High-stress-resistance crop seedling breeding machine

The utility model relates to the technical field of crop cultivation accessory devices, in particular to a high-stress-resistance crop seedling breeding machine which can enable multiple sets of high-stress-resistance crop seedlings to be separated from one another and not to influence one another in the growth process and improve the breeding accuracy. In addition, water can be cultivated for high-stress-resistance crop seedlings in time, and the growth speed of the high-stress-resistance crop seedlings is increased; the device comprises a breeding box, a breeding cavity is formed in the breeding box, a breeding opening is formed in the top of the breeding box, and a breeding cover plate covers the interior of the breeding opening; the breeding device further comprises a multi-component partition plate, a base, a water tank, a purification tank and a water pump, the bottom of the multi-component partition plate is evenly installed at the bottom in the breeding box from left to right,and a certain distance ex
