摘　　要：In view of the problems that the drilling depth can not be adjusted and the amount of liquid injection can not be accurately modulated in the local test device of maize variety breeding and disease resistance,combining the test technical requirements of drilling,liquid injection and sealing of the penultimate radial pitch of maize straw from the ground,a quantitative adjustable liquid injection device for maize stalk center borehole was designed.Its structure,working principle,key technical parameters and practical application effect were elaborated in detail.The field experiment demonstrated that the quantitative adjustable liquid injection device for maize stalk center borehole could meet the requirements of the local test of maize stalk rot.
