Embodiment Construction

[0063] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0064] The amount of sowing has a great influence on the yield and quality of crops; the amount of fertilization not only affects the yield and quality of crops, but also has an extremely important impact on the environment and water resources. The invention uses the detection technology based on the weighing method and the capacitance method and the feedback control technology using the motor, and according to the sowing and fertilization operation prescription map, realizes precise and small amount of sowing and precise fertilization according to the demand of land fertilizer, and realizes saving seeds and fertilizers On the basis of improving crop yield and quality while reducing environmental pollution.

[0065] see figure 1 , figure 1 It is a flow chart of the method of the present invention. The method for controlling...

Abstract

A method and a device for control of tillage-free seeding machine seeding quantity are used for control of the tillage-free seeding machine seeding quantity of fine and little amount seeding and precise fertilization according to earth fertilizer quantity. The method comprises the following steps: a loading numerical information of seeding machine operation areas; b variable seeding feedback; c acquiring real time position coordinate information; and d precisely controlling fertilization according to prescriptions. The device comprises an onboard computer installed on the seeding machine, onboard global positioning system (GPS) navigation system, a variable seeding feedback device and a precise fertilization control device. The numerical information of the seeding machine operation areas is loaded on the onboard computer, the GPS navigation system, the variable seeding feedback device and the precise fertilization control device are respectively connected with the onboard computer through an onboard signal processing circuit.

Description

technical field [0001] The invention relates to an online detection technology for agricultural machinery and equipment, in particular to a method and device for precisely controlling the seeding rate of a no-tillage seeder. Background technique [0002] Sowing is an important link in agricultural production and the basis for ensuring high yields and harvests. The technical problem to be solved is the precise control of the seeding rate of the no-tillage planter. For example, the precise control of the variable grain distance of corn on-demand can be realized, and single-grain and equidistant sowing can be realized. Precise sowing can save a lot of high-quality seeds. Sowing corn can save 2.5-3kg per mu; cotton can save 5kg; soybean can save 1.5kg; millet can save 0.31kg. Precision sowing can save the man-hours of thinning or completely eliminate the thinning process. The crop seedlings are uniform, uniform and strong, the seedlings are ventilated and light-transmitting, th...
