土培条件下不同剑麻品种生长差异研究

Comparison on the growth of different sisal cultivars under pot experiment

通过土培试验,对不同剑麻品种的生长情况进行了比较,结果表明:剑麻主栽品种H.11648的株高和地上部生长量等指标均具有明显的优势,其根系生长量和根冠比处于适度水平,根系保水力较差;与南亚2号相比,H.11648地上部干重增幅达38.10%;不同品种剑麻地上部生长趋势表现为H.11648>奥西114>假菠萝麻>为孤叶龙舌兰>南亚2号。

Pot experiment was used to evaluate the growth of different sisal cuhivars. The results showed that the height and dry weight of shoot of H.11648 were the highest among 5 cuhivars. The dry weight of root and root/shoot of H.11648 were also on moderate level. The water-holding capacity of H.11648 was worse than others. The dry weight of shoot of H.11648 was 38.10% higher than the Nanya No.2. Obviously, the growth of H.11648 was better than other cultivars.
