我们通过整合日本较冷的北部地区的第一（短）和第二（长）作物期，研究了套种对温室番茄果实产量的影响。无论第一季是否套种，适销水果产量都相似，而第二季和总作物期则随着种植日期的提前而增加。因此，在第一季第一批果桁收获后立即播种，对于实现连续收获和在六桁收获结束后大幅提高产量是有效的；此外，第一茬作物期间没有出现茎秆降低的情况。无论第一季是否套种，植物干重也相似。然而，总干重和果实干重随着第二季和总作物期早期套种的增加而增加。 3月份开耕时，商品果产量和全茬干物质总产量比4月份有所增加。所有作物时期的处理中，果实的干物质分配相似。鲜果和干果的总产量与整个作物期间的累积光截获显着相关。因此，3月份开始栽培并在初夏套种时果实产量最高，导致光截留和干物质产量最高。学科：园艺附加关键词：干物质生产、叶面积指数、光利用效率、无土栽培、番茄
We investigated the effects of interplanting on fruit yield in greenhouse-grown tomato by integrating the first (short) and second (long) crop periods in the cooler northern area of Japan. The marketable fruit yield was similar regardless of interplanting in the first crop period, whereas it increased with earlier planting dates in the second and total crop periods. Therefore, planting immediately after the harvest of the first fruit trusses of the first crop period was effective in achieving a continuous harvest and substantial yield improvement upon conclusion of the harvest of six trusses; moreover, there were no incidences of stem lowering in the first crop period. The plant dry weight was also similar regardless of interplanting in the first crop period. However, the total dry weight and fruit dry weight increased with early interplanting in the second and total crop periods. The marketable fruit yield and total dry matter production of the whole crop period increased when cultivation started in March compared with that in April. The dry matter allocation to the fruit was similar among the treatments in all crop periods. The total fresh and dry fruit yields were significantly correlated with the cumulative light interception over the total crop period. Therefore, fruit yield was the highest when cultivation started in March with interplanting in the early-summer resulting in the highest light interception and dry matter production.
