In oder to protect the natural desert plant Zygophyllum xanthoxylum (Bunge) in the western Ordos national nature reserve according to a plan, and to maintain its ecological niche, by taking Z. xanthoxylum growth recession as the research object, six different stubble heights (-3(under ground), 0(on ground), 3(over ground), 5(over ground), 10(over ground), 15cm(over ground)) were selected, to investigate the effects on its vegetative growth. It is shown that, ① For different stubble heights, the overall effect with respect to the number of branches, the length and the diameter of Z. xanthoxylum of the different brush is better than that of the same brush;② For different stubble heights, its height grows higher than the control, the highest is that with the stubble height of 3cm, 3.64 times as the control;the number of new branches is larger than that of the contrast, with a difference of up to 23.08 times at the stubble height of 3cm for the different brush, and 5.45 times for the same brush;The diameter of new branches is larger than that of the contrast, with a difference of up to 1.58 times at the stubble height of 3cm for the different brush, and 1.25 times for the same brush;The length of new branches is larger than that of the contrast, with a difference of up to 2.63 times at the stubble height of 3cm for the different brush, and 1.98 times for the same brush;③ The membership function analysis shows that for the different brushes, the vegetative growth of Z. xanthoxylum is in the following order according to the stubble height: 3cm>0cm>-3cm>10cm>15cm>5cm;For the same brush, the order is 10cm>-3cm>5cm>0cm>15cm>3cm.
