- Abstract:
- In order to select reasonable water-harvesting and soil conservation measures in young plantations of Prunus sibirica Lam. in gneiss rocky mountainous area of north China, growth, physiological, and soil moisture evaluation indicators such as ground diameter, tree height, volume, shoot length, net photosynthetic rate, chlorophyll content, and soil water content were used to indicate the effect of different measures on Prunus sibirica L. in Pingshan County, Hebei Province in 2008. The micro-topography water-harvesting and soil conservation measures include wing-style fish-scale pits + soil absorbent polymers + stone-mulching (YY+B+S), wing-style fish-scale pits + soil absorbent polymers + straw-mulching (YY+B+J), wing-style fish-scale pits + soil absorbent polymers (YY+B), wing-style fish-scale pits + stone-mulching (YY+S), wing-style fish-scale pits + straw-mulching (YY+J), wing-style fish-scale pits (YY) only, also a group of Prunus sibirica L. without any treatment were included as the control treatment(CK). The result showed that: (1) soil moisture could be improved by the water-harvesting and soil conservation measures by 22.4% to 61.8% and 28.53% to 106.25% in a whole growth season and a rainfall cycle, respectively; (2) the growth of Prunus sibirica L. such as ground diameter, tree height, volume, and shoot length could be enhanced through the above treatments by 26.07%, 117.87%, 443.83%, and 84.04%, respectively compared with CK; (3) the net photosynthetic rate, chlorophyll content of Prunus sibirica L. increased by 3.16%~153.56%, and 25.24%~128.73%, respectively, compared with CK; (4) considering the factors above, also with the economic factor, YY+S and YY+J were recommend as the available, economical, convenient, and adaptable water-harvesting and soil conservation measures for Prunus sibirica L. in gneiss rocky mountainous area.
