| 为了解澳洲坚果在贵州的产量表现，以引进的4个澳洲坚果品种为试材，研究初产期不同树龄与产量的表现。结果表明：随着树龄的增长，4个品种的总产量呈快速增长，三年累计总产量表现为O.C＞H2＞HAES 788＞HAES 344，O.C在不同树龄阶段总产量均高于其他品种；平均单株产量品种O.C显著高于其它3个品种，H2在第9年单株产量出现较大增长，HAES 344始终最低；O.C的总产量和平均单株产量的增长率均为最低，H2平均单株产量的增长率最高，且在第9年总产量和平均单株产量的增长量均最高；4个品种单株产量的平均变异度O.C的最小，其次为HAES 788、H2和HAES 344；随树龄增长，O.C低增长（小于50%）的单株比例增加，H2高增长（大于等于200%）的单株比例增加；HAES 788中增长（大于等于50%小于200%）的比例增多，HAES 344低增长的比例增多。在贵州望谟生态条件下，品种O.C在不同树龄阶段总产量、单株产量、稳定性表现均优于其它三个品种。 |

| In order to understand the yield performance of Macadamia in Guizhou, four introduced Macadamia varieties were used as test materials to study the yield performance of different tree ages in the initial production period. The results showed that: the total yield of the four varieties increased rapidly with the growth of tree age. The cumulative total yield was O.C>H2>HAES 788>HAES 344 in three years. The total yield of O.C was higher than that of other varieties at different tree age stages; The average yield per plant of O.C was significantly higher than that of the other three varieties. The yield per plant of H2 increased greatly in the ninth year, and HAES 344 was always the lowest; The growth rates of total yield and average yield per plant of O.C were the lowest; The growth rate of average yield per plant of H2 was the highest, and the growth rates of total yield and average yield per plant were the highest in the ninth year; Among 4 varieties, O.C possessed the lowest coefficient of variance of yield per plant, followed by HAES 788, H2 and HAES 344; With the growth of tree age, the proportion of single plant with low growth (less than 50%) of O.C and high growth (greater than or equal to 200%) of H2 increased; The proportion of single plant growth (greater than or equal to 50% and less than 200%) of HAES 788 and low growth of HAES 344 increased. Under the ecological conditions of Wangmo, Guizhou Province, the total yield, yield per plant and stability of O.C were better than those of the other three varieties at different tree ages. |
