Effect of different enclosure models on flexible nutrition of Seriphidium transiliense

The changes of soluble carbohydrate, starch, crude protein of Seriphidium transillense under different enclosure models were analyzed in Ashili country in Xinjiang from May to November 2006.The results showed that the change regulation of storage substance was a similar pattern under different enclosure models. Soluble carbohydrate contents in S. transillense root showed a single peak trend, and the highest contents for perennial enclosure, forbidden grazing land and continual grazing land were 53.43 mg/g, 36.77 mg/g, and 32.63 mg/g respectively; the starch contents appeared reverse V . The crude protein contents showed downupdown trend, and the differences existed in the emerging time and duration of the peak. Contents of soluble carbohydrate, starch and crude protein were significantly different among three enclosure models（P＜0.01）, and the order of soluble carbohydrate was perennial enclosure＞forbidden grazing ＞continual grazing; the order of starch was perennial enclosure＞continual grazing＞forbidden grazing; Crude protein was the highest in continual grazing land.
