土壤是陆地上能够生长绿色植物的疏松表层。能够生长绿色植物,说明土壤是一个活的有生命的机体,含有C、H、O、N、P、K等十六种植物必需的营养元素,如何让土壤最大化供应植物生长所需的养分,做好土壤养分管理,是每个土肥人所必须考虑的问题。土壤作为植物生命的载体,由于长期以来人们过度使用、滥用,土壤的理化性质越来越坏,直接影响到植物的正常生长;土壤的生物环境被破坏。“土传病害”越来越多等等一系列症状,证明我们赖以生存的土壤“生病”了。
Soil is a loose surface that grows green plants on land. Can grow green plants, indicating that the soil is a living body, containing nutrients such as C, H, O, N, P, K and other sixteen kinds of essential nutrients, how to make the soil to maximize the supply of nutrients needed for plant growth To do a good job of soil nutrient management, each soil fertilizer must be considered. Soil as a carrier of plant life, due to overuse and abuse by people for a long time, the physical and chemical properties of soil are getting worse and worse, which directly affects the normal growth of plants; the biological environment of soil is destroyed. “Soil-borne disease ” more and more a series of symptoms, to prove that we rely on the soil “sick ”.
