WAY OF MELIORATION OF IRRIGATED CHERNOZEM SOIL

摘要

FIELD: agriculture. ^ SUBSTANCE: way of melioration of chernozem soil contains cyclic interleaving irrigated and a bogharic agriculture using of crop rotations systems for hygrophilous and drought-resistant crops. At revealing of chernozem soil degradation from 10 to 20% from all area of irrigated lands in an eight crop rotation system hygrophilous irrigated crops are bred for two-three years. It reduces a ground water table and a secondary salinization of chernozem soil. At degradation revealing above 20 to 35% from a total area of chernozem soil the salt tolerant crops in eight crop rotation system are bred for plough layer moving. In this case at harvesting of these crops together with vegetative mass sulphates of salts will be removed. At revealing of chernozem soil degradation on the area above 35 to 50% from a total area of irrigated lands drought-resistant crops are bred and transfer them in a bogharic agriculture conditions. ^ EFFECT: aftereffects of a regular long-term irrigation of soil are decreased and productivity of crops increases. ^ 1 tbl
