近年来,水肥一体化在我国有了较快发展,水溶肥得到了大力推广,但目前大多地方的施用方式相对来说还比较粗放,一般是将肥料溶解于水,通过人工淋施、浇施或冲施入田;而真正实现水肥一体化的模式应该是将肥料溶解后,通过灌溉管道输送到田间,如喷灌、微喷灌、滴灌等。据了解,这一技术模式开始于上世纪90年代末,最早应用于大棚蔬菜滴灌及新疆棉花膜下滴灌,目前应用面积超过2500万
In recent years, the integration of water and fertilizer in our country has developed rapidly, water-soluble fertilizer has been vigorously promoted, but at the moment most of the places where the application is still relatively extensive, the fertilizer is generally dissolved in water, by artificial shower, pouring Or rushed into the field; and the real integration of water and fertilizer should be the mode of dissolution of fertilizer, irrigation pipelines transported to the field, such as sprinkler irrigation, micro-irrigation, drip irrigation. It is understood that this technology model began in the late 90s of last century, the earliest used in greenhouse plastic drip irrigation and Xinjiang cotton drip irrigation, the current application area of more than 25 million
