Embodiment Construction

[0018] The specific content and working process of the present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0019] The working process of precision agriculture automatic / manual variable fertilizer applicator based on virtual GPS: according to the needs, the cultivated land is divided into operation unit grids of appropriate size, and in each operation unit, based on the nutrient content information in the soil and crop demand, Fertilization decisions are made based on nutrient balance and expert knowledge, and prescription maps are generated. During the fertilization operation, by obtaining the working speed of the operating machine in real time and calculating the geographic location of the operating machine, the fertilization decision information is extracted according to the code of the operating unit where the fertilizer applicator is located and the corresponding speed of the stepping motor is output to...

Abstract

The invention provides a precise agricultural automatic / manual variable fertilizing machine based on a virtual GPS (global position system), which aims at applying fertilizers to soil according to the crop nutrition requirements through the virtual GPS under the circumstance that farmland nutrition space distribution is not uniform so as to achieve the purposes of reducing the input, increasing the benefit and improving the quality of agricultural products. The precise agricultural automatic / manual variable fertilizing machine comprises a virtual GPS navigation system and a variable deep fertilizing and precise sowing machine, wherein the virtual GPS navigation system is separated from the variable deep fertilizing and precise sowing machine and comprises a differential global position system (DGPS), a geographic information and field operation land parcel management system, a field operation land parcel grid identification and control program, and an IC (integrated circuit) card for storing land parcel management and variable fertilization decision information.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an automatic / manual variable fertilization machine for precision agriculture based on virtual GPS. technical background [0002] China is a large agricultural country, and the issues of agriculture, rural areas and farmers have always been major issues related to the overall modernization drive. In recent years, the extensive use of chemical fertilizers, pesticides and plastic films, as well as uncontrolled flood irrigation have caused serious agricultural ecological environmental problems. The soil organic matter is gradually depleted, water and fertility are poor, the soil structure is damaged, and soil erosion is serious. Therefore, seeking a development model suitable for today's society and developing modern agricultural technology has become an urgent problem to be solved in the development of modern agriculture in order to improve the agricultural ecological environment, increase...
