The contribution of potassium to crops is not only reflected in the quality, but also more in the contribution to the yield. 130 groups are located in the middle of the Kuitun reclamation area, the northern foot of the Tianshan Mountains and the alluvial-alluvial plain in the upper reaches of the Kuitun River. The southern part overflows with fan-shaped groundwater and serves as an oasis irrigated area. In 2008, the whole group of farmland soil available potassium average 382mg / kg, compared with 452mg / kg in 1998
