摘要
为了确定各种废料对于荒漠草原退化草地植被特征的实际影响,本文在一片较为典型的荒漠草原退化地点,使用有机磷酸二铵、尿素以及过磷酸钙,展开草地植被特征的影响实验。试验的结果表明,有机磷酸二铵对于荒漠草原退化草地植被密度、盖度以及生长量的影响最为显著,而且实际影响远比对照影响更加理想,将其对植被特征的影响与其他两种肥料的影响相比,可以发现有机磷酸二铵的效果更加显著。因此,在对荒漠草原退化草地展开施肥治理时,最好选择有机磷酸二铵作为主要肥料。
In order to determine the actual effects of various wastes on the vegetation characteristics of desert and degraded grassland,experiments were carried out in a typical desert grassland degradation site by using organic diammonium phosphate,urea and superphosphate.Through the analysis of the results of this experiment,it can be determined that in this experiment,DAP has the most significant effect on the vegetation density,coverage and growth of degraded grassland in desert steppe,and the actual effect is far more ideal than the control effect.Compared with the other two fertilizers,DAP has a more significant effect on the vegetation characteristics.Therefore,it is better to choose DAP as the main fertilizer when applying fertilizer to the degraded grassland of desert steppe.
