This invention discloses an efficient cultivation method for crop rotation of mung beans and Chinese cabbage. The method includes: (1) treating spring mung beans with seed priming one week before sowing, sowing in late March, harvesting in early June, and returning the straw to the field after crushing; (2) sowing seedling Chinese cabbage in mid-June and harvesting in late July; (3) sowing summer mung beans in late July and harvesting in early October, and returning the straw to the field after crushing; (4) sowing Chinese cabbage in mid-September for seedling cultivation, transplanting in mid-October, and maturing in late December. This invention adopts a scientific and reasonable crop rotation model, which can achieve four crops and four harvests a year, significantly improving land utilization. By planting mung beans for nitrogen fixation and returning straw to the field, soil fertility is improved, and the amount of fertilizer used for vegetable cultivation is reduced. By combining the planting of miscellaneous grains with vegetable cultivation, food security and vegetable supply are ensured, achieving significant economic, social, and ecological benefits.
