Biologics system of soil maintenance in bastard fallow period

Abstract

The article discusses the results of studies on the effectiveness of the two systems the content of the soil in poluparovy period in case of re-location of a winter wheat in the same field: tillage, adopted in all the irrigated areas of the south (on poluparovoy system or irrigation system polupara) in comparison with the biological system at which to begin treatment of the soil for 3-5 days prior to the optimal duration of grain crops. Under this system, the conditions for achieving a natural plant community in poluparovy period of maximum productivity without making the cost of growing phytomass except irrigation using the existing irrigation network in the fields. The resulting mass - more than 20 t/ha - plowed into the soil, which provides the improvement of its nutrient, water and air modes, increased wheat yield by an average of 0,7 t/ha and getting more 4 tys. rub/ha of additional net income.In the fields allocated for winter wheat after ranoubiraemyh predecessors, creates favorable conditions for the germination of weeds, the formation of the maximum phytomass, and are not destroyed by multiple tillage poluparovoy or another system. Is also reduced to a minimum (3-5 days), the time period between the primary tillage and sowing of winter wheat.
