茶树良种繁育体系茶树良种繁育体系prapagating system of improved tea varieties茶树良种繁育体系(propagating systemof imProved tea varieties)把育成并经审定的茶树优良品种，投入生产的一系列组织和制度。它的任务是保持良种原有的优良种性和纯度，迅速扩大繁育良种种苗，有计划地进行品种更换和复壮，以满足生产上对茶树良种种苗的需要。茶树良种萦育体系的建立.应由国家根据茶叶自然区划，以及茶类和良种布局建立良种繁育组织和基地，各主产茶省区、地、县在统一布局下，相应地都应建立为本地区推广良种的繁育组织和基地.逐步实现以县为单位统一供种。茶树良种繁育体系应由三级单位组成，即原种场.良种繁殖场和生产单位.它们的关系如图所示:┌───┐┌────┐│原种场││生产单位│└───┘└────┘ ┌──────┐ │直接供应种苗│ └──────┘在健全茶树良种繁育体系的同时，要建立各项规章制度.在进行采种(采稼)、育苗(扦插)、出圃、包装、运输、种植等作业时，都要严格遵守繁育技术规程.以保证在良种繁育过程中，防止人为地机械混杂:采用有性繁殖时，对不同品种间要进行适当隔离，避免发生天然杂交.造成生物学混杂。为满足生产单位对良种的需要，根据茶树的特点.在繁育途径上可采用无性繁殖与有性繁殖相结合，以提高繁殖系数。(王融初)
