(一)土壤水份对腐烂病斑扩展的影响试验开始年度:1957年目的:认为涂泥法有治疗效果的原因之一,可能与水份的影响有关,所以就这方面进行了探讨。试验方法:将红星的徒长枝(休眠枝)剪成10厘米长作为试材。供试枝的上部进行烧伤,接种含菌的琼脂,后在25℃湿室下保持一周,形成病斑。在病斑边缘划上记号,然后从包括病斑部的上端至6厘米处,埋于含水率不同的供试土壤中,保持25℃,一周后调查
(A) of the impact of soil moisture on the spread of decay lesion start of the experiment: 1957 Purpose: that one of the reasons the effect of mud coating method may be related to the impact of water, so in this regard were discussed. Test Method: The star’s long branches (dormant branches) cut into 10 cm long as the test material. The upper part of the test branches were burned, inoculated with bacteria-containing agar, after a week at 25 ℃ wet room to form a lesion. Marked at the edge of the lesion, and then from the top including the lesion to 6 cm, buried in test soil with different moisture content, maintained at 25 ℃, a week later to investigate
