栽培技术 1、选地、整地 选择湿润和有充分荫蔽的地块，土壤以质地疏松、保水力好的壤土或砂壤土为宜。播种前先深翻1遍，结合整地每亩施农家肥2000千克，翻入土中作基肥，然后耙细整平，作畦，畦宽1.2米。 2、繁殖方式 ①根状茎繁殖：于晚秋或早春3月下旬前后选1-2年生健壮、无病虫害的植株根茎，选取先端幼嫩部分，截成数段，每段有3－4节，伤口稍加晾干，按行距22－24厘米，株距10－16厘米，深5厘米栽种，覆土后稍加镇压并浇水，以后每隔3－5天浇水1次，使土壤保持湿润。于秋末种植时，应在上冻后盖一些圈肥和草以保暖。 ②种子繁殖：8月种子成熟后选取成熟饱满的种子立即进行沙藏处理：种子1份，砂土3份混合均匀。存于背阴处30厘米深的坑内，保持湿润。待第二年3月下旬筛出种子，按行距12－15厘米均匀撒播到畦面的浅沟内，盖土约1.5厘米，稍压后浇水，并盖一层草保湿。出苗前去掉盖草，苗高6－9厘米时，过密处可适当间苗，l年后移栽。为满足黄精生长所需的荫蔽条件，可在畦埂上种植玉米。 3、田间管理 生长前期要经常中耕除草，每年于4、6、9、11月各进行1次，宜浅锄并适当培土；后期拔草即可。若遇干旱或种在较向阳、干旱地方的需要及时浇水。每年结合中耕除草进行追肥，与过磷酸钙50千克，饼肥50千克，混合拌匀后于行间开沟施人，施后覆土盖肥。黄精忌水和喜荫蔽，应注意排水和间作玉米。
