小白菜潮汐式栽培专用基质的筛选

对3种不同栽培基质和常规栽培基质（市场销售）在潮汐式灌溉模式下进行小白菜栽培试验，比较小白菜的植物学性状，筛选出适用于潮汐式灌溉的小白菜专用型栽培基质。研究结果表明，处理2（40%茶渣蚓粪、20%泥炭、20%蛭石、20%珍珠岩）培育的小白菜株高、生物量、株幅、SPAD 值均显著优于其他处理，栽培效果显著提高，可推荐作为潮汐式灌溉小白菜栽培的专用型基质。

Screening of Special Cultivation Substrate for Chinese Cabbage with Ebb-and-flow Irrigation

In this paper,we used 3 different special cultivation substrates and 1 common cultivation substrate (for market sale)to take the experiment of Chinese cabbage planting with ebb-and-flow irrigation, and the botany characters of Chi-nese cabbage were observed to screening special Chinese cabbage cultivation substrates with Ebb-and-flow Irrigation. The result showed that the cultivation results of treatment 2 (40% tea leaf and vermicompost, 20% peat, 20% vermiculite, 20%perlite ) were significantly better than others in plant height, biomass, SPAD value, leaves spreading, it could be recom-mended as special cultivation substrates for Chinese cabbage with ebb-and-flow irrigation.
