以黔糖4号作供试材料,通过四步法选种、种苗处理、深沟种植、一次性施肥、全程盖膜免耕、适时采种扩繁(即采即繁)与强化宿根繁殖并重等一系列组装技术配合实施,经2年为一个繁殖周期的试验研究,摸索了一套加速黔糖4号原种繁殖的新技术即两年三采加速原种繁殖法,一个繁殖周期的原种繁殖量可增加419倍,较对照(CK)的51. 1t,净增加367. 41t,增幅达719%,繁殖系数达419,繁殖速度较对照(CK)增加8倍以上,是一项良种加速繁殖、投资少、见效快、操作简便、实施容易的新技术,是甘蔗蔗茎大田繁殖种苗速度较快的新方法,比较适合贵州蔗区应用推广。
Using Qiantang 4 as test material, four-step seed selection, seedling treatment, deep grooving, one-time fertilization and full-time film-free tillage were adopted. And a series of assembly technology with the implementation of the two years as a breeding cycle of experimental research to explore a set of new technologies to speed up the proliferation of Guizhou Sugar 4 Protozoa that three years to accelerate the original seed breeding method, a breeding cycle of the original Seed breeding can increase 419 times, compared with the CK (CK) of 51. 1t, a net increase of 367. 41t, an increase of 719%, the breeding coefficient of 419, propagation rate increased more than 8 times CK (CK) Accelerated breeding, less investment, quick, easy to operate, easy to implement new technology is the sugarcane cane field breeding seedlings faster new method, more suitable for the promotion of sugarcane planting in Guizhou Province.
