大豆专用复混肥对轮作、连作大豆增产机理的研究

Study on the Mechanism of Soybean Special Complex Fertilizer on Increasing Yield of Crop Rotate and Continuous Cropping Soybean

摘要:

采用盆栽试验、田间试验及室内分析相结合的方法,研究了含有沸石、腐殖酸、稀土的大豆专用复混肥对轮作、连作大豆的增产机理。结果表明,施用大豆专用复混肥对轮作、连作大豆具有明显的改土、增加肥效、抗逆、提高光合效率和促进大豆生长的作用,最终表现出明显的增产效果。大豆专用复混肥的综合施用效果以连作大豆好于轮作大豆。

Abstract:

The mechanism of soybean specialized complex fertilizer contains boiling stone, humic acids, rare earth on increasing yield of rotation and continuous cropping soybean was studied in plot-experiment, field-experment, and indoors analysis methods. The results showed that the soybean specialized complex fertilizer can distinctly improving the soil, increasing its fertilizer effect and greatly inhanced it’s photosynthetic efficiency and improving soybean’s growth. The final outcome indicated it increased the yield of rotation and continuous cropping soybean. The synthetical effect of soybean specialized complex fertilizer on continuous cropping soybean is higher than that of rotation cropping soybean.
