摘要
通过正交试验设计研究直杆大叶相思良种采穗圃母株不同定植密度、不同截干高度及施用不同种类的基肥对母株产穗量的影响,结果表明:直杆大叶相思母株定植株行距20 cm×20 cm,配合母株距根茎部位20 cm处截干,结合每667 m2施用70 kg硫酸钾复合肥作基肥(A3B3C2)组合产穗量最高。
Through the design of orthogonal test, the effect of different planting density and stump height and fertilizer of maternal plant of Acacia auriculi in cutting orchard on scion yield was studied. The results show that the largest quantity of scions of Acacia auriculi is obtained with the basal fertilizer （A3B3C2） by the combination of the interplant space of 20 cm × 20 cm,the cutting height of 20 cm and fertilization of 70 kg compounding fertilizer of potassium sulfate per 667 m^2.
