我场于1980—1981年先后从江苏省林科所引进杂交柳10个品系,为了解决穗条不足的困难,进行了短穗扦插繁殖,获得了成功.现将情况简报如下:试验地位于长江下游北岸的冲积平原,土壤为小粉砂土,地力较瘠薄,有机质为0.91%,全氮0.39%,有效磷15PPm,有效钾100PPm,PH值为7,土层较厚,排灌条件较好,保肥保水能力较差.前茬为水稻田和松类苗圃地,早春起苗后人工深翻30厘米,施家杂肥每亩80担,磷肥每亩50斤,再耕翻两次,深20厘米,耙细作宽1.1米小床扦插.
I field in 1980-1981 successively from Linke, Jiangsu Province, the introduction of hybrid willow 10 strains, in order to solve the problem of insufficient spike, short cuttings propagation, and achieved success.The present briefing is as follows: The experimental site in the Yangtze River The alluvial plain on the north bank of the lower reaches is of small silt soil with relatively poor soil fertility and organic matter of 0.91%, total nitrogen of 0.39%, available phosphorus of 15 ppm, available potassium of 100 ppm, pH of 7, thick soil layer, Preservation of water retention capacity is poor.Pre-crop paddy fields and pine nursery, early spring after the artificial deep sowing 30 cm, Shi Jia miscellaneous fertilizer 80 per mu, phosphate fertilizer 50 pounds per mu, then plowing twice, deep 20 cm, rake made for small 1.1 m wide bed cutting.
