摘　　要：近年在我国罗汉果主产区严重发生罗汉果芽枯病。通过植物寄生生物学、土壤学及植物营养学分析 ,证明该病为缺硼所致的生理性病害。土壤酸化是导致其有效硼含量减少的重要原因。大田试验结果表明 ,深施硼砂加石灰对控制该病发生、促进罗汉果植株生长、提高植株含硼量及其产量具有很好的效果。In recent years, a bud blight of Siraitia grosvenori was seriously occurred in the main producing district of the crop in China. It has been proved that the disease is a physiological disorder caused by boron deficiency based on the phytoparasitological, pedological and phytonutriological analyses.It was confirmed that in the past eighteen years, severe soil acidification resulted in the loss of boron in the soil. It is effective for controlling the disease by applying a mixture of borax and lime into the soil around S. grosvenori plants. The content of boron in the plants and the fruit yields can be significantly raised by applying boron fertilizer.
