Abstract

The results of the study of soil moisture reserves during the growing season showed that they are maximal in April. By this time the first meter of soil rangelands it is 98.2 mm, for the first option agrophytocenoses - 109.5 mm, the second - 112.3 mm, the third - 156.6 mm. Comparison of the amount of moisture produced from phytocoenoses products allowed the calculation of production rates of water that make for a natural pastures 1500-4900, for the first option - 465-910, the second - 450-760, the third - 640-700 kg of water to create 1 kg of dry matter .Arid regions of Russia, covering a vast area, have great economic value and have an exceptional natural resource potential. The total area of drylands by a factor of aridity 0,11-1,00 over 120 million hectares. Here lived and worked about 30 million people, produces more than half of the total produced in the Russian Federation, grain, meat, milk, vegetables, fruits and berries.

STRUCTURE AND PRODUCTIVITY OF MULTICOMPONENT AGROPHYTOCENOSES FOR CASPIAN ARID ZONE

Abstract

The results of the study of soil moisture reserves during the growing season showed that they are maximal in
April. By this time the first meter of soil rangelands it is 98.2 mm, for the first option agrophytocenoses -
109.5 mm, the second - 112.3 mm, the third - 156.6 mm. Comparison of the amount of moisture produced
from phytocoenoses products allowed the calculation of production rates of water that make for a natural
pastures 1500-4900, for the first option - 465-910, the second - 450-760, the third - 640-700 kg of water to
create 1 kg of dry matter .
