不同耕翻方式对盐碱地玉米生长及产量的影响

Effects of Different Tillage Methods on Growth and Yield of Maize in Saline-alkali Soil

为了探索适宜盐碱地区玉米生产的耕翻方式,以郑单958为试材,采取免耕(CK)、深翻+旋耕、深松+旋耕、旋耕4种耕翻方式播种玉米,研究了不同耕翻方式对土壤含水量、土壤紧实度和玉米产量的影响。结果表明:深松+旋耕方式的松土保墒和玉米增产效果最好,深翻+旋耕效果次之。

In order to explore the suitable tillage method for production of maize in saline-alkali soil, using Zhengdan 958 as test material,and four kinds of tillage methods including no-tillage（ CK）,deep plowing ＋ rotary tillage,deep loosening ＋ rotary tillage,rotary tillage,the effects of different tillage methods on soil moisture,soil compaction and yield of maize were studied.The results showed that the effects of deep loosening ＋ rotary tillage method on loosen the soil,preserving soil moisture and increasing production were best,followed by the method of deep plowing ＋ rotary tillage.
