Rational utilization of fertilization in high-yield cultivation of sweetpotato

摘要：

Based on formula fertilizer,the technology of separated layer fertilization provide nutrient with fertilization requirement in different growth period of sweetpotato.Its effect on increasing root yield is better than formula organic fertilizer cultivar and general cultivar.The mechanism of highly-yielding is increasing photosynthesis leaf area,improving net assimilation rate and regulating the distribution of photosynthate.
