建国以来,我区棕片平均年产量达2,000担左右,最高年份达3,013.8担(1981年)。但近年来,由于棕榈干腐病的为害,1984年仅产1,467担,严重威胁着棕榈生产的发展。为控制该病的发生与蔓延,提高棕片的产量和质量,我们于1985—1986年开展了棕榈干腐病的研究。一、材料与方法试材取自汝城县林科所棕榈病株。1.病原菌的分离与鉴定(1)诱发取寄主各部位的新鲜病组织,用自来水冲洗干净,再用无菌水冲洗三次,转入保湿培养皿中,置于26—28℃恒温培养篇内,经24小时后检查。
Since the founding of the People’s Republic of China, the average annual output of brown chips in our region has reached around 2,000 and the highest is 3,013.8 (1981). However, in recent years, due to the damage caused by the dry palm rot, it only produced 1,467 burries in 1984, which seriously threatened the development of palm production. In order to control the occurrence and spread of the disease and improve the yield and quality of the brown chip, we conducted a study on dry rot of palm in 1985-1986. First, the material and method Specimens from Rucheng County Forestry Branch palm disease. 1. Isolation and identification of pathogens (1) induced by the host take fresh parts of the disease tissue, rinse with tap water, and then rinsed with sterile water three times, transferred to the moist petri dish, placed in 26-28 ℃ incubator After 24 hours after the inspection.
