Embodiment Construction

[0017] After the soil fertilization prescription is determined according to the soil information of the fertilization plot, the prescription map is input into the AgGPS170 computer 3 in the file format of . Then obtain the GPS differential signal (DGPS signal). The system software will determine the geographical location of the fertilization machine in the field according to the obtained differential signal. The navigation software installed on the AgGPS170 computer and the position coordinates of the fertilization prescription map match each other. If the coordinates of the two match each other, the computer passes The data switch 2 transmits the information on the amount of fertilization at this position to the fertilization controller 6, and the controller controls the hydraulic motor assembly 13. By adjusting the opening of the control valve to adjust the oil supply, the speed of the hydraulic motor is adjusted. The motor drives the intermediate transmission shaft 14, and ...

Abstract

The present invention utilizes tractor and mounted fertilizer applicator, and utilizes the GPS positioning system and computer which are fixed on the tractor and used as mechanical control system to provide the information about amount of chemical fertilizer to be applied in defined position and utilizes the regulation of rotating speed of fertilizer-discharging wheel so as to attain the goal of regulating fertilizer-applied amount. Said invention can raise utilization rate of fertilizer by 40-50%, and can raise yield by 30%.

Description

technical field [0001] The invention belongs to agricultural machinery fertilization machinery Background technique [0002] As a source of nutrients for plant growth, chemical fertilizers are widely welcomed by farmers from all over the world. Farmers around the world generally use chemical fertilizers as one of the main means of increasing food production. Usually, farmers use chemical fertilizers by spreading them evenly on the ground and then carrying out corresponding agronomic operations. In this way, the same amount of chemical fertilizers are still used in places with high soil nutrients and places with low soil nutrients. Some of these excessive fertilizers are decomposed in the soil, and some of them are leached in the soil. These leached fertilizers are absorbed by groundwater, causing groundwater pollution and affecting people's health. Therefore, with the growing call for sustainable development of agricultural production, the environmental pollution caused by ...
