黑荆树引种我区以来,经观察发现有的有花不孕,个体性状变异不大,优良个体数量较少。为解决良种繁殖问题,于1984年5月—1985年7月采用正交设计L_9(3~4),进行扦插育苗试验,共扦插13080株。现将试验结果报告于后: 一、试验地概况:试验地在海拔570米半阳坡,中部,坡度12度,年降雨量1193毫米,最大月降水量186毫米,7月份,6月份降水量154毫米。年平均气温17.3℃,6月份平均气温25℃,年极端最高气温39.5℃,最低气温-1.3℃。年平均地面温度18.8℃,6月份平均地面温度27.5℃,6月份最高地面温度40.2℃,年平均湿度79％,6月份平均湿度78％。
Introduction of black wattle since my area, the observation found that some flowers infertility, individual traits variation is small, the number of fine individuals less. In order to solve the problem of seed multiplication, in the May 1984-July 1985 orthogonal design L_9 (3-4), cutting propagation test, a total of 13080 cuttings. Now the test results are reported later: First, the test site profile: The test site at 570 meters above sea level on the Mid-Yang slope, the central slope of 12 degrees, the annual rainfall of 1193 mm, the maximum monthly precipitation of 186 mm, July, June precipitation 154 mm. The annual average temperature of 17.3 ℃, June average temperature of 25 ℃, annual extreme maximum temperature of 39.5 ℃, minimum temperature of -1.3 ℃. The average annual surface temperature of 18.8 ℃, the average ground temperature in June 27.5 ℃, the highest ground temperature in June 40.2 ℃, annual average humidity of 79%, the average humidity in June 78%.
