| 摘 要： | 目的]培育优质、健壮的辣椒苗。方法]以湘研19号辣椒为材料,研究了碳化谷壳培养土和撒施碳化谷壳对辣椒苗生长和苗期病害的影响。结果]碳化谷壳培养土由于容重降低、孔隙度增加,使辣椒苗根数增加、根长增长,能提高辣椒苗定植成活率,缩短缓苗天数。使用碳化谷壳作培养土和撒施碳化谷壳做干燥剂,能显著降低猝倒病和灰霉病发病率,对降低总死苗率也有极显著效果,特别是在冷冬年份效果更加突出。结论]碳化谷壳对培育优质、健壮的辣椒苗是高效的。

| Abstract: | Objective]The aim was to cultivate quality and healthy Capsicum frutescans seedling.Method]The effects of nutrient soil and broadcast application of carbonized rice husks on the growth and pathogenesis of Capsicum frutescans seedling were studied with Capsicum frutescans variety of Xiangyan 19.Result]The results showed that with decreasing of the soil bulk density and increasing of the soil porosity,the number and length of root increased,the days of revival from transplanting cut down,the survival rate of transplanting went up.The morbidity of seedling damping-off and botrytis decreased significantly,and total dead seedling rate also decreased significantly,especially for the cold winter.Conclusion]Using carbonized rice husks to cultivate quality and healthy Capsicum frutescans seedling was efficient. |
