摘　　要：磷酸二铵施肥深度研究，３年多点试验结果表明：磷酸二铵深施可促进株高、茎粗、节数、荚数、粒数和干物重的增加；磷酸二铵施于种下１０厘米、５厘米、１厘米深分别比种肥同位施增产２２．５％、２３．７％和８．１％，其中有两年试验施于种下１０厘米超过施于种下５厘米深的产量，但产量差异不很显著。为便于生产上大面积应用，认为磷酸二铵施于种下５～１０厘米深为宜。The experimental results of three years in different locations demonstrated that deep spreading of diammonium phosphate could bring about increase of plant height,stem thickness,node nomber,pod nomber,seed nomber and dry matter weight in soybeans.The soybean yields of the fertilizer spreaded under the seeds 10cm,5cm and 1cm depth in creased 22.5%,23.7% and 8.1% respectirely compared with the yield of spreading fertilizer together with seeds.The authors suggested that diammonium phosphate should be spreaded under feeds,5 to 10cm depth in field production.
