Description
Technical field
The invention belongs to technical field of agricultural cultivation, and in particular to a method of accelerate dragon fruit cuttage and seedling culture process.
Background technique
Dragon fruit [Hylocereus undatus spp.] also known as Hylocereus undatus, pitaya fruit, Qing Renguo, sesame fruit etc. are
The succulent plant of perennial the climbing up by holding on to property of Cactaceae (Cactaceae) hylocereus category (Hylocereus undatus) belongs to heat
Band, subtropical fruit tree, tropical rain forest and desert region originating from Central America, artificial cultivation spread Central America, Israel, get over
The tropical area of the country such as south, Thailand, U.S., China's Mainland over the past decade Guangxi, Guangdong, Hainan, Guizhou, Yunnan,
The ground such as Fujian rise cultivation, develop about 750,000 mu of area, growth momentum is powerful, has a extensive future.
Since dragon fruit is the whiplike class plant of fleshy stem, originating from tropical desert area, vigorous, rudiment power and hair branch are grown
Power is strong；In temperature area higher, can grow throughout the year, no dormant period, and shoot growth is fast.Its blade has been degenerated to pierce,
Respectively with short 1-6 pieces of thorn, photosynthesis function is undertaken every section of branch recess by stem, and branch is dark green, meat, sturdy, more
In triangle column or quadrangular shape, into the best fruiting period after branch width up to l0~18cm.The inside of stem be largely be full of it is viscous
The parenchyma cell of thick liquid is conducive to absorb moisture as much as possible in rainy season, and the center of stem is a lignifying, columned
The main vascular tissue in center, toughness is strong, plays a part of conveying nutrition and supports fixed plant.Dragon fruit bough surface has one layer
Thickness is hard and hydrophobicity wax coat, water retention property are strong, and this physilogical characteristics make dragon fruit have stronger drought-resistant ability；Branch simultaneously
On surface have a large amount of brown aerial roots, it plays the role of the growth of dragon fruit plant critically important, it is in addition to that can climb
It helps outside fixed dragon fruit plant, moreover it is possible to play the role of absorbing the moisture and nutrient in air.
The method of dragon fruit breeding mainly has Seedling propagation, cutting propagation and three kinds of propagation by grafiting.Seedling propagation need compared with
The long time and seedling cannot keep the inhereditary feature of kind well, can morph and seldom be used；Propagation by grafiting exists
The coastal dragon fruit producing region for thering is typhoon frequently to occur can the phenomenon that graft union position fractures frequent occurrence, dragon fruit currently on the market
The more general cuttage seeding of grafting price is higher by one times, and since grafting operation is cumbersome, it is more demanding to manage and protect condition, breed it is slower,
It is not able to satisfy the needs of current dragon fruit seedling wilderness demand, therefore propagation by grafiting yet less use in dragon fruit production.
Dragon fruit seedling breeding is mainly realized by cuttage approach at present, and cuttage seeding breeding is easy, can be hereditary well
The good characteristic of maternal plant, and propagation material source is wide, after the fruit harvesting of annual dragon fruit end batch, as a result 3 years or so old
Branch needs renewal pruning, provides a large amount of branch for the cuttage seeding breeding in production, and when breeding, selection is healthy and strong, plump, growth
Gesture is strong, no disease and pests harm, the aging branch for still having several effective sprouts, unified to be sheared according to the length of every section of 30cm, is placed on
Shady place 7 days, planting depth 3-5cm, pay attention to that soil is kept to have suitable water content.By taking pains to foster, after 1.5 months
The root system that 3-5 item is about 5-8cm is grown, for planting in production.But this traditional cuttage and seedling culture is by single branch with one
Fixed spacing is inserted directly into soil, needs bigger nursery soil, and when emergence, it is still necessary to excavated by manual work to rise, and take a lot of work, and be easy to cause perhaps
More root systems are dug disconnected, are not able to maintain the integrality of root system, and this cutting propagation efficiency is lower, breed it is costly, take it is longer,
The reproduction speed of dragon fruit cuttage seeding is affected to a certain extent.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for accelerating dragon fruit cuttage and seedling culture process.The technology of the present invention is simple,
Using the method for the cuttage and seedling culture that do not bury, production efficiency is greatly improved, there is good application and popularization value.
To achieve the above object, the present invention adopts the following technical scheme:
A method of accelerating dragon fruit cuttage and seedling culture process, specific steps include:
(1) cut with secateurs and be about the aging dragon fruit bough of 30cm, under aging branch at clip 5cm with sharp small
The trigone of branch or tetragonous stem meat are chamfer wedgewise by knife, expose intermediate vascular bundle about 1cm, and in 600 times of thiophanate methyls
It is impregnated 1 minute in liquid, eliminates germ, placed in the cool after taking-up 7 days, allow wound is dry to heal.
(2) dragon fruit bough is bundled into 1 bundle (separately putting well end to end) with cloth or kernmantle by every 10, wedge shape will be whittled into
