为探索\\\"甬优12\\\"杂交稻在绍兴的生长特点,掌握预防稻曲病关键时期,于2012年开展了\\\"甬优12\\\"单季稻不同移栽方式下的生长特点观察。结果表明,\\\"甬优1 2\\\"杂交稻在绍兴县种植全生育期达1 8 9~1 9 4 d,属生育期特别长的品种。\\\"甬优1 2\\\"出叶速率在移栽后1 0 d内机插慢于人插,移栽后11 d机插快于人插,快速出叶期机插比人插长10 d左右。预防稻曲病关键时期:机插为插种后67 d、人插为插种后66 d。达到有效穗苗数时间:机插为插种后27 d、人插为插种后20 d。
In order to explore the growth characteristics of \"Yongyou 12\" hybrid rice in Shaoxing and master the key period of preventing false smut in 2012, the growth characteristics of \"Yongyou 12\" single-season rice under different transplanting methods were observed. The results showed that the \"Yongyou 12\" hybrid rice was planted in Shaoxing County for a total growth period of 1889-194 days, which is a species with particularly long growth period. \\ \"Yongyou 1 2 \\\" leaf out rate in 10 days after transplanting machine inserted slower than human insertion, transplanting 11 d machine inserted faster than human insertion, fast leaf outage machine inserted than the human 10 d about. Prevention of the key period of false smut: Machine insertion was 67 days after intercropping and intercalary insertion was 66 days after intercalary. Time to reach the effective ear seedlings: Machine inserted for 27 days after intercourse, intercourse inserted 20 d after the insertion.
