巴梨产量高,品质好,甚受市场欢迎。但易感染干腐病,造成树势衰弱,生长不良,影响梨的产量和质量。我县前曹乡张茂吴村1976年春栽植巴梨168株,1981年有3株发生干腐病,1933年已发展到16株。1984年我们对其中11株树进行了防治(下余5株病树不防治为对照),取得良好效果。 Pakistani pear high yield, good quality, very welcomed by the market. However, susceptible to dry rot, resulting in weak bark, poor growth, affecting pear yield and quality. 168 villages were planted in the spring of 1976 in Zhangmao Wu Village, Cao County before my county. Three dry rot occurred in 1981 and 16 in 1933. In 1984, 11 of our trees were under control (the remaining 5 diseased trees were not controlled), with good results.
