【摘要】 利用岷县耕地资源管理信息系统和地力评价成果,选取9个影响马铃薯生长的评价因子,将岷县马铃薯适宜性生长区域分为高度适宜、适宜、勉强适宜、不适宜4个等级。其中高度适宜区面积达21 665.24hm2,占全县总耕地面积的43.27%;适宜区面积为21 567.96 hm2,占全县总耕地面积的43.08%;勉强适宜区面积为5 146.49 hm2,占全县总耕地面积的10.28%;不适宜区面积为1 688.5 hm2耕地,占全县总耕地面积的3.37%。高度适宜区主要分布在洮河沿岸的中寨镇、梅川镇、茶埠镇、岷阳镇、十里镇、清水乡、西寨镇、寺沟乡、禾驮乡,宜建立马铃薯产业化生产区,特别是脱毒种薯繁育区及专用型薯生产开发区。更多还原

【Abstract】 Using the Minxian Land resources management information system and productivity evaluation results, 9evaluation indices of ecological suitability are selected to divide into highly appropriate,suitable,appropriate and inappropriate reluctantly. The highly regarded area is 21 665.24 hm2,accounting for 43.27% of the total arable land in the county;Suitable area is 21 567.96 hm2,accounting for 43.08% of the total arable land in the county;Barely suitable area of 5 146.49 hm2,accounting for10.28% of the total arable land in the county;No suitable area of 1 688.5 hm2 cultivated land,accounting for 3.37% of the total arable land in the county. the highly appropriate area mainly distributed in the village along the taohe river,zhongzhan town,meichuan town,chafu town,minyang town,shili town,qingshui town,xizhai town,sigou town,hetuo town. These towns are suitable for the potato industrialization production area,especially the detoxification potato breeding areas and special development of potato production.更多还原
