摘要
为探讨不同穗型水稻黄叶、绿叶干物质积累与产量的关系,选择辽宁省不同穗型粳稻材料23个进行试验,其中有3个直穗型、5个弯穗型、15个半直穗型。采用随机区组设计,2次重复,分别在9月2日、9月9日、9月18日及10月5日取样,调查水稻黄叶重量、绿叶重量,成熟期调查产量。结果表明:在选择穗型及产量优势上应该选择直穗和半直穗型水稻品种。
In order to research the effect of dry matter accumulation and yield between the yellow leaf and green leaf with different panicle type,select 23 Japonica material to test,including three straight spike type,five curved panicle and 15 straight curved panicle.The test used randomized block design and 2 replicates,choose the sampling at Sept.2,Sept.9,Sept.18 and Oct.5 to research the weight of yellow leaves,weight of green leaves and yield of rice.The results indicated that erect spike panicle and semi-erect panicle varieties should be select form the advantage of spike type and yield.
