我场于1982年对湿地松、火炬松进行了三种不同育苗方法的对比试验。现将试验结果介绍如下: 一、试验材料和方法供试种子经沙藏催芽一个半月后,用0.1％的新洁而灭溶液消毒20分钟,再继续沙藏催芽至播种前。 (一)芽苗移栽育苗 1.作床:选择有排灌条件、背风向阳处作温床。规格为:床宽1.2米,床长一般不超过10米(视种子多少而定),北高(50厘米)、南低(30厘米),东西两边倾斜。床砌好后在床内侧四周用0.1％的新洁而灭溶液消毒,然
My field in 1982 on the pine, loblolly pine three different methods of seedling comparison test. Now the test results are as follows: First, the test materials and methods for the test seed germination by the sand reservoir after a month and a half, disinfected with 0.1% of the new Jie and the solution disinfection 20 minutes, and then continued to promote sand storage until sowing. (A) shoot seedling transplanting seedling 1 for the bed: choose to have irrigation and drainage conditions, the leeward sunny place for the hotbed. Specifications: bed width of 1.2 meters, bed length is generally not more than 10 meters (depending on the number of seeds), north high (50 cm), south low (30 cm), both east and west tilt. After the bed is built around the bed with 0.1% of the new Jie and eliminate the solution disinfection, however
