杂交水稻中浙优1号高产高效技术途径分析

“中浙优1号”是由中国水稻研究所与浙江省杂交水稻种业有限公司合作育成的单季杂交晚籼稻新组合，是台州单季杂交晚稻的一个主要组合。通过近年来的种植考查显示，中浙优1号株型较好，植株挺拔、剑叶直挺、分蘖力强、长势旺、穗大粒多、结实率高、后期青秆黄熟，功能叶的功能期较长，无明显早衰现象，灌浆历期较长，两次灌浆不明显。该组合属感温性组合，齐穗期随播种期的推迟而推迟，一般生育期为133—139d。据2002年浙江省农科院植物保护与微生物研究所接种鉴定结果，

Analysis of High Yield and Efficiency Technique in Hybrid Rice Zhongzheyou No.1

To understand the high yield and efficiency technique in hybrid rice Zhongzheyou No.1, we conducted the correlation analysis, regression analysis and path analysis of hybrid rice Zhongzheyou No.1 based on the data of its ear, grain and weight at different yield levels. From this study, we put forward the high yield and efficiency technique in Zhongzheyou No.1: on the basis of certain effective ear number, filled grains per ear should be mainly targeted with a consideration to 1 000-grain weight.
