【摘要】 探究不同施药方式（喷施多菌灵+甲基硫菌灵，地面撒施多菌灵、地面撒施甲基硫菌灵）和附加措施（增喷乙蒜素、增施植物保护膜、撒施生石灰、地面覆盖塑料薄膜）对澳洲坚果黑果病防控效果的影响。结果表明：各处理发病率和发病指数均显著低于对照，防治效果在27.59%～85.30%。不同施药方式中，喷施处理的黑果病发病率和发病指数最低，防治效果最好，达85.30%，显著高于撒施处理；附加措施各处理对防治效果均无显著提升，和正常喷施多菌灵+甲基硫菌灵相比，增喷乙蒜素、地面覆盖塑料薄膜会显著降低防治效果；种植区土壤磷元素（111.75 mg/kg）远高于澳洲坚果适宜种植范围（10～20 mg/kg），钙、镁、硼等元素缺乏。对澳洲坚果黑果病喷施多菌灵+甲基硫菌灵能获得较好的防治效果，无需附加其他防治措施，不同植区可根据地力情况合理施肥。更多还原

【Abstract】 Explore the effects of different pesticide application methods(spraying carbendazim+methyl thiophanate, ground spraying carbendazim, ground spraying methyl thiophanate) and additional measures(spraying allicin, applying plant protective film, spraying quicklime, covering plastic film on the ground) on the prevention and control of husk spot disease in macadamia. The results showed that the incidence rate and incidence index of each treatment were significantly lower than those of the control, and the control effect was 27.59%～85.30%. In different application methods, the incidence rate and incidence index of husk spot disease in spraying treatment were the lowest, and the control effect was the best, reaching85.30%, significantly higher than that in spraying treatment; The additional measures did not significantly improve the control effect of each treatment. Compared with normal spraying of carbendazim+methyl thiophanate, adding allicin and covering the ground with plastic film would significantly reduce the control effect; The phosphorus content in the soil of the planting area(111.75 mg/kg) is much higher than the suitable planting range for macadamia(10～20 mg/kg), and there is a lack of elements such as calcium, magnesium, and boron. In summary, spraying carbendazim and methylthiophanate methyl on the husk spot disease of macadamia can achieve good control effects without the need for additional control measures. Different planting areas can be fertilized reasonably according to soil fertility conditions.更多还原
