Espalier fruit plant and heating device for such an espalier fruit plant

摘要

Espalier fruit plant, in particular a wine-growing plant, for fruit plants (20) placed in a row (100), which can be fastened to a fastening wire (32), preferably a wire frame structure (30), the fastening wire (32) being stretched between support posts (31) of a row of plants (100) and wherein a heating device is provided, characterized in that the heating device for each row of plants (100) has at least two hollow profiles (40; 40.1, 40.2) lined up at the end with a longitudinal extension along a longitudinal axis (104) and one in the hollow profiles (40; 40.1 , 40.2) has a guided heating cable (10) which is fastened to the fastening wire (32) via the hollow profiles (40; 40.1, 40.2), and that the heating device furthermore has connecting sleeves (50) for connecting hollow profiles (40; 40.1, 40.2) in a row. having with each other in the area of their end faces, the connecting sleeves (50) either being designed in this way either at a first end (43.1) of a first hollow profile (40.1) They are formed or fastened so that they are fixed in the longitudinal direction with respect to the first hollow profile (40.1), and the other hollow profile (40.2) adjoining the first end (43.1) of the first hollow profile (40.1) at a second end (43.2) in such a way are fastened with a sliding seat that enables relative displaceability between the connecting sleeve (50) and the other hollow profile (40.2) in the longitudinal direction, or in each case at a first end (43.1) of a first hollow profile (40.1) and at a second end (43.2 ) another hollow profile (40.2) adjoining the first end (43.1) of the first hollow profile (40.1) on the face side are fastened in such a way that they are fixed against displacement in the longitudinal direction with respect to the hollow profiles (40; 40.1, 40.2), the connecting sleeves (50) having a region of elasticity which acts between the hollow profiles (40; 40.1, 40.2) adjoining one another at the end and which enables the hollow profiles (40; 40.1, 40.2) to be displaced relative to one another in the longitudinal direction.
