Abstract.

. The monitoring of the amount of sowing and fertilizer as well as the depths of sowing is one of the important research of the machine of precision sowing and fertilizing of wheat. The existing research focuses on the implements of single-grain sowing, such as single-corn sowing, but there are few studies on the monitoring of wheat-sowing quantities, fertilizer quantities and sowing depths. However, it is of great significance to achieve the real-time monitoring and to find superior conditions of planting with appropriate amount of seeds, suitable depths and minimum fertiliser, which can reduce costs and pollution to the ecological environment to establish a sustainable and high-yield planting model. This article firstly gives an overview of the current monitoring techniques of sowing amount, fertilizer amount and sowing depths and then proposes both new monitoring methods and a scheme of monitoring.
