油葵杂交种春播产比试验及适宜播期的确定

Experiment of Yield Compare of Oil Sunflower Hybrids and Determination of their Suitable Seeding Time in Spring

通过油葵产比、播期试验结果分析 ,新葵 6号 2 5 6 .6 7kg/ 6 6 7m2 ,较对照种 G10 1增产 11.82 % ,居参试种首位 ;同时提出春播种植油葵应选择生育期较长的品种 ,播期以 3月 2 5日至 4月 5日为宜 ,适播期内播种越早越好。

Experimental result of yield compare and seeding times were analyzed. it turned out that Xinkui NO.6 ranked first in all the participating hybrids with a yield of 256.67kg/667m 2 which was 11.82% higher than control G101. The resucts also indicated that hybrids with a long growth period should be chosen for spring sweing, the suitable seeding time between March 25 to April 5, and in this period the earlier the better.
