Key points of loofah planting and management technology

When we cultivate loofah in the greenhouse, what aspects should we pay attention to in terms of management? Here are the key points of loofah management technology:

1. Adjust the temperature and light.

The optimum temperature for the growth of loofah is 24℃-28℃. The temperature in the greenhouse should be kept at 25℃-30℃ during the day and around 18℃ at night. Before the loofah starts to grow, the sunshine time can be properly controlled by using straw thatch to promote the growth of stems and leaves and the differentiation of female flowers. During the flowering and fruiting period, the straw thatch should be opened in time to make full use of the sunlight to increase the temperature.

2. Water and apply fertilizer in time.

When the vine grows to about 5 cm, combine it with soil cultivation again, apply 30 kg of potassium dihydrogen phosphate per mu, and water it once. After flowering and fruiting, water it once every 7-8 days, and apply 5 kg of urea per mu.

3. Set up frames, tie up vines, and adjust plants.

The stems and vines of loofah can be up to 7-8 meters long. When the vines grow to about 25 centimeters, they need to be put on a frame. Generally, iron wire or nylon rope is directly tied to the greenhouse frame to form a single-row vertical frame, without crossing the top, and the vines are led vertically upward according to the original planting row spacing and density. After the vines are on the frame, they are tied once every 4-5 leaves, and the "S" shape can be used.

4. Protect flowers and fruits.

Applying 2.4-4D to flowers can reduce flower drop and significantly increase fruit setting rate. The concentration is 20×10-6 when the temperature is high and 30×10-6 when the temperature is low. You can apply the liquid to the stigma and corolla base of the female flower with a brush, or you can directly dip the flower in the liquid. The application time should be around 8 am.

The above are the detailed management points of loofah greenhouse technology. You can take a good look at it.
