为了探索北京杨在康定姑咱地区扦插育苗技术。1983年,在我校开设的实习苗圃中,进行了扦插育苗试验。 试验地的自然条件 位于北纬29°58′,东径102°10′,大渡河流经此地。本区气候由于受西风环流和焚风增温效应影响,属于干旱河谷气候类型,海拔高1400米左右。气候夏凉冬暖,年平均气温15—17℃,最热月平均23—35℃,最冷月平均为3—8℃。无霜期250天以上。大于10℃以上积温4700℃左右,干燥度为1.1—1.5,年降雨500—600毫米,多集中于5—9月。
In order to explore the Beijing Yang Kanggugan we cuttings nursery area technology. In 1983, in our school opened internship nursery, carried out cuttage nursery test. The natural conditions of the experimental site are located at 29 ° 58 ’north latitude and 102 ° east 10’ where the Dadu River flows through here. The climate in this area is affected by the westerly circulation and the warming effect of burning winds and belongs to the arid valley climate type with an altitude of about 1400 meters. The climate is cool in summer and cool in winter with an annual average temperature of 15-17 ° C. The hottest month average is 23-35 ° C and the coldest month is 3-8 ° C on average. Frost-free period of 250 days or more. More than 10 ℃ above the accumulated temperature of 4700 ℃, the dryness of 1.1-1.5, annual rainfall of 500-600 mm, mostly concentrated in May-September.
