The Research of Poyigonum Cymosum on The High- yield Culture Technology
Orthogonal test used on the density of crop and NPK fertilizer impact upon the fresh yield of Poyigonum cymosum and economic benefits. The results showed that the suitable planting density and NPK fertilizer can significantly improve the fresh yield. The yield - increasing effect was PK fer- tilizer 〉 planting density 〉 N fertilizer. The program for the high yield cultivation was plant - row spacing 40 cm x 60 cm, N fertilizer was 10 kg/667 m2 , P fertilizer was 15kg/667 m2 ,K fertilizer was 21 kg/667 m2.
