Problems solved by technology

Cotton production using traditional production methods is mainly concentrated in sowing and harvesting, of which manual harvesting accounts for about 70% of the total labor, resulting in a decline in the income of cotton farmers, a decrease in their willingness to plant, and the dilemma of competition for land for grain and cotton, especially in the Yangtze River Basin. The reduction in area is even greater

Embodiment 1

[0041] In 2018, in the demonstration field of Gong'an County, Hubei Province, the intercropping method of machine-picked cotton and upland rice was divided into different areas.

[0042] Cotton variety: Crystal Cotton 116

[0043] Upland rice variety: Hanyou 73

[0044] (1) Rotary tillage and land preparation: Mechanical rotary tillage opens the box to form ridges, the boxes and ridges are spaced in turn, the ridge height is 10-15cm, the ridge width is 76-85cm, and the box width is 220-230cm.

[0045] (2) Apply base fertilizer: spread the three-component compound fertilizer in the upland rice planting area of ​​the box area, and the amount of application is 60kg / mu in terms of the area of ​​the box area; in the cotton planting area of ​​the ridge area, the three-element compound fertilizer is sown together with the seeds.

[0046] (3) Sowing at the same time: In the middle of each ridge, use a cotton sowing and fertilization integrated machine precision machine to sow cotton se...

Embodiment 2

[0076] In 2019, in the demonstration field of Gong'an County, Hubei Province, the intercropping method of machine-picked cotton and upland rice was divided into different areas.

[0077] Cotton Variety: EZ9

[0078] Upland rice variety: Hanyou 73

[0079] (1) Rotary tillage land preparation: Mechanical rotary tillage opens the box to form ridges, the boxes and ridges are spaced in turn, the ridge height is 10-15cm, the ridge width is 90-100cm, and the box width is 290-300cm.

[0080] (2) Applying base fertilizer: Sprinkle three-component compound fertilizer in the upland rice planting area of ​​the box area, and the amount of application is 50kg / mu based on the area of ​​the box area. In the cotton planting area in the ridge area, the ternary compound fertilizer is sown together with the seeds.

[0081] (3) Sowing at the same time: In the middle of each ridge, use a cotton sowing and fertilization integrated machine precision machine to sow cotton seeds in the ridge area. In...

Embodiment 3

[0111] In Gong'an County, Hubei Province in 2020

[0112] Cotton varieties: Zhong 425, ZD2040

[0113] Upland rice variety: Hanyou 73

[0114] (1) Rotary tillage and land preparation: Mechanical rotary tillage opens the box to form ridges, the boxes and ridges are spaced in turn, the ridge height is 10-15cm, the ridge width is 80-90cm, and the box width is 240-250cm.

[0115] (2) Applying base fertilizer: Sprinkle three-component compound fertilizer in the upland rice planting area of ​​the box area, and the amount of application is 70kg / mu based on the area of ​​the box area. In the cotton planting area in the ridge area, the ternary compound fertilizer is sown together with the seeds.

[0116] (3) Sowing in the same period: In the middle of each ridge, use a cotton sowing and fertilization integrated machine precision machine to sow cotton seeds in the ridge area. In terms of the area of ​​the ridge area, the cotton seeding rate is 1kg / mu, and the amount of three-component...

Abstract

The invention discloses a machine-harvested cotton and upland rice intercropping zoned irrigation cultivation method, and relates to the technical field of agricultural planting. The machine-harvested cotton and upland rice intercropping zoned irrigation cultivation method comprises the following steps that (1), rotary tillage and soil preparation are carried out; (2), intercropping and sowing are carried out in the same period; (3), irrigation is carried out in different areas; and (4), harvesting is carried out. According to the machine-harvested cotton and upland rice intercropping zoned irrigation cultivation method, water-saving measures are adopted for regional irrigation according to the remarkable difference between the water demand of cotton and the water demand of upland rice, only the upland rice region needs to be irrigated, the cotton region does not need to be specially irrigated, the water resource utilization rate and irrigation efficiency can be improved through regional irrigation, different crops can adapt to water stress, so that crop growth is promoted, and the yield of cotton and upland rice is improved. Light and simplified technologies such as unmanned aerial vehicle aerial seeding, precision mechanical seeding and mechanical harvesting are adopted, the problems that a traditional intercropping mode is large in labor investment, high in cost and low in cotton field benefit can be solved, and the machine-harvested cotton and upland rice intercropping zoned irrigation cultivation method is very suitable for being popularized in the Yangtze river basin.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, and more specifically relates to a partition irrigation cultivation method for machine-picked cotton and upland rice intercropping. Background technique [0002] Cotton is a traditional dominant crop in the Yangtze River Basin. Taking Hubei Province as an example, the planting area has been stable at 5-7 million mu in recent decades, and the total output of lint cotton is about 400-500 thousand tons. The planting area and output are second only to Xinjiang, Shandong, and Hebei, ranking fourth in the country and ranking first in the cotton area in the Yangtze River Basin. [0003] In recent years, the cotton planting area has shown a cliff-like decline. Taking Hubei Province as an example, the cotton area has continued to decline since 2013, especially in 2014 and 2015. It has dropped from 7.09 million mu in 2012 to the current 2.389 million Mu, the total output dropped from 531,500...
