钙在植株体内的运转 田间花生缺钙通常产生秕果,有关秕果原因的研究着重于两方面:一是花生地下结实的位置,二是钙在花生植株体内移动受限制的特性。花生吸收钙的方式为被动吸收,即钙的吸收量取决于土壤溶液中钙的浓度和花生对水分的吸收量。钙离子在植株体内几乎都通过木质部运输,因而钙只能随蒸腾流在木质部中自下而上运输,而从叶片通过韧皮部向下运输的钙几乎等于零。
Calcium in plant plants in the field Calcium deficiency in peanut field usually produce mango, the research on the causes of mango focuses on two aspects: First, peanut underground solid location, and second, calcium movement in peanut plants restricted characteristics. The way that the peanut absorbs calcium is passive absorption, that is, the amount of calcium absorbed depends on the concentration of calcium in the soil solution and the amount of water absorbed by the peanut. Calcium ions are transported almost entirely in the plant body through the xylem, so calcium can only be translocated in the xylem with transpiration flow and calcium transported from the leaf down through the phloem is almost equal to zero.
