(a) remove weeds
The konjac root system is shallowly distributed. To prevent the young roots and underground stems of the cultivating grasses from being damaged, the normal growth of the plants is affected, and the weeds can be manually removed. However, it should be noted that people can only pull grass in the ridge, do not step on the ridge to prevent the underground roots.
(b) Qinggou earth
The konjac is afraid of drought and it is not suitable for impregnation. Therefore, in the rainy season, especially after the rainstorm, the cultivated fields should go to the ground for inspection and drain the ditch to ensure the open waterway. In combination with the ditch, the fine soil in the trench is cultivated on the ridge surface. Fertilize the soil 2-3 times, in order to facilitate the formation of bulbs, enlargement and sub-floods are not exposed, and can enhance the wind resistance of konjac.
(3) Scientific fertilizer
The ground topdressing is mainly used for cultivating and defecate water when the konjac sprouts and leaves, or it can be used to dry the pig feces residue among the plants, and the soil penetrated by the rainwater is used for the konjak roots. To avoid burning roots, it is best to use manure dressing. For the konjac lack of base fertilizer can be applied compound fertilizer.
(D) Prevent Diseases
Konjac is mainly caused by soft rot and white peony disease. After konjac is unearthed, it begins to spray and prevent disease. It can use 72% of agricultural streptomycin 2,500 times or thiophanate-methyl 500 times, etc., and spray every 7 days. Spray 3-5 times. After the konjac has sprouted and unearthed, check the condition at any time and find the diseased plant. Immediately remove the soil or burn it with soil. Do not throw it into the septic tank or the corner of the field. Sprinkle the lime in and around the nest and step on the soil. Prevent rainwater from removing germs and increase infection.
