我组于1979年12月21日开始进行了控制侧芽促进油杉苗木生长的试验。试验场地设置本所苗圃。试验前,将待试苗木的高度逐一进行了测量,以作评定试验效果的基数。试验过程中,除试验因子水平外,环境因子和其他管理措施等均趋于一致(其目的在于力求减少试验的外来误差)。截至7月10日,共进行了两次去芽和两次测量。第一次每株平均去芽10个,第二次每株平均去芽6 My group in December 21, 1979 began to control the side buds promote the growth of oil fir seedlings test. Test site set by the nursery. Before the test, the height of the seedlings to be tested was measured one by one to determine the base of the test effect. During the test, except for the level of experimental factors, the environmental factors and other management measures tend to be consistent (with the purpose of reducing the experimental external error). As of July 10, a total of two budding and two measurements were performed. The average number of shoots per plant is 10, and the average number of shoots per plant is 6
