Ресурсосберегающие технологии возделывания сельскохозяйственных культур в экологически сбалансированной системе земледелия

Abstract

Complex studies were conducted in eight-field grain-steam-crop and grain-steam-tilled crop rotations using the following terms: fertilizer systems, plant protection, basic tillage methods and plastic varieties. Scientific novelty lies in the fact that for the first time in the forest-steppe of the Volga region, on a systemic basis, resource-saving technologies have been developed on the basis of fertile crop rotations in an ecologically balanced, biologized farming system. Agroecological principles of conservation and reproduction of gray forest soil fertility and obtaining a planned harvest of high quality. Experimental substantiation of the role of action and interaction of the main factors of saving technology, in increasing crop productivity of crop rotations, productivity of arable land and soil fertility. Agroeconomic evaluation of the resource-saving technology effectiveness. Crop rotations of leguminous crops and perennial legumes increase the productivity of arable land to 15-20%, provide a positive balance of humus (0.45-0.5 tons per hectare). Organomineralic fertilizer system reduces the need for mineral fertilizers by 2-3 times, ensures the receipt of planned high quality harvest and reproduction of soil fertility. The integrated plant protection system, using biological means and methods, provides a saving of plant protection products to 30-35%, raises productivity to 15-25%. Moisture-resource-saving mode of soil cultivation (mulching various deep loosening without turnover of beds) allows to save 25-35% of fuel and reduce the moisture loss to 35-40%. Complex application of these factors with the use of high-yielding plastic varieties makes resource-saving technology that increases the productivity of cultivated crops and the productivity of arable land by 1.5-2 times, the profitability of production by 30-50% and ensuring the reproduction of soil fertility.
