Grain Potential Productivity of Cultivated Land in Baoji, Shaanxi Province, China

Abstract:

The natural quality index and the utilization quality index in agricultural land classification are essentially two kinds of grain potential productivity, which, we name natural potential productivity and utilization potential productivity of cultivated land respectively. Based on this, we calculated the natural potential productivity and utilization potential productivity of cultivated land in Baoji. Both of them are 980.336×104t and 587.299×104t respectively. The natural potential productivity per unit area is 26.905t/hm2 and the utilization potential productivity per unit area is 16.118t/hm2. The natural potential productivity of Chencang District is 172.956×104t, the maximum, that of Taibai County 10.744×104t, the minimum. In terms of the utilization potential productivity, that of Fengxiang County is 105.033×104t, the maximum, and that of Taibai County 6.795×104t, the minimum. But natural potential and utilization productivity per unit area of Fufeng County are 37.954t/hm2 and 25.011t/hm2 respectively, the maximum, and those of Linyou County 11.672 t/hm2 and 7.095t/hm2 respectively, the minimum.
