摘要: 作物产品中的钙含量是人类钙营养元素的重要来源,施钙能够提高植物性食品中的含钙量,从而有利于人类健康。若植物新根生长受阻或蒸腾作用减小,作物中钙的含量急剧降低,这样将影响作物的正常生长发育。通过对作物进行根外喷施钙肥,能够快速有效的补充植物对钙元素的需要。本试验通过在苹果的开花期、结果期以及膨大期连续三次叶面喷施不同含量的钙肥,测出喷施含钙量为160g/L钙肥的苹果树的每公顷产量较对照清水的增产5666.6kg,增产率达14.4%,并且方差分析达极显著水平;在喷施含钙量为120g/L的钙肥的苹果树的每公顷产量较对照清水的增产4888.8kg,增产率达12.4%,并且方差分析达显著水平。

Abstract: In the crops product, calcium content is the important origin of human calcium nutritive elements. Calcium fertilization can enhance the calcium quantity in vegetative food, thus it would do favor to the health of the human being. If the new root growth is blocked or the transpiration reduces, and the calcium content in the crops suddenly reduces, it will affect the regular growing development of the crops. Through spurting Calcium fertilizer on the out root of the crops, it can have a fast effective supplement of the calcium need to the plant. This experiment tests the following conclusion through three foliage sprays continuously with different calcium content during blossom period, fruiting period and inflated period: comparing the apple output per hectare with spurting clear water, if spurting Calcium fertilizer with 160g/L, it can increase production 5666.6kg/hec, the rate is 14.4% and the analysis of variance is shown extremely significant level. If with 120g/L, it can increase 4888.8kg/hec, the rate is 12.4%, and the analysis of variance is shown significant level.
