１９９７年１２月至１９９８年２月，利用不同栽培基质，在玻璃温室与平房室内（均有供暖条件）环境下，进行的龙须豌豆芽菜无土栽培试验表明：冬季平房室内栽培以纯河沙和棉壳、河沙各５０％体积比混合基质最佳；玻璃温室栽培以木屑、河沙各５０％体积比及棉壳、河沙各５０％体积比的混合基质最好。其最佳栽培温度为１８～２３℃。 From December 1997 to February 1998, the soilless culture experiments of Spodoptera frugiperda with glasshouse and bungalow (with heating conditions) under different cultivation substrates showed that winter cabbage was cultivated in pure river sand And 50% volume ratio of cotton hull and river sand mixed matrix was the best. In the greenhouse, 50% volume ratio of sawdust and river sand and 50% volume ratio of cotton hull and river sand were the best. The best cultivation temperature is 18 ~ 23 ℃.
