摘要：
Investigations were conducted into optimal water supply regimes, which encourage full use of the water provided. These were undertaken in a greenhouse experiment at the University of Nijmegen. The aim was to improve understanding of how root foraging characteristics respond to different water application patterns. Measurements were made for Oil Seed Rape( Brassica campestris). which is already widely cultivated in China. Four water supply patterns were implemented, namely fixed patch(T1), alternate patch (T2), or even water supply with same amount of water. Alternate wetting produced the highest WUE, though there were only small differences between values for T1, T2 and T3.
