小麦花后叶片结构与功能的营养调控研究

Study on nutrient regulation to leaf structure and function after wheat blossom.

试验研究复合营养调控剂活力王 (HLW )对小麦叶片结构与功能的影响结果表明 ,小麦孕穗期叶面喷施 1次活力王可有效改善叶片结构与功能 ,旗叶面积扩大 3.2 % ,倒 2叶和倒 3叶面积减小 1.8%～ 7.1% ;小麦旗叶叶绿素含量增加 19.17% ,蛋白质含量增加 5 1.7%。光合强度增加 75 .79%。小麦代谢活力的提高延缓了叶片衰老进程。

Effects of HLW (Huoliwang),a new compound nutriments playing a role of adjustment and control, on the leaf structure and function after wheat blossom show that HLW sprinkled on leaves during boot stage of wheat can improve effecti vely the leaves' structure and function. The area of flag leaf is expanded by 3. 2%, however, the areas of the second and third leaves are reduced by 1.8%～7.1 %;chlorophyll content of flag leaf increases by 19.17%,the protein content in creases by 51.7%and photosynthetic rate increases by 75.79%.In a word, the tec hniques improve the metabolism vitality and retard the progress of leaf senescen ce.
