为改变黄土高原的落后面貌,寻找一些耐瘠薄抗干旱,既能作饲料又能保持水土的优良牧草,我们近几年对黄土高原引种栽培的主要牧草进行了光合生产力、水分利用效率、固氮活力、抗逆性等生理指标测定,为进一步选择适生草种提供了科学依据.
In order to change the backwardness of the Loess Plateau and find some excellent pastures that are both poor and drought-resistant, both for feed and water and soil conservation, we conducted photosynthetic productivity, water use efficiency and nitrogen fixation in the main forages introduced and cultivated in the Loess Plateau in recent years. , Stress resistance and other physiological indicators, to provide a scientific basis for further selection of suitable grass species.
