摘要
FIELD: agriculture.;SUBSTANCE: method involves ploughing of field and formation of reserve bearing rigs in autumn. Herein, a middle rig is made higher, and axis of rigs is directed to sun rise in the period of seedling emergence. Potato is planted in spring, right after snow melting by placing of vernalise potato tubers of short-season variety between reserve bearing rigs and their covering with soil layer of 5-6 cm, which is partially taken from the base of reserve bearing rigs. Thereafter, the field is covered with pulled transparent film over reserve bearing rings with formation of two slides for weathering. The ends of the film are heeled along the perimeter by soil, forming enclosed space. The film is removed after accelerated heating of ground, emergence of seedlings and their growing up to necessary high, then hilling-up of potato lines is carried out from right and left sides in one pass in spacing through partial movement of soil from the base of reserve bearing rigs onto potato lines. First earlies is dug after potato repining, meanwhile the rigs in which potato was growing are kept. Thereafter, seed vernalise potato of mid-season and late-season varieties is planted to cultivate the second yield in the remained rigs without hilling.;EFFECT: effective use of sun energy and reduction of financial expenses and physical efforts.;2 cl, 1 dwg
