通过竹炭颗粒与清水沙等混合物作花卉栽培基质,种植蝴堞花、吊兰、万年青等花 卉试验。结果表明:(1)竹炭颗粒能改善土壤的理化性质,提高土壤的pH值、孔隙度和持水 率,提高速效N、P、K,Ca、Mg、Fe的含量,分解和吸附Cu、Zn、Mn等重金属元素。(2) 竹炭颗粒基质能促进植物根、茎、叶生长和花蕾的形成,且随其用量的增加出现先促进植 物生长后抑制植物生长的现象,且以每样土壤中添加竹炭颗粒15-25 g为最佳。(3)不同竹 炭颗粒配比组花卉各生长因子明显好于对照组。以15 g竹炭颗粒基质种植吊兰各项生长因 子最好。
Bamboo charcoal granules and water through the mixture of sand and other flowers for the cultivation of media, planting flowers such as butterfly, spider plant, Evergreen and other flowers test. The results showed that: (1) Bamboo charcoal granules can improve the physical and chemical properties of soil, increase the pH value, porosity and water holding capacity of soil, increase the content of available N, P, K, Ca, Mg and Fe, , Mn and other heavy metal elements. (2) The bamboo charcoal granular matrix can promote the growth of plant roots, stems and leaves and the formation of flower buds, and with the increase of the amount of bamboo charcoal granules, the phenomenon of plant growth is promoted after the growth of plants is accelerated. In addition, bamboo charcoal granules 15-25 g is the best. (3) Different bamboo charcoal granules ratio of each group of growth factors were significantly better than the control group. With 15 g bamboo charcoal matrix cultivation of Chlorophytum all the best growth factors.
