不同覆盖基质粒径对草花种子出苗质量的影响

摘要

草花在园林景观利用的地位越来越来高，草花生产育苗技术是关键环节。蛭石且有可靠的理化性质，是作为草花种子发芽的上好覆盖材料，不同粒径的蛭石对草花的发芽生长有直观影响。试验表明：三级蛭石比二级蛭石作为覆盖基质对柳穿鱼和福禄考种子发芽率有提高，柳穿鱼和福禄考种苗根长、根重有提高。%Herbous flower used in garden landscape is more and more extensive, it＇s seedling production technology is the key of. Vermiculite has reliable physicochemical properties, is as a good cover material of a flower seed germination, different diameter of the vermiculite has visual effect for the germination growth of herbous flower. Experiments show that： The three grade vermiculite as coverage, Linaria and Phlox seed germination rate has improved than two; Linaria and Phlox seedling root is more length, root weight is more increase.
