摘　　要：通过黔糖 4号秋季繁殖原种试验研究结果表明 ,采用优选原种、晒种、秋季种植、地膜覆盖、及时追肥、适时采收、加强宿根管理等技术措施 ,从而实现一次秋繁 ,四年六采及即采即繁的加速原种繁殖目的 ,可较常规繁殖增加种芽数38.6 % ,繁殖量提高 2 9.4 %。The results from the experiment of autumn-propagation of Qiantang 4 showed that the speedup original seed propagation with 'six harvest in four years by one autumn-propagation' can be obtained by the technique including selecting good original seed-stock, exposing-seed to the sun, autumn-sowing, plastic mulching, dressing fertilizer in time, harvesting at the (optimum) period and enhancing the management of biennial root, and so its bud number and (reproductive) quantity increased by 38.6% and 29.4% compared with those of the conventional reproduction separately.
