温室番茄植物（Lycopersicon esculentum Mill.栽培品种“Caruso”）在连续种植系统中生长，在成熟植物之间间作幼小植物。 4个移栽期分别为7月24日、11月2日、2月5日和4月19日。 这些植物被种植在岩棉板上，并在V形系统中进行训练。 处理是两个水平的光合光子通量密度（PPFD），100和150 μ mol m-2 s-1，由400-W的高压钠灯（HPS）灯在16小时的光周期从9月至5月，和三个植物密度：（a）低密度，2.3株m-2的所有四个继承。 最高的累积产量为四个继承（39周采摘）分别为56和72公斤m-2在100和150 μ mol m-2 s-1，分别为可变的种植密度。 两种光照处理的产量在高密度和变密度下分别比低密度高14%和34%。 较高的PPFD处理提高了10，16和14%，分别为低，可变和高种植密度采摘的果实总数。 与同步良好的作物，在高密度种植与补充照明100和150 μ mol m-2 s-1，年产量分别为70和84公斤m-2，预测。
Greenhouse tomato plants (Lycopersicon esculentum Mill. cultivar 'Caruso') were grown in a sequential cropping system, intercropping the young plants between the mature plants. The four transplanting dates were 24 July, 2 November, 5 February and 19 April. The plants were cultivated on rockwool slabs and trained in a V-shaped system. The treatments were two levels of photosynthetic photon flux density (PPFD), 100 and 150-mu-mol m-2 s-1, supplied by 400-W high-pressure sodium (HPS) lamps during a 16-h photoperiod from September to May, and three plant densities: (a) low density, 2.3 plants m-2 for all four successions. The highest cumulative yields for the four successions (39 weeks picking) were 56 and 72 kg m-2 at 100 and 150-mu-mol m-2 s-1, respectively, for the variable planting density. Yields were respectively 14 and 34% greater at the high and variable densities than at the low density for the two light treatments. The higher PPFD treatment raised the total number of fruits picked by 10, 16 and 14% for the low, variable and high planting densities, respectively. With well-synchronized crops, at high-density plantings with supplemental lighting of 100 and 150-mu-mol m-2 s-1, annual yields of 70 and 84 kg m-2, respectively, are predicted.
