- Abstract:
- Through analysisng three year’s data of flax’s productivity and its water use characters.the results show: The flax’s yield could reach at 104kg/mu in normal rainstyle of year, and its WUE was 0.31kg/mm, evaporation and plant transpiration (ET) ranged 280-320mm.The mean depth of water consulmption was 1.9m, the highest was 2.8m.its soil water use efficiency was 42.8%.At present condition, by fertilized 0-15kg/mu, flax yield would be increased by added fertilizer.In flax’s life, the rainwater account for 56% of total ET.soil water by 44%, which 94.4% was from within 0-2m depth.The total ET consist of 14.9% in former stage, 58.3% in middle stage, 26.8% in later stage.The highest ET was in the filling stage which was 4.74mm/d.From water balance, the middle stage would be serious by water lack, the balance would be 68.4% of total ET.
