不同行距和播量对重穗型高产冬小麦生物学性状的影响

Effect of different row space and seeding quantity on biological characteristics of heavy panicle type high yield winter wheat

以新培育的两个大穗大粒小麦品系为材料,通过对参试材料的生物学性状等指标测定比较,研究了不同播量和行距配置对重穗型高产冬小麦生物学性状的影响。结果表明,播量控制在每公顷450万基本苗和16.7cm行距配置模式下,冠层温度、旗叶的叶绿素含量、倒二叶的叶绿素含量均优于其余配置处理,播量控制在每公顷450万基本苗下的各处理有效穗数高于其余播量,即每公顷450万基本苗处理优于其余处理。

With two new fostered wheat strains as materials,determination and comparison were made of their physical and biological characters to study the influence of different sowing quantity and row spacing on physical and biological properties of different wheat varieties in different local donditions.The results show that,in 4.5 million seeding quantity and 16.7 cm row space of planting configuration model,the canopy temperature,the flag leaf chlorophyll content,the penultimate leaf chlorophyll content and the number of ears per acre are all better than other cultivation models.
