1988年,我场引进了由河北农业大学基础部研制的多元络合复合微肥,已在我场不同土类、不同作物上施用,面积达5.3万亩,增产增收。现总结如下。一、络合复合微肥的优良特性络合复合微肥是多元有机微肥。内含硼、钼、锌、铜、铁、钙等多种微量元素,呈螯合物形式存在。它与单独金属离子的无机混合微肥相比,能减少土壤对它的固定和雨水的淋失作用。特点是: 1.易溶于水、无沉淀、无结晶,易被植物吸收。适于大面积飞机作业和机械喷施。 2.可与目前常用的杀菌、杀虫、灭草剂混用。
In 1988, I introduced the multi-complex compound fertilizer developed by the Department of Basic Agriculture of Hebei Agricultural University. It has been applied on different soil types and different crops in our field with an area of 53,000 mu and increased production and income. Now summarized as follows. First, the complex characteristics of complex micronutrient Compound complex micronutrient is a multi-element organic fertilizer. Containing boron, molybdenum, zinc, copper, iron, calcium and other trace elements, the presence of chelate forms. It is compared with the inorganic mixed micronutrient alone metal ions, can reduce the soil to its fixing and rain leaching. Characteristics are: 1. Soluble in water, no precipitation, no crystallization, easily absorbed by plants. Suitable for large-scale aircraft operations and mechanical spraying. 2. Can be used with the current sterilization, insecticide, herbicide mixture.
