我场是一个地势高寒,沟壑纵横,干旱少雨的地方。海拔1900米,年平均气温6.9℃,最高34.1℃,最低-22.7℃。年平均降雨量426.8毫米,年平均蒸发量2115.2毫米。土壤平均含水率12.3％。为了达到侧柏上山造林的目的,我们进行了旱地育苗试验。经过多次失败,总结出:旱地育侧柏苗与复土厚度有很大关系。因此我们又开展了不同复土深度的育苗试验,取得成功。出苗率90％,生长良好,其具体作法如下。一、选种:把侧柏种籽倒入缸内,加入温水(50℃左右)搅拌,捞掉上浮秕籽,下剩好种籽泡两天后捞出来,混沙堆藏,勤翻动,经5～7天,种籽裂嘴露白,即可播种。
My field is a terrain, ravines, dry and rainy areas. 1900 meters above sea level, the annual average temperature of 6.9 ℃, the highest 34.1 ℃, the lowest -22.7 ℃. The average annual rainfall of 426.8 mm, the average annual evaporation of 2115.2 mm. The average soil moisture content 12.3%. In order to achieve the purpose of afforestation on Platycladus orientalis, we conducted a nursery experiment on dry land. After many failures, concluded: Upland nursery cypress seedlings and the thickness of the soil has a great relationship. Therefore, we carried out nurturing experiments with different soil depths and achieved success. Emergence rate of 90%, good growth, its specific practices are as follows. First, the choice of species: Platycladus seeds into the cylinder, add warm water (50 ℃ or so) mixing, fishing float floating seeds, the remaining good seeds after two days to remove the fish bubble, sand mixed storage, ground flip, After 5 to 7 days, the mouth cracking mouth white, you can sow.
