and B, a fertilizer supply process of the fertilizer powder feeder in the step two: the cam ring body (13) synchronously rotates along with the transmission shaft (31) due to the rotation of the transmission shaft (31), and the lower end of the cam mandril (21) is provided with a ball top (20) which is always in downward contact and presses the outer contour surface of the cam ring body (13) under the action of the relaxation force of the spring (7); the rotation of the cam ring body (13) is linked with the cam mandril (21) to do periodical up-and-down pushing action, so that the powder transfer shaft (11) does up-and-down pushing action along with the cam mandril (21) while doing rotary motion, the powder transfer shaft (11) does up-and-down pushing action once when the cam ring body (13) rotates for one circle, because the cam lift of the cam ring body (13) is more than twice of the axial dimension of the fine channel (12), the amplitude of up-and-down displacement of the powder transfer shaft (11) is more than twice of the axial dimension of the fine channel (12), therefore, in one rotation period of the conveying shaft (31), at least one powder transfer ring groove (24) can move downwards from the powder mixing and stirring cavity (5) and reach the coarse channel (22) through the fine channel (12), and at least the powder in the powder mixing and stirring cavity (5) is quantitatively transferred into the coarse channel (22) once through the powder transfer ring groove (24) in the process, the fertilizer powder moving downwards into the powder transfer ring groove (24) in the coarse channel (22) can be rapidly scattered into the coarse channel (22) under the rotating centrifugal action of the powder transfer shaft (11), finally the fertilizer powder scattered in the coarse channel (22) is downwardly scattered to the middle part of the fertilizing conveying channel (17), and the fertilizer powder entering the fertilizing conveying channel (17) is rapidly mixed with a soil source fed leftwards in the fertilizing conveying channel (17) under the stirring of a plurality of stirring rods (15); with the continuous rotation of the transmission shaft (31), the mixed fertilizer powder in the powder mixing and stirring cavity (5) is quantitatively transferred into the coarse channel (22) once through the powder transfer ring groove (24) in each rotation period of the transmission shaft (31), so that the mixed fertilizer powder is periodically supplied to the fertilizing conveying channel (17); meanwhile, each powder stirring rod (9) can move up and down periodically along the axial direction of the stirring shaft (25) while rotating along the axial direction of the stirring shaft (25), so that a spiral stirring effect is formed in the powder mixing and stirring cavity (5), and the fertilizer and powder in the powder mixing and stirring cavity (5) are mixed more uniformly.
