Effects of Different Cultivation Methods on Yield and Dry Matter Production of Late Hy-brid Rice
摘要
Abstract
The yield, dry matter accumulation and growth characteristics of medium maturing late japonica rice variety Ning 81 were studied under different cultivation methods. The results showed that the yield of Ning 81 with hand-transplanting was higher than that of the other two cultivation methods. Hand-transplanting and machine-transplanting rice got higher spike rate of over 70%. The tiller spikes on the main stem 4 to 7 leaf position had more contribution to yield in throw seedlings and machine-transplanting rice, while the 6 to 8 leaf position had more contribution to yield in hand-transplanting rice. Throw seedlings had more dry matter accumulation in jointing stage than others, in jointing to heading stage, hand-transplanting method performed best, in heading to maturity stage, ma-chine-transplanting method had higher dry matter accumulation.关键词
