METHOD TO CULTIVATE POTATOES, MOSTLY FOR AREAS OF RISK FARMING

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to the field of agriculture. The method includes zonal main and pre-planting treatment of soil, selection of early-ripe kinds, planting of tubers, post-planting and vegetation watering, maintaining the threshold of least moisture capacity in the active layer at the level of 80% minimum water capacity, taking care of soil and plants, harvesting tubers in industrial ripeness. At the same time the date of tubers planting is determined from the following expression: C_n=A_i-B_n-D_n, where C_n - time of planting, month and date; A_i - calendar time of the first stable frosts, days; B_n - vegetation period until ripening of tubers to industrial ripeness, days; D_n - preemergence period, days, at the same time in the period from planting to start of budding phase in the layer of 0-0.2-0.3 m, the lower threshold of moisture is maintained at the level of 80% minimum water capacity, and further in the layer of 0-0.6 m.;EFFECT: method provides for harvesting of guaranteed crop in industrial ripeness before stable frosts start.;3 tbl
