为了明确我省光壳陆稻的光温反应,将收集到的十二个品种(其中外国种两个作对照)。从2月15日至8月15日共播7期,现将试验结果列于表一。根据表一,可以看出如下的趋势: 1.生育日数的长短和积温的表现基本上相一致。 2.生育日数随着温度的逐渐增高而逐步减少。7月以后,气温由高转向低,生育日数却又随之增加。6号地糯、元阳地糯、金 In order to clarify the light-temperature response of light-shelled upland rice in our province, twelve varieties (of which two are foreign ones) will be collected.
