What are the seed retention techniques of towel gourd in greenhouse? How to operate it exactly?

Nowadays, many growers choose to grow towel gourd in greenhouse, and when planting towel gourd in greenhouse, keeping seeds is an important foundation to grow towel gourd well. So what are the seed retention techniques of towel gourd in the greenhouse? How to operate it exactly?

1. Strictly select the remaining plants.

The plants with remaining seeds should be strictly selected. the specific requirements are uniform leaf size, short petiole, short internodes, uniform position of melon nodes, early melon sitting and no disease.

Pre-management:

Towel gourd before sitting to cultivate strong trees, in the plant has 5-6 leaves, about 50 cm high hanging vine, the first fertilizer to promote the early growth of the plant. Over-summer loofah should pay attention to the time of hanging vines should be delayed as far as possible, it is best to hang vines when the female flowers open, first let towel gourd crawl on the ground to prevent the plant from growing. After hanging the vine, it is necessary to remove the germinated lateral branches and flowers on the main vine in time to reduce nutrient consumption and promote the robust growth of the main vine.

2. Pay attention to the time of keeping seeds.

In addition to choosing plants to retain seeds, we should also pay attention to the time of keeping seeds, because it takes about 3 months from seed retention to harvest, during this period, there is basically no yield of towel gourd, so it is best to choose the time when the price of towel gourd is low in May.

Many vegetable farmers usually start to keep melons when the main vine has 15 leaves. The retention of melons sooner or later should be determined according to the season. Spring and autumn towel gourd will leave melons a little early when there are 15 leaves in the main vine, because at that time the external temperature is too low, it is easy to cause an imbalance in nutrition distribution, and the stem vine will grow slowly because it does not get adequate nutrition. When the temperature is low, the first loofah can be delayed to 22-24 leaves. The summer temperature is higher, so the over-summer towel gourd should leave the first stubble melon before 20 leaves as far as possible.

3. Detoxify the virus before leaving the seed

Towel gourd has always been dipped in flowers in the process of planting, because these hormones dipped in flowers will be transmitted up and down with the transport of nutrients, which has a negative impact on the development of seeds, so it is necessary to detoxify towel gourd first. The specific measure is to let the plant grow freely for a period of time before retaining melons. During this period, the young melons and tendrils at all nodes can be pinched off, and after they grow 10-12 leaves again, they will begin to top, fall vines, and leave melons.

4. Post-seed management

There is no need to apply fertilizer to towel gourd when keeping seeds, because the nutrients in the soil are enough for the growth of towel gourd, and attention should be paid to water management in terms of water management. It is best to wait until the plant has withered and died before collecting seeds. In the process of seed retention, we should also pay attention to the prevention and control of root-knot nematode disease, which can be prevented by 1-2 times of avermectin solution.
