First, adjust the temperature and light. The loofah has a higher temperature throughout the growth period, the suitable temperature for growth is 20 Â° C ~ 24 Â° C, and the suitable temperature for fruit development is 24 Â° C ~ 28 Â° C. The loofah grows slowly at around 15 Â°C, and the growth is inhibited below 10 Â°C. In the management, the temperature in the greenhouse should be maintained at 25 Â° C ~ 30 Â° C during the day, and the night temperature is maintained at around 18 Â° C. Before the gourd is vine, the grass can be used to properly control the sunshine time to promote stem and leaf growth and female flower differentiation. In the period of flowering and meloning of loofah, it is necessary to open the haystack in due course and make full use of the sunlight to raise the temperature to facilitate the flowering of the melon.
Second, timely watering and topdressing. The water requirement of the loofah seedlings is not large, and it is possible to pour small water 1 or 2 times in a timely manner. When the loofah is about 5 cm long, combine with the soil, apply 30 kg of potassium dihydrogen phosphate per acre, and pour the water once. The loofah flowering and meloning period is in mid-May, and the temperature is high. Generally, water is poured once every 7-8 days, and 5 kg of urea is applied per acre.
Third, the frame tied to the vine, plant adjustment. The loofah vine can be up to 8 meters long, and it needs to be framed when the vine is about 25 centimeters long. In order to reduce the space occupied by the poles and the sunshade, it is generally directly attached to the greenhouse bracket by wire or nylon rope, so that it forms a single-row vertical frame, the top does not cross, and the vines are vertically oriented according to the original planting row spacing and density. After the loofah vine is put on the shelf, each 4 to 5 leaves are tied once, and the S-shaped binding method can be used. At the same time, pay attention to the timely fall. Since the loofah itself is more resistant to disease, the leaves on the vines do not have to be removed.
Fourth, the flower and fruit. Using 2,4-D, anti-fallin, and loofah Shunzhi's compound liquid, the flower can reduce the flower drop and significantly increase the sitting rate. Generally, the flowers are directly rubbed in the liquid medicine, so that the top of the mature loofah will also carry fresh flowers, and the commodity value is high. The work of silk flowers should be carried out around 8 am.
5. Pest control. The main diseases of loofah are anthracnose, epidemic disease, gray mold, and can be controlled by pesticides such as carbendazim, chlorothalonil and polymyxin. The pests mainly include melons and white meal, and can be controlled by the fish vine essence and the cockroach.
