Key technical points of towel gourd thinning and beard removal

The reasonable male thinning and whisker removal of towel gourd can reduce the unnecessary consumption of nutrients in soil and plant, make it concentrate on fruit growth and development, and thus increase the yield per unit area. The experiment showed that under the condition of the same cultivation and management, compared with the non-thinning towel gourd, the setting rate per plant, weight and yield per plant increased by 17.9%, 15.9% and 36.8%, respectively. Now the practice of thinning male and removing beard is introduced as follows: first, sparse male towel gourd is a cross-pollinated crop. The female flower has one flower and one fruit, about 15 days from budding to fruit harvest. Male flowers are infinitely growing racemes, each inflorescence can open 20-35 flowers, the total number of male inflorescences per plant is more than the number of female inflorescences, and the pollination ability greatly exceeds the requirement of female flowers. Because the florescence of male inflorescence is longer, about 30-40 days, which is 3-4 times longer than that of female flower, a lot of nutrients are consumed during this period. Therefore, removing the excess male inflorescence as soon as possible can save nutrients and supply the need for female flowers to bear fruit. The method of male thinning: starting from the budding of female flowers, 80% of the male inflorescences on each litter of towel gourd plants are removed and 20% pollinated. Second, remove the beard. Tendrils play a role in climbing and encircling branches in trailing crops. Towel gourd tendrils take a long time from occurrence to death and consume more nutrients, which is not conducive to more melons and good melons. Removing tendrils and using artificial binding instead of climbing function are beneficial to the progress of plant photosynthesis, the manufacture and accumulation of nutrients, the control of diseases and insect pests, and make towel gourd good pollination and high yield. The method of removing beard: in the early stage of towel gourd plant growth, the method of removing beard and binding is adopted to draw the vine to the scaffolding; after the branches are evenly distributed and fixed on the scaffold, the tendrils can be removed at any time with the whole vine.
