垄厢栽培对水稻结实期剑叶生理性状和产量的影响
Effects of ridge-bed cultivation on physiological characteristics of flag leaf and grain yield during grain filling
摘要
Abstract
In this study, physiological characteristics of flag leaf and grain yield during grain filling were investigated under conventional cultivation (TO) and different ridge cultivations including narrow ridge with terrace (T1), wide ridge with terrace (T2) and wide ridge with bed (T3) for rice varieties Y Liangyou 1, Huanghuazhan and Shanyou 63.The results showed under Tl and T2 cultivation, flag leaf chlorophyll content of rice was high with slowed leaf aging and higher net photosynthetic rate, which was conducive to the improvement of the protective enzyme activity to maintain normal cell metabolic.Under TO and T3 cultivation, rice flag leaf chlorophyll content was low with fast aging, and the enzyme activity decreased by 24%-44%, 28%-46%, respectively.It was showed that grain yield in T1 cultivation was the highest, followed by T2 and T3 cultivation, grain yield of T3 cultivation was slightly higher than that of the T0 cultivation, but the difference did not reach statistical significance.关键词
