荷花基质无土栽培技术研究

Effect of Different Culture Media and Nutrient Solutions on Lotus Growth in Soilless Culture:

本研究试验了无土栽培荷花的各项生长指标和观赏价值均高于常规的土培荷花。经筛选的浓度为０．０２％的Ｈ２号培养液，基本符合荷花生长发育所需的营养要求；基质以富含有机质、保肥能力强的泥炭、和复盖在上的卵石所组成的混合基质效果为好，其次为黄沙。上述培养液和基质，可在外销种藕与盆景荷花的规模化生产中，推广应用。

The experiment results showed that the growth status and view valuation of lotus in soilless culture were better than that in soil culture No H 2 nutrient solution with a percentage of 0 02 concentration obtained by selection was fit for the growth of lotus The best medium was the cobble and the underneath peat which contains rich organic matters and possesses strong characteristic of fertilizer conservation Next to the cobble and peat medium is the yellow sand The nutrient solution and and culture medium mentioned above can be used extensively for lotus in soilless culturef or national and international markets
