侧柏是北方较好的造林树种及庭园绿化树种。地处西北的青海省,常绿树种较少,而侧柏具有耐旱、抗寒等特性,很适合这一地区生长。近几年随着城市绿化迅速的发展,对侧柏苗的需求量也猛增。为缩短育苗周期,加速繁育侧柏苗,我们于1984年采用搭塑料棚方法育苗,初步取得了效果。一、塑料棚的设置塑料棚搭在通风向阳处,棚为东西向,长不限,宽1.5米,高60厘米,棚间距50厘米,中间挖排水沟。二、播种育苗苗床在搭棚前整好,床面铺20厘米的森林腐植质土,每亩施入磷酸二氮30斤,厩肥4立方米,播种前浇透水。种子为本地产,播前浸泡一昼夜。
Oriental arborvitae is a better afforestation species and landscaping tree species in the north. Located in the northwest of Qinghai Province, evergreen species less, and arborvitae has drought, cold and other characteristics, it is suitable for the growth of this area. In recent years, with the rapid development of urban greening, the demand for arborvitae seedlings also soared. In order to shorten the breeding cycle and speed up the breeding of oriental arborvitae seedlings, we adopted the plastic shed method to nurture seedlings in 1984, and achieved initial results. First, the plastic shed set Plastic sheds take the place in the ventilation, sheds for the east-west to the long, limited to 1.5 meters wide, 60 centimeters high, shed spacing of 50 cm, the middle drain. Second, sowing nursery seedbed in the scaffolding well, the bed shop 20 cm of forest humus soil, applied per acre 30 pounds of phosphoric acid, manure 4 cubic meters, sowing water before sowing. Seed-based real estate, sowing before diurnal day and night.
