摘　　要：荸荠大田分蘖期割除母株技术是一项荸荠栽培新技术,已在浙江荸荠产区推广应用,具体方法为:待移栽后的大田荸荠母株平均分蘖苗达到6~7株时,用镰刀从土表下1~5 cm处的基部割去母株地上部全部叶状茎,并收集转移到田外销毁。与常规栽培的不割除母株相比,割除母株处理的荸荠秆枯病病秆率降低4.6~7.4个百分点、病情指数减少2.2~3.9;无效分蘖减少2.3~7.5株·m^(-2),田间叶状茎生长较整齐;单位面积球茎数增加17.0~25.2粒·m^(-2),增产15.5%~20.9%。荸荠分蘖期割除母株是一项降低病原菌基数,减少秆枯病病菌感染,拓展球茎生长空间,提高产量,操作简易而行之有效的创新技术。The mother-plant-cutting technology(MPC)applied during chufa tillering stage in fields have been applied and extended in chufa producing areas in Zhejiang Province.The detailed procedure is when the tiller number reached6-7plants,cut all leafy stems of mother plant above the ground by a sickle digging into1-5cm under the soil surface.The cut debris was moved out from the fields.Compared with the mother-plant uncut plant,the stem blight rate of mother-plant-cutting plant was reduced by4.6-7.4percentage point,and the disease index(DI)was reduced by2.2-3.9.The number of inefficient tiller decreased by2.3-7.5plant per m2.Besides,the yield was increased by15.5%-20.9%,and the number of corm increased by17.0-25.2per m2.Mother-plantcutting technology is a simple and high efficient innovative technology for chufa pathogen reduction and yield increase.
