用二氧化硅砂土和氧化土进行几个盐浓度的试验,通过用灌溉稀释的海水,测定 Keauhou 品种澳洲坚果幼苗对盐浓度的忍受力,以植株高度的增长和营养成分来衡量植株对盐浓度的反应。在另外的试验中,供试土壤是取自澳洲坚果生长地区,其矿物学和化学性质不同的5个土壤,用稀释的海水使土壤盐碱化,然后用自来水滤洗脱盐,研究土壤的变化和植物的化学成分。结果是澳洲坚果幼苗对土壤盐含量中等 Several salt concentrations were tested with silica sand and oxide soils, and the endurance of salt concentration of Keauhou macadamia seedlings was determined by diluting seawater with irrigation. The plant height and nutrient content were used to measure the salt concentration Reaction. In a separate experiment, the test soils were five soils with different mineralogical and chemical properties from the macadamia growing area. The soils were salinized with dilute seawater and then tap washed with tap water to study soil Changes and the chemical composition of plants. The result is that macadamia seedlings have medium salt content in the soil
