研究了石灰对孟加拉国Ranisankail土壤化学性质和小麦产量的影响。以白云石(CaCO3.MgCO3)为原料，进行了8种石灰化处理。记录小麦收获时的产量和产量构成，分析籽粒和秸秆的磷、硫、钙、镁含量。对采收后土壤进行了pH、速效磷、钙、镁的分析。施用不同比例的石灰可逐渐提高土壤pH值，增加土壤中磷、钙和镁的有效性。采后土壤pH值与土壤有效钙、镁状态呈正相关。小麦产量与采后土壤pH、速效磷、钙、镁含量呈显著正相关。灌浆对分蘖数、株数^-1、小穗数^-1、粒穗数^-1、籽粒和秸秆产量均有显著影响。处理T5 (2.0 t石灰ha^-1)的产量为4659 kg ha^-1，与T6、T7和T8处理的产量在统计学上相同，但高于T1、T2、T3和T5处理;T4治疗。 Liming markedly increased S and Mg concentrations of wheat grain but the concentrations of P and Ca remained unaffected. Total uptake of P, S, Ca and Mg were increased due to application of lime which was mainly associated with increased wheat yields. The findings showed that liming is beneficial for wheat cultivation in the Ranishankail soil series of Dinajpur. The application of 2.0 t lime ha-1 appears to be optimum for desired soil pH for wheat (>pH 6.0), increased availability of nutrients and ultimately increased wheat yield.
