塑料泡沫育苗盘作为漂浮育苗方式是不可或缺的基础设施,长期的化工制造不仅造成生态环境的污染,同时造成育苗成本的不断提高。本研究以降低育苗成本,培育优质壮苗为目的,研究了不同苗盘高度和育苗密度对烟苗生长发育及病虫害发生的影响,并分析了轻简育苗的经济效益。结果表明:以苗盘高度5cm、育苗密度160株/盘的育苗盘所育烟苗根系发达,苗株健壮,病害发生率低,综合生理生化指标优于常规育苗盘所育烟苗,经济效益提高1.95元/盘。本试验结果可为环保材料矮化育苗盘开发的规格提供参考。
Plastic foam nursery tray as a floating nursery is an indispensable infrastructure, long-term chemical manufacturing not only caused by the pollution of the ecological environment, while causing nursery costs continue to increase. In order to reduce the cost of raising seedlings and cultivate high quality seedlings, this study studied the effects of seedling height and seedling density on the growth and development of plant diseases and insect pests, and analyzed the economic benefits. The results showed that the root system of nursery stock was nursery seedling with seedling height of 5cm and nursery density of 160 plants per plant. The root system of nursery stock was well developed, the seedling was robust and the incidence of disease was low. The comprehensive physiological and biochemical indexes were better than those of conventional seedling raising tray. Increase 1.95 yuan / plate. The results of this test can provide a reference for the development of dwarf nursery tray for environmental protection materials.
