摘要
为了解养分和地面覆盖对澳洲坚果生长和产量的影响,采用L9（34）正交设计,对8年生澳洲坚果品种344和OC开展施肥和覆盖试验。结果表明,试验实施1 a时,品种344的平均地径、树高、冠幅、冠高的增长率分别为13.0%、9.2%、4.1%、6.1%,品种OC的平均地径、树高、冠幅、冠高的增长率分别为6.3%、4.8%、1.3%、4.5%,品种间差异极显著（P≈0.000〈0.01）。各处理组合中,品种344的单株鲜果产量为0.5~1.4 kg/株,单位面积鲜果产量为191.6~470.1 kg/hm2;品种OC的单株鲜果产量为1.6~9.7 kg/株,单位面积鲜果产量为535.1~3 235.3 kg/hm2;各处理组合间,仅品种OC的单株产量呈现极显著的差异（P≈0.000〈0.01）;同一品种的不同单株间,产量差异也较大。影响生长和产量的主导因子因品种不同而异,所以对于不同的澳洲坚果品种应研究相应的丰产栽培技术。
In order to understand effects of nutrients and mulching on growth and nut yield in M. integrifolia, using 8-year-old 344 and OC varieties in M. integrifolia as materials, fertilization and mulching experiments were carried out adopting the L9（34） orthogonal design. The results showed that the mean increment ratios of basal diameter, tree height, crown width and crown height of 344 variety were 13.0%, 9.2%, 4.1% and 6.1%, and those of OC variety were 6.3%, 4.8%, 1.3% and 4.5%, respectively, when the experiments had been implemented for one year. There were significant differences between varieties （P≈ 0.000 〈 0.01）. The fresh nut yield of 344 variety was 0.5-1.4 kg per plant, and the fresh nut yield per unit area was 191.6-470.1 kg/hm2, in the treatments. While the fresh nut yield of OC variety was 1.6- 9.7 kg per plant, and the fresh nut yield per unit area was 535.1-3 235.3 kg/hm2. The yields per plant of OC variety had extremely significant differences between the treatments （P ≈ 0.000 〈 0.01）. The nut yield had great differences between individual trees of one variety. The main factors of growth and nut yield were changed with different varieties, so the technique of high yield cultivation should be for specific variety ofM. integrifolia.
