摘要
通过正交试验设计研究光皮桦采穗母株不同定植株行距、不同截干高度和施用不同种类的基肥对母株产穗量的影响;研究了光皮桦不同种源家系对母株产穗量的影响。结果表明,母株定植株行距A3(30 cm×30 cm)+母株截干高度B3(距根茎部位40 cm处)+施用基肥C2(1 050 kg.hm-2硫酸钾复合肥)组合A3B3C2产穗量最高;光皮桦7个不同种源家系最优单株中,以Zx30及Zx18家系产穗量最高。
The effect of different planting densities of scion pluching nursery, different height of truncation and different kinds of fertilizers were studied in this paper as different provenance families affecting on scion yield. The results showed that the quantity of pluching scion was the largest with the combination A3B3C4, i.e. density of 30 cm× 30 cm, truncation height of 40 cm and compound fertilizer 70 kg per mu （ ≈ 666.7 m^2 ）. Family Z×30 and Z×18 had the largest quantity of plucking scion among 7 provenances of Betula lumini fera .
