| Abstract: |
| To provide technical support for the development of self-sustaining vegetation restoration model in the low elevation area of Helan Mountain. The effects of different artificial rainfall harvesting methods on soil moisture in Prunus mongolica root zone and physiological growth of P. mongolica in low elevation area of Helan Mountains were studied by setting three treatments, namely, mulching microtopography, mulching litter and mulch micro-topography + mulching litter, with no artificial treatment as the control. Results indicated that: (1) Among the effects of different artificial rain harvesting methods on soil moisture content in P. mongolica root zone, the most affected is the treatment of mulching micro-topography + mulching litter, followed by the treatment of mulching micro-topography, with an average soil moisture content of 11.91%, 10.64%. The soil moisture content of the control group was only 6.84%; (2) The rainfall collection treatment was able to increase the new growth of Mongolian lentil, with the largest new growth under A4 treatment, followed by A2, and A3 in the third place, and all of them had a greater increase in new growth compared with the control group A1.The rain harvesting treatment increased chlorophyll content of Mongolian lentil leaves in descending order of A4>A2>A3, with the average content increased compared with the control group;(3)Significant correlations were found between plant leaf area, new growth and soil water content under rainfall collection treatments, mainly mulching micro-topography + mulching litter (A4) and mulching microtopography A2); (4) Rainwater harvesting technology promotes the growth and development of Mongolian lentil scrub by regulating soil water conditions and increases chlorophyll content in leaves, thus improving the ability of Mongolian lentil to withstand drought. The rain harvesting techniques of "mulching microtopography + mulching dead litter" and "mulching microtopography" can be helpful for the self-sustainable vegetation restoration of Mongolian lentil scrub in the shallow mountainous areas of Helan Mountains. The artificial rainwater harvesting treatment can improve the soil environment and promote the growth of Mongolian lentil scrub, which is conducive to the reconstruction of the ecosystem and the sustainable development of vegetation restoration inLow elevation area of Helan mountain. |
