我团在1980年液氨直接施肥试验的基础上,1983年作为新疆液氨施肥技术推广点之一,扩大了推广面积。今年在春麦、玉米、水稻、油葵、冬白菜以及84年冬麦等作物栽培中采用液氨施肥的面积已达1.5万亩,占我团当年种植面积的15％。试验推广证明:这项新技术在我团场的多年实践中是成功的,取得了明显的经济效果。 一、液氨施肥成功的原因 第一,它是含氮量最高的一种N素化肥。液氨含氮量高达82.3％,相当于碳铵的4.9
On the basis of the experiment of liquid ammonia fertilization in 1980, I regrouped the promotion area as one of the popularization points of liquid ammonia fertilizer technology in Xinjiang in 1983. This year in the spring wheat, corn, rice, oil sunflower, winter cabbage and 84 years of winter wheat and other crop cultivation using liquid ammonia fertilization area has reached 15,000 mu, accounting for 15% of the acreage that year I group. Test promotion proved that: This new technology has been successful in my field many years of practice and achieved obvious economic results. First, the reasons for the success of liquid ammonia fertilization First, it is the highest nitrogen content of a N-fertilizer. Liquid ammonia nitrogen content as high as 82.3%, equivalent to 4.9 ammonium bicarbonate
