4. Nutrients: 65,438+0,500 ~ 2,000 kg of fully decomposed manure is applied as base fertilizer per mu during soil ploughing, and appropriate amount of phosphorus and potassium compound fertilizer is applied during planting, with the dosage of about 20 ~ 25 kg per mu.

5. Pruning: Polygonum cuspidatum grows rapidly, and various weeds emerge in an endless stream. Be sure to remember to weed in time. Otherwise, the nutrients in the soil will be absorbed by all kinds of weeds, and it is necessary to loosen the soil properly to give it a good growth environment.
