Planting technique of towel gourd in greenhouse

Before planting, it is necessary to turn the soil and apply enough base fertilizer, then dig the planting ditch, then apply the base fertilizer, then close the ditch and ridge, wait until October, soak the seeds in warm water to accelerate germination, spread them evenly to the soil after germination, cover the soil and sprinkle water to let them sprout. When 1-2 true leaves are grown, they will be transplanted to the field according to the distance between the rows and plants. Finally, the basic management work such as water and fertilizer, pest control and so on can be done.

Key technical points of loofah shed management:

1. Adjust the temperature and light.

Towel gourd requires a higher temperature in the whole growth period, the growth temperature is 20-24 ℃, the suitable temperature for fruit development is 24-28 ℃, the growth is slow about 15 ℃, and the growth below 10 ℃ is inhibited. In the management, the temperature in the greenhouse is kept at 25-30 ℃ during the day and about 18 ℃ at night. Before the towel gourd is drawn, the sunshine time can be properly controlled by grass gourd to promote the growth of stems and leaves and the differentiation of female flowers. In the flowering and fruiting period, the grass should be opened at the right time and make full use of the sun to increase the temperature.

2. Watering and topdressing at the right time

Towel gourd seedling stage water demand is not large, depending on the soil moisture suitable for watering 1-2 times, when the vine grows to about 5 cm, combined with re-cultivation of soil, per mu topdressing 30 kg of potassium dihydrogen phosphate, watering once. After blooming and fruiting, water is usually watered once every 7-8 days, while 5 kg of urea is applied per mu.

3. Set up a frame and tie a vine

Plant adjustment: the stem of towel gourd can be up to 7-8 meters long, and it needs to be set up when the vine grows to about 25 centimeters. In order to reduce the space occupied by the frame pole and sunshade, iron wire or nylon rope are generally directly tied to the greenhouse bracket to form a single-row vertical frame, the top is not crossed, and the vine is drawn vertically according to the original planting spacing and density. After the vine is on the shelf, it can be bound every 4-5 leaves, and the "S" shape binding method can be used.

4. Protect flowers and fruits

Daubing with 2mae4Mel D can reduce the number of falling flowers and significantly improve fruit spinning. The concentration is 20 × 10-6 in high temperature and 30 × 10-6 in low temperature. The brush can be applied to the stigma and the base of Corolla of female flowers, or the flowers can be dipped directly in the solution. The smearing time should be around 8: 00 a. M.

5. Disease and pest control

The main diseases of towel gourd are anthracnose, blight and Botrytis cinerea, which can be controlled by carbendazim, chlorothalonil, carbendazim and other pesticides. The main insect pests are melon aphid and whitefly, which can be controlled by fish rattan essence, prochloraz, etc.

The above is the relevant introduction of loofah greenhouse planting technology, I hope it will be helpful to everyone.
