METHOD OF VEGETABLE CULTIVATION, MAINLY CAULIFLOWER, AND SOIL CULTIVATION MACHINE FOR METHOD IMPLEMENTATION Russian patent published in 2009 - IPC A01B79/02 A01B49/06 

FIELD: agriculture.

SUBSTANCE: method involves precedent removal followed by cutting narrow slits. Slits are cut at 0.35-0.40 m pitch to 0.35-0.45 m depth and 0.016-0.020 m width. Triangle-profile groove is made in alignment line of each narrow slit to the depth of 0.50-0.75 of arable layer with 0.15-0.20 m width in top part. Stubby remainders, drops, diseased and non-standard fruit of previous plants are removed from field surface into triangle-profile grooves. Lime at 10-30 tons per hectare rate is applied in a strip over each groove on stubby remnants surface. 40-60% solution of natural bischofite mineral of the formula MgCl₂6H₂O at 600-1200 litres per hectare rate is applied by fine dispersion on surface. Organic fertilisers are applied in late autumn period at 40-60 tons per hectare rate. In early spring period soil cultivation is performed, mineral fertilisers are applied, and seedlings are planted to open ground. Soil cultivation involves ploughing with full layer overturn, terrain leveling, pre-planting cultivation. 30-40% phosphor and potassium fertilisers are applied on surface. Cultivation machine includes frame, bearing wheel, suspension bracket and work tools. Groups of work tools are positioned in sequence on the frame along the machine course and with disposition sideways. Each tool group has slit-cutting strut, mouldboard for triangle-profile groove disclosure, and slanted cutter for shifting stubby remainders, drops, diseased and non-standard fruit of previous plants into the groove.

EFFECT: secured crops of high-quality cauliflower owing to technology and structure.
