摘　　要：根据依安县土壤基础肥力和甜菜产量形成需肥规律，研究出两个甜菜高产高糖施肥配方：（1）45t／hm2的施肥配方为N123P104K92，每公顷施尿素180kg、磷酸二铵225kg、硫酸钾180kg，甜菜单产为51．45t／hm2，含糖率为18．06％；（2）60t／hm2的施肥配方为N152P124K115，每公顷施尿素225kg、磷酸二铵270kg、硫酸钾217．5kg，甜菜单产为63．9t／hm2，舍糖率为18．29％。两个施肥配方经生产示范验证均达到计划产量指标。Based on the basis fertility of soil and the formed law of sugar beet yield in Yian county, we got two fertilizer formulas of high yield and high sugar： （ 1 ）the fertilizer formula for sugar beet yield 45t/hm2 was by fertilizer N123P104K92,which fertilized the urea 180kg and the diammonium phosphate 225kg and the potassium sul- phate 180kg, as well sugar beet yield got 51.45 t/hm2, sugar rate was 18.06% ; （2）the fertilizer formula for sugar beet yield 60t/hm2 was by fertilizer N152P124K115, which fertilized the urea 225kg and the diammonium phos- phate 270kg and the potassium sulphate 217.5kg, as well sugar beet yield got 63.9t/hm2 and the sugar rate was 18.29%. Two fertilizer formulas came up to the plan yield indicators through the production demonstrated verifi-
