[0002] In agricultural scientific research experiments, in order to better discover the rules, it is often necessary to make the growth of plants in different positions in the same seedbed as consistent as possible. Since the amount of organic fertilizer applied is a key factor affecting plant growth, in order to ensure the consistent growth of plants in different positions of the same seedbed, when spreading organic fertilizer on the experimental seedbed, it is necessary to ensure that the fertilization points are uniform and the amount of fertilizer at each fertilization point is consistent. However, in actual operation, there are often the following technical difficulties when spreading organic fertilizer on the seedbed: it is difficult for test personnel to accurately grasp and maintain the equidistant arrangement between each fertilization point. At the same time, it is also difficult to ensure that the amount of organic fertilizer applied at each fertilization point fully meets the preset standards. The resulting uneven fertilization and uncertainty will directly affect the nutrient supply of plants in the seedbed, and then cause significant differences in the growth of plants in different positions of the same seedbed, seriously affecting the accuracy of the test results.
