Effects of "3414" Fertilization Effect Test on the Yield and Economic Benefit of Sagittaria sagittifolia
摘要
Abstract
[Objective] To screen the optimal fertilizer formula,and to lay foundation for the research on special fertilizer for Sagittaria sagittifolia production.[Method] "3414"Fertilization Effect Test was carried out.The yield of S.sagittifolia in each treatment was detected.The effects of N,P and K treatments on the yield and economic benefit of S.sagittifolia were researched.And the optimal fertilizer application ratio was obtained.[Result] N,P and K had relatively good effects on the yield of S.sagittifolia.Treatment N2P2K3 showed the optimal fertilizer application ratio,its yield was 18 397.80 kg/hm2,yield increasing rate was 104.77%,and net income increase was 80 317.35 Yuan/hm2.N fertilizer had the greatest impacts on the yield of S.sagittifolia,followed with K fertilizer;while P fertilizer showed the poorest impacts.[Conclusion] The fertilizer application for highest yield of S.sagittifolia was N 446.70 kg/hm2,P2O5 68.10 kg/hm2,K2O 534.90 kg/hm2.Under this condition,the highest yield was 18 612.75 kg/hm2.Fertilizer application for the optimal economic benefit was N 420.60 kg/hm2,P2O5 70.50 kg/hm2,K2O 492.15 kg/hm2.Under this condition,the optimal yield was 18 579.00 kg/hm2.关键词
