Pinellia tuber rot prevention method

The invention discloses a Pinellia tuber rot prevention method. The method comprises the steps that step one, one week before the sowing of Pinellia Ternate, soil blocks are deeply ploughed by utilizing large furrow plow or disc plow to a depth of 30 centimeters or above, the inherent plow tillage is broken to be completely broken up; step two, one day before the sowing of Pinellia Ternate, the soil blocks are spun finely and raked flatly by utilizing a rotary tiller, and normal sowing is conducted. According to the Pinellia tuber rot prevention method, the inherent plow tillage is broken up, the soil moisture of sowing soil layer is infiltrated down rapidly, the residence time of water content around the tuber of Pinellia Ternate is greatly reduced, the rot disease incidence of seed stem and the first grade bulbil is essentially reduced; test results show that the Pinellia tuber rot prevention method is effective in decreasing the rot rate of the tubers of Pinellia Ternate by 81.6%, the rot rate of Pinellia
