| Abstract: |
| A field experiment was conducted to determine the effects of mode 150 cm(DX1), mode 120 cm(DX2), mode 80 cm(DX3), film-covered double-furrow(DX4), flat film-
covered(DX5) and traditional cultivation(CK) six micro-water-harvesting techniques on soil water use efficiency and grain yield of mung bean in Shenmu, the northern of Shaanxi. The results show that there are obvious effects of micro-water-harvesting techniques compared with traditional cultivation (CK). They can significantly increase water storage capacity in the 0～40 cm soil layer, as well as speed up growth and leaf area, biomass and chlorophyll content. The DX4 has the best effect, in which the grain yield and water use efficiency increase by 24.5% and 32.88%, while DX5, DX3, DX2 and DX1 are also up to remarkable level. Therefore, the micro-water-harvesting techniques have large water storage capacity and can increase grain yield and water use efficiency. |
