The 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
In 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
Alternation 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
