matrix preparation with the same plug tray), pouring water inside the pot, plug the arch cover film, shading moisture, relative humidity 90 About %, the temperature is 25-28°C during the day and 18°C ​​at night. Gradually seeing light after 3 days, removing the cover 5 days later, the grafted seedlings healed well after 10 days. Radon temperature 20-25 °C, night temperature 12-15 °C, keep the substrate moist. About 30 days, the seedlings can be colonized with 3 leaves and 1 heart.
Third, colonization
Before the planting, the substrates were leveled and leveled, and each cultivation tank was flooded with water to fully absorb the matrix. 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 is 45cm, 667 square meters colonizes 1500. After planting, lightly pour the roots of the substrate and the banana zucchini.
IV. Cultivation Management
1. Fertilizer management: 1 to 7 days after planting, 1 water to keep the substrate moist; the amount of water needed to increase after fruit set, sunny day, 1 water per day, every 20min. 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 carried out for 20 days after planting, and fertilizer was applied once every 10 days thereafter. Each time after each plant was chased with 10 g of special fertilizer, 25 g per plant was planted. Spread the fertilizer evenly 10cm away from the root, or 10cm from the root of the stem, bury the fertilizer in the matrix, and then water it. Carbon dioxide gas top dressing in winter and spring sheds can increase plant stress resistance and yield.
2. Temperature and light management: After planting, the temperature in the shed is maintained at 20-25°C during the day, 12°C at night, and the length of the seedlings is long. Warm up after fruit set, 25-28°C during the day and 12-15°C during the 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. Plant adjustment and pollination: The seedlings were erected when they were nectared with 8-9 leaves. 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, the male flowers are picked at the time of 6-9 in the morning for artificial pollination, or the female stigmas are smeared with 20-30 mg/kg of the falling kermis to increase the fruit setting rate.
V. Harvesting
It takes about 60 days to sow the cucumber zucchini until it is harvested. The melon grows to about 25cm, and when the melon stem is 3-4cm thick, it can be harvested and marketed. 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.
