摘　　要：玉米秸基质是一种新开发的替代草炭的基质,研究其在园艺作物栽培和育苗中的配套应用技术有重要意义。该文以番茄为试材,采用正交试验设计,研究了蛭石与发酵玉米秸基质的复配比例、烘干鸡粪添加量及基质相对含水率对玉米秸基质穴盘育苗的影响。结果表明:3因素对番茄幼苗地上部生长影响的主次顺序是鸡粪添加量>基质相对含水率>基质配比,对地下部生长影响的主次顺序是基质相对含水率>基质配比>鸡粪添加量;通过验证试验,综合考虑育苗效果及经济性得出最优组合处理为:基质相对含水率85%;玉米秸基质︰蛭石(V︰V)=1︰1;鸡粪添加量为每穴盘15g。该试验结果为玉米秸基质应用及新基质开发提供了参考。Corn stalk is a kind of newly substrate that can replace peat. It is important to study the application technique for horticultural crops cultivation and seedling production. The effect of the volumetric ratio of vermiculite to corn stalk substrate, the adding quantity of chicken manure and the relative moisture content on the growth of tomato plug seedling were studied by using orthogonal test design. The results showed that the important order of different factors to the above-ground growth of tomato seedlings was： the quantity of chicken manure 〉 the relative moisture content 〉 the volumetric ratio of vermiculite and chicken manure, while the order to the under-ground growth was： the moisture content 〉 the volumetric ratio of vermiculite and corn stalk substrate 〉 the quantity of chicken manure. The optimal combination was obtained in this experiment, which the relative moisture content was 85% and the volumetric ratio of vermiculite to Corn stalk substrate 1：1, and the quantity of chicken manure 15 g in per plug trays. The results of this experiment provided a useful reference to the utilization of corn stalk substrate and developing new type substrates.
