在毛主席“绿化祖国”的光辉思想指引下,我场营造了大面积红松人工林。目前幼树生长旺盛,长势喜人。如,1963年在草河口大平台子营造的150亩,平均保存率达88%以上,栽后9年,平均树高3.28米,平均地径7.5厘米。几年来,经过“实践、认识、再实践、再认识”初步总结出营造红松人工林的几项有效技术措施。一、林地选择与清理红松不苛求土壤肥力,在中等土壤条件下便可以生长发育,而在土壤较肥沃、湿润、排水良好的山地阴坡或半阴坡,特别是山的中下腹为最好。在表土层达20厘米左右的陡坡(25°-40°)小环境(山坳、山麓)及较好的阳坡也可栽植红松,并幼树生长良好。但是,红松对土壤水分条件要求较严格,不宜栽植在地势低洼排水不良及易遭受风害的冲风口地方。红松较喜光,全光条件生长最好,适宜全 Guided by the glorious idea of ​​Chairman Mao’s “greening the motherland,” I built a large area of ​​Korean pine plantation. The current vigorous growth of young trees, the growth of gratifying. For example, in 1963, 150 mu of grass was built in Dahetai of Caohekou, with an average preservation rate of over 88%. After planting for 9 years, the average tree height was 3.28 meters with an average diameter of 7.5 centimeters. In recent years, after “practice, cognition, re-practice and re-cognition”, several effective technical measures for establishing Pinus koraiensis plantation have been initially summarized. First, the selection and clearing of woodland Pinus koraiensis is not demanding soil fertility, growth and development under moderate soil conditions, and in the soil is more fertile, moist, well-drained mountain shady or semi-shady, especially in the mountain of the lower abdomen it is good. Pinus koraiensis can also be planted in small lands (col, foothills) and sunny slopes of up to about 20 centimeters in the topsoil and saplings grow well. However, the Korean pine requirements of soil moisture more stringent conditions should not be planted in low-lying low-lying poor drainage and weather-prone air outlets. Korean pine preferred light, the best growth in all-optical conditions, suitable for the whole
