초록
고온기 토마토 재배시 생산현장에서 즉시 적용할 수 있는 효과적인 적엽관리법을 구명하여 수확량과 상품성을 증대하기 위해 본 실험을 수행하였다. 농가에서 관행으로 행해지는 생장점부터 하부로 14개의 잎을 남기고 적엽하는 처리(Leaf-14), 생장점으로부터 하부로 20개의 잎을 남기고 적엽하는 처리(Leaf-20), 유럽에서 관행으로 행해지는 수확 후 화방 하부엽 제거 처리(Harvest), 토마토 잎의 광합성 특성을 적용한 개화 7주 후 화방 하부엽 제거 처리(7-weeks) 등 4개의 처리를 두었다. 적엽처리는 개화속도에는 영향이 미미했으나, 수확속도와 수확량 및 상품성에는 영향이 있는 것으로 조사되었다. 또한 수확속도는 6-7일이 적당하며, 과다한 적엽으로 수확속도가 너무 빠르게 진행되면 총수확량이 감소하므로 적엽하지 않아야 한다. 고온기의 적엽은 Leaf-14보다 Leaf-20이 가장 좋은 방법이며, 7-weeks 처리도 효과적이었으나 적용이 번거로운 단점이 있었다. 따라서 재배현장에 적용하기 쉽고, 적엽처리 효과가 가장 우수한 Leaf-20 처리가 고온기 적정 적엽방법으로 판단된다.
Abstract
In this paper, we investigated the optimal leaf removal method that is easily applicable to tomato cultivation during spring-summer harvesting period and that improves the yield and quality of tomato produced. Four treatments of leaf removal were experimented: remaining 14 leaves from the growing tip (Leaf-14), remaining 20 leaves from the growing tip (Leaf-20), removing leaves below the truss of which the harvesting is over (Harvest), and removing leaves below the truss when its flowers have been bloomed for 7 weeks (7-weeks). Leaf removal did not affect the flowering speeds very much, but did influence the harvesting speeds and yields greatly. The desirable harvesting speed was found to be 6~7 days per truss. Total yield decreased when the harvesting speed was too fast as 3~4 days due to the application of leaf removal. Leaf-20 was found to be the optimal leaf removal method. 7-weeks treatment showed results similar to those of Leaf-20, but it was inconvenient to apply. Therefore, Leaf-20 was judged to be the ideal leaf removal method in a high temperature environment because it can be conducted easily and bring about the best results.
