本试验研究对土壤改良剂在灌耕灰漠土和盐化灌耕灰漠土上进行了盆栽和田间微区试验。重点研究改良剂对土壤肥力、农作物生长发育等方面的影响。试验结果表明,合理的使用土壤结构改良剂,不仅可以改良土壤结构增加农作物产量,而且对盐分较重、有机质贫乏、结构不良的土壤,在增加土壤有机质含量,降低耕层土壤盐分含量等方面亦有明显效果。从本试验研究结果看以地表喷施效果最佳。
In this study, soil and improver were potted and field micro-plot experiments on gray desertified soil and salinized gray desert soil. Focus on the improver on soil fertility, crop growth and development and other aspects. The results show that the reasonable use of soil structure improver not only can improve the soil structure and increase crop yield, but also increase soil organic matter content and soil salt content in topsoil with heavy salt content, poor organic matter and poor structure Have obvious effect. From the results of this study to see the best surface spray.
