金正大蔬菜专用控释肥是山东金正大生态工程股份有限公司针对蔬菜需肥规律研制而成的最新高科技产品。肥料释放的速率与蔬菜吸收养分的规律相吻合,极大限度地提高了肥料的利用率。主要特点一是提高了肥料利用率。为防止供肥过剩,肥料养分采用缓慢释放的形式,改变了普通速溶肥料养分供应过于集中的特点,减少了营养元素的损失;与普通化肥和复合肥相比,控释肥的养分释放曲线与蔬菜的需求变化曲线更为接近,即利用率更高,因而对 Kim Jung-controlled vegetables for fertilizer is controlled by Shandong Jinzheng Tai Ecological Engineering Co., Ltd. developed for fertilizer law of vegetables from the latest high-tech products. Fertilizer release rate and nutrient absorption of vegetables consistent law, to maximize the utilization of fertilizer. The main feature is to improve fertilizer utilization. In order to prevent over-supply of fertilizer, the nutrient of the fertilizer is in the form of slow release, which changes the feature of over-concentration of the nutrient supply of instant instant fertilizer and reduces the loss of nutrient elements. Compared with common chemical fertilizers and compound fertilizers, the nutrient release curve of controlled- Vegetable demand curve is more close, that is, higher utilization, and therefore right
