Problems solved by technology

The main disadvantages of these two methods are that there are many operation links and high cost. Most of the stubble removal does not form ridges at the same time, or the ridges are not suppressed. Drought; and it is difficult to safely return straw to the field. Under the current condition of no fertilizer application, it is still a predatory planting method
During mechanical operations, the field is rolled too many times, the soil bulk density increases, the ability to resist natural disasters is low, and the yield is not high and unstable
The labor intensity is high and the labor productivity is low when working with animal power

Embodiment 1

[0014] The present invention is an improvement of a method of corn plowing and land preparation. In the first year, 20 cm of high stubble is left when harvesting corn planted on uniform ridges (ridge distance 65 cm), and the soil is prepared in autumn. The high stubble is eliminated with a general-purpose stubble remover, and at the same time, ridges are suppressed. After reaching the sowing state, the broken stubble will rot naturally in the soil and return to the field; instead of performing soil preparation in the second spring, precision seeding will be carried out directly on the ridge formed by the first year's soil preparation, and intertillage will be carried out between rows during the topdressing period (depth 18cm). 20cm high stubble is still left in the autumn harvest, and the high stubble is eliminated in the autumn to form a ridge; the third spring still does not prepare the ground, and directly sows corn between the rows in the second year, and intertills between ...

Embodiment 2

[0018] In the first year, 30 cm of high stubble was left when harvesting the corn planted on an even ridge (ridge distance 60 cm), and the autumn soil preparation was carried out to eliminate the high stubble. Do not prepare the soil in the spring of the first year, but directly carry out precision sowing on the ridge formed by the soil preparation in the first year. During the topdressing period, perform intertillage between the rows (depth 20cm), leave 20cm high stubble in the autumn harvest, and carry out autumn soil preparation to eliminate the high stubble and form a ridge In the spring of the third year, still do not prepare the land and directly sow corn with precision between the rows in the second year, carry out intertillage (depth 25cm) between the rows during the topdressing period, leave a high stubble of 30cm during the autumn harvest, and carry out the autumn soil preparation to eliminate the high stubble and form a ridge; The cultivation is repeated between year...

Embodiment 3

[0021] The present invention is an improvement of a method of corn plowing and land preparation. In the first year, 30 cm of high stubble is left when harvesting corn planted on uniform ridges (row distance of 70 cm), and the soil is prepared in autumn. When the sowing state is reached, the broken stubble will naturally rot in the soil and return to the field; in the spring of the second year, the soil preparation will not be carried out, but the precision seeding will be carried out directly on the ridge formed by the soil preparation in the first year, and inter-tillage between rows (depth 25cm) will be carried out during the topdressing period. In the autumn harvest, the high stubble was still 30cm, and the high stubble was removed in autumn to form a ridge; in the spring of the third year, the corn was sown between the rows in the second year without soil preparation, and intertillage was carried out between the rows (depth 25cm) during the topdressing period, and the autumn...

Abstract

The present invention provides method for tilling corn land, and features that high stubble is left while harvesting corn, stubble is cleared and ridge in seeding state is formed in the autumn, the land is not further tilled before seeding in the next spring, and intertillage is completed during top dressing, with the said process being repeated year after year. The said tilling method, compared with available tillage method, has organic matter in the surface soil increased by 0.30-0.80 g / kg, soil water content in spring raised by 0.5-2.0 % and corn yield raised by 5-10 %.

Description

technical field [0001] The invention belongs to crop farming technology, in particular to a corn protective tillage method. Background technique [0002] In the existing farming and cultivation, in countries with developed economy and suitable climatic conditions, all agricultural production has been mechanized, agricultural machinery and agronomy are combined, and the key technologies required by agronomy are realized through agricultural machinery. [0003] The current soil preparation methods in Northeast my country: the first is to harvest corn stalks in autumn, turn and harrow them to form an even ridge of 60-70 cm; The main disadvantages of these two methods are that there are many operation links and high cost. Most of the stubble removal does not form ridges at the same time, or the ridges are not suppressed. In addition, it is difficult to safely return straw to the field. Under the current conditions of no fertilizer application, it is still a predatory planting m...
