The use of liquid complex micronutrients for the growth and development of robinia pseudoacacia and crimean pine in arid conditions

Submitted by Гость (not verified) on Mon, 07/29/2024 - 22:38

The article presents data on the results of testing complex micronutrients when sowing seeds of Robinia pseudoacacia L. and Pinus nigra subsp. pallasiana (Lamb.) Holmboe. at a production nursery. Stratification provides seeds with rapid germination under optimal conditions of oxygen access and maintaining a humidity level and temperature of 10°C. Fertilizers “Volski Biochem” are able to increase the energy of germination of seeds of the studied species, increase their growth rate and contain all the necessary nutrients for plants.

High productivity and longevity of animals are the key challenges in modern dairy farming. In addition to high milk yields, first-calf heifers also have to increase their body weight. Due to their physiological characteristics, they are unable to consume large amounts of bulky forage to provide energy and nutrients for potential productivity. One of the ways to solve this problem is to increase the feeding level of first-calf heifers at the expense of concentrates.

Clonal micropropagation of grape varieties of interspecific origin Moscow white (Vitis amurensis Rupr. x Vitis vinifera L.) showed that on the 40 th day of the animation stage, a mono-podial type of branching is typical for micro-plants, and there is no diaphragm in all nodes of micro-shoots. On the 120 th day of growing in containers, the researchers revealed that the nodes of the plant shoots, from the 1 st to the 6th, have a monopodial branching type. Parenchymal cells which form an incomplete diaphragm are present in the seventh node.

Thymus vulgaris L. and Thymus serpyllum L. are sought-after medicinal plants in many countries of the world for their essential oils, flavonoids and tannins. The species of this genus are extremely polymorphic, both in their morphological and anatomical structure and in their biochemical composition. Stomata play an important role in growth and yield formation. The study of the stomatal apparatus and its features is a relevant research topic for agricultural crops.Eight specimens of Th. vulgaris and three specimens of Th.

The authors carried out studies at the experimental field station of Russian State Agrarian University - Moscow Timiryazev Agricultural Academy in 2008-2020. The study aimed to determine the resistance of white clover in mixtures with various types of grasses with two- and three-cut clipping treatments. In the experiment with four to five-component mixtures, the proportion of white clover reached 36-53% in the botanical composition of swards with the content of perennial ryegrass in the fourth year of life. It did not exceed 22-23% in the mixtures with cock’s foot.
