The article provides information about the impact of the main methods of tillage crops on weed management component agrocenosis of winter wheat
There were determined the close correlation dependence
between the energy of propagation of wheat seeds sunk
in water in which the grape cuttings were rooted on one
side and the rooting and output of cuttings with three
roots and more on other side by the authors. There were
the equations of regression for prognosis of rooting and
output of cuttings with three roots and more
This article features the recommendations on microclonal grapes reproduction at all stages of their realization
In January 2015, at the Vineyard and ZAO "Pobeda" in Temryuk District of the Krasnodar region, the thermometer dropped to minus 21,6 C, which resulted in significant damage to the central wintering buds. The article presents a method of determining the degree of damage of wintering buds. Based on the results of inspection of variety by sections divided into 3 groups.
Group 1: saved between 40 and 72% central. This group includes the following 7 varieties : Pervenets Magaracha (uch. 64) Gibernal (uch. 74/3), Viorica (uch. 77), Riton (uch. 66), Riesling (uch. 82), Traminer (uch. 73/2), Chardonnay (uch. 73/3). Cutting of bushes should be carried out by the usual way. The task of cutting - compensate the loss of crops due to leaving the greater load. Group 2: Central buds was damaged nearly 70-85%, saved from 20 to 35% of replacement buds. This group includes Merlot (uch. 83), Tsitronyy Magaracha (uch. 69), Augustine (uch. 66), Saperavi (uch. 79), Chardonnay (uch. 74/1), Muscat white (uch. 73) Cabernet Sauvignon (uch. 80). During cutting should be left as much as possible of annual shoots and well-developed secondary shoots. Group 3: damaged more than 85% of central buds, replacement buds significantly damaged . To this group assigned Saperavi (uch. 80), Pinot blanc (uch. 74), Merlot (uch. 80/2), Moldova (uch. 70), Chardonnay (uch. 68), Moldova (uch. 22) Kaberne- Sauvignon (uch. 68), Moldova (uch. 38), Arkadia (uch. 78), Tsimlyansky black (uch. 68). Pre-cutting consists in removing all clearly dead and unusable parts of the bush (dried vines, stumps, annual shoots) that will accelerate the development of shoots from the angular buds and resting buds. Considering the high plasticity of grape plants, can not only in accelerated way to restore the crown of bushes damaged by frost, but also get a crop in the current year, using special methods of agricultural technology
Ragweed plant became quarantine malware on the
territory of Southern Russia. In the Krasnodar region it
has been extended to the territory of more than 4.62
million hectares. In the areas of its growth, it causes
great damage to agriculture. By developing a strong
root system and aboveground, it inhibits the row crops,
especially sunflower. Another problem with this weed
is producing large amounts of pollen that causes
allergic reactions in the majority of residents of the
province. This article discusses the importance of
using modern methods of ragweed oppression,
including chemical and biological methods in
sunflower crops
In the article, there were determined the physiological parameters of resistance of stocked plants to in-creased pH soil. There was shown, that the resistance of apple-trees to the action of edafic stress-factors achieved in the case of their grafting on average-growing clone stock MM 106
Growing of crowning yearlings in garden nursery depends on elements of agricultural machinery, which have different effects on the angle of divergence and the number of skeletal branches formed. With the reduction of the period of growing branched yearling costs are lower for planting material, because of exception work in the nursery with two-year seedlings
The obtained experimental data show that the incorporation of trace elements into the system of the sunflower crop has a positive impact on the mineral nutrition of plants, the number and quality of the crop. Foliar feeding of sunflower crops with micronutrients improves nutrition of plants with nitrogen, phosphorus and potassium, thus creating the preconditions for the formation of highly agrocenosis. The seed yield of sunflower increased by variants with application of micronutrients 1.2-3.5 t/ha or 4.4-12.9 percent. The greatest impact of treatment with boron and copper, exceeding the background option 3.1-3.5 t/ha or 11.5-12.9% respectively. The crop is least influenced by manganese and molybdenum. The examined elements positively influenced the structure of the sunflower crop. The greatest influence on the diameter of the basket, the number of seeds, weight of seeds in the basket, the weight of 1000 seeds was provided by the zinc and copper. Trace elements contributed to the improvement of quality indicators of sunflower. For husk content, the greatest positive effect was cobalt, zinc, manganese and copper, increasing the background option 10.1, 10.4, 10.5 and 10, and 6%, respectively, on the oil content of sunflower seeds had cobalt, copper and zinc. The oil content on these options amounted 55,0, with 55.1 and 55.2%, respectively, increasing this figure by 1.5 to 1.7 %. The acid number at variants with boron, manganese and zinc was the same with the background option and amounted to 1.8. The greatest influence on iodine number provided molybdenum, zinc and copper, which accounted for 170,5, 171,2 and 171,4, exceeding the background option 10.2 and 11.1
In article the problem of environmental pollution by veterinary antibiotics and acquisitions of resistance of pathogenic microorganisms to them is considered. In the conditions of field experiment resistance of chernozem microorganisms to pollution oxytetracycline and tylosin is studied
The accumulation of heavy metals was studied in different component parts of a White squash (skin and flesh, flesh, seed skin, seed kernel, peduncle). It is known that the basic source of feed for agricultural crops are mobile water soluble organic and mineral soil combinations which are polluted by heavy metals in different degrees. In the process of their migration they are able to accumulate in different parts of plants or to disperse. The mechanism of quantitative estimation of migration of heavy metals in direction of removal of mobile water soluble soil combinations to various parts of a White squash is developed by the author. The ranks of mobility of heavy metals are made from the most mobile manganese to the most indifferent iron. The model of estimation of mobility of the rest spectrum of heavy metals is chosen, namely: lead, cadmium, zinc, copper, nickel, cobalt in relation to manganese and iron. Basing on the position of a separate element in a mobile rank and its concentration it is possible to define the source of entering to a squash fruit. It may be water soluble soil combinations, irrigation water and atmospheric aerosols
