Efficient crop breeding device

The invention relates to the technical field of plant breeding, and discloses an efficient crop breeding device which comprises a planting bin and a space for providing crop growth, a plurality of mutually isolated bins are arranged in the planting bin, a plurality of layers of planting frames are arranged in each bin, a planting disc is arranged on each layer of planting frame, the planting disc is filled with a matrix, and the matrix is arranged in the planting bin. The substrate is used for planting seeds and seedlings of crops; the environment adjusting system is used for adjusting the growth environment of crops in each bin; the detection system is used for detecting growth conditions and genetic characteristics of crops in the planting bin; and the screening system is used for screening and classifying the crops detected by the detection system according to preset target characteristics. Through cooperation of the planting bin and the environment adjusting system, the optimal growth environment is provi
