测土施肥与肥料创新

Innovation of fertilization, applying fertilizers according to soil analysis

测土施肥是一个系统工程,肥料创新是其中非常重要的环节。掺混型肥料成为适应测土施肥推广的肥料产品,为业界所关注。我国人多地少,复种指数高,新型缓控释肥料与我国国情相结合的就是“一茬作物(只施)一次肥”。同时,测土施肥还需要施肥机械与施肥技术的创新,实现平衡施肥与肥料深施。涂层缓释一次肥以其全新的缓释理念和养分管理模式,成为适应测土施肥的肥料新产品。

Applying suitable amount fertilizer under different soil fertility is a systematic engineering. Innovation in fertilizer can be a helpful tool in the implementation of the systematic engineering. Blending bulk fertilizers, a product suitable for application under different soil fertility, has widely attracted industry concem. In China, intensive labour input to farmland results in high multiple cropping index. Many times of application of fertilizers are necessary. The development of slow release fertilizer makes it possible to apply fertilizer once in each crop. The application of new slow release fertilizer also needs the help of machine and new techniques for fertilization application. Application of coating techniques in slow release fertilizer brings out the new type of fertilizer suitable for different soil fertility condition
