麦冬喜温暖而潮湿的环境，多种植在海拔460～520m的涪江两岸的Ⅰ、Ⅱ级阶地上。最适土壤为棕潮沙泥。该土壤母质复杂，矿质养分丰富，有机质含量适宜，中性，含钙，微生物活跃。物理性状好，土层深厚，地上水位高，结构良好，上松下紧，透气、透水、回润好。土壤水、气、热、肥协调，能满足麦冬生长发育之需，种植的麦冬质量好，产量高。

Ideal ecological condition for the growth of Ophiopogon japonicus(L. f) Ker-Gawl. is a warm and moist environment. It is generally planted along the banks of Fujing River,460～520m above sea level. The best soil will be brown and sandy with complicated parent material,rich in mineral,calcium and organic matters,neutral and vivid with bacterial activity. It has a deep soil horizon,shallow water level,loosely composed on the surface while tightly beneath,good permeation for both air and water. Such a concert among soil,water,air,heat and manure will result in a high yield of the plant to satisfy the demand of high quality product.
