摘要
在最具有典型性和代表性的松嫩平原西部苏打盐碱土区(大安市)高梁田上,进行了不同深松耕法对苏打盐碱化旱田土壤容重、作物产量及相关性状的影响研究,结果表明:深松措施能够有效降低苏打盐碱化土壤容重,促进作物根系发育,显著提高作物(高梁)产量;深松措施可作为土壤紧实、容重较高的苏打盐碱土改良与高效利用的有效耕作方式加以实施。深松方法以效果极为显著且具有可操作性的处理1(垄沟深松40cm,中耕深松30cm)为佳,实施程序为原垄垄沟深松40cm—→撒施底肥—→破开原垄合成新垄—→中耕时垄沟深松30cm。
In the classic and representative area of soda-alkaline land in westen Songneng Plain, an experiment was conducted to investigate the effect of different subsoil tillage models on soil bulk density, crop yield and related components. The results showed that subsoil tillage reduced soil bulk density, improved root development and increased crop （sorghum） yield effectively. Subsoil tillage was an effective way to improve and utilize the compact soda-alkaline land with high soil bulk density. The treatment 1 （40 cm subsoil tillage in furrow and 30 cm subsoil tillage in mid-term cultivation） was maneuverable and greatly commended. The process of application was ： 40 cm subsoil tillage in original furrow→apply base fertilizer→transform old ridge to new one→30 cm subsoil tillage in furrow in mid-term cultivation.
