Embodiment Construction

[0025] like Figure 1-12 As shown, the automatic corn seed combined planter of the present embodiment includes a trailer frame 13 connected by a universal joint, and a ground turning device 15, a fertilizing device 17, a seeding device, and a dripping device that are sequentially arranged on the trailer frame 13 18. Covering device 19;

[0026] Tilling device 15, used for raking, ridging and pitting cornfields;

[0027] Fertilization device 17, for carrying out pre-fertilization at the pit place;

[0028] Seeding device for sowing at the pit; may be a conventional seeder.

[0029] Drip device 18, for watering and / or applying water and fertilizer at the point pit;

[0030] The soil covering device 19 is used to cover the soil at the point pit. Thereby enabling joint operations on corn seeds.

[0031] The earth turning device 15 is connected with a sieve soil sending device 14, which is used to send the prefabricated soil to the ridging place; thereby realizing soil cultiva...

Abstract

The invention relates to a method for sowing corn seeds in contaminated soil after backfilling. The method for sowing the corn seeds in the contaminated soil after backfilling is characterized by comprising the following steps of: firstly, scribing and ditching a land, and excavating out soil in a delimited area through an excavator; secondly, laying a side isolation layer and a bottom isolation layer in the area where the soil is excavated; thirdly, sequentially backfilling heavy metal soil (1), a waste building material layer (2) and waste oil liquid soil (3); fourthly, backfilling the waste oil liquid soil (3) to form a soil covering layer (4) after fermenting the excavated soil; finally, carrying out harrowing, soil screening, ridging and ploughing on the soil covering layer (4) to form a ridge soil layer (5) and an inter-ridge groove (6) and carrying out pit digging, fertilization, sowing, watering and soil covering.

Description

technical field [0001] The invention relates to a method for sowing corn seeds in polluted soil after backfilling. Background technique [0002] Corn is a crop with a relatively wide planting area. There are many ways to sow corn. Among them, the sowing method that maximizes the yield of corn is to sow seed and fertilizer at the same time, and spread the fertilizer 10-15 cm below the corn seed. The best, and secondly, the double-row staggered planting form of corn can further increase the yield of corn. But existing planter all can't satisfy the optimum requirement of above-mentioned corn seeding, and Chinese Patent No. is that CN107046877A has announced a kind of corn sowing and fertilizing machine, comprises frame, seed fertilizer box, seed metering device, fertilizer device, seed metering device. Fertilizer discharge drive mechanism, seed and fertilizer discharge drive mechanism, notched disc, bearing seat I, bracket, double disc ditching seeding and fertilization mechan...
