微量元素是植物所需的营养成份之一,它是植物体内许多酶的组成部份,对植物的生理生化反应有多种催化作用,因而与生长密切相关。为了探讨微量元素对杉木生长的影响,从1981—1984年我们进行了浸种和喷施试验,取得了一定的效果。现将结果报道如下: 一、材料与方法 供试微量元素是钼酸铵、硼酸、硫酸铜、硫酸锌,硫酸锰等,对照为二次蒸馏水。试验用种分别为本省句容,江西全南、铜鼓,湖南江华种源。试前种子经筛选,剔除涩粒、瘪籽和杂质。 (一)浸种处理 种子浸种24小时后, Trace elements are one of the nutrients needed by plants. They are part of many enzymes in plants. They have a variety of catalytic effects on the physiological and biochemical reactions of plants and are closely related to their growth. In order to investigate the effect of trace elements on the growth of Chinese fir, we conducted soaking and spraying experiments from 1981 to 1984 and achieved some results. The results are reported as follows: First, the materials and methods for the test trace elements are ammonium molybdate, boric acid, copper sulfate, zinc sulfate, manganese sulfate, the control for the second distilled water. Test species were Jurong Province, Jiangxi Quannan, Tonggu, Hunan Jianghua provenance. Pre-test the seeds were screened, excluding astringent tablets, shriveled seeds and impurities. (A) seed soaking Seed soaking for 24 hours,
