河北杨是扦插难于生根的树种,我们于1983—1985年连续三年采用塑料小棚人工间歇喷雾法进行嫩枝扦插试验,取得了较好的效果。一、材料和方法试验地设在本院苗圃内。从母树上选取当年萌生的生长健壮、半木质化嫩枝,剪成18—20厘米长插穗,放容器中备用。插床长6—10米,宽1.2—1.4米,床深30厘米。床面上铺15厘米河沙(pH6—7)作插壤。苗床经充分曝晒后,用1/1,000的多菌灵消毒,含水量保持20—30%。床上搭塑料薄膜棚,棚内设喷灌管道。5月底开始扦插,插穗随采随插。插穗下切口应靠近节间,插后要压实。
Hebei Yang is the root of cuttings difficult to root species, we in 1983-1985 for three consecutive years using plastic shed artificial intermittent spray method for cutting shoots, and achieved good results. First, materials and methods Experimental set up in our nursery. Select from the mother tree grew robust, semi-lignified shoots, cut into 18-20 cm long cut, put the container spare. Slitting bed 6-10 meters long, 1.2-1.4 meters wide, 30 cm deep bed. On the bed spread 15 cm river sand (pH6-7) for intercalation. Seedbed after full exposure, with 1 / 1,000 carbendazim disinfection, water content to maintain 20-30%. Bed plastic film shed, shed shed irrigation pipe. The end of May cuttings, cutting plucked with mining. Cutting cuttings should be close to the internode, insert to be compacted.
