Abstract:

The experiment was conducted to study the effects of amino acid compound microelement fertilizer on sugar cane yield, quality and soil residual available trace elements. Applied 500-fold dilution of amino acid compound microelement fertilizer to dress and soak sugarcane seed set. At the same time, foliar spraying and furrowing 500-fold dilution of amino acid compound microelement fertilizer in sugarcane vegetative growth phase comparing with to spraying water. The results showed as follows: amino acid compound microelement fertilizer had promoted the growth of sugarcane. Sugarcane emergence rate and ratio of tiller was significantly higher than control treatment. Amino acid compound microelement fertilizer was significantly increased the sugarcane yield and sugar yield. Spraying and furrowing application fertilizer of sugarcane yield was increased by 19.3% and 8.5%, respectively. Sugar yield was increased by 14.9% and 10.6%, respectively. Furthermore, soil available Mn, Zn and B was improved to meet sugarcane requirements when amino acid compound microelement fertilizer had applied.
