为探讨钙肥对瘠薄红壤旱地花生土壤理化性质影响,同时为优化花生生长环境提供理论依据,本研究在湖南长沙选取红壤瘠薄旱地以及3个不同粒型大小花生品种(大粒湘花2008、中粒湘花55、小粒蓝山小籽),运用土柱试验栽培法,设置施钙肥(CaO)和不施钙2个处理,对花生主要生育期的根际、0~20cm土壤理化性质进行测试与分析。结果表明:在缺钙酸性土壤下,施钙能提高所有品种、各时期(成熟期略有不同)、各土层花生土壤的pH值,调节土壤过酸强度;提升土壤有机质含量(蓝山小籽>湘花2008>湘花55);显著增加土壤碱解氮含量(湘花55>湘花2008>蓝山小籽);更好地提高大、中粒型品种土壤有效钾含量;降低大、中粒型品种土壤...

In order to explore the effect of calcium fertilizer on physical and chemical properties of peanut soil in arid red soil and to provide theoretical basis for optimizing the growth environment of peanut, three peanut varieties of different grain sizes (large-grain Xianghua 2008, medium-grain Xianghua 55 and small-grain Lanshan small-grain) were selected in Changsha, Hunan Province, and cultivated by soil column experiment.In this study, the physical and chemical properties of rhizosphere and 0-20 cm soil in the main growth period of peanut were tested and analyzed by setting two treatments of c...
