Abstract

The invention discloses a cuttage propagation method of melastoma dode candrum lour, comprising the following steps of: selecting the vegetative growth leaf-developing stage of wild seedlings of the melastoma dode candrum lour to acquire seedlings for cuttage; planting under an open-air environment by using the natural surface soil of the growing environment of the melastoma dode candrum lour as cuttage matrix soil; and selecting and providing conditions which correspondingly accord with a natural living environment for plants of the melastoma dode candrum lour. The invention greatly enhances the survival rate, only needs to manage soil water for cuttage stem seedlings without special treatment by adopting a rooting agent and the like and has the advantages of simple process, extensive management, lower cost and easy popularization.

Description

The cuttage breeding method harvested
Technical field
The present invention relates to the vegetative propagation technique of a kind of wild plant, be specifically related to a kind of method of utilizing cottage propagation wildly to harvest.
Background technology
Along with the demand to plant variety such as city trees and shrubs and slope protection greening, wild indigenous plant more and more receives publicity, much grow extensive, pattern is bright-colored, the florescence is long, the kind that has ornamental value is all being attempted development and use.But to the development and use of wild indigenous plant, rest on the spontaneous situation of excavating, transplanting and supplying with at a low price for a long time, particularly to the development and use of wild ground cover plant of one's native land.If things go on like this, both be unfavorable for protecting wild plant germ plasm resource, also be unfavorable for the wild indigenous plant of Application and Development better.
The artificial propagation means are the important means that solve seedling supply, the wild indigenous plant of rational exploitation and utilization at present.
Harvest, formal name used at school Ma! Astoma dodecandrum lour., belong to Melastomataceae tomonea platymiscium, claim open country fall eggplant, Fructus Fici tikouae, PUDIJIN again, be the undershrub of high 5~15cm, the tool stem is crawled or is hung down loosely, and takes root by joint in the bottom, the stem multi-branched, acid ground is born in happiness, spreads all over characteristics such as southern massif, is that the flower ground cover plant is seen in a kind of good wild native soil that is worthy of popularization.
The propagation method of harvesting comprise seminal propagation and plant division, cottage propagation.Have a resting stage of growing because seed is harvested on ground, the seed sprouting survival rate is low, and, from the seed germination to the plant blossom, often needing the time in 2~4 years, the breeding cycle is very long, the development and use of harvesting with being unfavorable for; Adopt plant division, cottage propagation, can shorten the time of plant blossom greatly, shorten the breeding cycle.But division propagation needs destructiveness to excavate seedling, causes the destruction to wild plant resource easily.
To harvest the cottage propagation technology still at the experimental stage existingly, and the stem seedling is adopted root-growing agent processing and cool canopy management down, and rootage duration was about for 2 weeks, and survival rate is about 60%~70%; The sandy soil cuttage survival rate is 39.50%, through dropping to 17.5% behind the winter low temperature; The laterite cuttage survival rate of shading is 44.0%, and not shading cuttage survival rate is 38.7%.The modes of reproduction that adopts tissue culture is also arranged, but technology is complicated, is difficult for promoting.
Summary of the invention
The present invention is directed to the deficiency of harvesting propagation technique existingly, the cuttage breeding method of harvesting is provided a kind ofly, need not use root-growing agent to handle and the cool canopy management, effectively improve survival rate.
The cuttage breeding method of harvesting may further comprise the steps describedly:
(1) the plants stems seedling is wildly harvested in collection, keeps the root on the hypomere plant joint;
Be preferable over to gather in the open air for 3~September and harvest plant well-grownly, gather the ground of the leaf stretching period of nourishing and growing and harvest plant, get stem section, and note keeping the root on the hypomere plant joint near root.
(2) remove harvest the plant head portion with gathering, the stem section of getting near root is harvested wild cuttage seeding as ground; The preferred stem section 10~15cm that keeps;
(3) get with ground harvest growing environment close show naturally native as the cuttage soil matrix;
The above-mentioned cuttage soil matrix nutritious bag of can packing into, cuttage is carried out in nutritious bag.
The preferred scheme of the present invention is to add water-loss reducer in above-mentioned soil matrix, according to 1.0~1.5g water-loss reducer: the ratio of 1000g cuttage soil matrix adds the cuttage soil matrix with water-loss reducer, described water-loss reducer is a hydroscopic high-molecular resin, specifically can select polyvinyl lactam class, polyacrylamide or polyacrylic water-loss reducer for use, optimization polypropylene acids water-loss reducer.
(4) step (2) is harvested wild cuttage seeding readyly be planted in cuttage, water immediately after planting with in the soil, water the water yield with soil drench till;
If adopt the mode cuttage of nutritious bag, each bag 1 seedling of planting, the about 5~8cm of buried depth, the joint that stem seedling hypomere is taken root is imbedded in the soil as far as possible.
After arrive the time of planting in preferred annual rainy season in March, finish to rainy season in September.
(5) grow seedlings under the open area condition, keep ground moistening;
Added water-loss reducer in the soil, watered 1 time every 4~5 days, water at every turn the water yield with soil drench till; But meeting the proper extension that rains waters the cycle.Planting early stage as if meeting heavy rain, then need to adopt suitable covering measure according to routine, prevent that heavy rain from washing away.
Do not add water-loss reducer in the soil, continuing not under the situation of raining, at planting time preceding 10 days, water every day 1 time; Meeting rains can not water.In the later stage, watered 1 time every 3~4 days.
The wild[l of gathering must in time be planted, and the inventive method was collected seedling the preferred same day, and planted the same day.
Compare with present propagation technique, the technology of the present invention has following beneficial effect:
(1) survival rate is higher: the present invention selectively harvests the wild[l leaf stretching period of nourishing and growing and gathers the cuttage seedling, plant strain growth is vigorous, the soil of table naturally of harvesting growing environment as cutting medium soil with adopting, plant under the environment in the open, harvest plant for ground relative consistent condition with natural habitat is provided, survival rate improves greatly.
(2) technology is simple: cuttage stem seedling need not specially treated, need not breeding and seedling under cool canopy, and technology is simple, and this point is particularly suitable for to slope protection greening engineering in the highway construction provides the bank protection plant seedling, can gather materials on the spot, the scene breeds seedling.If in soil matrix, add a small amount of water-loss reducer, more can reduce the amount of labour of watering.
(3) extensive management: in the breeding and seedling process, only need carry out soil moisture management, note watering in good time, keep ground moistening to get final product.Because adopt the open area cuttage, do not need chemicals treatment such as root-growing agent, cost of the present invention is lower, is easy to promote.
