从给土壤施肥到给作物根区施肥,我国农民应该如何正确施用水溶肥、达到水肥利用效率最大化。陈清介绍说,微灌施肥是水肥管理的新理念,微灌的可控性意味着施肥变得简单可控。“通过微灌系统进行施肥,相当于‘用勺喂’作物,给作物打‘点滴’,能够准确地控制施肥的时间、次数、养分品种和量。为了有效防止灌水器堵塞,按照最小灌水器出口径0.5mm的1/10计算,滤除的水不溶物颗粒应不大于0.05mm。此外,滴灌施肥的操
From fertilizing the soil to fertilizing the crop root zone, how to properly apply water-soluble fertilizer to farmers in China so as to maximize water and fertilizer utilization efficiency. Chen Qing said that micro-irrigation fertilization is a new concept of water and fertilizer management, micro-irrigation control means that the fertilization becomes simple and controllable. ”Through the micro-irrigation system for fertilizing, the equivalent of ’spoon feeding’ crops, the crop hit ’drip’, can accurately control the fertilization time, frequency, nutrient varieties and quantities.In order to effectively prevent the emitter plug, according to the minimum irrigation Outlet diameter 0.5mm 1/10 calculation, the water insoluble particles filtered should not be greater than 0.05mm. In addition, the practice of drip irrigation fertilizers
