蜀桧是圆柏属的一个栽培变种,主干通直,枝叶茂盛,色泽翠绿,结构紧密,树冠呈圆锥(柱)形,生长迅速,耐修剪,结合整形能修剪成多种姿态,是优良的园林绿化树种之一。由于他的适应性较强,目前也成为向北推进的优势树种。我们针对蜀桧母树少,且生产中多采用大穗扦插,繁殖系数低,所育苗木不能满足社会需要的情况,于1984年进行了大、中、小穗扦插育苗试验。从生长旺盛、无病虫害的3—5年生植株上剪取穗条,分别剪成大(约15厘米)、中(约10厘米)、小(约5厘米)三级插穗,每100株一捆。在500ppm
Shu juniper is a cultivated varieties of Juniper, trunk straight, lush foliage, green color, compact structure, the crown was conical (column) shape, rapid growth, resistance to pruning, combined with shaping can be trimmed into a variety of postures, is excellent Landscaping tree species. Due to his strong adaptability, it is also the dominant tree species to advance northward. We aimed at Shu cypress tree less, and the production of large-spike cuttings, breeding coefficient is low, the seedlings can not meet the needs of the community, in 1984, large, medium and small spike cutting seedling test. The cuttings were cut from 3 to 5 year-old plants with vigorous growth and no pests and diseases and were cut into large (about 15 cm), medium (about 10 cm) and small (about 5 cm) cuttings, .
