Greenhouse loofah planting, greenhouse loofah management technology

I think some farmers are familiar with the management techniques of greenhouse loofah. Let’s learn about it below.

Loofah

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 grows, 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 fertilize 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 to 8 days, and apply 5 kg of urea per mu.

3. Build a frame and tie up the vines, and adjust the plants. The stems and vines of loofah can be up to 7 to 8 meters long. When the vines grow to about 25 centimeters, a frame needs to be built. Generally, iron wire or nylon rope is directly tied to the greenhouse support 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 to 5 leaves, and the "S" shape can be used.

4. Preserve 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.

5. Management in the shed

Adjust the temperature and light. Luffa requires a higher temperature throughout the growth period. The optimum temperature for growth is 20℃～24℃, and the optimum temperature for fruit development is 24℃～28℃; growth is slow at around 15℃, and growth is inhibited below 10℃. During management, the temperature in the greenhouse is kept at 25℃～30℃ during the day and around 18℃ at night. Before the luffa vines grow, the sunshine time can be properly controlled by using straw thatch to promote stem and leaf growth and female flower differentiation. During the flowering and fruiting period, the straw thatch should be opened in time to make full use of the sun to increase the temperature.

Water and fertilize at the right time. The loofah seedlings do not require much water in the early stage. Depending on the soil moisture, you can water them 1 to 2 times. When the vines grow to about 5 cm, combine it with soil cultivation again, apply 30 kg of potassium dihydrogen phosphate per mu, and water them once. After flowering and fruiting, water them generally once every 7 to 8 days, and apply 5 kg of urea per mu at the same time.

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 framed. In order to reduce the space occupied by the frame and provide shade, iron wire or nylon rope is usually used to tie it directly to the greenhouse support to form a single-row vertical frame without crossing the top. 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. The "S" shaped tying method can be used.
