APPLE TREES IN RIDGE PLANTING |
| Authors: | J. Sako, E. Laurinen |
| Abstract:
Planting the trees on a low, about 30 cm high, ridge covered with a plastic film has proved a useful method in growing apple trees under Finnish conditions. The trees have shown better growth, productivity and winter-hardiness compared to those grown on flat soil. The growth of the trees has been more vigorous, which has led to earlier and heavier yields. The growth ceases earlier at the end of the season and, especially after wet autumns, the trees have wintered with less frost injuries than those growing on flat soil. The better performance of the trees in ridge planting is due to the more favourable moisture conditions and to the higher soil temperature as compared to planting on flat soil. | |
