本研究以孟加拉国Ranisankail系列土壤为研究对象，研究了施用石灰对麦田土壤化学性质和小麦产量的影响。以白云石(CaCO3.MgCO3)为原料，对其进行了8种处理。记录小麦收获时的产量和产量构成因素，分析籽粒和秸秆中磷、硫、钙和镁的含量。对采后土壤pH、有效磷、钙、镁进行了分析。施用不同比例的石灰逐渐提高了土壤pH，提高了土壤中磷、钙、镁的有效性。采后土壤pH值与土壤有效钙、镁含量呈正相关。小麦籽粒产量与收获后土壤pH、有效磷、钙、镁含量呈正相关。施用石灰显著影响分蘖数、颖花穗数、粒数穗数、籽粒产量和秸秆产量。T5 (2.0 t石灰hm - 2)处理的籽粒产量为4659 kg hm -1，与T6、T7和T8处理相同，但高于T1、T2、T3和T4处理。石灰显著提高了小麦籽粒中S和Mg的含量，但对P和Ca的含量没有影响。 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.
