灌溉方法的可靠信息对于确定农业需水趋势是重要的。因此，作者在2011年期间进行了一项研究，以收集2010年种植者用于灌溉作物的灌溉方法的信息。将结果与早期调查进行比较，以评估种植和灌溉方法的趋势。编制了一份单页调查表，按作物和灌溉方法收集灌溉土地的信息。调查问卷邮寄给了加州的1万名种植者，他们是从美国农业部国家农业统计局的5.8万名种植者名单中随机挑选出来的，不包括水稻、旱地和牲畜生产者。从1972年到2010年，果园种植面积从15%增加到30%，葡萄园种植面积从6%增加到15%。蔬菜种植面积保持相对稳定，而大田作物种植面积从灌溉面积的67%下降到41%。土地灌溉量小...
AbstractReliable information on irrigation methods is important for determining agricultural water demand trends. The authors have therefore conducted a study over the course of 2011 to collect information on the irrigation methods that were used by growers to irrigate their crops in 2010. The results were compared with earlier surveys to assess trends in cropping and irrigation methods. A one-page questionnaire was developed to collect information on irrigated land by crop and irrigation method. The questionnaire was mailed to 10,000 growers in California who were randomly selected from a list of 58,000 growers by the USDA National Agricultural Statistics Service, excluding rice, dry land, and livestock producers. From 1972–2010, the planted area has increased from 15 to 30% for orchards and from 6 to 15% for vineyards. The area planted with vegetables has remained relatively static, whereas that planted to field crops has declined from 67 to 41% of the irrigated area. The land irrigated with low-volume ...
