The Research On Resource Survey And Fine Species Selection Of Rubus In Henan Province

In this paper，wild rubus plants in henan province mountain area was researched as theresearch object. By the way of data collection, field investigation and specimens study, developresource survey of wild rubus in henan province,mastering the resources distribution and growthcondition. On this basis,compare the fruit nutrient content of seven superior rubus, screeningfour good quality rubus according to its fruit condition,and research the breed way and efficientcultivation technology, to provide theory support for developmental research of wild superiorrubus in henan province.The results of this study are as follows:1.After investigation, there are30species and5varieties rubus in henan province, whichinclude9single-leaf and21multi-leaves. R.t aangii Merr. is the new distribution of plants inhenan rubus（affirm tentatively）.Rubus, mostly deciduous shrubs,mainly distributed in the mountain area of above500maltitude, hillside brush, valley and besides streams, by the side of the road,sparse woods,rarelyseen below dense woods.In addition to R.mesogaeus Focke, others are fond of sunlight.Wild rubushave developed roots and exuberant vitality, can be able to bear drought and poor soil, still cansurvive in the chelt and less soil by the roadside. Thirty kinds of rubus in Henan province mostlybloom in spring from May to June, and result in July to August. R.corchorifolius L.f. blooms inearly spring and results in late spring, the time of blooming and resulting is first; R.lambertianusSer.,the latest bloom and result time, have flower at the end of summer and fruit in early autumn.2. According to the distribution number、fruit diameter、fruit amount and fruit taste etc,wefilter out R.lambertianus Ser.、R.corchorifolius L.f.、R.ceoreanus Miq.、R.flosculosus Focke、R.phoenicolasius Maxim、R.taangii Merr.、R.parvifolius L.7kind of primarily fine rubus.Then combined with nutrient content and other indexes,we choose R.corchorifoliosL.f.,R.ceoreanus Miq.,R.taangii Merr.,R.parvifolius L.as the fine cultivated species.R.corchorifolios L.f. is upright shrubs, can be breed by ramets propagation and rootpropagation. R.ceoreanus Miq. growing power is exuberant and live easily, can be breed byramets propagation,root propagation, layering propagation and burying propagation. R.taangiiMerr. main be breed by means of root propagation and ramets propagation. R.parvifolius L. can be breed by layering propagation and root propagation.
