Effects of Combined Application of Chinese Medicine Dregs Fertilizer with Various Kinds of Fertilizers and Microbial Agents on Growth,Yield and Quality of Potatoes
In order to reduce the use of chemical fertilizer,increase yield of potato,and promote the scientific utilization of the residue of traditional Chinese medicine,a field experiment comprising five treatments was conduc-ted in Yulin.The study involved the investigation of the growth indexes for potatoes and the determination of both potato yield and quality.The results showed that the treatment including 10％reduction of chemical base fertilizer,Chinese medicine dregs fertilizer,compound microbial fertilizer,and microbial agent treatment(N5)significantly increased the length of rhizome and stolon,the number of tubers,the yield of commercial fruit,the content of re-ducing sugar and starch in tubers.However,it markedly reduced the yield of inferior potato fruit.Compared with the control treatment,the stolon,tuber number and commercial fruit yield of N5 increased by 223.28％,99.40％and 49.83％,respectively,but the inferior fruit yield decreased by 55.47％.In conclusion,N5 has demonstrated positive effects on the growth of stolons,tuber proliferation,and the conversion of substandard fruits into marketable ones.Therefore,N5 proves to be a viable solution for an improved fertilization technology scheme,realizing the the utilization of Chinese medicine residue fertilizer,the reduction of fertilizer application and the improvement of pota-to yield and quality.
