细种条培育毛白杨壮苗,已在我省积累了较丰富的经验。武陟县小徐岗林场,用径粗为0.4—0.8厘米的插条,扦插育苗成活率平均为83.81%,最高达93.1%。每亩平均产苗量6,784株,最高达9,191株。平均苗高2.95米,地径2.04厘米。现简介如下: 1.适时采条为了保证种条生根快、成活多、苗木壮,必须适时采集种条。经验证明,毛白杨以叶片变黄而部分脱落时采条最适宜。具体时间,以11月中下旬至12月上中旬为好。 2.深坑贮藏选择地势高燥、排水良好的地方,挖成深1米,宽1.5米,长2米的贮藏坑。坑底铺沙10
Slender seed cultivation of white poplar seedlings, has accumulated a wealth of experience in our province. Xiaoguang Forest Farm in Wuyi County, cuttings with 0.4-0.8 cm diameter cuttings, the average survival rate of cutting seedlings is 83.81%, up to 93.1%. The average number of seedlings per acre 6,784, up to 9,191 strains. Average height of 2.95 meters, 2.04 centimeters in diameter. Now briefings are as follows: 1. Timely mining In order to ensure the planting of rooting fast, more survival, seedlings Zhuang, must be timely collection of species. Experience has shown that when Populus tomentosides turn yellow and partially shed when the most appropriate mining. The specific time, in late November to early December on as well. 2. Deep pit storage options High dry, well-drained place, dug deep 1 meter, 1.5 meters wide, 2 meters long storage pit. Sand at the bottom of the pit 10
