多年来,笔者冬天利用取暖设备将蛋壳烘干,夏天在太阳下将蛋壳晒干,而后捣碎如小米粒大小,用瓶收集起来。春秋季翻盆换土或新购花卉上盆时,在培养土中掺入2%～5%的蛋壳粉(喜酸性的杜鹃、米兰等少加,喜钙质土的石榴、南天竺等多加)。不翻盆换土的年份于春秋季沿花盆边用小铲挖一圈深2～3厘米的沟,然后根据盆的大小将2～7克蛋壳粉撒在沟内与土拌和,最后用土盖上。实践证明,施用蛋壳粉的花卉长得比过去好,尤以开花结果的花卉效果明显,如石榴花色更红艳,果实多而大,冬季叶落而果犹存。蛋壳粉之所以能起到育花促长的作用,主要在于:一.掺入的蛋壳粉能改良土壤的物理性状,使之更疏松透气,排水良好,有利于根的生长,根壮则花繁叶茂。同时,土质疏松透气好,还有利于土中微生物的生长活动,它们会不断地将土中的有机质分解为花卉所能吸收的养分。
Over the years, the author used the heating equipment to dry the eggshell in winter, dried the eggshell in the sun in summer, and then mashed the size of the rice grains and collected them in bottles. Spring and autumn turning pots or newly bought flowers on the pot, the cultivation of soil mixed with 2% to 5% of the eggshell powder (like acidic cuckoo, Milan and other add less, hi calcareous soil pomegranate, Nandina Zhu et al Add more). Do not turn pots to replace the soil in the spring and autumn along the pot edge of a small circle with a shovel deep 2 ~ 3 cm ditch, and then according to the size of the pot will be 2 to 7 grams of eggshell powder sprinkled in the ditch and soil mixing, and finally Cover with soil. Practice has proved that the use of eggshell powder flowers grow better than in the past, especially the flowering effect of flowers obvious, such as pomegranate color more glorious, more and more fruit, winter leaves still remain. The reason why the egg shell powder can play a role in promoting flower growth, mainly lies in: 1. Incorporation of eggshell powder can improve the physical properties of the soil, make it more loose and breathable, well drained, is conducive to root growth, root The flower leafy. At the same time, loose soil and good air permeability, but also conducive to soil microbial growth activities, they will continue to break down the organic matter in the soil nutrients can be absorbed by flowers.
