穴盘育苗技术在甜椒育种中的应用研究

Research on Plug Seedling Technology in Sweet Pepper Breeding

从甜椒穴盘苗种子发芽势、秧苗素质以及定植后植株生长过程中坐果和抗病性等方面,研究了甜椒穴盘育苗的优势以及幼苗生长过程中的管理方法。结果表明:不同的种子处理方法,对甜椒种子发芽势、秧苗素质以及定植后植株坐果和抗病能力等各方面有显著影响;不同的育苗基质配比,对甜椒种子发芽率影响不显著,但对秧苗素质影响显著;植株开花前不同的化控方法,对植株生长过程中的坐果和抗病性有显著影响。

The character of plug seedling and management methods in seedling-growth process of sweet pepper were studied by the sprouting tendency of seeds, quality of seedling, the fruit condition and anti-disease ability in the plantgrowing process of sweet pepper. The results showed that the different seed treatment methods had the important role on the germination potential of seeds, the seedling-quality and the plant-growth after planted. Different substrate proportion had no effect on the sprouting tendency of sweet pepper seed, but evidently affected the seedling-quality. The different methods of chemical regulation before flowering significantly affected fruit condition and anti-disease ability in the plant-growing of sweet pepper.
