１引言 叶面喷施微肥不受土壤性质的影响，可以直接通过叶面而被吸收利用，除提高作物产量外，也提高了人畜必需的全价营养物质，改善了其产品品质。 黑龙江省安达地区土壤为典型的盐碱土，其ｐＨ值达到７．８～８．０左右，所施用的微量元素被固定或降低利用率，而达不到预期
1 Introduction Foliar application of trace fertilizers is not affected by the nature of the soil, can be absorbed directly through the use of foliar surface, in addition to improving crop yields, but also improve the human and animal necessary full-price nutrients to improve their product quality. The soil in the Anda area of Heilongjiang Province is a typical saline-alkali soil with a pH value of about 7.8-8.0. The applied trace elements are fixed or reduce the utilization rate, which can not meet expectations
