The green and efficient cultivation techniques for the spring Glycine max-autumn Brassica rapa rotation system was summarized in the Jianghan Plain area. In this model, spring Glycine max was direct-seeded in open fields in mid-March and harvested from June to July, while autumn Brassica rapa was nursery-raised in mid-July, transplanted in mid-August, and harvested continuously from September to February of the following year. The spring Glycine max cultivation techniques include: selecting cold-tolerant, disease-resistant, high-quality varieties (Taiwan 75-3); choosing fields with non-legume and non-cruciferous previous crops; applying sufficient decomposed organic fertilizer and compound fertilizer as base fertilizer; finely preparing land and constructing deep-trench high-ridges; seeding precisely using narrow-ridge double-row or wide-ridge four-row methods after seed dressing with chemicals; adhering to the “dry flowers, moist pods” water management principle during field management, with scientific topdressing at the seedling, initial flowering, and pod-filling stages; comprehensive use of agricultural methods (selecting disease resistant varieties, reasonable planting), physical methods (hanging insect traps), and chemical methods (20% imidacloprid, 200 g/L chlorantraniliprole) to control pests and diseases such as aphids, pod borers, and rust; pods were harvested when they were plump and bright green, and plant residues were either treated harmlessly or returned to the field. The autumn Brassica rapa cultivation techniques include: selecting suitable varieties (Jingyoulianghong series); nursery-raising under rain-shelter and shading in summer; applying sufficient base fertilizer after Glycine max straw incorporation, followed by high-ridge transplanting; topdressing in stages combined with irrigation after seedling recovery, at bud emergence, and during stem harvesting; implementing integrated measures to control diseases and pests such as soft rot, downy mildew, aphids, and flea beetles; harvesting when the main stem reaches 30 cm; and standardizing post-harvest bundling, pre-cooling, and packaging to maintain product quality. This rotation model achieves year-round high yield, improved quality and efficiency, and sustainable soil use of Glycine max and Brassica rapa, provides a reference for efficient legume and vegetable production in similar ecological regions.
