造林六項基本措施的全面貫彻,是保証幼林成活高、生长好、实現林木速生丰产的根本关鍵。翁牛特旗高家梁国营林場,为了摸索林木生长的规律,进一步掌握实現林木速生丰产的有效措施。該場1959年春季营造了大面积楊树速生丰产林500多亩,分別采取了四种不同經营方法进行对比試驗,經过一年多的生长,已很明显的得出四种不同的結果。現将作法和所得成果分述于下,供各地参考。这里,是山区丘陵地带,海拔高1000米左右,年降雨量約300多毫米,蒸发量为2,194毫米,无霜期約4个月。土質为
The full implementation of the six basic measures for afforestation is the fundamental key to ensuring that young forests survive, grow well and achieve fast and productive forest trees. Wengniute flag Gaojialiang state forest farm, in order to explore the law of tree growth, and further grasp the effective measures to achieve fast growing forest yield. The spring of 1959 to create a large area of 500 acres of fast-growing high-yield poplar, respectively, taken four different operating methods for comparative testing, after more than a year of growth, it has been very clear to draw four different results. Now the practice and the results obtained are summarized below for reference. Here is a mountainous hilly area, about 1000 meters above sea level, the annual rainfall of about 300 mm, the evaporation of 2,194 mm, frost-free period of about 4 months. Soil is
