通过正交试验设计研究母株不同定植株行距、不同截干高度及施用不同基肥种类对马占相思嫩枝及硬枝产穗量的影响差异。结果表明:母株以20cm×25cm定植株行距(A2)+施1 125kg/hm2硫酸钾复合肥(B2)+母株距根茎部位25cm处截干高度(C3)组合(A2B2C3)最好,对嫩枝及硬枝产穗量均最高。
The effects of different planting line spacing, different height of cuttings and different basal fertilizer application on the yield of twig and hardwood branches of Acacia mangium were studied by orthogonal design. The results showed that A2B2C3 was the best when the parent plant was arranged at a spacing of 20cm × 25cm (A2) plus 1 125kg / hm2 potassium sulfate compound fertilizer (B2) + mother plant at the height of 25cm from the rhizome. Branches and hard branches yield the highest volume.
