| 摘 要： | 以甘肃省秦安县兴国镇郑川村盐分胁迫果园土壤为研究对象,研究了集雨灌溉对果园土壤剖面盐分离子和果树生长的影响.结果表明:在淋洗前后全盐(P=0.001<0.01)和水溶性Na+(P=0.000<0.01)有极显著的差异,Cl~-(P=0.040<0.05)和水溶性Ca~(2+)(P=0.045<0.05)有显著的差异,而K~+、Mg~(2+)、HCO_3~-、CO_3~(2-)和SO_4~(2-)在淋洗前后差异不显著.通过果园土壤淋洗,能够明显改善树体的生长状况,叶缘焦枯的叶片逐渐恢复正常.

| Abstract: | The object of study was the orchard soil in Zhengchuan Village of Xingguo Town in Qin'an County of Gansu Province under salt stress,with which a field irrigation experiment using harvested rainwater was carried out to determine effects of irrigation with harvested rainwater on salt and ions content in orchard soil profile and apple tree growth.The results show that there was a very marked difference between before leaching and after leaching on soil total salt(P=0.001<0.01) and water-solubility sodium(P=0.0... |
