Problems solved by technology

The main disadvantages of the first method are that there are many operation steps and high cost, and the land preparation in autumn and spring will cause a large amount of soil moisture to be lost, which will aggravate the drought; the second is that it is difficult to return the straw safely to the field
The second method is the method of plowing into ridges after stubble removal and sowing on the ridges, which is an improved traditional cultivation technique. Its main disadvantages are that the plow layer is shallow (15-18cm), the bottom layer of the plow is thicker, and the soil moisture loss is serious when ridges are plowed in spring. Under the 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 human and animal power

Embodiment 1

[0026] In the first year, the current cultivation method is evenly ridged, and corn stalks with a height of 1, 30 cm are left in the autumn harvest to rot naturally, and rotary tillage is not carried out in autumn; Precisely sow corn between the rows to form a new corn seedling belt 2, and carry out narrow subsoiling in combination with topdressing in the stubble belt, with a width of 5 cm and a depth of 20 cm. During the autumn harvest, the corn stalks will continue to be high stubble 1, and the height will still be 30 cm. No rotary tillage in autumn, no soil preparation in spring of the third year, precision sowing of corn between the rows of the second year, and formation of new seedling belts, combined with topdressing in the stubble belt for narrow deep loosening, the width and depth are the same as those of the upper The same for one year, 30cm high stubble will be left in autumn harvest, and rotary tillage will not be done in autumn. This is repeated to complete the hig...

Embodiment 2

[0030] In the first year, the current cultivation method is evenly ridged, and corn stalks with a height of 1, 50 cm are left in the autumn harvest, and they are allowed to rot naturally, and rotary tillage is not carried out in autumn; Precisely sow corn between the rows to form a new corn seedling belt 2, and carry out narrow subsoiling in combination with topdressing in the stubble zone, with a width of 15 cm and a depth of 40 cm. During the autumn harvest, the corn stalks will continue to be high stubble 1, and the height will still be 50 cm. No rotary tillage in autumn, no soil preparation in spring of the third year, precision sowing of corn between the rows of the second year, and formation of new seedling belts, combined with topdressing in the stubble belt for narrow deep loosening, the width and depth are the same as those of the upper It is the same in one year, and the high stubble of 50 cm will continue to be left during autumn harvest, and rotary tillage will not ...

Embodiment 3

[0033] In the first year, the current cultivation method is evenly ridged, and corn stalks with a height of 1, 30 cm are left in the autumn harvest to rot naturally, and rotary tillage is not carried out in autumn; Precisely sow corn between the rows to form a new corn seedling belt 2, and carry out narrow subsoiling in combination with topdressing in the stubble zone, with a width of 5 cm and a depth of 20 cm. During autumn harvest, corn stalks should be left as high stubble 1, with a height of 50 cm. Rotary tillage is still not used, and the ground is not prepared in the spring of the third year. The corn is directly sown between the rows in the second year with precision, and a new seedling belt is formed. The width is 15 cm and the depth is 15 cm. 40cm, and 30cm high stubble will be left in autumn harvest, and rotary tillage will not be used in autumn. This is repeated to complete the high-stubble inter-row cultivation planting method of changing the position of the seedli...

Abstract

A method for cultivating corn with high yield includes such steps as harvesting corn and leaving high stubble in field for natural erosion without rotary cultivating for the first year, direct sowing, applying top application, harvesting and leaving high stubble in field without rotary cultivating for the second year, and so no.

Description

Technical field: [0001] The invention belongs to crop cultivation techniques, in particular to a corn cultivation method. Background technique: [0002] Among the existing farming and cultivation techniques, countries with developed economies and suitable climate conditions mostly adopt the cultivation methods of mechanical harvesting, straw crushing and returning to the field for mechanized cultivation. [0003] There are two main methods of cultivation and cultivation in my country: one is turning and harrowing and sowing into a 60-70cm uniform ridge; . The main disadvantages of the first method are that there are many operation steps and high cost, and the soil moisture will be lost in a large amount in autumn and spring, which will aggravate the drought; the second is that it is difficult to return the straw safely to the field. The second method is the method of plowing into ridges after stubble removal and sowing on the ridges, which is an improved traditional cultiva...
