摘要
为了研究贡井地区水稻适宜移栽叶龄,采用对比试验,分析了不同移栽叶龄对水稻主要农艺性状及产量的影响。结果表明,水稻最佳移栽叶龄为4.6叶,单产9.0t/hm^2以上,适宜移栽叶龄中苗为3.5~5叶,多蘖大苗为5.1~7.8叶。
To explore transplanted rice at appropriate leaf age in Zigong,effects of transplanting at different leaf age on main agronomic traits and yield of rice was comparatively studied.The results showed that the best transplanting time is 4.6 leaf age,the yield of rice even above9.0t/ hm^2,and the appropriate transplanting time for medium seedlings are 3.5- 5 leaf age,older seedlings with tellers are5.1- 7.8 leaf age.
