- 摘要:
- 为明确北方荒漠草原过渡地带县域内的农作物种植制度调整方向,本研究基于2012-2021年陕西省榆林市定边县各乡镇的农作物生产数据,分析了近十年该县所有农作物和粮食作物的种植面积变化,以及各乡镇粮食作物的种植面积、产量和单产状况。结果表明:定边县的农作物以粮食作物为主,其中玉米、荞麦和马铃薯是三大主要粮食作物。进一步对各乡镇三大主要粮食作物的种植状况分析,并结合定边县农业用水资源分布特征,建议增加北部滩区水资源比较丰富的白泥井镇、郝滩镇、堆子梁镇和石洞沟乡的玉米种植面积,压减南部山区玉米种植面积,改种荞麦等耐旱耐寒作物;重点压减荞麦单产水平较低的红柳沟镇、樊学镇和张崾先镇的荞麦种植面积;增加北部滩区堆子梁镇、盐场堡镇和石洞沟乡的马铃薯种植面积,优先在种植面积较大的白泥井镇、砖井镇、贺圈镇开展马铃薯和玉米、荞麦之间的轮作种植,同时减小贺圈镇和砖井镇的荞麦种植面积,为马铃薯轮作模式的开展提供更大的空间。
- Abstract:
- In order to clarify the direction of the adjustment of crop planting system in the counties of the northern desert steppe transition zone, based on the crop production data of various villages and towns in Dingbian County, Yulin City, Shaanxi Province from 2012 to 2021, this study analyzed the change of planting area of all crops and grain crops in the county in the past decade, as well as the planting area, yield and unit yield of grain crops in various villages and towns.The results showed that the crops in Dingbian County are mainly grain crops, among which maize, buckwheat and potato are the three major grain crops. Further analyze the planting situation of the three major food crops in each towns, and in combination with the distribution characteristics of agricultural water resources in Dingbian County, it is suggested to increase the corn planting area in Bainijing Town, Haotan Town, Duiziliang Town and Shidonggou Township, which are rich in water resources in the northern beach area, reduce the corn planting area in the southern mountain area, and change to grow drought and cold resistant crops such as buckwheat; Focus on reducing the planting area of buckwheat in Hongliugou Town, Fanxue Town and Zhangyaoxian Town with low yield of buckwheat; Increase the potato planting area in Duziliang Town, Yanchangbu Town and Shidonggou Township in the northern beach area, give priority to the rotation planting between potato and maize and buckwheat in Bainijing Town, Zhuanjing Town and Hejuan Town with large potato planting area, and reduce the buckwheat planting area in Hejuan Town and Zhuanjing Town to provide more space for the development of potato rotation mode.
