摘要
在全幅播种条件下 ,对小麦的茎叶生态系统和光能利用进行了研究。结果表明 ,小麦群体的株间透光率、净光合强度、光合生产率及光能利用率等较之条播都有明显增加 ,“茎 -叶”生态系统得到改善 ,增产效果十分显著 。
The stem-leaf ecosystem of spring wheat and solar energy efficiency were studied in all film-mulched condition. The results showed that the light leak rate, net photosynthetic rate, photosynthetic productivity, solar energy efficiency of wheat population and stem-leaf ecosystem had significantly improved in the all film-mulched condition. The wheat yields increased remarkably. The all film-mulched cultivation of spring wheat became one of an important way in improving wheat yield and quality in the Hetao irrigated areas of Inner Mongolia.
