The main nutrient contents in twigs and leaves of 5 psammophyte shrubs, which including Caragana intermedia, C. korshinskii, Hedysarum scoparium, H. laeve and Salix psammophylla were analyzed and determined. The results showed that the crude protein contents had a trend to decrease with growing stage, the peak values of C. intermedia, C. korshinskii and Salix psammophylla were appeared in blooming stage, but fibre matters (NDF, ADF and lignin) contents were lowest in post fruiting vegetative stage. However, the peak values of H. scoparium and H. laeve were appeared in vegetative stage and lowest in yellowing stage.
