繁殖方法
种子繁殖:7-10月果实成熟,用育苗移栽或直播法。9月上旬进行育苗,播后覆盖少许草皮灰及薄层稻草,浇透床土,一般1-2星期后出苗,揭去稻草。待苗高6-8厘米时,进行移植。按行株距20厘米×15厘米定植。
栽培技术
生长期管理进入生长期,需追肥1次,每亩施尿素12。追肥后浇1次透水,待水下渗后23天进行中耕松土,保持土壤疏松。生长期适当增加中耕次数,有利于改善毛茛根系生长环境,促根深扎。一般生长期要进行3次中耕,特别是干旱时和下雨过后,进行中耕十分有效。生长期田间杂草会与毛莨争夺养分、水分和空间等,会影响毛茛生长。要见草及时拔除。同时夏季洪涝多发,应注意防洪排涝。
病虫防治
病害有病毒病。在高温高湿季节偶尔少数植株发生病毒,使受害叶片黄萎,发病时可立即拔除病株。 虫害有地老虎咬断幼苗,可用毒饵诱杀。生长期间,有红蜘蛛为害,可用乐果乳剂2000倍液喷杀。 [1]
