通过修枝、间伐、改变栽植密度等手段对杨树人工林破腹病的发生规律进行了探索。发现修枝、间伐对杨树破腹病有加剧的作用,栽植行向对破腹病的发生影响较小,受阳光照射较强的西边和南边发病严重,栽植的密度适当增加,破腹病能够减轻。研究证明,光照与温度是破腹病发生的最关键因素。 Through the pruning, thinning, changing the planting density and other means of poplar plantation breaking the rule of belly disease were explored. It was found that pruning and thinning had an aggravating effect on poplar blight. The effect of planting line on the occurrence of broken belly disease was small. The incidence of severe radiation in the west and south was severe, and planting densities were increased appropriately. Can reduce. Studies have shown that light and temperature are the most critical factor in the occurrence of CBS.
