天安特生态调节剂对南方不同农业土壤结构的影响

Effect of Tianante Ecology Adjustment Agent on Granule Structure and pH of the Agricultural Soil in South China

天安特是一种由碱性物质及一些胶结剂为主要成分的新型生态调节剂。为探讨新开发的生态调节剂天安特对土壤结构及pH值的影响,通过室内模拟和田间实验,进行天安特生态调节剂对南方茶园、果园和菜园土壤结构及pH值影响的研究。结果表明:在田间与室内实验中,天安特对提高3种类型土壤>0.25 mm水稳性团聚体含量和降低土壤结构破坏率均有显著效果,同时可提高茶园、果园、菜园表层土壤pH值,其中以天安特对茶园土的水稳性团聚体结构的改良效果最好,可以在南方地区农业土壤的改良上应用。

The influence of Tianante ecology adjustment agent on granule structure and pH of soil was analyzed in the tea, orchard and vegetable soil. The results indicated that the content of 〉0.25 mm soil aggregate increased with the increment of the Tianante ecology adjustment agent and the ratio of soil structure damage decreased with the Tianante ecology adjustment agent. Tianante ecology adjustment agent has a significant effect on the pH of 0-10 cm soil. The pH value increased with the increment of the Tianante ecology adjustment agent. 〉0.25 mm soil aggregate and the pH value in the tea soil are better than those in the orchard and vegetable soil. Therefore, Tianante was a practicable ecology adjustment agent in agriculture soil in south China.
