2010年7月对新疆库车县杏树流胶病发病情况进行了调查。结果表明,被调查杏园的田间平均发病率为95.6%,最高100%;平均病情指数为58.9,最高85.0。流胶主要有皮孔流胶和伤口流胶两大类型,其中伤口流胶又可分为机械损伤、虫口、树皮裂缝等情况,其所占比例因果园的具体情况不同而异。一般当年新出胶液随时间的延长颜色逐渐加深变褐色,由虫口流出的胶液初为透亮淡黄色最后变为白色。胶体质地逐渐变硬并出现龟裂,遇雨后变软;解剖流胶病斑组织,可见发病部位有不同程度的褐变腐烂,胶液由韧皮部和木质部间的形成层流出。
July 2010 in Kuqa County, Xinjiang almond tree gum disease incidence survey. The results showed that the average incidence of field apricot fields surveyed was 95.6%, the highest 100%; the average disease index was 58.9, the highest 85.0. There are two main types of plastic: leather plastic and plastic wound glue. The wound plastic can be divided into mechanical damage, insect mouth and bark cracks. The specific proportion of the causal garden is different. The general new year glue out of color over time to deepen the brown color gradually, from the mouth of the glue out of the initial pale yellow translucent finally turned white. Colloid texture becomes harder and cracked, softening in case of rain; dissection flow gum plaque tissue, showing the incidence of browning decay to varying degrees, glue from phloem and xylem formation layer out.
