通过对H.11648麻盆栽施用白云石石灰、白云石石粉、氯化钙的试验,探讨它们对剑麻叶片生长量、叶片营养成份含量以及改良土壤酸性的作用。白云石石粉是剑麻增产效益高、改良土壤酸性效果好、成本较低的优良钙肥。
The pot experiment of H.11648 potted dolomite limestone, dolomite stone powder and calcium chloride was carried out to study their effects on the growth of sisal leaves, the nutrient content of leaves and the improvement of soil acidity. Dolomite stone sisal is a high yield increase sisal, acid soil improvement effect is good, lower cost good calcium fertilizer.
