土壤结构改良剂的改土效果及其使用的研究

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。

Research On The Effect & Application Of Soil Texture Amendment

A Project was conducted with applications of the amendment on the irrigated and cultivated gray yermosoils and the irrigated, cultivated and saltified gray yermosoils in both potted experiments and plotted field t rials.The effect of tne amendment on the soil fertility,crop growth and development was mainly concentrated in this study. The result shows clearly that if the amendment is applied properly, it is not only able to improve soil texture and increase crop yield,but to increase the amount of organic matter contained and decrease salt content in cultivated layers in salty,organic matter lacked,badly textured soils as well.It shows that the best result was gained with the soil surface application of the amendment.
