The main technical point of management of greenhouse loofah
1, adjust the temperature and light. The optimum temperature for the development of loofah was 24°C-28°C, the temperature in the greenhouse was maintained at 25°C-30°C during the day and 18°C ​​at night. Before the loofah is pumped, the sunshine duration can be appropriately controlled by grasshoppers to promote stem and leaf growth and female flower differentiation. In the fruiting period of the flowering, open the grasshopper timely and make full use of sunlight to increase the temperature.
2, timely watering fertilizer. When the vine grows to about 5 centimeters, combined with re-cultivation, potassium dihydrogen phosphate top-dressing 30 kilograms per acre, pouring water once. After the flowering results, the water is usually poured 7-8 days, while topdressing 5 kg of urea per acre.
3. Arrange vines and plant adjustments. The length of stems of loofahs can reach 7-8 meters. When they reach 25 centimeters in length, they need to be racked. Generally, iron wire or nylon rope is directly tied to the greenhouse scaffold to form a single row of vertical racks, the tops do not cross, and the original planting spacing and density are vertically directed upwards. After vines are put on the shelves, the "S" shape binding method can be used once every 4-5 leaves are tied.
4, preserved fruit. The use of 2.4-4D paint can reduce flowering and significantly increase fruit setting rate. When the temperature is high, the concentration is 2010-6, and when the temperature is low, 3010-6 is used. It can be applied to the stigmas of the female flowers and the base of the corolla with a brush pen, and it can also be dip in the liquid directly. The application time should be around 8 am.
