为探索河北杨扦插育苗技术,我们进行了温床扦插育苗试验,其试验结果分述如下: 一、试验地环境试验地是无灌溉水源的旱地苗圃。海拔1,858米,地势平坦。土壤有机质含量少,钙质多,易板结。酸碱度8.0～8.5。年平均气温6.8℃,冬季寒冷干燥,以西北风为主,年平均降水量398.5毫米,年平均蒸发量1695.7毫米,相当降水量的4倍。二、试验材料和方法 1、种条采集。种条采集分冬季和春季两种。 To explore the Yang cuttage seedling technology in Hebei, we conducted a cutting seedling cutting test, the test results are described as follows: First, the experimental site for environmental testing is a non-irrigated dry land nursery. 1,858 meters above sea level, flat terrain. Soil organic matter content less, more calcium, easy to knot. PH 8.0 ~ 8.5. The annual average temperature of 6.8 ℃, cold and dry in winter, mainly to the northwest wind, the average annual rainfall of 398.5 mm, the average annual evaporation of 1695.7 mm, four times the amount of precipitation. Second, the test materials and methods 1, species collection. Seed collection points in winter and spring two.
