Influence of landing depth on morphological and biological signs of widely applicable in the greening flower-decorative cultures (Antirrhinum majus L., Petunia hybrida Vilm., Salvia splendens Sello ex Nees, Zinnia elegans Jacq.)

Abstract

Information on the characteristics of the growth and development of plants of large snapdragon, hybrid petunia, sparkling sage, elegant zinnia, depending on the depth of planting is provided. Characteristics of the main morphological signs are given, data on the height of plants, the number of lateral axes, buds, flowers, fruits, leaves, weight and number of roots of deeply planted and control plants are presented; provides information on vegetation periods; ways to improve the agricultural technology of transplants of indicated plants are identified. It is shown that deep planting is an economically viable rational agricultural method that helps to increase the decorativeness of plants, their earlier, long and plentiful flowering, and to improve the aesthetic expressiveness of flower beds without additional labor and material costs.
