腐熟玉米秸秆基质在翠菊育苗上的应用

目的]探索新型的花卉育苗基质。方法]用腐熟玉米秸秆配制育苗基质,设5种基质配比,3次重复,随机区组,研究其对翠菊（Callistephus chinensis（L.）Nees）幼苗质量的影响。结果]翠菊幼苗在处理③（腐熟玉米秸秆∶含10%腐熟鸡粪的园土=1∶3）基质上生长最好,苗期指标与其他处理比均达到显著差异（P〈0.05）,即叶片数为19.1片,株高为6.32cm,茎粗为3.48mm,地上干重为0.81mg,地下干重为0.41mg。结论]腐熟玉米秸秆完全可以替代草炭作为育苗基质的组份。

Application of Well-composted Corn-stover Substrate to China-aster(Callistephus chinensis)Seedling

Objective] The aim was to explore new nursery substrate for flower growing.Method] 5 different mixture ratios of well-composted corn-stover substrate were designed,after three times' repetition and random grouping,their effects on China-aster(Callistephus chinensis(L.)Nees)seedling were studied.Result] Aster seedlings grew best on the treatment 3 of substrate(well-composted corn stalks∶soil with 10% chicken manure=1∶3),whose seedling stage index was significantly different from that of other treatment(P<0.05).That is,there were 19.1 leaves,the plant was 6.32 cm high,diameter was 3.48 mm,the shoot dry weight was 0.81mg,root dry weight was 0.41 mg.Conclusion]The well-composted corn stalks could replace the peat as growth substrate components.
