1) according to the minimum size c of the seeds determined in the first step, on the premise that the clearance of the brush wheel is not larger than the minimum size c of the seeds, the clearance of the brush wheel is determined;
2) according to the maximum size a of the seeds determined in the first step, on the premise that the minor axis and the major semi-axis of the ellipse of the seed guiding pipe are not smaller than the maximum size a of the seeds, the major axis of the U-shaped groove of the seed guiding pipe is 1.3a, and the minor axis is 0.9 a;
c, determining the water application amount, solute type and solution concentration according to the seed type and planting agronomic requirements;
1) determining the required water application amount z by using a formula z (y-x) dry soil mass according to the real-time soil water content x of a sowing area being 14%, and the soil water content y being 21% when seeds fall to the ground and do not bounce;
2) selecting a solute type according to the seed type and planting agronomic requirements;
3) diluting the solute to a desired concentration;
d, intermittently spraying liquid to the seed ditches during operation
1) And (4) filling the prepared solution in the third step into a water tank, using the water application amount as the amount of the spraying solution, and determining the opening degree of the electromagnetic valve during single liquid spraying according to the water application amount.
2) Adding the data of the opening degree of the electromagnetic valve determined in the step 1) into a single chip microcomputer, identifying the passing seeds by using a sensor, transmitting a seed signal to the single chip microcomputer, and after receiving the seed signal, the single chip microcomputer controls the opening and closing of the electromagnetic valve by outputting a PWM (pulse width modulation) signal in combination with the preset opening degree of the electromagnetic valve to complete the intermittent spraying of the soil liquid in the seed furrow.
