【摘要】 为了合理开发和安全利用海河流域环渤海低平原区浅层地下微咸水,以秋茬大白菜为研究对象,2010、2011年在河北临西灌溉试验站用0.72g/L(深层淡水)、2g/L(咸淡混合水)、3g/L(咸淡混合水)、4.3g/L(浅层微咸水)的微咸水进行田间灌溉试验,探求其对大白菜的产量和品质以及土壤盐分动态的影响。试验结果表明:不同矿化度微咸水灌溉的大白菜的品质之间没有差异。2、3g/L微咸水与0.72g/L淡水灌溉的大白菜的产量没有差异,但4.3g/L浅层微咸水直接灌溉比淡水灌溉产量降低,2年平均减产率9.0%。土壤含盐量随着灌溉水矿化度的提高总体出现增加趋势。更多还原

【Abstract】 For the sake of rational exploitation and safe utilization of the shallow layer underground saline water in the low plain around Bohai sea of Haihe River basin,a field experiment was conducted to investigate the effects of the different salinity water(0.72,2,3,4.3 g/L) irrigation on autumn Chinese cabbage yield and quality and soil salt accumulation in Hebei Linxi irrigation Experimental station in 2010 and 2011.The results showed that there were no significant difference among the effects of all the treatments on Chinese cabbage quality,and the effects among the treatments with 0.72,2,3 g/L on Chinese cabbage yield.The yields of the 4.3 g/L treatment were lower than that of 0.72 g/L,and the 2-year average yield decreases by 9%.The soil salt content increased with the increase of the mineral content of saline water.更多还原
