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, the main producing areas in China Luo Han Guo germinating Luo Han fruit germ. Through plant parasitology, soil science and plant nutrition analysis, the disease is proved to be due to boron deficiency physiological diseases. Soil acidification is an important reason for the decrease of effective boron content. Field test results show that the deep application of borax plus lime to control the occurrence of the disease, to promote the growth of Luo Han Guo plants and improve plant boron content and yield has a good effect.
