Effects of Different Sowing Dates on Economic Characters of Weakly Photosensitive Hybrid Indica Rice |
|
| Abstract: | 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. |
