沙棘硬枝扦插繁育技术研究
Study on Hardwood Cutting Propagation Technique of Hippophae rhamnoides
摘要
Abstract
To explore the effects of different factors on the rooting indicators of sea buckthorn.Based on single-factor experiments on different cut shapes,different cut lengths and different varieties of sea buckthorn hardwood cuttings,L9(34)orthogonal cutting experi-ments with different substrates,different hormones,hormone concentrations and soaking times were carried out.The results showed that the incision shapes of different cuttings varied significantly.The best-performing one was the horse ear shape,followed by the horseshoe shape,and the worst was the flat shape.The survival rates of the three treatments were 72.4％,66.9％,and 60.6％respec-tively,and the rooting effect indices were 1.15,0.68,and 0.39.The rooting traits of cuttings of different lengths were significantly dif-ferent.The cuttings with a length of 15 cm showed the best performance,followed by 20 cm.The survival rates were 74.5％and 69.9％respectively,and the rooting effect indices were 1.17 and 0.71.There were significant differences among different varieties.The optimal variety was Yulu No.1,followed by Zhongji No.3.The survival rates were 72.8％and 70.3％respectively,and the rooting effect indices were 1.2 and 0.6 respectively.The rooting conditions of different substrates(A),hormone types(B),hormone concentra-tions(C),and soaking times(D)were significantly different(P＜0.05).The best combination was A1B3C3D3,followed by the combination A2B3C1D2.The main factor affecting the rooting rate was the substrate type.In conclusion,when taking cuttings of sea buckthorn hard-wood,the horse-eared cut was the best treated.The best rooting index was achieved when the cuttings are 15 cm long.The rooting manifestations of different varieties were as follows Yulu No.1＞Zhongji No.3＞Hongji No.1＞Zhongji No.4.The combination of using fine sand+perlite+vermiculite as the substrate and treating cuttings with ABT rooting agent at a concentration of 300 mg·L-1 for 1 hour had the best rooting effect for sea buckthorn hardwood cuttings.These findings can provide technical support for the efficient propaga-tion of high-quality sea buckthorn seedlings in arid and semi-arid areas.关键词
