南坪林区干海子科研站,1983、1984年,试验用三十烷醇浸云杉种子,浸苗,根和苗期喷施试验,两年结果如下: 一、三十烷醇促进云杉苗期生长。苗圃内设面积1.2—2米~2试验方块6个,对照1个。供试苗木为3年生粗枝云杉。在苗木生长旺盛期用0.01、0.05、0.1、0.5、1、5PPM浓度的三十烷醇喷施苗木新茎叶。用量2.5斤/米~2。施用时间,6月2日、6月23日两次,晴天下午4点以后喷施。田间管理和大面积生产苗圃相同。采用机械抽样,每方块取两行苗木测定。
In 1983 and 1984, the experimental dry spraying test of triacontanol with spruce seeds, soaking seedlings, roots and seedlings was carried out in Nanping Forest District. The results for two years were as follows: 1. Triacontanol promoted spruce Seedling growth. The nursery has an area of 1.2-2 m ~ 2 test squares 6, a control. The test seedlings are 3-year-old rough branches spruce. Seedlings in the vigorous growth of seedlings with 0.01,0.05,0.1,0.5,1,5 PPM triacontanol spray seedlings new stems and leaves. The amount of 2.5 kg / m ~ 2. Application time, June 2, June 23 twice, sunny afternoon after 4 pm spraying. Field management is the same as large-scale nursery production. Using mechanical sampling, take two rows of seedlings per square.
