摘要

本文研究了哈密盆地土壤中锌的含量及其分布.土壤中全锌含量范围为30.6～118ppm

均值77.11ppm.有效态锌含量0.1～1.14ppm

均值0.407ppm

其中低于临界值0.5ppm 的样点数为73.4%.有效态锌含量与土壤质地、有机质含量呈正相关.土壤有效态锌在剖面中表层高于下层

差异明显.在缺锌土壤中施用锌肥

小麦增产3.7～22.7%

葡萄增产31.1%.

Abstract

The total Zn contents in soils in the Hami Basin of Xinjiang range from 30.5～118ppm.The mean value of total Zn is 77.11ppm

and it is lower than thatof mean valus (100ppm) of the whole country.The effective Zn contents insoils are 0.1～1.14ppm

and the mean is 0.407ppm.If we take 0.5ppm as acritical value of lacking Zn in the soil

the sampling numbers of less than 0.5ppmaccounts for 73.5% of the total sampling number

The content of effect Zn bearpositive relationship with the content of organic matter and the soil texture.Thecontent of effect Zn in the soil profile are higher in the surface layer than in thelower layer.The yields of wheat and grape in Zn-lacking soils employed Zn-fertilizer can increase by 3.7～22.7% and 31.1%

respectively.
