摘要:随着水草愈发被人们所认识,水草养殖业也在加速发展中,但本地水草产业却一直处于空缺状态。本课题即通过对市场上已有相关栽培方式的分析、实验,开发出一种新的以草炭为主材料,按比例混合颗粒控施肥、淀粉、阿拉伯胶、多菌灵等制作而成的草炭块作为模块栽培基质。通过对草炭块中N,P,K含量的检测,两种植株的栽培观察,以及营养液水培实验,证明草炭块可以作为观赏水草模块化栽培基质。61962

The development and application of ornamental grasses modular cultivation matrix of research
Abstract:Nowadays more and more people know about the aquatic plants, aquatic breeding industry is speeding develop,but local aquatic industry has been vacant. This subject is based on the analysis and the experiment of the related cultivation way already on the market, to develop a new module cultivation substrate made by peat block and part of Granular fertilizer, starch, gum Arabic, carbendazim. Through the N, P, K content detection of peat block, survey the growyh of two kinds of aquatic plants and the nutrient water culture experiments prove that the peat block can be the module cultivation substrate to cultivate ornamental water grass.
Key words: ornamental aquatic plants ; Modular cultivation
