摘要
辣木(Moringa oleifera Lam)两个种源。为确定株距和刈割间隔期对饲料生产中叶片生物量产量的影响，对马拉维和Mutoko三个品种进行了评价。采用以种源为主样地因子，株距为次样地因子，刈割间隔为次样地因子的分畦试验设计。以15 cm × 15 cm和20 cm × 20 cm两个株距，60 d和75 d两个扦插间隔进行试验。结果表明:种植90 d后，在20 cm × 20 cm间距下，马拉维种源植株叶片干物质产量显著高于Mutoko植株(P < 0.05);2个种源扦插间隔60 d的叶片干物质产量均高于扦插间隔75 d (P < 0.05)。这两个种源都可以推荐用于农林业，因为它们的叶片生物量产量在随后的60和75天的采伐间隔内没有显著差异。
The Effect of Provenance, Plant Spacing and Cutting Interval on Leaf Biomass Yield of Moringa Oleifera Lam.
ABSTRACT Two provenances of Moringa oleifera Lam., Malawi and Mutoko, were evaluated to determine the effect of plant spacing and cutting interval on the leaf biomass yield for fodder production. A split-split plot experimental design was set up with provenance as the main plot factor, plant spacing as sub-plot factor and cutting interval as sub-sub plot factor. The provenances were tested at two plant spacings of 15 cm × 15 cm and 20 cm × 20 cm, and two cutting intervals of 60 days and 75 days. Results showed that 90 days after planting, at 20 cm × 20 cm spacing, Malawi provenance plants had a higher (P < 0.05) leaf dry matter yield than Mutoko plants. A cutting interval of 60 days had a higher (P < 0.05) leaf dry matter yield for the two provenances than a 75 day cutting interval. Both provenances can be recommended for agroforestry because their leaf biomass yields were not significantly different at all subsequent cutting intervals of 60 and 75 days.
