不同育插秧方式对水稻甬优2640秧苗农艺性状及产量的影响

Effects of Different Cultivation and Transplanting Methods on Agronomic Characters of Seedlings and Yield for a Rice Cultivar Yongyou 2640

为探明不同育秧与插秧方式对水稻秧苗农艺性状及产量的影响,以甬优2640为供试材料,研究毯苗机插、钵苗机插和钵苗有序抛秧3种育插秧方式下水稻秧苗农艺性状、漏秧率及产量表现等的差异。结果表明,水稻甬优2640钵苗机插的根长、根数和基茎宽等秧苗农艺性状较毯苗机插秧苗的表现更好,漏秧率降低,产量明显增加;钵苗有序抛秧秧苗的农艺性状表现介于钵苗机插与毯苗机插的秧苗之间,产量较毯苗机插略有增加。

In order to investigate the effects of different seedling cultivation and transplanting methods on agronomic traits of rice seedling and yield,Yongyou 2640 was selected as the test material to study the differences of agronomic traits,seedling leakage rate and yield performance of rice seedlings under three different seedling cultivation and transplanting methods:blanket seedling machine transplanting,pot seedling machine transplanting and pot seedling orderly throwing.The results showed that compared with blanket seedling machine transplanting,the root length,root number and base stem width of pot seedling machine transplanting for rice cultivar Yongyou 2640 appeared better seedling quality,lower seedling leakage rate and higher grain yield.The rice seedling quality of pot seedling orderly throwing performed between pot seedlingmachine transplanting and blanket seedling machine transplanting,and the yield was slightly higher than that of blanket seedling machine transplanting.
