摘　　要：采用完全随机设计,对品种294、H2、900进行了保花保果措施对产量及品质影响的试验研究,结果表明:不同品种的产量及品质差异均达极显著水平(F>F0.01),品种900、294的产量极显著高于品种H2,其平均产量分别为7.45kg/株、6.48kg/株,而品种H2的平均产量为2.09kg/株。品种294的一级果仁率极显著高于品种H2、900,其一级果仁率平均为91%,品种H2为75%,品种900为74%。保花保果措施对产量的影响差异达极显著水平(F>F0.01),盛花期喷施5000mg/L的硼砂溶液和5000mg/L尿素+5000mg/L磷酸二氢钾的混合溶液,3个品种的产量均高于对照,品种294分别提高152.69%和88.79%;品种H2分别提高1049.43%和88.79%;品种900分别提高130.78%和109.45%。保花保果措施对品质的影响不大且差异不显著(F<F0.05)。盛花期喷施5000mg/L的硼砂和5000mg/L尿素+5000mg/L磷酸二氢钾的混合溶液,3个品种的产量及一级果仁率,相对于其它措施都较高。By absolute randomized design,used 294、H2、900 as material to study the effect of measures of protecting flowers and fruits on the yield and quality of Maeadamia, the results showed that： The difference of yield and quality between different varieties all arrived to best marketable level（F〉F0.01 ）,the average yield of variety 900、294 were 7. 45kg/individual plant,6. 48kg/individual plant separately which best highest than variety H2,the average yield of variety H2 was 2.09kg/ individual plant. The first level nutlet rate of variety 294 was 91% which best highest than variety H2、900,variety H2 was 75%,variety 900 was 74% . The difference that the effect of the measures of protecting flowers and fruits on the yield arrived to best marketable level（F〉F0.01 ）,with borax（5 000 mg/L）,Garbamide（5 000 mg/L）＋ Monopotassium phosphate（5 000 mg/L） during flourish florescence,yield of three varieties all higher than comparison, variety 294 enhanced 152. 69%, 88. 79% separately; variety H2y enhanced 1049. 43%, 88. 79% separatel; variety 900 enhanced 130. 78%,109.45%separatelyo The difference that the effect of the measures of protecting flowers and fruits on the quality not arrived to marketable level（F〈F0.05 ）. With borax（5 000 mg/L）,Carbamide（5 000 mg/L）＋ Monopotassium phosphate（5 000 mg/L） during flourish florescence,the yield and quality of three varieties all higher than other measures of protecting flowers and fruits.
