The effection of sumash-ridging cultivation technology on the growth and yield of corn in Yellow River irrigation district of Ningxia

为了探索提高宁夏引黄灌区玉米产量的新型农业耕作措施,以玉米先正达408为研究对象,分析粉垄栽培技术对玉米生长和产量的影响.结果表明:粉垄可降低土壤容积质量,促进玉米根系生长发育,与传统耕作方式相比根长增加17cm,产量提高12.1%.

In order to develop the new agricultural measures with which improving the corn yields in Yellow River irrigation district of Ningxia.This paper taken Xianzhengda408 as the study object to analogized the sumash-ridging effect on the corn growth and yield.The study results shown that the sumash-ridging can break plow pan,reduce the soil bulk density.The sumash-ridging can increasd the main root length and corn yield by 17 cm and 12.1%,respectively,than that of the conventional tillage.
