在小麦高产栽培中,人们越来越重视光合能力的提高。但在大田生产条件下,系统比较不同产量水平下的小麦光合能力的差异,以及农业措施对光合能力的影响,还缺少系统深入的研究。为此,我们利用红外线CO_2分析仪分析测定了不同生产条件下小麦旗叶的光合强度,主要结果如下。
In high-yield wheat cultivation, people pay more and more attention to the improvement of photosynthetic capacity. However, under the conditions of field production, the differences in photosynthetic capacity of wheat under different yield levels and the effects of agricultural practices on photosynthetic capacity were also systematically investigated. Therefore, we use the infrared CO_2 analyzer to analyze the photosynthesis of wheat flag leaf under different production conditions, the main results are as follows.
