The invention provides soybean cultivation technology through narrow
ridge close planting, which comprises the following five steps of mechanical cultivating, precision planting, mechanical deep fertilizing, mechanical weeding and mechanical harvesting. Compared with traditional 'three
ridge cultivation' and other cultivation technologies, the method is small in seeding unit, large in planting density, reasonable in
plant distribution, and convenient to carry out field management such as seeding, fertilizing and weeding. The large
ridge is changed to be the narrow ridge, the ridging space is reduced to be 45cm from 65cm, and 300,000-350,000 seedlings instead of 220,000-280,000 seedlings are kept per
hectare. The mechanical cultivation is carried out in the whole process, the time and the labor are saved, the efficiency is high, and the mechanical cultivating and soil preparing are carried out around the soil environment beneficial to soybean growth; due to rational close planting, the strains of unit area is increased, the
green leaf covering area is enlarged, and natural light, heat and air resources are fully utilized; the narrow ridge close planting gives full play to
population dominance, so that the effect of increasing both production and income is achieved.
