| 摘 要： | 8月中下旬芦笋茎枯病严重发生时,利用芦笋有不断发新茎的习性,采用换茎防病措施,使芦笋茎枯病得到较好的控制。至10月中下旬,防病效果可达84.9％～98％,重病田换茎,翌年产量可增加70.1％～124％,芦笋长势好,茎数增加64.6％,生长系数增加103.7％,且有明显的增产后效应,至第3年,换茎仍比对照增产26.9％～48％,中度病田和轻病田换茎芦笋产量与对照无差异。

| Abstract: | It was shown that the asparagus stem blight [Phomsis asparagi (Sacc. ) Bubak] could be controlled by using stem exchanging during mid and late August when the disease took place severely. The effect of control was up to 84. 9% - 98% in the second and the third ten days of October. The yield of asparagus with exchanged stem increased by 70. 1 % -124% in the seriously diseased fields the next year. The number of stems and growth coefficient increased by 64. 6% and 103. 7%, respectively. The yield in treated field was 24. 9%- 48% higher than that of untreated field after stem exchanging in severely diseased field until the third year but there was not difference between the treated and the untreated in moderately and lightly diseased fields. |
