竹炭对草本花卉生长的影响

通过竹炭颗粒与清水沙等混合物作花卉栽培基质，种植蝴蝶花、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15～25g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15g竹炭颗粒基质种植吊兰各项生长因子最好。

The Influence of Bamboo Charcoal on Herbaceous Flower Growth

Flowering plants Iris japonica, Chlorophytum comosum, Rohdea japonica and others are cultivated on the mixture of bamboo charcoal granules and sand for experimentation. The length and growth condition of root system, quantity of stem leaf is observed. The results are as follows. (1)Bamboo charcoal granules can improve the physical and chemical property of soil, increase its pH value, hole degree and hold water rate, and enhance the content of N, P, K, Ca, Mg, Fe,etc. They also resolve and absorb heavy metallic elements,such as Cu,Zn and Mn. (2) Bamboo charcoal particles can promote the growth of root, stem and leaf, and the forming of bud. With the increase of bamboo charcoal particles they promoted the growth of plants at first and then suppressed them .To add 15 - 25 g of bamboo charcoal granules to any kind of soil results best. (3) The growing factors of flowering plants on soil with bamboo charcoal particles are obviously better than the plants of contrast group.The growing factors of Chlorophytum comosum with 15g bamboo charcoal granules added are the best.
