FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Method involves formation of soil for tubers bedding, laying onto the soil of tubes with droppers, covering the soil with a protective screen, tubers planting and water supply from droppers. Rolls with flat slopes are formed on the field, tubes with droppers are laid along the top of the rollers. Potatoes are planted in rows in rollers ridges, and the protective screen is made in the form of tape from membrane material with width covering on both sides of rolls of rows of potato planting. Prior to planting, soil is prepared by performing plowing on a dry field, along which organic solid fertilizers are applied simultaneously with supersorbent granules and performed in one pass with the unit. Each strip of organic fertilizer is covered with a coaxial with it strip and equal in width band of the supersorbent. Then, soil harvester is plugged with disc harrows into the soil layer to depth of 20–22 cm, and organic solid fertilizers with supersorbent granules are plowed afterwards. Rollers with flat slopes are formed from mixed soil; sorbent granules act as aggregator of water capable to absorb water by means of irrigation with tubes with droppers. Watering of rolls with upset tubers in rows is performed with reduction of soil moisture in layer of dry formed roller. Water supply is performed with drip irrigation with allowable flow rate through each dropper and duration, providing for gradual absorption of drop liquid and simultaneous water intake by supercorborent granules in roll soil. In critical period of vegetation, in stage of budding – flowering, lower threshold of moisture content of roller is maintained due to release of granules of supersorbent from water. Protective screen is made in the form of tape from membrane material with width covering pots rows on both sides of the roller. Irrigation pipe is a dropper with holes in the side lower wall of the tube, which from above are covered with enveloping short tubular branch pipes, inside of which they are equipped with tubular porous material, providing for water outlet through free end along length of short tubular branch pipe. At that, after it towards the hollow slope on the tube below the hole the reflector-screen is fixed in the form of a resiliently elastic plastic fixing tubular plate, the edges of which have bent along the circumference side wall towards the water outlet direction, and droppers in the form of a short tubular branch pipe and a deflector-screen have the possibility of horizontal movement along the length of the irrigation pipe.
EFFECT: method ensures expansion of technological capabilities and production of ecologically clean potato tubers products.
