석회질 및 규산질비료가 칼라의 생육, 절화품질, 줄기 경도 및 무름병 발생에 미치는 영향을 조사한 결과, 석회질비료 처리에서 잎의 생장 및 초장은 기비보
다 엽면살포구에서 더욱 효과적이며, CaCl2 0.1% 처리구가 초장 111.7cm, 엽장 32.7cm, 절화장 118.6cm 로 무처리 73.3cm, 23.8cm 및 79.6cm에 비해 효과적이었다. 석회질 비료가 줄기 경도에 미치는 영향은, 기비보다 엽면살포구에서 더욱 효과적이었으며, 엽면살포 처리중에서도 0.1% 처리구에서 가장 경도가 강했고 세포 및 조직이 규칙적이었다. 규산질비료 처리구에서는 농용규산 50kg· 10a−1 처리구에서 잎의 생장, 생체중, 경도 및 절화품질 등 모든 면에서 양호하게 나타났다. 석회 및 규산질비료 시용과 무름병과의 관계는 엽면살포구보다 기비처리구에서 발병율이 낮았으나 두 처리구 모두 대조구보다는 다발하여 무름병과 상관관계는 없는 것으로 생각되었다. 칼라의 생육 및 개화에는 석회질비료가 규산질비료보다 효과적이었고 적정 농도는 0.1%였다.

Objective of this research was to determine the influence of foliar application of CaCl2 or K2Si2O5 and soil application of CaCO3 or SiO2 on growth and cut flower quality of Zantedeschia aethiopica ‘Wedding March’. To achieve this, CaCl2 or K2Si2O5 were applied at six leaf stage with the concentration of 0.05, 0.1 and 0.2% and CaCO3 or SiO2 were applied as basal fertilization with the amount of 100, 200, 400kg per 10a or 50, 100, 200, 400kg per 10a respectively. Plant material was used Zantedeschia aethiopica ‘Wedding March’. Among calcium chloride(CaCl2) and calcium carbonate(CaCO3), calcium chloride foliar application was more effective than calcium carbonate with basal fertilization to growth of common calla ‘Wedding March’. In the
0.1% solution foliar application of calcium chloride, plant height, leaf length and length of cut-flower was more longer than control. Length of leaf petiole was more longer and leaf fresh weight was more heavier than control.
The degree of petiole hardness was more effective in the 0.1% solution calcium chloride foliar application than any other treatment. In the silicate fertilization treatment, plant height of 50kg per 10a treatment was most
highest as 73.9cm. Also its length of leaf petiole and leaf fresh weight was more effective than any other treatment. The hardness of petiole was better in the 50kg per 10a silicate fertilizer treatment. The cell shape of leaf petiole was round and tissue was regular in the treatment of 0.1% calcium chloride and 50kg per 10a silicate fertilizer but the cell of control was irregular round type. Macro element content of calcium was more amount in the treatment of silicate 50kg per 10a basal fertilization. The infected ratio of Erwinia was no
relation with lime and silicate fertilizer treatment. Lime fertilizer treatment is effective for growth and flowering of Calla than silicate fertilizer and the suitable concentration was 0.1%.
