摘要

Hardwood cuttings of fig cv. Masui Dauphine were grown in nutrient solutions with electrical conductivities (EC) of 1.8 or 2.4, or one in which the EC was reduced from 2.4 to 0.6 dS/m in mid-season. The non-circulating closed culture system dependedon the capillary action of rockwool and irrigation, and the experiment was designed for annual double cropping. For the first planting, cuttings were made on 10 January, and the rooted cuttings were transplanted on 24 February. The EC of the 1.8 and 2.4dS/m solutions increased gradually to 9.5 and 10.1 dS/m, respectively, until 30 June, when the first crop was harvested. The amount of solution absorbed by the plants in the EC 2.4 dS/m treatment was lower than that absorbed in the 1.8 dS/m solution. When the EC decreased from 2.4 to 0.6 dS/m, the amount of solution absorbed increased from May to harvest. The leaf area was smallest in plants which absorbed the least amount of solution. At harvest, the early fruits from the EC 1.8 and 0.6 dS/m solutionswere larger and degree CBrix of the juice was lower than for fruits from the 2.4 dS/m treatment. When the bearing shoots were cut back on 30 June, shoot growth was renewed after 12 days. The number of fruits set in the second crop was lower below the 10th nodecompared with the first crop. Harvest of the second crop started on 16 November and continued until 28 December. The leaf area at the highest node, fruit size and degree CBrix of the juice were lower than in the first crop. Many fruits cracked in the plot where EC was decreased from 2.4 dS/m to 0.3 dS/m from September to December.
