METHOD FOR CULTIVATING WINTER RAPESEED FOR SEEDS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agriculture, in particular, to crop production, and can be used in cultivation of winter rapeseed in conditions unfavourable for overwintering. The method includes a complex of cultivation techniques, consisting of operations in tillage, preparation of seeds for sowing, autumn seed sowing, management of crops in the autumn, and treatment of the crops with a fungicide. 50 kg/ha of DAP are introduced for pre-sowing tillage. Winter rapeseed varieties with a seeding rate of 5 kg/ha with increased winter hardiness are sowed 85 to 90 days prior to the end of vegetation jointly with spring rapeseed with a seeding rate of 3 kg/ha. In the 5 to 6 phase of the foliage of the main crop, the plants are treated with the Karamba Duo retardant fungicide. In winter, the spring rapeseed plants with a height of 70 to 90 cm act as hedges for accumulation of snow.;EFFECT: method increases the survival rate of winter rapeseed plants in extreme overwintering conditions, thereby allowing for stable yields and an increase in the productivity of crops.;1 cl
