浙江省水稻品种发展现状与对策
|
摘要
对2007—2018年期间浙江省的水稻品种结构进行统计分析,发现浙江省水稻品种结构存在以下特点:品种类型丰富,主导品种面积集中,通过审定的优质稻品种数逐年上升,但优质性状不够稳定、真正食味佳品质优的水稻品种占比不高。当前制约优质稻发展的因素主要有:优质稻产业发展思路有待理清,优质稻品种评价标准有待完善,优质稻品种选育攻关进展不快,优质稻品种推广与产业化发展有待深化。为进一步深化浙江省优质稻品种推广与产业化发展,下一步浙江省需从以下4个方面着手:注重优质稻产业发展的顶层设计,继续完善品种审定和评价标准,加快优质稻品种选育攻关和深化优质稻品种的示范推广。
Based on the statistical analysis of the approval rice varieties from 2007 to 2018 in Zhejiang province, it was found that the rice variety structure in Zhejiang province had the following characteristics: the rice variety types were very rich; the dominant vari-eties had a large planting area; the number of approval rice varieties with high quality was increased gradually; the quality characters were not stable and the proportion of rice varieties with good taste and high quality was still small. There are four main factors to re-strict the development of high quality rice varieties: the development ideas of high quality rice need to be cleared up; the evaluation standards of high quality rice varieties need to be perfected; the progress of the rice breeding with high quality was not fast; the promotion and industrialization of high quality rice need to be deepened. In order to further deepen the promotion and industrialization of high quality rice in Zhejiang province, Zhejiang province should start from the following four aspects: put emphasis on the top level design; continue to improve the standards for approval and evaluation of variety; accelerate the breeding of high quality rice varieties;further deepen the extension and industrialization of high quality rice.
