FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular to horticulture and gardening, and can be used for growing fruit and berry crops and vegetables on private farms. Device for the formation of seedbeds in the soil consists of polyhedral rod 2 on which there is a polyhedral cone-shaped constriction, cup-shaped limiter 8 and replaceable form-builders in the form of a cone with a curved end, in the form of a sphere or a conical cylinder, and retainer 10 creating a support for the rod. Seedbeds in the soil are formed by rotating a polygonal rod in a circle, giving the seedbeds a cone-shaped cross-section, and then a pit-like seedbed, while a clay solution is added to strengthen the walls of the seedbeds in sandy soils, and in the clay soils, a reinforcing material in the form of sand or organic materials from crushed wood, grass or humus is added.
EFFECT: proposed invention will increase the depthward volume of the root layer of trees with a reduction in the root propagation area along the crown projection, and also increase the wind resistance of the gardens.
