在大区和微区条件下，研究了白浆土心土培肥对土壤化学性质的改良效果和增产作用；进一步明确心土混层心土混层耕对土壤性结构的影响，研究结果表明，白浆土心土培肥比心土混层耕增产７．３～１０．３％；心土培肥后第一年比未处理对照增产甜菜３２．３％，增产大豆１５．２％；第二年增产大豆１６．９％；对白浆土进行心土培肥，可以达到彻底消除白浆层不良影响和培肥白浆土的目的。
Under the conditions of large area and micro-area, the effect of improving soil chemical properties and increasing yield of white soil soil-core fertilizers were studied. The effect of mixed soil-soil mixed soil layer on soil structure was further clarified , The content of white soil soil core soil fertilization was 7.3 ~ 10.3% higher than that of core soil mixed layer cultivation; the yield of sugar beet was increased by 32.3% and the yield of soybean was 15.2% The second year 16.9% yield soybean; soil calcareous soil white soil, can achieve the complete elimination of the adverse effects of white layer of white soil fertility and fertilizer purposes.
