摘要:
通过对不同播种期的秧苗素质的研究，确定最佳的播种时期。结果表明t第1叶鞘高与2叶长呈极显著的正相关（r -0. 8201’）l秧龄期和株高呈极显著正相关(R-0. 9367一)．结合2006年4 月份气温特点，并通过对第1叶鞘高、2叶长、根数、株高等性状分析，初步确认三江地区水稻最佳播种期是4月10—15日。
Abstract:
The relationship of different sowing time to quality of the rice seedling was researched to measure the optimal sowing date, the results showed that: The height of the lst leaf sheath presented extremely prominent positive correlation with the length of the 2th leaves ( r = 0. 8201’ ’ ) I Seedling age presented extremely prominent positive correlation with the plant height (R = 0. 9367’ ’ ). Ac- cording to the temperature characteristic in April of 2006, the traits analysis of the lst leaf sheath height, 2 leaf length, root numbers and plant height, April 10一15 was confirmed as the best sowing trme of rice
