摘要:
为了明确氨基酸增值磷肥对黄褐土中的磷素有效性及相关酶活性的影响,本研究采用室内土培方法,设置不施磷肥(CK)、施普通磷肥(P)和施3种氨基酸增值磷肥[添加0.5%氨基酸的氨基酸增值磷肥(AP0.5）、添加1.0%氨基酸的氨基酸增值磷肥(AP1.0)和添加5.0%氨基酸的氨基酸增值磷肥(AP5.0)]共5个处理,分别测定不同土层、不同培养时间土壤磷素有效性和碱性磷酸酶活性。结果表明,0～20 cm土层土壤从培养第7 d开始,AP0.5、AP1.0、AP5.0处理pH显著低于CK和P处理；40～60 cm土层土壤从培养第7 d开始,各处理pH显著低于CK,且都在第60 d达到最低值。土壤中有效磷和Ca-P含量与CK相比显著提高。不同深度土层中氨基酸增值磷肥对土壤碱性磷酸酶活性的促进作用表现不一,总的来看,以5.0%氨基酸添加量的氨基酸增值磷肥作用效果较好。本研究结果为小分子物质活化磷肥性能提供了理论依据。
Abstract:
In order to clarify the effects of amino acid value-added phosphate fertilizer on phosphorus availability and related enzyme activities in yellow cinnamon soil, the indoor soil culture method was adopted in this study. Five treatments were set up: no phosphate fertilizer (CK), ordinary phosphate fertilizer (P) and amino acid value-added phosphate fertilizer with 0.5% amino acid (AP0.5), amino acid value-added phosphate fertilizer with 1.0% amino acid (AP1.0) and amino acid value-added phosphate fertilizer with 5.0% amino acid (AP5.0). Soil phosphorus availability and alkaline phosphatase activity were measured in different soil layers and different incubation time. The results showed that the soil pH of AP0.5, AP1.0 and AP5.0 treatments was significantly lower than that of CK and P treatment in 0-20 cm soil layer from the 7th day of culture. From the 7th day of culture, the pH of 40-60 cm soil layer was significantly lower than that of CK, and reached the lowest value on the 60th day. The contents of available phosphorus and Ca-P in soil were significantly higher than those in CK. The promoting effect of amino acid value-added phosphate fertilizer on soil alkaline phosphatase activity in different soil layers was different. In general, the effect of amino acid value-added phosphate fertilizer with 5.0% amino acid addition was better. The results of this study provide a theoretical basis for the activation of phosphate fertilizer by small molecular substances.
