Экономическая эффективность садовых конструкций яблони сорта уэлси на подвоях различной силы роста

Abstract

The article gives data obtained from long term observations of yield efficiency, market fruit qualities and economic effectiveness of cultivating orchard constructions with various planting density, involving three apple cultivar - rootstock combinations of various vigor. As a result of the conducted research it was established that planting density influenced sufficiently the productivity of cultivar - rootstock combinations. Yield efficiency (per tree) corresponded to the feeding area and was higher in less dense plantations. In dense plantations yield efficiency (per area unit) was higher but market quality of fruits was inferior. The following planting designs were distinguished by the complex of economic effectiveness indices for cultivar - rootstock combinations: ‘Wealthy’ on insertion of dwarf rootstock № 134 - 4 × 2 m, ‘Wealthy’ on semi - vigorous rootstock 5 - 25 - 3 - 4 × 3 m, ‘Wealthy’ on seedling - 5 × 3 m.
