Description

  The present invention relates to a one-stage densely planted cultivation method and apparatus for tomatoes capable of harvesting only the first inflorescence in ultra dense planting and capable of high-level stable production of 4 crops per year.

  In the cultivation of tomatoes, one-stage dense planting that increases the yield per unit area while reducing quality risk has been proposed. This one-stage dense planting cultivation is a cultivation method in which about 10,000 strains are grown per 10a, and only the first inflorescence is grown, and the fruit of this inflorescence is grown and harvested.

  According to this one-stage dense planting, there are few risks in cultivation, and there is an advantage that a yield of more than twice the conventional per unit area can be expected. On the other hand, the labor time required for cultivation management has a disadvantage that it increases compared to conventional cultivation, and a considerable amount of labor is required because of a large amount of harvest.

  That is, in the one-stage dense planting, seedlings are densely planted at a narrow interval, and as the growth progresses, many branches and leaves cover the flowers and fruit bunches, preventing sunlight. For this reason, in order to efficiently grow the first inflorescence, it is necessary to arrange these branches and leaves. However, this branching work is a time-consuming work that is not in conventional cultivation, and the labor associated with this work increases the working hours of one-stage dense planting cultivation.

  Patent Document 1 describes a conventional one-stage dense planting method. In this cultivation method, after planting a plurality of tomato seedlings on a hydroponic bed installed in the north-south direction, the two branches and leaves above the first inflorescence are pushed upward, and the branching means It is described that fixing the tip portion so as to be located above the base end portion allows all the leaves, flower bunches, fruit bunches on which they grow, and the branches and leaves under them to be sufficiently exposed to sunlight. .

  According to the one-stage dense planting method, the branching work of pushing up and fixing the tip side of the branches and leaves above the first inflorescence in the early stage of growth was an important work. For this reason, in the conventional branching work, a so-called sorting and attraction method is used in which a stem is tangled with an attracting string that is vertically arranged and installed from above the cultivation tank.

  In the branching means described in Patent Document 1, two induction lines are installed on the east side and the west side of the hydroponics bed, and the stems of the branches and leaves are entangled with the induction line, and the leading ends of the branches and leaves are located upward. The branches are arranged to push up.

  In this way, the branching work in the conventional one-stage dense planting method requires the work of fixing the branches and leaves to the attracting string, and this work has been a factor that increases the working hours of the first-stage dense planting cultivation . Moreover, since such a branching operation is required four times a year, the labor time required for the cultivation management of the worker will be extremely increased, and in order to increase the yield more than twice the conventional per unit area. More than twice the working hours of customary cultivation.
