摘要
为了缓解水资源短缺,开发利用地下微咸水对宁夏银北盐碱地区枸杞进行不同灌水定额试验。结果表明:微咸水滴灌下,土壤含水量纵向60 cm土层内及水平方向随灌水定额的增大先减少后增加,60 cm土层下随之而减少;土壤含盐量纵向80 cm土层内随灌水定额的增大而减少,80 cm土层下随之而增加,水平方向先增加后减少,整体脱盐效果明显;枸杞生育期内长势良好,无死苗减产现象。综合各项因素,说明短期内利用微咸水滴灌枸杞是可行的,且灌水定额549 m3/hm2较为适宜。
In order to alleviate the shortage of water resources, different irrigation quota experiment on wolfberry in saline region of Ningxia Yinbei were carried out to develop and utilize underground brackish water. The results showed that under the condition of brackish water drip irrigation, the soil water content within 60 cm soil layer and under 60 cm soil layer increased, and decreased respectively along with the increasing of irrigation quota; The soil salt content within 80 cm soil layer and under 80 cm soil layer decreased and increased respectively along with the increasing of irrigation quota; The overall desalination effect in 80 cm soil layer was obviously. Wolfberry was growing well in the whole growth period and no seedling death phenome- non. Considering the above various factors, brackish water irrigation in short term wolfberry was feasible, and the irrigation quota of 549 m3/hm2 was more appropriate.
