METHOD OF VEGETATIVE RECLAMATION OF SECONDARY SALINISATION LANDS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agriculture and land reclamation. Method includes one-year soil preparation and sowing. In the first decade of May, hefts of licorice rhizomes are simultaneously linearly planted into prepared soil in a wide-row manner into harrows for depth of 0.12-0.16 m with a norm of 4-5 pcs per running metre, and girasol tubers with diametre of 2.5-6.5 cm are planted in amount of 6-8 pcs per running metre. Post-planting rolling is carried out. Perpendicularly to direction of hefts and tubers planting, dog-grass seeds are sown in a narrow-row manner with width of spaces between rows making 0.075-0.30 m for depth of 6-8 cm with norm of sowing equal to 16-22 kg of germinating seeds per ha, and soil is rolled with star-wheeled rollers. At the same time width of spaces between rows in plantations of licorice hefts and girasol tubers relates to width of spaces between rows in plantations of dog-grass as (37-18): 1.;EFFECT: method provides for faster introduction of secondary saline lands in rice bays in crop rotation at 5th or 6th year of mesohalophyte plants growth.;2 cl, 2 dwg, 1 tbl
