摘要
对豫麦5 0号和郑麦975两个小麦品种进行起垄栽培,研究起垄栽培对根系发育及土壤特性的影响,结果表明:在根系密集的5～2 0cm耕层,小麦垄作春季耕层温度比平作提高0 .4～5 .0℃,地表土壤温差高于平作2 .0～6 .7℃。同时,垄作栽培可一定程度上改善土壤理化性质,降低土壤容重,增加土壤总孔隙度,促进小麦根系发育,增强发根潜能。
Studies with two wheat cultivars,Yumai 50 and Zhengmai 975,planted under two different planting system:bed planting and flat planting showed that , bed planting can increase the temperature about 0.4-5.0℃ in spring compared with flat planting in the 5-20 cm plough layer,and increase variation temperature about 2.0-6.7 ℃ in superficial soil.It can also improve the soil physicochemical characters,reduce the bulk density,improve the soil porosity,promote the wheat root growth and increase the wheat yield significantly.
