摘　　要：研究了五彩椒在硅藻土、草炭、蛭石、珍珠岩4种组分按不同比例配成的5种混合基质下的生长差异,试验采用了一种自制的自动连续精确控水盆栽装置,并为所有处理设置了相同的供水吸力,用于分析5种不同基质的吸水能力。结果表明:硅藻土是一种优良的基质添加成分,其吸水、保水性能均优于蛭石和珍珠岩;试验同时得出:50%草炭+25%蛭石+25%硅藻土、40%草炭+20%蛭石+20%珍珠岩+20%硅藻土2种基质配方比其它基质配方更理想,相对于其它3种基质配方,这2种配方基质理化性质更好,吸水、保水、保肥能力都强于其它基质量配方,栽培下的五彩椒生理指标和形态指标更优,值得进一步研究与推广。The effects of diatomite medium proportion on vegetative growth of pot Capsicum annuurn was studied in this paper; In order to testing the suck water capability of the five difference medium, a new sort of precise water control potted plant device was taken for ttxis experiment with the same water supply tension. The results were indicated as follows：the diatomite was a good medium accession, the capability of sucking and holding water was better than vermiculite and perlite medium; the two kinds of medium proportion （50% turf＋25% vermieulite＋25% diatomite and 40% turf-t-20% vermiculite＋20% perlite ＋20% diatomite） Could significantly promote the shape and physiology growth of Capsicum annuurn ; the physicochernical characteristics of them were better than the other three medium proportion, the two kinds of medium proportion had an excellent holding water and nutrition and could be used in the gardening.
