Why does the red dragon fruit rare crack the fruit?

Why does the red dragon fruit rare crack the fruit? Please introduce the reasons and control methods of dragon fruit plants are entering the period of concentrated flowering. Its flowering usually begins from 1 to 1.5 hours before sunset, the Corolla gradually closes after dawn, and withered after sunrise. During the above-mentioned period, the flower completes the process of self-fertilization. However, at present, heavy rain, torrential rain and less sunshine are extremely disadvantageous to the pollination and fertilization of dragon fruit, such as the heavy rain dilutes the mucus of the female stigma, the male anther fluid is washed and lost, and the flowers are bound to wither and fall off without the completion of fertilization. In addition, because there are more Rain Water at present, and the plant absorbs relatively more water, the speed of pulp development and expansion is not synchronized with the growth rate of pericarp, so fruit cracking is also increased. In order to overcome the above unfavorable factors, it is necessary to adopt protected cultivation, such as greenhouse cultivation in transparent light. If planted in the open field, when it is not conducive to plant flowering, pollination and fertilization, is not conducive to water, light and other factors, it is difficult to ensure stable yield, high yield and high quality. It is recommended that you cover the soil with thin film as far as possible, reduce the soil water content and keep the soil water content as uniform as possible; spray 0.04PPM brassinolide on the plant when the weather clears up to improve the stress resistance of the plant; using artificial pollination, you can use a brush to collect pollen and caress the female stigma before thanking flowers in the early morning. As the concentrated flowering period of dragon fruit is generally from late June to early July, from late August to early September, and from mid-late September to early October, it is suggested that pollination and fruit setting management should be strengthened in the later period to make up for the temporary loss.
