在毛主席无产阶级革命路线指引下,为摸索高原山区飞机治虫的经验,我们应用运五型飞机于1966年和1969年2-4月间,在云南的思茅、保山进行了大面积航空化学治虫试验,收到了一定效果。现将实验情况和结果整理于后,供生产中参考。一、基本情况(一)试验区:思茅、保山两个试验区是天然次生林,总面积为18万余亩,海拔高在1,500米以上,山岭起伏,地形较复杂,思茅为近熟林,保山为中幼林,郁闭度为0.4-0.7。
Under the guidance of Chairman Mao’s proletarian revolutionary line and in order to explore the experience of pest control in plateau mountainous areas, we conducted a large-scale aeronetalization and pest control of the aircraft in Simao and Baoshan in Yunnan Province between 1966 and February-April 1969, Test, received a certain effect. Now the experimental conditions and results sorted in for production reference. First, the basic situation (A) pilot area: Simao, Baoshan two pilot area is a natural secondary forest, with a total area of 180,000 acres, the elevation of 1,500 meters above the mountain ups and downs, the topography is more complex, Simao near-mature forest, Baoshan For young trees, canopy density 0.4-0.7.
