Abstract
[Objective]To research the effects of different planting and breeding modes on the yield and physiological characteristics of hybrid rice.[Method]Dry nursery and annual planting,carpet seedlings and machine transplanting and pot seedling and machine transplanting were a-dopted.The yield and physiological characteristics of Huiliangyou 996 and Yongyou 8 were researched.[Result]Pot seedling and machine trans-planting had the highest yield,followed with dry nursery and annual planting;and carpet seedlings and machine transplanting had the lowest yield. The three modes had extremely significant differences.Population stem tillers were the most at transplanting stage by dry nursery and annual plant-ing,but it was the most at tillering stage by carpet seedlings and machine transplanting,indicating that the latter had the longest tillering stage and the greatest maximum seedlings.Finally,carpet seedlings and machine transplanting had the most ears.Single leaf weight and apparent operation volumn of the three modes at tillering stage and mature stage from big to small were in the order of pot seedling and machine transplanting,dry nursery and annual planting,carpet seedlings and machine transplanting.Dry weight per seedling and population dry weight at transplanting stage were in the order of dry nursery and annual planting,pot seedling and machine transplanting,carpet seedlings and machine transplanting,that at tillering stage was in the order of pot seedling and machine transplanting,dry nursery and annual planting,carpet seedlings and machine transplan-ting,showing extremely significant differences.[Conclusion]This research provided theoretical basis for the super-high-yielding cultivation of hy-brid rice.关键词
