火棘容器育苗技术研究

采用L₉（3⁴）正交实验设计方法,进行了基质配比、种子处理方法和容器规格对火棘出苗率、苗木生长质量影响的研究。结果表明:不同基质配比、种子处理方法、容器规格对火棘出苗率、苗高、地径、根系及生物量等指标均有显著影响。经多重比较分析,提高火棘容器播种出苗率及苗木质量的最佳组合方案为:先将种子消毒后,用100 mg/kg GA₃溶液浸种4 h,然后将种子与湿沙按1:3的比例混合层积于瓦盆内,置于室温（18～23℃）催芽,待1/3种子咧嘴后,播种在规格为12 cm×15 cm,装有腐殖土55%+河沙20%+有机肥22%+过磷酸钙3%基质的容器中,出苗率达91.63%,平均苗高为11.5 cm,地径0.55 cm。

Research on Pyracantha fortuneana Container Seedlings Technology

Using orthogonal experimental design methods,studied the influence of the substratum proportion,seed treatment methods and container dimension on the rate of emergence of Pyracantha fortuneana and seedling growth quality.The results showed that different substratum proportion,seed treatment methods and container dimension had an obvious influence on the rate of emergence of Pyracantha fortuneana,height of seedling,stem base,root system and phytomass.After doing many comparison,the best combination treatment to improve the rate of emergence and the quality was as follows:sterilizing seeds first,and soaking seeds for 4 h with 100 mg/kg GA₃,and then mixing seeds and wet sand in mproportion of 1:3 and stacking them in the earthen basins under the room temperature（18～23℃）to accelerate germination.After 1/3 seeds burst,plant them in the 12 cm×15 cm container with 55%humus,20%river sand,22%organic fertilizer and 3%calcium superphosphate,then we can get the rate of emergence of 91.63%and the average height of seedling of 11.5 cm and stem base of 0.55 cm.
