石梓,又名滇石梓,是热带地区的一种优良速生用材树种。材质优良,是高级家具、室内装饰、造船、胶合板以及造纸的优良用材。石梓在我国云南省有天然分布。目前我省栽培的,多为1961年从马来亚引种的,生长发育良好,但是母树不多,种子缺乏。为了解决繁殖问题,于1978年春作了两次扦插试验,现小结如下。一、试验情况扦插日期,一次是1978年2月25日,另一次是同年3月30日。取半年生实生苗和3年生树的枝条作插穗,随剪随插。分别将插穗下端2厘米在100ppm、200ppm萘乙酸中浸泡24小时。圃地用六六六粉消毒,一周后垫上黄泥心土和火烧泥或河沙约15厘米,并用较细喷头 Shi Zi, also known as Dian Shi Zi, is an excellent tropical species of timber species. Excellent material, high-grade furniture, interior decoration, shipbuilding, plywood and paper excellent materials. Shi Zi in Yunnan Province, China has a natural distribution. Currently cultivated in our province, mostly introduced from Malaya in 1961, good growth and development, but not many mother trees, lack of seeds. In order to solve the breeding problem, we made two cutting experiments in the spring of 1978 and summarized the following. First, the test situation Cutting date, once in February 25, 1978, another in the same year on March 30. Take semi-annual seedlings and 3-year-old tree branches for cuttings, with the cuttings inserted. The lower end of the cuttings were 2 cm in 100ppm, 200ppm naphthalene acetic acid soak for 24 hours. Nursery with six six six powder disinfection, a week after padded clay and fire clay or river sand about 15 cm, and with a smaller nozzle
