摘要
以"协优9308"为对照,对2个弱感光杂交籼稻品种"昌优70"和"赣亚1号"在杭州的适宜播种期进行了试验。结果显示:不同播种期处理间产量、千粒重、株高、穗长4个性状差异达极显著水平(P<0.01);"昌优70"于4月20日播种和"赣亚1号"5月20日播种的产量最高,分别达8730.0 /hm2和8382.5 /hm2。
The suitable sowing dates of two weakly photosensitive hybrid indica rice varieties—'Changyou 70'and 'Ganya 1' were tested by using 'Xieyou 9308' as check. The results showed that the differences in yield, 1000-grain weight, plant height and spike length of rice among different sowing date treatments were very significant (P<0.01); among 3 sowing date treatments, the yields of 'Changyou 70' sown on April 20th and 'Ganya 1' sown on May 20th were the highest, and reached 8730.0kg/hm^2 and 8382.5kg/hm^2 respectively.
