浮山县苗圃于1985年春进行毛白杨斜栽埋杆育苗试验,1986年在总结试验的基础上,又用此法繁殖毛白杨苗木32亩,取得了良好的效果,平均亩产苗4100株,平均苗高1.5米,地径1.2厘米,苗木长势较好。方法是:1、母株的选取:选生长健壮、芽子饱满、根系发育好、无病虫害、木质化程度高的1年生苗,作为繁殖母株,放入清水中浸泡5—7天,使母株充分吸足水分,促进抑制物质转化和形成根原始体,以提高成活率。2、栽植母株:在巳深耕细整施足农家肥的圃地上,每隔40厘米划线定行距,挖栽植坑,坑的距离依母株的长度而定。于3月下旬将母株斜栽使其与地面的角度成5—10度,一株接一株地栽好,及时浇水,使土壤与母株的根系紧密结合。
Fushan County nursery in the spring of 1985 Populus tomentosus planted bar seedling cultivation trials, in 1986 on the basis of the summary test, this method is used to reproduce 32 acres of Populus seedlings, and achieved good results, the average per mu of 4,100 seedlings, the average Seedling height of 1.5 meters, 1.2 cm diameter, seedlings grow better. The method is: 1, the selection of the mother plant: Select a robust growth, bud full, root development, no pests, high degree of lignification 1 year old seedlings, as breeding mother, soaked in water for 5-7 days, The parent plant fully absorb enough moisture to promote the inhibition of material conversion and the formation of root primordia to improve the survival rate. 2, planted mother plant: in the plow has been plowing fine enough fertilizer on the garden, every 40 cm scribe line spacing, dug planted pit, pit distance according to the length of the parent strain may be. In late March the mother plants oblique planting to the ground angle of 5-10 degrees, planted one by one plant, watering in time, so that the root of the soil and parent plants in close contact.
