Furthermore, the cultivation control system also comprises a key board and an alarm, and the key board and the alarm are in signal connection with the microprocessor. The key board is provided with a shutdown key, a data input key and a function selection key, and the alarm is a buzzer. In this embodiment, the battery, the microprocessor, the key board 2, the alarm 3, and the display 4 may be installed in one installation box 1, the key board 2 and the display 4 may be installed on the surface of the installation box, and the alarm 3 may be embedded on the outer side wall of the installation box 1.

The working principle of the cultivation control system is explained in detail as follows:

when normally calculating the total amount of ploughing, install the encoder on the shaft of press wheel, the press wheel also rotates a week when rotating 1 week, and the power shaft of fertilizer distributor also rotates a week with the power shaft of seeder in step simultaneously. Assuming that the width of the cultivating device is 2.5 meters, the circumference of the press wheel is 1.4 meters, the fertilizing amount of a circle of rotation of the power shaft of the fertilizer applicator is 0.5kg, and the seeding amount of a circle of rotation of the power shaft of the seeder is 25 grains. The parameters are input into the microprocessor through the key board and stored.

For example, when a certain land is cultivated, the press wheel rotates 500 circles. The area of 1 mu of land is 667m². The cultivation area of the cultivation device is 500 × 2.5 × 1.4/667 ═ 2.6235 mu; the fertilizing amount per mu is 500 x 0.5/2.6235 ═ 95.29 kg; the fertilizing amount per mu is 500 × 25/2.6235 ═ 4764 grains.
