METHOD OF INTENSIVE GROWING OF POTATO UNDER DRIP IRRIGATION

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, in particular to crop production and can be used for potato production under drip irrigation. The method includes preplant sorting of tubers in a solution of urea, with the density of 1.08 g/cm³. The tubers are treated in 3-4 daily suspension of Chlorella Vulgaris, 1-2 l of the suspension per 50-100 kg of tubers. Double processing of plants is carried out in the full seedling stage and the beginning of flowering with a growth regulator - Lignohumate, the solution concentration of 0.01-0.02% at the rate of 120-130 g/ha. Mineral fertilisers are applied with irrigation water on a background of differentiated irrigation regime at a dose of N₉₀P₉₀K₁₂₀. At the critical growing season in the stage of budding - flowering the lower threshold of humidity is maintained at 75-80% of the HB.;EFFECT: use of the claimed invention enables to grow potatoes with low content of reducing sugars and high content of starch and vitamin C.
