摘要
从甘南地区近几年连续发生春旱,给农业生产增收带来严重影响这一实际情况出发,对灌后覆膜和垄作栽培前后黄芩土壤含水量,及相应的黄芩生物量变化情况进行了比较分析。结果表明:灌后覆膜技术的保墒效果要优于垄作栽培技术,提高了黄芩的抗旱能力。灌后覆膜栽培技术能有效的提高黄芩的产量,每公顷纯收入增加500～900元。
There was the spring drought in Gannan County in recent years,and it influenced the agricultural production.We investigated coated after irrigation technique,soil water content of Scutellaria baicalensis and cultivation situation in Gannan County based on the climate characteristics and advanced a new cultivation mode of Chinese herbal medicine,coated technique after irrigation based on some biological characteristics about seeds and root of S.Baicalensis.The yield of S.baicalensis after filling and coating line and ridge tillage cultivation will increase,and the income will increase by CNY 500.00-900.00 per hectare.
