大豆专用复肥对轮作、连作大豆营养生长影响的研究

Study of the Effect of Soybean Specificly Complex Fertilizer on Nutrition Grouth of Soybean in Different Cropping System

摘要:

通过盆栽试验、田间试验及室内分析相结合的方法，研究施用大豆专用复肥对轮作、连作大豆营养生长的影响。结果表明，施用复肥能提高轮作、连作大豆植株硝酸还原酶活性，降低吲哚乙酸氧化酶活性，提高大豆植株的相对生长率和最大生长率，进而提高了产量。上述结果说明，复肥能促进轮作、连作大豆的营养生长，为大豆的丰产丰收提供物质基础。

Abstract:

Effects of applying soybean specificly complex fertilizer on different soybean croppings was stuclied by pot experiments, field experiments and chemical analysis indoor. The results show:Applying the complex fertilizer can increase the nitrate reductase cutirity and decrease the indolocacetic acid oxidasc cutirity, raise relative and the largest growth rate of soybean and yield. The complex fertilizer can promote soybean’s nutrition growth on rotation and continuous system.
