摘要: 选用4 种营养液配方栽培巨鹫玉( Ferocactus horridus) 和金盛球( Echinopsis calochlora) 两种仙人球, 以泥炭/ 河沙混合基质栽培为对照。结果表明: 经100 d 种植, 供试的仙人球在这4 种营养液配方静置水培中均能正常生长, 而且生长速度显著大于基质栽培或与之相当; 在4 种营养液配方中, 巨鹫玉在完全硝态氮的配方处理中球体质量的增加比基质栽培的快1 倍以上, N、P、K的吸收量也显著高于其它含有铵态氮配方的; 而金盛球在所有营养液配方中生长量均显著高于基质栽培, 球体质量增长量超过基质栽培的1 倍以上, 4 种配方间无显著差异。水培仙人球是促使球体快速增长的良好栽培方式。

Abstract: Two kinds of ball cactus ( Ferocactus horridus and Echinopsis calochlora) were grown in a still hydroponics with four formulae together with a peatmoss medium as control to study the adaptability of those plants to nutrient solution culture. The results showed that two of the ball cactuses tested could growth well in solution culture , in which the growth rate was significantly higher than or equal to that in peatmoss culture. Among the four solution culture formulae , formula 4 had the highest biomass increment and uptake of N , P and Kfor Ferocactu horridus. The biomass of Echinopsis calochlora did not differ significantly among the four formulae , but significantly increased higher than medium culture. This study indicated that ball cactuses could grow well in nutrient solution culture. The nutrient solution culture is a good plantation methods for ball cactus.
