摘要
探究氨基酸复合微肥对甘蔗产量、品质及土壤残留有效态微量元素的影响,分别应用氨基酸复合微肥500倍稀释液浸种和拌种处理甘蔗种苗,甘蔗生长前期以喷施清水处理为对照,氨基酸复合微肥500倍稀释液进行叶面喷施与沟施。结果表明,氨基酸复合微肥能够促进甘蔗的生长,施用氨基酸复合微肥甘蔗出苗率与分蘖率显著高于对照。施用氨基酸复合微肥的增产增糖效果明显,喷施与沟施较对照分别增产甘蔗19.3%和8.5%,产糖量分别提高14.9%和10.6%。此外,施用氨基酸复合微肥对土壤有效Mn、有效Zn和有效B的供给有一定的改善作用。
The experiment was conducted to study the effects of amino acid compound microelement fertilizer on sugarcane 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.
