| 摘 要： | 通过盐碱性防护林地播种大麦的试验,结果表明:夏季高温干旱"返盐碱"期间,防护林地播种大麦,其土表(0～20cm)层可溶性盐分和pH值分别比未实施播种大麦的平均降低0.9 g·kg-1和0.4;有机质、水解氮、有效磷和速效钾的平均含量分别比未实施播种大麦的增加5.4 g·kg-1、106.6 mg·kg-1、15.1 m...

| Abstract: | Through experiments of sowing barley on saline-alkali shelter-forest soil,result shows that during "return saline-alkali" period in summer with high temperature & drought,soluble salt & pH value in the soil surface(0-20 cm) layer on shelter-forest soil planted with barley are average 0.9 g·kg-1 & 0.4 lower respectively than that on shelter-forest soil planted without barley;average contents of organic matter,hydrolysis nitrogen,available phosphorus & available potassium are respectively 5.4 g·kg-1,106.6 mg·kg-1,15.1 mg·kg-1 & 77.3 mg·kg-1 higher than that in the soil of shelter-forest planted without barley;soil doesn’t appear " return saline-alkali "(white) phenomenon;this method can effectively prevent " return saline-alkali "of shelter-forest afforested on saline-alkali soil in high temperature & drought season and improve forest soil conditions;it should be popularized in actual work. |
