水肥一体化是将肥料溶解在水中,借助管道灌溉系统,灌溉与施肥同时进行,适时适量地满足作物对水分和养分的需求,实现水肥一体化管理和高效利用的节水农业技术,多年、多地、多作物推广应用效果明显。增产增收增效内蒙古、吉林、黑龙江等地应用膜下滴灌水肥一体化技术,玉米亩增产200~300千克,马铃薯亩增产1500千克。河北、山东、河南等地应用微喷水肥一体化技术,冬小麦亩增产100千克,玉米亩增产150千克,马铃薯亩增产1000千克,增产幅度在
Water and fertilizer integration is to dissolve fertilizer in water, with pipeline irrigation system, irrigation and fertilization at the same time, timely and appropriate to meet the crop’s moisture and nutrient needs, to achieve integrated management of water and fertilizer and efficient use of water-saving agricultural technology, for many years Land, multi-crop promotion and application of obvious results. Increase production and increase income and efficiency Inner Mongolia, Jilin, Heilongjiang and other places with the application of drip irrigation technology integration of water, corn acres increased 200 to 300 kg, 1500 acres of potato acre yield. Hebei, Shandong, Henan and other places integrated application of micro-spray fertilizer, winter wheat acres increased 100 kg, 150 acres of corn acre yield, potato acres increased yield 1000 kg, the rate of increase in
