摘要
在河北一年两熟区大田条件下,研究了玉米深松免耕播种对土壤物理性状及玉米生长发育和产量的影响。结果表明：玉米深松免耕播种后,土壤耕层10~40 cm土壤容重较对照田下降了1.77%,0~100 cm土壤含水量较对照高7.53%左右;能够改善玉米根系生长的土壤条件,根系粗壮,促进了夏玉米生长发育,较对照增产10.9%。
The effects of subsoiling and no-till planting on the soil physical properties,the growth,development and yield of maize were studied in field in the areas of two crops a year in Hebei.The results showed that 10-40 cm soil bulk density decreased by 1.77%,and 0-100 cm soil moisture increased by 7.53%.The subsoiling and no-till planting could improve the soil condition of root,promote the growth and development of maize,and increased the yield by 10.9%.
