不同播种期对单季杂交稻“中浙优1号”产量及生育期的影响研究

Effects of Different Sowing Date on Yield and Growth and Developmental Duration of Single Cropping Hybrid Rice "Zhongzheyou 1"

试验结果表明,“中浙优1号”作单季晚稻种植,5月15日至6月4日播种均可正常成熟。在本试验条件下,以5月25日播种,即秧龄35d处理的产量最高。

The test results showed that under the same condition of planting as single cropping late rice, ＂Zhongzheyou 1＂ could normally mature when sowed from May 15th to June 4th. Under the testing condition, the yield of ＂Zhongzheyou 1＂ with 35 days＇ seedling age which was sowed on May 25th was the highest among different sowing date treatments.
