摘要
利用3年马铃薯生育期间发蒸腾量实测数据进行了各旬作物系数计算。根据作物需水量与天然降水同期的关系,确定了不同保证率马铃薯作物缺水量。分析主产区9县(市)5—9月多年系列连续10 d以上无降水次数、发生的月份,提出了喷灌节水灌溉条件下生育期灌水定额和灌溉定额,可为马铃薯主产区农业灌溉提供理论依据和科学指导。
the paper calculates the crop coefficient of ten days by using the measured data of transpiration during the three-year potato growth.According to the relationship between crop water demand and natural precipitation,the water shortage of potato crops with different assurance rates was determined.The number of precipitation free and months in the main production area of 9 counties(cities)in May September for more than 10 days in succession were analyzed.The irrigation quota and irrigation quota in growth period under the condition of water-saving irrigation were put forward,which could provide theoretical basis and scientific guidance for agricultural irrigation in potato main production area.
