内容 A factorial experiment using forced tulips in a greenhouse, in combinations of 3 spacings (8, 10 and 12cm square plantings), 3 soil fertility levels and the use of bulbs grown on sandy loam soil and coastal sand dunes in preceding generation, was made to determine their effects on the quality and yield of tulip cut flowers. The results obtained were the following: 1. The closer spacings in tulips resulted in higher plant height but little splender growth than that of wider spacings. Contrary to expectation, wider-spaced plants where the competition for water, nutrients and light was less did not grow luxuriantly compared to closer spaced plants. 2. After-effect of bulb growing conditions in previous generation (soil texture in this experiment) was clearly observed as regards growth and flowering (bloom quality and yields) of forced tulips. Although growth of plants from sandy loam soil-grown bulbs was superior to the bulbs from sand dunes, flowering time was delayed by the use of bulbs from sandy loam soil. 3. Large amounts of fertilizer application during forcing in greenhouse had of little practical value since an apparent response to that was not seen. Leaves of plants without nutrition, however, were smaller and paler in color than any other plots. 4. The interactions among 3 factors were found to be highly significant and to be all interdependent.
