摘要：

研究不同浓度供钙量对芦荟植株营养生长和生殖生长的影响，探讨增加芦荟人工栽培品种用以满足原材料市场需求的可能性。以皂质芦荟为研究对象，采用混合基质+营养液的种植方式，在改良霍格兰营养液配方的基础上设置13个不同浓度钙矿质养分处理，人工栽培皂质芦荟植株4个月，测定植株外部形态、植物生长量和繁殖器官等指标生长数据。试验结果表明，除根长、叶片数量、分蘖数量和花梗数量4项指标外，株高、叶片厚度、最大叶片面积、总生物量、地上部生物量、地下部生物量、繁殖器官生物量、花梗高度、蒴果数量和种子数量等10项数据均在110%钙浓度处理中达到最大值；次最大值出现在100%和120% 2个处理中；在0%和500% 2个处理中上述所有测定数据指标均最小。生物量数据显示，地上部器官生物量所占比重最大，繁殖器官次之，地下器官生物量最小。研究证明，皂质芦荟属于适钙植物，11 mmol/L Ca2+浓度霍格兰营养液配方最适合其植株生长发育。

Abstract:

The paper aims to study the impacts of calcium supply with varying concentrations on the vegetative and reproductive growth of aloe plants and explore the possibility of increasing the artificially cultivated varieties of aloe plants to meet the market demand of raw materials. This study took the multifunctional plant Aloe saponaria as the research object, adopted the planting method of mixed substances + nutrient solution, set up 13 different experimental treatments with calcium supply with varying concentrations in collaboration with the modified Hoagland nutrient solution, artificially cultivated A. saponaria for 4 months, and determined the external morphological growth data, plant production data and reproductive production data. The study results showed that except the data of root length, leaf number, tiller number and pedicel number, other determined data including plant height, leaf thickness, maximum leaf area, total biomass, aboveground biomass, underground biomass, reproductive organ biomass, pedicel height, capsule number and seed number all reached the maximum value in the 110% calcium experimental treatment; the secondary maximum values appeared in the experimental treatment of 100% and 120% calcium concentrations; and in the two calcium concentration experimental treatments of 0% and 500%, all the above measured data were the smallest. The experimental biomass data showed that the biomass of aboveground organs accounted for the largest proportion, followed by reproductive organs, and the biomass of underground organs was the smallest. This study has fully demonstrated that A. saponaria belongs to calcicolous plants, the formula of Hoagland nutrient solution with Ca2+ concentration at 11 mmol/L is the most suitable for its plant growth and development.
