A kind of efficient high yield cultivating method of red heart dragon fruit
Technical field
The invention belongs to the cultivation field of fruit tree, is specifically related to a kind of efficient high yield cultivating method of red heart dragon fruit.
Background technology
Dragon fruit is that Cactaceae triangular prism belongs to perennial trailing plant, is divided into red, white, yellow dragon fruit three according to pulp colour
Individual subspecies, it is a kind of emerging fruit for having good health-care efficacy.Originate in the Western Hemisphere equator, Central America tropical rain forest land
Area.Thus its biological nature is determined:1. it is heat-resisting, it is not low temperature resistant.40-50 DEG C is resistant to, and is then had below 8 DEG C in various degree
Cold damage, can be freezed to death less than 0 DEG C.2. it does not come from dry-heat desert and comes from tropical rain forest, therefore " nature " non-happiness is arid and hygrophilous
Profit.Its root is not afraid of water intolerant to water logging, but not resist oxygen lack.Thus its cultivation feature is determined, does not ask and plants and Ying Qianzhi deeply,
Draining facilitates, and earth's surface preferably keeps the weeds in the covering of one layer of loose ventilative moistening, such as dry branches and fallen leaves or growth, imitates
According to the growth conditions of its ancestors, aerial root is wriggled in near-earth superficial and stretch water suction suction fertilizer.
Existing red heart dragon fruit cultural method, technology is extensive, causes dragon fruit slow-growing, fruiting rate is low.
The content of the invention
Present invention aims at:In order to solve the problems, such as that the prior art in above-mentioned background technology is present, there is provided Yi Zhongsheng
Long speed is fast, the high efficient high yield cultivating method of red heart dragon fruit of fruiting rate.

(2), site preparation and fertilization:In spring, sand is chosen, builds planting greenhouse, it is deep after mixing organic fertilizer in soil
Ridge is dug, fixed column is buried on ridge, spacing is 1.5~2m between adjacent fixed column, and spacing is 1.9~2m between adjacent ridge;
(3) seedling, is transplanted:4 planting pits are uniformly dug around each fixed column, one is planted in each planting pit
The red heart dragon fruit seedling that step (1) is cultivated, after soil backfill around seedling root mulching straw/wheat straw, in field planting 5 days
Afterwards, watered daily toward dragon fruit seedling root, irrigate the soil of root every time, continuously watered 15~20 days;
(4), bud thinning sparse branching:After dragon fruit major branch length to 1.2~1.4m height, by apart from 60~below 70cm's of ground
Bud is all erased, and cuts off the part of 10~15cm at the top of major branch, and the annual first half of the year, every major branch stays 1~3 root growth stalwartness
Branch, the annual second half year, the branch newly sprouted all remove;
(5), pollination fruit thinning:Artificial pollination is carried out during the florescence, uses ring lithography to remove faded flower after first, works as young fruit
When transverse diameter reaches 2~2.5cm, one well-developed young fruit of every reservation, its co-meager is gone, and pericarp annesl is front and rear to fruit set
Bag, remove during harvesting.
Preferably:In step (1), 3~4 branches are retained on dragon fruit branch.
Preferably:In step (1), greenhouse temperature is maintained at 22~27 DEG C.
Preferably:In step (2), organic fertilizer includes matrix, organic liquid manure and trace element;
