Embodiment Construction

[0036] The present invention provides a corn seed fertilizer simulcasting formula fertilizer applicator and fertilization method. The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0037] The fertilizer spreader includes a main beam, a driving mechanism, a seed box and a fertilizer box installed on the main beam, a seed shovel connected with the seed box, a fertilization pipe connected with the fertilizer box, a fertilization shovel connected with the fertilization pipe, and a seed row The pressure wheel on the lower part of the shovel and fertilizing shovel. Except for the fertilizer box and fertilizing shovel, the other structures of the fertilizer applicator are the same as those of the conventional corn seed fertilizer simulcaster, and only the different fertilizer boxes and fertilizing shovels are described in detail here.

[0038] The fertilizer box is composed of 4 sub-fertilizer box...

Abstract

The invention belongs to the technical field of agricultural fertilizer application and particularly relates to a corn seed manure simultaneous-application prescription fertilizer applicator and a fertilizer application method. A fertilizer box of the fertilizer applicator consists of secondary fertilizer boxes which are arranged side by side from front to back; each row of fertilizer outlets of the secondary fertilizer box respectively correspond to fertilizer application shoves; the bottom of each fertilizer application shovel is provided with a shallow-layer fertilizer outlet and a deep-layer fertilizer outlet which are arranged up and down; a shallow-layer fertilizer passage and a deep-layer fertilizer passage are arranged inside each fertilizer application shovel; each fertilizer outlet of the secondary fertilizer boxes is connected with each shallow-layer fertilizer passage or each deep-layer fertilizer passage; during fertilizer application, fertilizers are respectively fed into each secondary fertilizer box according to the requirements on shallow-layer fertilizer application and deep-layer fertilizer application by automatically making a prescription so as to realize layered composite fertilizer application. According to the required prescription of crops, the fertilizer application cost is effectively lowered, the utilization efficiency of nutrients is improved and ecological environment is protected; fertilizer application is flexibly performed according to the prescription and is not limited by agricultural acreage; the fertilizer application method is high in flexibility and high in multiplicity with a soil measurement prescription.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilization, and in particular relates to a corn seed fertilizer simultaneous sowing formula fertilizer applicator and a fertilization method. Background technique [0002] my country's soil testing and formula fertilization project has been carried out for more than ten years, and the net increase of compound fertilizers in my country accounts for 68% of the net increase of chemical fertilizers. There are more than 3,000 compound (mixed) fertilizer enterprises in the country, and the average output of the enterprises is less than 10,000 tons; the product quality is uneven. Compound (mixed) fertilizer is produced by three kinds of simple fertilizers of nitrogen, phosphorus and potassium through various processes, and the price is 29% higher than the average price of simple fertilizers with equal nutrients. A large number of survey data show that compound (mixed) fertilizer expenditure acco...
