“Nitrogen fertilizers of new type formed by coordination of DMPP with ammonium sulfate and urea (ASN+DMPP, urea+DMPP) could reduce markedly nitrate accumulation, increase Vc, amino acid, soluble sugar and Zn content in pakchoi as compared with urea and ammonium sulphate nitrate (ASN), and improve quality, the action of (ASN+DMPP) was more obvious”
