为了提高池杉种子育苗的出圃率,近两年来,我们在本县黎城乡响墩六组进行了池杉小苗移栽,现将具体做法介绍如下:一、整地在冬季进行苗圃地的耕翻冻垡和用0.5%福尔马林的土壤消毒工作,开春后下足腐熟的基肥,以提高土壤肥力.二、种子处理从1月下旬开始,每天将种子用70℃的热水进行浸泡,晚上捞出,这样连续浸泡20天.同时,选背风向阳的地方挖长2米、宽1米的地窖.窖内底部铺20厘米厚的棉籽壳或牛粪,上面铺以细土,然后把浸泡过的种子平摊在土上,喷足40℃的温水,盖上塑料薄膜催芽(晚上盖草帘保温).膜内要保持湿润,温度一般在20—25℃.经15天后,窖内池杉种子即陆续发芽. In order to improve the seedling nursery seed pool rate, in the past two years, we have in the county Li Xiang Xiang pier six groups of transplanting seedlings of spruce, the specific practices are as follows: First, the preparation of land in winter nursery tilling Frozen 垡 and 0.5% formalin soil disinfection work, after the spring under foot maturity basal fertilizer, in order to improve soil fertility. Second, the seed treatment from the beginning of late January, the seeds were soaked with hot water at 70 ℃, At the same time, digging 2 meters long and 1 meter wide cellar in the leeward sunny place, the bottom of the cellar is covered with 20 cm thick cottonseed shell or cow dung, covered with fine soil, and then put Soaked seeds spread evenly on the soil, sprayed enough warm water 40 ℃, covered with plastic film germination (cover straw curtain insulation at night.) To keep the membrane moist, the temperature is generally 20-25 ° C. After 15 days, the cellar Ipomoea seeds that one after another germination.
