摘要
研究表明,甜菜育苗移栽对块根根系发育有一定影响,但与直播比差异不明显,根形直播好于专用纸筒,专用纸筒好于其他载体;不同断根长度处理,除截断载体1/2处理外,其余各处理根形间虽然有差异,但断根长度与根形间无明显相关性;同一载体不同移栽期,以适期移栽(5月1～5日)根形、产质量都好于其他移栽期;专用纸筒苗根形好于营养钵苗,但产质量营养钵育苗明显优于专用纸筒苗.
The study has shown that there was certain effect on root system development of raising seedling and transplanting, but have no significant difference which compared with direct sowing, root type of direct sowing was better than other carrier treatments, different root length of cutting, the root type have difference between other treatment except cutting 1/2 root length of carrier, there was no significant difference of correlation between the length of cutting and root type, the same carrier in different transplanting date, the optimum date was 1 ~ 5 May, the root type, yield and quality were better than other transplanting date, the root type of other treatment was better than nutrition.but the yield and quality of nutrition pot were better than others.
