Water-planted taro tiller cutting method

The invention relates to a water-planted taro tiller cutting method. 2-3 times of tiller cutting are performed at the earlier stage of tiller growth, son taros are reserved when plants grow to reach 80-100 cm, 3-5 son taros are reserved for each mother taro, and the mass of each single son taro is controlled to be 200 g or below; field water is thoroughly drained before tiller cutting, cuts are formed in the plants when the son taros are removed during tiller cutting, agricultural streptomycin sulfate or dexon is sprayed after tiller cutting, and irrigation is performed after wound healing. The growth and mass of mother taros are not affected while the son taro yield is increased, nutrition can be also saved on the contrary, and growth of taro plants and the mother taros is promoted. 本发明涉及种水植香芋除蘖方法，香芋生长前期进行除蘖2-3次,植株长到80-100厘米具绝对优势时,开始留子芋,每株母芋留3-5个子芋,将单个子芋的质量控制在200克以下；除蘖前排干田水,除蘖摘除子芋时给植株造成伤口,除蘖后喷施农用硫酸链霉素或敌克松,伤口愈合后再灌水。增收子芋的同时不但不影响母芋生长和质量，反而能节约营养，促进香芋植株和母芋的生长。
