前言海伦县碳酸盐草甸土广泛分布在县的西部和西南部通肯河高慢滩以及第一阶地排水不畅的沟谷低地,一般地下水位在2～3米,总面积为98.38万亩。黑土层60～100厘米,质地粘重,整个剖面有碳酸盐反应。在这类土壤上生长的玉米多数发生“紫红苗”、“白苗”和“花叶症”,其主要原因是土壤中有效锌含量不足(0.35～0.7ppM)影响玉米的正常生长和发育,亩产仅300～400斤。试验进行了两年(1981～1982),第一年以小区试验

Preface Helen County carbonate meadow soil is widely distributed in Tongyao high slow beach in the western and southwestern parts of the county as well as in the first-order low-lying drainage valley. The total groundwater level is 2 to 3 meters with a total area of ​​983,800 mu. Black soil layer 60 ~ 100 cm, texture sticky, the entire section of the carbonate reaction. Most of the maize grown on these soils had “purple seedling”, “white seedling” and “mosaic disease”, mainly due to the lack of available zinc in the soil (0.35 ~ 0.7ppM) affecting the normal growth and development of maize, Only 300 to 400 pounds per mu. The trial was conducted for two years (1981-1982), with plot test in the first year
