Management of flowering stage of towel gourd

The field management of towel gourd after planting is very important and is the best way to maintain growth, but the focus of field management is the management of the flowering period of towel gourd. General flowering means that towel gourd from vegetative growth to reproductive growth, it is necessary to start fertilization and water supply, promote a large number of flowering, high-quality flowering, but also avoid physiological falling flowers, and sparse flowers to retain good flowers to bear fruit. Let's take a look at how to manage these aspects.

I. sowing at the right time

Towel gourd can generally blossom and bear fruit well under short-day conditions, so it is best to sow in winter and plant in early spring, when towel gourd blossoms can accept short-day sunshine. If planted in summer, flowering will be delayed or difficult to bloom. Therefore, it can be appropriately delayed or planted in advance according to the sunshine in different areas.

Second, fertilizer and water

About half a month before flowering, it is necessary to increase the application of quick-acting compound fertilizer, reduce the amount of nitrogen fertilizer or apply about 200 jin of farm manure per mu to ensure a sustained supply of nutrients throughout the flowering period. In addition, boron fertilizer and phosphate fertilizer were sprayed on the leaves to provide nutrition for flowering. Towel gourd root system is not strong, poor water absorption, can be concentrated irrigation in irrigation, lack of water will cause rotten flowers, flower edge scorched, dry rot and fall. However, if there is too much water, it may be infected with flower rot to drip, stink, grow mold, and finally rot and fall flowers. In addition, towel gourd lacks boron. Calcium can easily cause the disease of style decay.

Third, protect flowers and promote fruit

Towel gourd may have physiological flower drop when it blossoms, that is, a large number of flowers suddenly fall, which is disadvantageous to the fruit, so it is necessary to spray naphthalene acetic acid or 2mem4Mel D during flowering to keep the flower from falling. But the nutrition of the tree is limited, in order to sit fruit as much as possible, it is necessary to sparse flowers when blooming too much, and you can keep 5 to 8 flowers on each vine. In addition, each batch of flowers should be thinned. The purpose of flower thinning is to concentrate nutrition, retain high-quality flowers, concentrate on plant nutrition to increase fruit setting rate and increase yield.

IV. Plant pruning

After flowering, some extra branches and vines can be pruned to save nutrition and ensure flowering nutrition, but do not remove two leaves on the top of the flower, otherwise it is easy to fall flowers, it is best to remove the lower old leaves and redundant tendrils, dense branches and vines. It can improve the internal space, increase light and function, and reduce humidity to reduce the occurrence of diseases and avoid the phenomenon of rotten flowers. During flowering, insects should be prevented from harming flowers and falling flowers.

Towel gourd flowering needs to pay attention to some problems, but also need to pay attention to all aspects of management, mainly through management to protect flowers, select high-quality flowers to promote fruit setting and improve fruit quality. Therefore, the flowering stage is the key management period of towel gourd planting management.
