摘要
为解决黄土高原丘陵旱地小麦缺水的问题,在晋南万荣、晋中灵石连续两年的旱地条件下进行麦草覆盖与耕作试验,结果表明,在干旱条件下,所有不同生育时期的覆盖与对照相比都有十分明显的增产效果,而且具有调温保墒,提高水分生产效率和水分利用效率的作用。同时研究表明采用伏深耕施肥+全程覆盖的方法是抗旱高产、节能省工的捷径。通过试验形成了一套休闲期麦草覆盖封闭耕作栽培的旱作技术体系。
In order to resolve the lack of water existing in the dry lands of the loess plateau hills in southern part of Shanxi province (Wanrong county) and in middle part of Shanxi province (Lingshi country), the straw covering technique and tillage comparison testing has been carried out on the dry condition in the successive 2 years.The result suggests that the technique of straw covering has more obvious impact on increasing the productivity in the different stage than CK.It also can shift the mild preservation of soil moisture,increase the water content production efficiency and its use efficiently.Moreover,the research shows that the adoption of deep ploughing fertilizers and the whole course covering waysis a shortcut to fight against drought,gain high production,save energy and save manpower.Therefore, a cultivated technique system of closed straw covering in leisure stage is developed in this paper.
