Problems solved by technology

The traditional intercropping mode (double three zero, double two five) is mostly the mainstream mode under the background of small-scale peasant economy. This mode mostly relies on manual planting, which is labor-intensive, low economic benefit and not conducive to the development of mechanization, which seriously restricts the development of mechanization. The progress of agricultural mechanization in this area has dampened farmers' enthusiasm for farming
As a result, a large number of laborers choose to go out to work and give up agricultural planting, leaving a large amount of land unused, resulting in a waste of land resources, which seriously restricts the development of regional agriculture

Embodiment 1

[0032] A kind of novel intercropping strip planting method of the present embodiment, concrete steps are as follows:

[0033] S1. In that year, winter wheat was intercropped with spring corn. The width of intercropped winter wheat and spring corn was both 2m. Winter wheat was planted in 10 rows. In the next year, spring corn was planted in another blank zone, and spring corn was planted in 4 rows. One row per two rows, width 60cm, the row spacing between two rows within the width is 40cm, and the planting of winter wheat and spring corn is carried out by mechanical devices;

[0034] S2. After the winter wheat is harvested, use a mechanical device to plant summer corn in the planting belt, and plant 2 rows of summer corn with a row spacing of 40cm;

[0035] S3. After the summer corn is harvested, use mechanical devices to plow the land, and then rotate the two crops to plant winter wheat and spring corn, so as to realize the rotation of crops and balance soil nutrients.

Embodiment 2

[0037] This embodiment is optimized on the basis of the above-mentioned embodiment 1. A new type of intercropping strip planting method in this embodiment, the specific steps of step S1 in the above-mentioned embodiment 1 are as follows:

[0038] (1.1) Use land machinery and equipment to plow the planting land to remove weeds and sundries in the planting land;

[0039] (1.2) Divide the planting land into several planting belts with a width of 2m, divide the planting belts into wheat planting belts and corn planting belts, and cross the wheat planting belts and corn planting belts;

[0040] (1.3) Select winter wheat varieties suitable for planting according to the climate characteristics of the region, select winter wheat seeds with full grains, and plant 10 rows of winter wheat at equal row spacing in the wheat planting belt in autumn of that year;

[0041] (1.4) After sowing, spray herbicides and pesticides in closed mode to control the growth of weeds and damage seedlings ca...

Embodiment 3

[0047] This embodiment is optimized on the basis of the above-mentioned embodiment 2. A new type of intercropping strip planting method in this embodiment, the specific steps of step S2 in the above-mentioned embodiment 2 are as follows:

[0048] (2.1) After the winter wheat is harvested, according to the characteristics of the ecological environment in the area, select summer maize varieties suitable for planting, select summer maize seeds with full grains, no moths, and no mildew, and use large tractors to plant 2 rows of summer maize in the planting belt. For corn, the row spacing is 40cm, 80cm is left on both sides of the planting zonule, the hole spacing is 20cm, and 2 plants are fixed in each hole;

[0049] (2.2) Provide enough water during the critical critical period of summer maize water demand to ensure the water needed for summer maize growth, timely weeding, pest control and disease prevention;

[0050] (2.3) After the summer corn matures, harvesting, threshing and...

Abstract

The invention belongs to the technical field of planting methods, and relates to a novel intercropping strip planting method. According to the planting method, a planting zone is divided into wheat planting zones and corn planting zones, the area ratio of the two kinds of zones is 1:1, that is, winter wheat and spring corn are planted in the zones alternately, the wheat planting zones are used forplanting winter wheat and summer corn, and the corn planting zones are used for planting spring corn. When the winter wheat is harvested, the summer corn is immediately planted in the corresponding planting zones, winter wheat is planted in the spring corn zone after the summer corn is harvested, and planting is carried out on the planting zones in turn according to a planting sequence. Accordingto the novel intercropping strip planting method, mechanical operation can be realized in the planting and harvesting processes, large-scale development is facilitated, the process of the agricultural modernization in a region is promoted, labor and time are saved, manpower is saved, and the cost is reduced. According to the novel intercropping strip planting method, wheat and corn are planted inthe zones at intervals, so that land resources are fully utilized, and the yield of corn and wheat is improved.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation methods, and in particular relates to a planting method, in particular to a novel intercropping band planting method. Background technique [0002] Southwest China is mostly hilly landform, and the cropping system is dominated by multi-cropping intercropping. Intercropping plays an important role in ensuring food security by increasing the multiple cropping index. The three-cropping system of wheat / corn / sweet potato, wheat / corn / soybean, wheat / sorghum / soybean is the main planting mode in this area. The traditional intercropping mode (double three zero, double two five) is mostly the mainstream mode under the background of small-scale peasant economy. This mode mostly relies on manual planting, which is labor-intensive, low economic benefit and not conducive to the development of mechanization, which seriously restricts the development of mechanization. The progress of agricultural mechani...
