Embodiment 1

[0033] Research on pitaya tree management methods was carried out at the test base of Yunnan Institute of Tropical Crops Science (Jinghong City).

[0034] A kind of tree body management method that improves red-fleshed pitaya output, comprises the steps:

[0035] Step (1), pruning old branches: the last batch of dragon fruit in 2014 was harvested on November 16, and the test tree was pruned on November 18. Cut off the dense inner branches, the branches that cannot be exposed to the sun, the old side branches with a length of less than 20 cm, and the branches with poor growth and severe disease spots and insects, and keep them strong, strong in growth, extending around, and good in direction for one year. And / or 50 biennial shoots in total, as fruiting shoots for the next year;

[0036] Step (2), removing new shoots: when there are 34 days before the flower buds germinate, remove the over-dense, weak and upright new shoots above the top support of the cement pile, and keep 20 ...

Embodiment 2

[0053] In the pitaya base of Fengnian Company in Yuanjiang County, Yunnan Province, research on pitaya tree management methods was carried out.

[0054] A kind of tree body management method that improves red-fleshed pitaya output, comprises the steps:

[0055] Step (1), pruning old branches: the last batch of dragon fruit in 2014 was harvested on November 5th, and the test tree was pruned on November 6th. Cut off the dense inner branches, the branches that cannot be exposed to the sun, the old side branches with a length of less than 20 cm, and the branches with poor growth and severe disease spots and insects, and keep them strong, strong in growth, extending around, and good in direction for one year. And / or 60 biennial shoots in total, as fruiting shoots for the next year;

[0056] Step (2), removing new shoots: When there are 38 days before the flower buds germinate, remove the over-dense, weak and upright new shoots above the top support of the cement pile, and keep 19 ...

Embodiment 3

[0073] In the pitaya base of Fengnian Company in Yuanjiang County, Yunnan Province, research on pitaya tree management methods was carried out.

[0074] A kind of tree body management method that improves red-fleshed pitaya output, comprises the steps:

[0075] Step (1), pruning old branches: the last batch of dragon fruit in 2014 was harvested on November 5th, and the test tree was pruned on November 6th. Cut off the dense inner branches, the branches that cannot be exposed to the sun, the old side branches with a length of less than 20 cm, and the branches with poor growth and severe disease spots and insects, and keep them strong, strong in growth, extending around, and good in direction for one year. And / or 40 biennial shoots in total, as fruiting shoots for the next year;

[0076] Step (2), removing new shoots: When there are 30 days before the flower buds germinate, remove the over-dense, weak and upright new shoots above the top support of the cement pile, and keep 21 ...

Abstract

The invention relates to a tree body management method for increasing the yield of red pulp type pitaya, and belongs to the technical field of fruit tree management. The method comprises the seven steps of old branch trimming, new shoot removing, topping, flower thinning, pollen collecting, pollinating and fruit thinning. According to the tree body management method for increasing the yield of the red pulp type pitaya, a traditional cultivation technology of the red pulp type pitaya is broken through, it is proposed that artificial pollination needs to be conducted under any climate condition, flower thinning is conducted by combining pollen collection, and the best time period of artificial pollination is within four hours after the flowers bloom; topping on too long branches is put forward firstly, and the number of trimmed sprouts is quantized. According to the tree body management method for increasing the yield of the red pulp type pitaya, the method is specific, the standard is quantized, maneuverability is very high, fruit setting of the red pulp type pitaya and fruit development are greatly facilitated, and therefore the yield is obviously increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree management, and in particular relates to a tree body management method for increasing the output of red-fleshed dragon fruit. Background technique [0002] Pitaya is a fruit cultivar of the genus Seleniereus Meja-lantous of the cactus family (Cactaceae), which originates in Central America and is a new tropical fruit. Dragon fruit has high nutritional value and good taste. It belongs to the health food of "one high and two low" with high vitamin, low sugar and low fat. Coupled with the narrow area suitable for its development, the current domestic market is in short supply, and the planting income is quite considerable. After 3 years of planting, the output value per mu can reach more than 15,000 yuan. According to the color of its skin and flesh, dragon fruit can be divided into three types: red skin with white flesh, red skin with red flesh, and yellow skin with white flesh. Red skin with re...
