施用硫酸铵对饲料玉米养分吸收和产量构成的影响
Effects of Ammonium Sulfate on Nutrient Uptake and Yield Components of Forage Maize
摘要
Abstract
[Objective] To clarify whether the amount of nitrogen,ammonium sulfate and urea are different in the supply of nitrogen for forage maize.[Method] 4 treatments were set up to determine organic matter,pH,available N,P and K of foundation soil,the available N content of 0-20 cm soil in mature period,the nutrient content of soil,main nutrient absorption,and corn yield of forage maize.[Result] The results showed that the available nitrogen content under OPT was the lowest,while the available nitrogen content under FT was the highest;Although there was no significant difference between the dry matter of maize leaves and the whole plant,the leaf dry matter,stem dry matter,ear skin dry matter and grain dry matter were different;The application of ammonium sulfate fertilizer could significantly promote the absorption of N,P2O5 and K2O;The ammonium sulfate could significantly prompt the absorption ratio of P2O5 with the same amount of nitrogen application;The absorption ratio of K2O was significantly lower than that of CF,OPT and OPT treatments;There were no significant difference between forage corn rows per ear and kernels per row;Under the condition of equal nitrogen,applying ammonium sulfate fertilizer could increase the yield of forage maize and increase the nitrogen supply during the whole period.[Conclusion] Thus,Compared with urea,ammonium sulfate fertilizer could increase the yield of forage maize under the condition of equal nitrogen supply.关键词
