The invention provides a matching planting method for multi-span greenhouse mechanical production. The method comprises the steps of chili seed preparation, seedling growing substrate preparation, chili seedling preparation, fertilizer applying for soil, deep scarificationploughing and rotary tillage, after the deep scarification ploughing and the rotary tillage, and soil is divided into a basic layer with large and compact particles and a soft growing layer; a ridger is used for ridging along the trend of a greenhouse; a multi-functional mulch applicator is adopted for completing the work ofdrip irrigation zone laying and mulching film laying; a full-automatic or semi-automatictransplanter is adopted for conducting transplanting and planting on chili seedlings with the seedling age of 45-50 days, the plant height of 15-18 cm and 6-8 main leaves, the chili seedlings are transplanted and planted in a growth layer, and seminal leaves are flush with the ground. According to the method,through mechanical planting for chili, it can be avoided that the soil is hardened or compacted manually, the root systems of the chili can effectively breath normally, the chili can conveniently absorb nutrition, and the problems that the labor intensity of manual planting for the chili is high, the amount of the labor used is large, and the production cost is gradually increased are solved.
