对于滨海中度盐化土壤,在夏末秋初表层盐分低于其他季节的时期,整地开沟10~15cm播种苜蓿(Med-icagosativaL.)可基本上保证其正常出苗和生长。另外,苜蓿与油菜(BrassicacampestrisL.)混播也可提高苜蓿的保苗率。
For medium saline soil in the coastal area, when the surface salt of the surface layer is lower than that of other seasons in early summer and early autumn, sowing alfalfa (Med-icagosativa L.) at a depth of 10 ~ 15 cm by soil preparation and dredging can basically ensure its normal emergence and growth. In addition, alfalfa and rape mixed (BrassicacampestrisL.) Can also increase the seedling protection rate of alfalfa.
