Water slurry management in the late period of white harvesting, opening and draining water, so that wetting over the winter. In this way, it can ensure the budding of the overwintering and eucalyptus, achieve the purpose of early maturing and high quality, and can prevent the rot of the white rhizomes and the freezing and freezing of the white rhizome caused by the high water level. After selecting and eliminating poor drainage and drainage, in combination with the selection work at the time of picking, we excavate the puppets with high stature, ash and pregnancies, and have a small but fat meat. , white meat, white meat, large and neat shape, harvest basically the same pier. At the same time, before the overwintering of winter, the old stem shoots with high quality alfalfa piers should be replanted at the piers where the alfalfa piers were exhumed, and the high-yield racks should be established for the lunar years. After cutting the white pods and harvesting the old pods, the stalks were cut off and the stubble leaves of the saplings were cut and removed and burned out of the field. In this way, it is not only beneficial to reduce the number of gray ash, reduce the pregnancies, but also help to reduce the winter base of the disease and insects.
