Under conditions of pure sowing and sowing of a grass-legume mixture consisting of Leymus (=Aneurolepidium) chinensis and Hedysarum mongolicum, studies were carried out on the effects of deep ploughing (30cm) and shallow ploughing (15cm) on a degraded grassland in the Stipa steppe in the Alihe Area located in the high latitude winter cold zone of Chine. The data from the present experiment suggest that the sowing of a mixture of L. chinensis and H. mongolicum with deep ploughing is most suitable for increasing the photosynthetic efficiency, dry matter production of plants and the production of several nutrient substances in comparison with other experimental treatments such as pure sowing of L. chinensis with deep or shallow ploughing, pure sowing of H. mongolicum with deep or shallow ploughing, sowing of a mixture of L. chinensis and H. mongolicum with shallow ploughing, and degraded Stipa baicalensis-forb grassland (control treatment). Thus a new method of establishment of artificial grasslands in the winter cold zone of China by mixed sowing with deep ploughing was developed.
