旱地多熟间套作不同培肥方法对作物产量和土壤肥力的影响

Effect of crop yield and soil fertility on different fertilization methods in dry farmland multpliate seasons and relay intercropping

通过设三季秸秆还田、三季秸秆+冬绿肥还田、三季栏肥还田、冬绿肥还田及主施化肥为对照等5个处理,研究了山区旱地多熟间套作不同培肥方法的培肥效果,试验结果表明,各种培肥方法的培肥效果依次为三季栏肥还田>三季秸秆+冬绿肥还田>三季秸秆还田>冬绿肥还田>对照。

Effect of fertilization on different fertilization methods in mountain area dry farmland was researched. The methods were three seasons cane, three seasons cane ＋ winter green manure crop, three seasons fodder fertilizer, winter green manure crop and check. It provided scientific basis for upgrading dry farmlang soil properly and fertility. It was suggested that fertilization effect in proper order ： three seasons fodder fertilizer 〉 three seasons cane 〉 three season cane ＋ winter green manure crop 〉 three seasons cane manure 〉 winter green manure crop 〉 cheek.
