对早地裸燕麦光合作用与产量形成生理指标的研究结果表明:旱坡和旱滩地裸燕麦的合理叶面积系数分别为2和2.5—3,构成每亩的最高产量分别为109.15公斤和166.25公斤;光合强度最高值出现在孕穗期,其值为13—24mg/dm~2/小时;旱坡和旱滩地裸燕麦的总光合势分别以3万—3.5万m~2·日和5万—7万m~2·日的产量较高;裸燕麦的净光合生产率为 7—10g/m~2日的产量较高.通过对上述生理指标的阐述,为旱地裸燕麦丰产栽培提供了理论依据.
The results of physiological indexes of photosynthesis and yield of early oats showed that the reasonable leaf area coefficients of bare oats on dry land and dry land were 2 and 2.5-3, respectively, and the highest yield per acre was 109.15 kg and 166.25 kg ; The highest photosynthetic intensity appeared at the booting stage, the value of which was 13-24mg / dm ~ 2 / h; the photosynthetic potential of bare oats on the dryland and the dry land were respectively 30000-35000 m 2 · day and 50,000- The yield of naked oats was 7-10g / m ~ 2, and the yield was higher than that of the other two oats. The elaboration of above physiological indexes provided the theoretical basis for the high yield cultivation of dry oats .
