激光是六十年代发展起来的一门新兴科学技术。它是电子学与光学相结合的产物,具有方向性好、亮度高、颜色纯、功率大等一系列优良特性。几年来在工业、农业、国防以及医疗卫生等部门得到了广泛应用,并显示出巨大地威力。为了探索激光在林业育苗中的应用,我们于1978年开始对樟子松育苗作了尝试,试验是在长春市东风苗圃进行的。播种前将樟子松种子作了激光不同照射剂量的处理,播种后经过两年的观察,不同照射剂量对樟子松苗木生长产生了显著的差异。现将试验
Laser is an emerging science and technology developed in the 1960s. It is a combination of electronics and optics, with good direction, high brightness, pure color, high power and a series of excellent features. Over the past few years in the industrial, agricultural, national defense and medical and other departments have been widely used, and showed great power. In order to explore the application of laser in seedling raising in forestry, we started to try to cultivate Pinus sylvestris var. Mongolica in 1978. The experiment was carried out in Dongfeng nursery of Changchun. Seedlings of Pinus sylvestris var. Mongolica were treated with different laser doses before sowing. After two years of sowing, seedlings of Pinus sylvestris var. Mongolica were significantly different in different irradiation doses. Now test
