Mineral nutrition of plants
The results of studying the influence of non-root top-dressing fertilizers target action, in combination with bioactive agents on the formation of physiologically highly active leave apparatus and growth processes of young apple plants in the orchard nursery are presented.
We studied the system of forming a productive seedling strawberry in the mother planting with the use of growth regulator gibberellin and humic fertilizer Gumi-20K, Gumi-20M, providing an increase of planting stock more than 2 times.
We studied influence of technological methods on the yield and quality of planting stock of strawberry in a mother plantation. Features of formation of quality planting stock of strawberry of different periods of maturing are established with the three-time application of non-root top-dressing by humic fertilizer Power of life.
On the basis of collaborative research by scientists in Russia and Kazakhstan new efficient plant growth regulators were allocated, the use of which ensures high profitability of production of seedlings of fruit crops and grapes.
The analysis of the chemical composition of the apple-tree fruits depending on the level of root nourishment in the intensive plant-ings, on the basis of the results of agrochemical research in the course of experiments with fertilizer of fruit crops is carried out. The equations of dependence between the content of mineral elements in the apple-tree fruit and the content of total forms of elements in the leaves in connection with the level of a root nourish-ment are received.
