[Method] The test carried out according to split plot design. 5 sowing dates( A1,A2,A3,A4,A5) and 4 sowing quantity( B1,B2,B3,B4) were arranged. [Result] With the delay of sowing date,wheat basic seedlings decreased,the highest group and the spike number also decreased,the difference of spike rate in different sowing times was small. Yield decreased in step significantly with delayed sowing date,especially A5. With the increase of the sowing quantity,basic seedlings gradually increased,the highest group gradually increased,the yield increased gradually,and the spike rate gradually reduced,the spike number increased and then decreased,inverted V type. From the interaction of sowing date and sowing quantity,the yield of combination of early sowing and high quantity was high,and that of late sowing was very low. [Conclusion] Luo Mai 18 in southern Henan sowing in October 10- 20 was suitable,and the sowing amont of 187. 5- 225. 0kg / hm2 was more appropriate. And the yeilld of October 10 th planting and sowing rate of 187. 5kg / hm2 was the highest.Read More
