SMALL-LEAVED LIME (TILIA CORDATA) CULTIVATION IN THE OMSK REGION SOUTH FOREST-STEPPE CONDITIONS
06.00.00 Agricultural sciences
DescriptionSmall-leaved lime (Tília cordata) is wonderful species of trees, producing honey. This tree species is not cultivated in forest tree nurseries of Head forestry department of the Omsk region for the purpose of an artificial reproduction. Small-leaved lime grows wild in Bolshyi Uki, Ust-Ishym and Tevris areas. This forest is the basis for a honey production. Small-leaved lime occupies a very small area, which equals 1,5 ha. Natural reproduction of small-leaved lime in the Omsk Pryirtysh district is a reliquiae. Questions of reproduction of small-leaved lime have not been studied yet. Shoots cloning of small-leaved lime has an important practical value for areas of natural reproduction. A technology of seed reproduction has not been developed for the Omsk region. Complexity of the matter is in the existence of a long and deep physiological quiescent period of small-leaved lime seeds. Experimental facts of small-leaved lime seed reproduction has been described in this article. Results of measuring of height and root neck diameter of oneand two-year old plants have been shown. The influence of putting young plants in the shadow on their growth and development has been evaluated. It has been shown that seedlings received from small-leaved lime growing in the Оmsk State Agrarian University Dendrology Park have large variation in the growth and development parameters and the fact of casting shadows on the plants truly affects the height of oneand same as two-year old samples

DescriptionAlternation of crops, will remain a fundamental element of zonal technologies of their cultivation for a long time. Application of methods of mathematical model operation will allow to come to new level in the solution of the questions of effective use of an arable land, through application of models optimizing it. Results of researches which basis data of long-term observations are will be especially valuable. They used data of the long-lived stationary experiments on studying of alternation of crops in crop rotations of last more than five rotation. Stationary experiences are located in a forest-steppe zone of Western Siberia on the fields FGBNU "SIBNIISKH". The purpose of researches consisted in optimization of use of an arable land at application of methods of mathematical model operation for preservation of soil fertility. The model allowing when performing particular conditions is given in work (balance of a humus, work expense, a metabolic cost, etc.) to optimize use of an arable land against the background of preservation of soil fertility of the soil, receiving production, economic and power efficiency. It is shown that at alternation of grain crops with clear steam, formation of a harvest happens due to natural fertility of the soil what the negative balance of a humus which reaches 0,18 – 0,78 tons from hectare testifies to. At alternation of field cultures without clear steam the harvest was formed against the background of reproduction of organic matter of the soil, due to increase in vegetable oddments from use of fertilizers, the balance of a humus was positive – 0,15 – 0,28 tons from hectare. Use along with clear steam, busy steam, colza on green fertilizer, and also straw as organic fertilizer for grain crops, 2,01 tons from hectare of commodity grain were received, at a share of clear steam – 16,8%, busy steam – 11%, summer grain – 72,2% of arable land. Increasing in crop rotations of West Siberian Square with use as organic fertilizer of straw, busy vapors and green fertilizers, it is possible to achieve reproduction of fertility of the soil with some decrease in an exit of commodity grain to 2 tons from hectare

DescriptionThe article presents the results of studies on the influence of predecessors and funds of intensification on the yield of spring wheat in the field crop rotations. Studies carried out in the long stationary experiment in crop rotations over the past seven rotations. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia

DescriptionThe application of bioactive preparations during taking root of green cuttings conifers family of Cupressaceae has been described in this article. Longstanding experiments of growing planting stock with open and closed roots have been realized. Increase of taking root, apical growth and development of root’s system by positive influence of preparations has been shown

DescriptionIn the long-term stationary experiment since 1968, we have studied the influence of crop rotation on soil fertility and productivity. The modernization schemes of field rotations in the direction of alternation crop change were held 40 years later, by introducing a scheme of oilseeds (canola, soy). According to the research, the authors made conclusions about the efficiency of cultivation of oil crops in crop rotations in the region. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia
