新疆生产建设兵团绿洲灌溉区保护性耕作对比试验

Comparison test on conservation tillage technology of oasis irrigation district in Xinjiang production and construction crops

通过2010--2012年在新疆绿洲灌溉区的定点试验，监测了保护性耕作和传统耕作两种不同处理方式小麦、油菜轮作的试验田情况，采集土壤含水率、土壤有机质含量、紧实度、作物生育期、病虫害发生情况等数据进行对比分析。结果表明：与传统耕作的试验田相比，长期深翻覆盖免耕作业处理试验田土壤含水率和有机质含量增加，紧实度降低，作物生育期延长5～10d，杂草数量增加，病虫害减少。

Based on long-term site-specific trials from 2010 to 2012 of oasis irrigation strict of Xinjiang, monitored experimental fields of two experimental plots of wheat, cole crop rotation processed by conservation tillage and traditional cultivation. The dates about soil water content,organic substances content in soil, soil compaction, crop stages, plant diseases and insect pests and etc were collected. The results showed that compared with the traditional cultivated plots, the fields processed with sub soiling tillage with mulching have higher quantity of soil water content and organic substances content in soil, low dates of soil compaction, crop growing period can be prolonged 5 to 10 days, quantity of weeds was increase, pests and diseases were reduced.
