- 摘要:
- 为探明水稻群体冠层内光分布规律,以寒地水稻品种龙稻5号、松粳9号和牡丹江19为试材,研究了不同肥力水平下的群体冠层光环境。结果表明:龙稻5号、松粳9号分蘖前期叶面积指数较小,漏光严重,齐穗后叶片挺直,群体内部的光照强度增加,叶片衰老缓慢,群体维持较大的光合面积的时间较长,有利于植物的净光合速率积累,产量潜力较高。在高肥条件下,叶片有向披散方向发展的趋势,群体光合量提高。
- Abstract:
- In order to prove light distribution of population canopy,taking cold region rice varieties Longdao 5,Songjing 9 and Mudanjaing 19 as test materials,the light environment with different fertilization amount were studied.The results showed that the leaf area indexes of Longdao 5 and Songjing 9 were so small that had light leak seriously at early stage of growth.After full heading stage,the leaves were straight,the light intensity of groups increased,leaf senescence was slow,which is conducive to the accumulation of plants net photosynthetic rate and had high yield potential.Under the condition of high fertilizer,the leaf tended to divergent and photosynthate improved.
