Description

Artemisia species are found in large areas of the Zhunger Basin, Tacheng Valley, Yili Valley, the northern slope of the Qulun mountains of Xingjiang ; the total area is larger than 6.67 million ha. The drought-enduring Artemisia has a high resistance to bad conditions and high protein and fat contents. Artemisia transiliensis Poljak at branched stage has 21.4 per cent crude protein, and the content of fat at the mature stage of seeds is 5.7 per cent. They are the best forages for lambs in early spring, autumn and winter, especially for fattening in autumn and milking in early spring. Horses and camels like grazing them also. Recently, most of the ranges in Xinjiang have been degraded. The forage yield declined by 30-70 per cent. The important task is to choose forage species adapted to arid ranges and sow them to improve the degraded ranges and fields given up by farmers. Nowadays, only Kochia prostrata (L) Schrad. is used for resowing on arid ranges in Xinjiang. Therefore, since 1985, both species Artemisia transiliensis Poljak and Artemisia rutifolia Stephe which are distributed widely on the arid range ofXinjiang have been studied; research into the ecological and biological characteristics for providing the techniques and methods of cultivation are carried out ; they can be reasonably utilized in the arid ranges. Nowadays these species cover over 4667 ha under range management.

Study on the Eco-Biological Characteristics and Utilization of Artemisia Growing on Arid Ranges
