我国华北地区是极度缺水、贫水地区,而农业用水又占较大比重,其中,小麦为高耗水农作物,前人在小麦节水方面进行过生物节水、化学节水、农艺节水、工程节水等多种形式的探讨,起到了一定作用,但仍未达到理想效果。2011年石家庄市政府投资400多万元,在石家庄地区18个农业县（市、区）的480.148 hm2麦田、105眼机井进行了小麦微喷水肥一体化技术大面积示范试验。结果表明：该技术具有＂两节＂（节水、节地）、＂两省＂（省工、省时）、＂两增＂（增产、增效）的明显效果,但也有部分麦田减产,且在微喷带带宽、设备安装拆卸、喷水次数、用肥次数、组织形式等方面存在着一些问题。由于石家庄市在华北地区属于首家进行小麦微喷水肥一体化技术大面积多点试验示范区域,许多经验和试验结果可供今后该技术大面积推广借鉴。

North China is seriously lack of water.Agricultural water consumption is the largest,especially wheat.The biological water saving,chemical water saving,agronomic water saving,and engineering water saving have been used in wheat production,while the ideal effect was not got instantly.More than 4 million yuans was invested by Shijiazhuang City Government,the experiment and demonstration of integrative water and fertilizer planting technology with salient irrigation of wheat were carried out in 18 counties.The results showed that the technology had obvious effects in saving water,land,labor and time,and increasing yield and effciency,while it resuts in yield reduction in some regions.There were some problems in wide salient irrigation belt,installing and dismantling equipments,irrigation times,fertilization times and organization forms and so on.The technology was firstly tested and demonstrated in multi points in large areas of Shijiazhuang,and many useful practices and results could be referred for other cities.
