商洛南五味子施肥配方技术研究

Fertilization on Schisandra sphenanthera in Shangluo

在商洛南五味子药源基地土壤肥力检测评价的基础上,按照肥力分级指标划分出商洛不同种植区的地力分区。依据供试地南五味子的肥料效应田间试验结果,对各分区的N、P、K含量进行调整,拟定不同肥力分区的南五味子施肥配方及缓释配方技术方案,制作指导施肥简易卡片。本研究得到的有关商洛南五味子的缓释专用复合肥配方为N-P_2O_5-K_2O+硼、锰、钼+双氰胺/氢醌,能够作为研究开发适应于商洛地区不同种植区域肥力水平的南五味子专用肥及生产中南五味子施肥技术的参考依据。

Based on the analysis and evaluation of soil fertility in the planting base of Schisandra sphenanthera in Shangluo, the soil fertility was classified according to the classification indexes. Based on the fertilizer effect test of S. sphenanthera, the content of N, P, and K in each subarea was modulated, and the formula of fertilizer and slow-release fertilizer for different fertility subdivisions were formulated. Meanwhile, simple fertilization instructioncardswerecreated.Thespecializedlow-releasefertilizerformula:N-P2 O5-K2 O+B,Mn,Mo+DCD/HQ were obtained, which could be used as a technical reference for developing special fertilizer for S. sphenanthera planting areas with different soil fertilities in Shangluo. The study can provide certain references for the fertilization on S. sphenanthera in future production and practice.
