摘要
在缙云试验点开展喷微灌条件下不同年降雨量对典型经济作物灌溉定额的影响研究,以期为区域性经济作物的水分高效利用提供理论基础。研究结合了2010—2013年的观测资料,并对试验结果进行分析,得出不同年降雨量与典型经济作物的灌溉定额成线性关系,同时对比分析了各种灌溉方式的节水率和增产效益。
Studies were carried out in Jinyun on the effect of different annual rainfalls on irrigation quota of typical economic crops under spray micro- irrigation conditions,with a view to providing theoretical basis for the efficient water use of regional economic crops.The research combined the observation data from 2010 to 2013,and analyzed the experimental results,got a linear relationship between different annual rainfalls and irrigation quota of typical economic crops.Meanwhile,the water- saving rate and yield benefits of various irrigation methods were comparatively analyzed.
