Effect of Different Transplanting Seedling Ages on Grain Yield of Rice

In order to understand the impact of different rice seedling age transplanting methods on yield and economic benefit.We use Neixiang 8518 as test materials,small rice seedlings(3-4leaves)line and large seedlings(7-9leaves)transplanting large area controlled field trial experiments was studied.The results showed that:from a practical yield,the yield of large seedlings was 9381.0kg/hm2,greaterer than small rice seedlings transplanting,but the difference was not significant.From the economic analysis,the small seedling line mode have a fewer input costs,although the yield is slightly lower,because of reduced the artificial cost,ultimately improve the economic efficiency.The small seedling transplanting seedlings line ratio efficiency 3663.0Yuan/hm2,up 24.2percent than the large seedlings.
