摘要
研究了两种不同类型的土壤调理剂对大蒜田土壤理化性质和大蒜产量的影响。结果表明:两种调理剂均能降低土壤容重,提高土壤孔隙度。两种调理剂对速效养分的影响则有所不同:蒙脱石提高了土壤速效氮和钾含量,降低了土壤速效磷含量,麦饭石对土壤速效氮和磷影响不大,对土壤速效钾影响表现为先升高后降低。蒙脱石、麦饭石均能提高土壤有机质,对大蒜产量亦有所提高。综合比较两种土壤调理剂,应用蒙脱石效果较好。
The effects of two kinds of representative soil conditioners on soil physico- chemical proper- ties and yield of garlic were studied in this paper. The results showed that the two conditioners could reduce the soil bulk density but improve the soil porosity. There were some differences between the two soil condition- ers on soil available nutrients. The montmorillonite conditioner increased the content of available N and K, but reduced the content of available P. The medical stone had no obvious impact on available N and P, but made the soil available K increased firstly and then decreased. Both of them could increase the soil organic matter and garlic yield. Comprehensively considering the effect, the montmorillonite conditioner was better.
