A kind of method for overcoming dragon fruit fruit cracking

Abstract

The invention provides a method for overcoming fruit cracking of dragon fruits. Pollen of the red flesh dragon fruit high-quality variety 'Mihong' is collected and is applied to stigmas of completely opened Xianglong dragon fruit flowers in a hand-pollinate mode, the fruit cracking phenomenon of the Xianglong dragon fruits is overcome, and the fruit quality of the Xianglong dragon fruits is improved.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and in particular relates to a method for overcoming fruit cracking of dragon fruit. Background technique [0002] Pitaya is a perennial climbing succulent plant of the genus Liangtianchi in the cactus family. It belongs to tropical and subtropical fruit trees. It originated in the tropical rainforests and deserts of Central America. It has been artificially cultivated in Central America, Israel, Vietnam, Thailand, the United States, etc.; my country Taiwan has decades of cultivation history, with a development area of ​​about 25,500 mu. The large-scale development of dragon fruit in mainland China started relatively late. In the past ten years, it has flourished in Guangxi, Guangdong, Fujian and other places, with a development area of ​​about 500,000 mu. , Guangxi is about 150,000 mu, Guangdong is about 120,000 mu, Guizhou is about 100,000 mu, Yunnan is about 50,000 mu, Hainan is about 50,00...

[0002] Pitaya is a perennial climbing succulent plant of the genus Liangtianchi in the cactus family. It belongs to tropical and subtropical fruit trees. It originated in the tropical rainforests and deserts of Central America. It has been artificially cultivated in Central America, Israel, Vietnam, Thailand, the United States, etc.; my country Taiwan has decades of cultivation history, with a development area of ​​about 25,500 mu. The large-scale development of dragon fruit in mainland China started relatively late. In the past ten years, it has flourished in Guangxi, Guangdong, Fujian and other places, with a development area of ​​about 500,000 mu. , Guangxi is about 150,000 mu, Guangdong is about 120,000 mu, Guizhou is about 100,000 mu, Yunnan is about 50,000 mu, Hainan is about 50,000 mu, Fujian is about 35,000 mu, and it is developing rapidly. About 80% of the red-fleshed dragon fruit varieties planted in the fruit-producing areas are old varieties, which require manual pollination, high manual production costs, small fruit weight, poor quality, and low production efficiency

[0003] "Xianglong" dragon fruit is a red-fleshed dragon fruit variety that was vigorously developed in Fujian pitaya production areas in the past. It has a relatively large development area, accounting for more than 50% of the area of ​​Fujian pitaya. Compatible type, the fruit setting rate of self-pollination is only about 15%, but the fruit setting rate of cross-pollination is relatively high, which can reach more than 96%. Thin, red flesh, crisp, soft and juicy, 13.8%-16.5% soluble solids, aromatic, good taste, densely grown black sesame seeds between the flesh, edible, slightly fragrant, edible rate 65% % to 76%, the quality is excellent, but the fruit cracking is serious in production, which reduces the commodity rate of "Xianglong" pitaya and affects the economic benefits of pitaya production
