本文研究了硼、锰、锌、钼和稀土等微量元素与氮、磷肥复配成颗粒肥 ,施用于甜菜的增产增糖效用。先后试验了 1 6个配方 ,从中筛选出了最佳配方。该配方肥比磷二铵增产1 71～ 2 57公斤 /亩 ,增糖份 0 .6个百分点 ;比不施增产 90 0公斤 /亩左右 ,增加糖份 1 .2～ 2 .2个百分点。对实验数据回归处理 ,得出了施肥量与甜菜产量的回归方程为 Y=2 81 6 + 1 1 .1 8X(单位 :公斤 /亩 )。最佳施肥量为 3 0公斤 /亩。
In this paper, boron, manganese, zinc, molybdenum and rare earth and other trace elements and nitrogen, phosphate fertilizer compounded into fertilizer, applied to the sugar beet yield increase effect. Has tested 16 formulas, from which the best formula was screened. The formula fertilizer than the ammonium diammonium yield 71 ~ 2 57 kg / mu, add sugar 0.6 percentage points; than the yield increase of 90 0 kg / acre, an increase of sugar 1.2 ~ 2.2 percentage points. The regression equation of the experimental data was obtained. The regression equation of fertilization amount and sugar beet yield was Y = 2 81 6 + 1 1 .1 8X (unit: kg / mu). The best fertilizer is 30 kg / mu.
