    摘要:

    我国热带地区具有高温多雨、雨量分布不均匀且多暴雨的特点,容易引起水土流失,土壤有机质分解快,养分淋溶流失强烈,因此热带地区的红壤和砖红壤的有机质和速效养分含量都很低。热带经济林木和果园间种绿肥覆盖作物可以保持水土,增进地力,促使主作物速生高产[1,2],而建立牧草基地以发展畜牧业和种植绿肥是增加优质有机肥料来源的有效途径。这样才有可能增施大量有机肥料,不断提高土壤肥力,保证农林作物稳产高产。

    Abstract:

    Experiments on the plantation of tropical green manuring plants and pastures on three red soils of western Kwangtung Province during 1963-1964 give the following remarks:Tephrosia candida and Crotarlaria anagyroides could be planted in poor soils under a rather dry soil condition.Tithonia diversifolia gave high yield within a short growing period but successwe plantation of this plant was confined only to the fertile soils.Tephrosia vestita has been found very resistant against dry and infertile soil condition.It was the only plant which should grow on acid sandy soil of the hill land.Under good soil moisture condition Sesbania cannabina could stand on infertile soils with rapid growth.Pueraria phaseoloides and Calapogonium mucunoides showed wide adoptability in this region.They served as good cover plants under bad soil conditions.Pueraria phaseoloides,Centrosema pubescens,Desmodium ovalifolium,Mimosa invisavar inermis and Oldenlandia auriculavia grew better under a shady condition than any other plants introduced in the experiments.
