What are the tips for managing greenhouse loofah?
Temperature regulation, loofah in the whole growth period must have a higher temperature and suitable light, suitable growth temperature of 20 °C ~ 24 °C, fruit development temperature of 24 °C ~ 28 °C. Loofah grows slowly at about 15°C, and growth is inhibited below 10°C. The temperature in the greenhouse during the day should be maintained at 25°C to 30°C, and the temperature at night should be maintained at about 18°C. Before pumping vines, the sunshine duration should be appropriately controlled to promote stem and leaf growth and female flower differentiation. Flowering and melon period, make full use of sunlight to increase temperature and promote flowering and sitting melon.
Watering at the right time, the water requirement of the loofah at the seedling stage is small, and the small water can be poured in 1 to 2 times depending on the situation. When the loofah grows about 5 centimeters long, combined with earth, topdressing potassium dihydrogen phosphate + plant electronic fertilizer, pouring water once. In flowering and squashing stage, water is usually poured once every 7 to 8 days. At the same time, potassium dihydrogen phosphate and plant electronic fertilizer must be topdressed.
Stretch the vine, when the loofah grows 25 centimeters or so, it needs to be taken. In order to reduce the space occupied by the poles and shade, wire ropes or nylon ropes are generally used to fasten the brackets on the greenhouse to form a single row of vertical racks. The tops do not cross, and the original row spacing and density are vertically directed upwards. Loofah vines, after every 4 to 5 leaves tied once, can be used S-shaped binding method. At the same time, attention must be paid in time.
Promote fruit setting. It is reported that spraying Zhuanggutiling + new high fat film before flowering of loofah can activate the positive energy of plant ecological growth, broaden the route of plant pipes, increase the water absorption capacity of plants, increase the yield and quality of fruits, reduce the fruit drop rate, and reduce cracking and freezing. Fruit, malformed fruit incidence.
Pest Control. The main diseases of loofah include anthracnose and epidemic diseases, and can be controlled by carbendazim, chlorothalonil, polymyxin, and the like. The pests mainly include guava and whitefly, etc., and can be used for prevention and treatment of fish rattan, fluocin and so on. According to reports, the use of new high-fat lipid membranes at the time of application can increase fertilizer efficiency, reduce the amount of drugs used, and reduce pesticide residues.
