Abstract：In order to make best use of limited rainfall resource and improve crop yield ,a field con-trast experiment with two different planting patterns was carried out to study the effects of rain-harvesting planting on seeding rate and grain yield in arid terrace in semi arid loess hilly region . The results showed that ,there was difference in maze yield at the 1% significant level between single line planting flat and control flat ,and at the 5% significant level between double lines at one width ridge planting flat and control flat .The technology enhanced maize grain yield by 28.26% and 19.99% ,respectively compared with control flat .Meanwhile ,the grain yield showed an increasing trend with the increased planting density before the planting density reached a cer-tain value (4.8 × 104 seedlings per hectare) .It was concluded that the micro-harvesting tillage methods could efficiently improve the yield of crop .
