大多数松属的树种用插条繁殖极难生根,且生长缓慢,又因种条有限,给枝插带来一定的限制。近20多年来,国外采用针叶束扦插代替枝插,在许多种上获得成功。国内周心铁等人采用水培提高了湿地松针叶束的生根力。但目前针叶束扦插在生产上大面积推广,仍有局限性。为了提高松属造林、绿化树种的扦插生根能力,探索适于生产上大面积应用的扦插繁殖技术,我们于1981—1982年,进行了乔松、油松、华山松、白皮松不同扦插条件,不同药剂处理促进针叶束扦插生根的试验,现将初步结果报告如下:
Most species of Pinus thunbergii planted with cuttings very difficult to root, and slow growth, but also because of the limited species, to stick to some restrictions. In the past 20 years or so, foreign softwood cuttings have been used instead of cuttings for success in many species. The use of hydroponics in China has increased the rooting ability of Pinus elliottii. However, there are still some limitations in the popularization of softwood cutting in production. In order to improve the afforestation, afforestation afforestation ability of cutting trees, explore suitable for the production of large areas of cutting propagation technology, we conducted in 1981-1982, pine, Pinus tabulaeformis, Pinus thunbergii different cutting conditions, different Pharmacy to promote needle cutting cutting rooting test, the preliminary results are reported as follows:
