摘要:
旱地农田长期轮作有较好的培肥改土作用，经过17年轮作，各轮作系统土壤养分状况得到明显的改善。在轮作系统中引入豆科作物后，土壤有机质、全氮、碱解氮含量显着增加，但全磷和有效磷却有所降低；当施入磷肥和有机肥后，全磷和有效磷含量也有所增加，所以豆科作物培肥应配施磷肥和有机肥。土壤养分状况因作物茬口不同而出现明显差异，豆科作物茬口的土壤养分有显着的累加效应。
Abstract:
After 17 years fixed position of continuous applying fertilizer in rotation, the results show that Crop rotation in arid land could improve soil fertility and increase soil nutrients.Leguminous can increase the contents of soil organic matter, total N and available N, but total P and available P decreased.Total P and available P will increase only when organic fertilizer or phosphorus is applied.So it is suggested that in the course of leguminous plant fertilizing soil, phosphorus and organic fertilizer should be added.Different soil fertility was observed due to the different crops.
