近几年,很多传统的农药企业新上马了肥料产品,这些产品多为水溶性和中微量元素肥,属于新型肥料的范畴。此举究竟是企业一时解困的权宜之计,还是能够从根本上改变农资产品结构的创新之举,是一个需要时间来观察、思考和探索的问题。
In recent years, many traditional pesticide companies launched new fertilizer products, these products are mostly water-soluble and trace elements in the fertilizer, a new category of fertilizer. This measure is an expedient measure for enterprises to temporarily solve the problem or is it an innovation that can fundamentally change the structure of agricultural products? It is a question that takes time to observe, think and explore.
