    摘要:

    黄土地区在六十年代发现苹果缺锌而发生小叶病,七十年代后期又发现玉米缺锌而发生白苗病,近年来,锌肥施用面积逐年扩大,大多数地块施用锌肥肥效明显,但有些地块肥效并不明显.本文拟就土壤中锌的含量与分布、锌肥施用效果及其有效施用条件等问题进行试验研究,为经济合理施用锌肥提供科学依据.

    Abstract:

    1.In loess region,the average content of total Zn in soil is close to that of loessal parent material,but lower than that of the country and higher than that of the world.2.The relationship between the soil texture and Zn content is quite clear,the coarser the soil texture,the lower the content of Zn in soil.The content of available Zn in soil is positively correlated with the content of organic matter and negatively correlated with the content of CaCO3 in soil.In this region,the content of organic matter is lower and the content of CaCO3 is higher.Consequently,the soil deficient in Zn is widely distributed.and it is about more than 50% of area of this region.In addition to application of Zn fer tilizer,such measures as application of organic fertilizer,green manure,afforestation and sowing grass,sewerage irrigation,application of a great quantity of Mn fetilizer,etc.may increase the content of soil available Zn.
