METHOD OF ACCELERATED REPRODUCTION OF TUBER CROPS Russian patent published in 2017 - IPC A01G1/00 

FIELD: agriculture.

SUBSTANCE: method includes stimulating the growth of etiolated sprouts by means of cutting the apical part and treatment with a solution of thiourea, germinating tubers in the darkness at a temperature of 14-16 °C and relative humidity of 90-95%, alienating the apexes from the basic etiolated sprouts of the first order at the time of formation of 3-4 nodes on the basic etiolated sprouts of the first order, planting the tubers in the soil at the formation of 3-5 lateral etiolated shoots of the second order and shoots of callus origin, on the basic etiolated shoots of the first order, dusting the tubers after planting with humus soil with the layer of 10 cm, and after the sprouts have reached the height of 21-25 cm above the humus soil level, dusting the shoots with a nutrient substrate of a different density, re-dusting several times as the sprouts reach the height of 21-25 cm above the substrate level, leaving at the dusting the tops of the shoots with a length of 1-5 cm free above the substrate surface, reducing the substrate density with each dusting. Planting the tubers is carried out in blocks with the formation of the distance between the ridges and the row spacings according to the scheme: [(2g₁+g₂)_(m₂+m₁+m₂)], where g₁ is the distance between the ridges of 40 cm; g₂ - the distance between the ridges of 50 cm; m₁ - the distance between the row spacings of 40 cm; m₂ - the distance between the row spacings of 50 cm, and the block plantation is formed according to the scheme: (m₂+ m₁+ m₂)⋅n, where m₁ is the distance between the row spacings of 40 cm; m₂ - the distance between the row spacings of 50 cm; n is the number of blocks in the plantation.

EFFECT: reducing the proportion of manual labour and the ability to use the technology in the technological process of growing potatoes.
