Embodiment Construction

[0060] The method of returning whole stalks and whole stalks of the present invention to the furrow sowing of corn with full film and double ridges will be described in detail below through specific examples.

[0061] (1) Ridging by pressure bar: After evenly fertilizing (the fertilization rate is 40-80 kg / mu) in the inter-ridge ditch of the corn plot planted with full-film double-furrows in the previous stubble, the corn straw returning machine is used to return the corn straw to the field. The whole stalk of straw is overwhelmed in the ditch between the ridges, and shaped according to the parameters of 60-65 cm wide and 10-15 cm high to form a ridge piled up by straw;

[0062] (2) Ridging and mulching: Use the ridge-forming and mulching machine to turn over the soil at the ridge of the previous crop, and complete a 5-10 cm soil covering layer on the ridge where the straw is piled up, and finally form a width of 70-80 cm. , A ridge with a height of 15-25 cm (the ridge formed ...

Abstract

The invention provides a full-film dual-ridge integral-straw-returning corn furrow sowing method. The full-film dual-ridge integral-straw-returning corn furrow sowing method achieves straw returning and completes turnover, ridging and mulching after harvesting in the prior art, and accordingly biological organic matter in whole quantity can be returned to soil, zero bareness of the land can be achieved, and further, soil organic matter content is increased effectively, evaporation of moisture in the soil is blocked off completely, rainfall is retained in the soil completely, and soil organic matter content increase and rainfall utilization efficiency improvement are achieved synchronously. Processes such as returning of integral straws into the fields, turnover, ridging and mulching are completed at a time, a process that straw returning after straw smashing in the prior art is omitted, and accordingly labor force is reduced, and production cost is lowered. In a word, the straw returning and full-film dual-ridge furrow sowing technology is adopted in dry farming corn planting areas in Gansu province, and the method provides a direction for guaranteeing steady production increase of corns in Gansu province and promoting sustainable development of the full-film dual-ridge corn furrow sowing technology.

Description

technical field [0001] The invention relates to a method for sowing corn, in particular to a method for sowing corn in furrows with full-film double ridges and whole stalks returning to the field. technical background [0002] my country produces 600-700 million tons of various crop straws annually, only about a quarter of which is returned to the field, and some remaining straws are piled up beside the fields or burned on the spot, which not only wastes resources but also pollutes the environment. At present, the content of soil organic matter is decreasing year by year. The average soil organic matter content in my country is only 1.5%, which is less than half of the average soil organic matter content in the United States. Straw returning to the field is an effective means to improve soil organic matter, and it is also an important part of saving costs and increasing efficiency, and developing quality-benefit agriculture. In recent years, Gansu Province has vigorous...
