三峡库区紫色土旱坡地农桑配置模式对土壤养分的影响OA北大核心CSCDCSTPCD
Effects of different crop-mulberry intercropping systems on nutrients in arid purple soils in the Three Gorges Reservoir Area
针对三峡库区紫色土流失严重和土壤肥力低的现状，本试验利用水土保育模式———农桑间作试验，研究横坡农作（CT）、双边桑树＋横坡农作（T1）、等高桑树＋双边桑树＋横坡农作（T2）及四边桑树＋等高桑树＋横坡农作（T3）4个处理对土壤养分的影响。结果表明，桑树布局小区内的土壤碱解氮、速效磷、速效钾和有机质含量均有极显著提高，且土壤碱解氮、速效磷、速效钾和有机质含量平均值大小均表现为：等高桑树＋双边桑树＋横坡农作（T2）＞四边桑树＋等高桑树＋横坡农作（T3…查看全部>>
To help address the problem of purple soil erosion on sloping land in Chongqing city,an experiment has been undertaken to investigate the effects of different crop-mulberry intercropping systems on soil nutri-ents.Four treatments were designed:crops were planted along transverse slopes (CT),crops were planted a-long transverse slopes with mulberry trees on the upper and lower slopes (T1 ),crops were planted along trans-verse slopes with mulberry trees on the…查看全部>>
