摘　　要：针对江苏沿海垦区的土壤特点,以东台市为例,采取不同矿化度水源对大棚种植的苏椒5号、洛椒4号98A和江椒2号进行滴灌试验,分析水源矿化度对灌溉水量、总产量、水分生产率与经济效益等方面的影响。结果表明:随着灌溉水源中矿化度增加,三种青椒的灌溉总用水量均显著增加,且盛果期灌溉用水量最大;三种青椒的总产量和水分生产率均随着水源矿化度的增加而下降,而青椒尾果期产量占总产量中的比重随之呈增加趋势;不同矿化度水源灌溉条件下,三种青椒的经济效益均表现为深井水>混合井水>浅井水。在江苏沿海垦区进行大棚青椒的滴灌种植,最适宜选择的品种为苏椒5号,若从经济增加值考虑,建议采用混合井水(1∶1)灌溉。Taking the characters of soil in the reclaimed land along the coastal areas of Jiangsu Province into consideration, impact analysis of different water mineralization degree on green peppers No. 5, No. 4 98A and No. 2 by drip irrigation are conducted with Dongtai as an experiment site, such as irrigated water volume, total yield, water productivity and economic benefits. The results show that the total amount of irrigated water use by these three vegetables all increases along with the adding of water mineralization degree and water demand is the highest during the full fruit period; total yields and water productivity of there type of vegetables decrease along with the adding of water mineralization degree and the percentage of yield during the ]ate fruiting period in the total also increases; the economic benefits of three types under different water mineralization degree decrease successively from deepwater well to mixed water well and then shallow water well. Green pepper No. 5 is the most suitable one for this area with drip irrigation. Mixed water （1：1） is recommended for irrigation from the point of economic added value.
