Problems solved by technology

The mature harvest of rapeseed in the Yangtze River Basin is generally in mid-May, and the mature harvest of wheat is generally in late May. Transplanting cotton after wheat (oil) or direct-seeding cotton after wheat (oil) is more than 20 days later than conventional interplanting cotton. The effective flowering and bolling period of cotton is shortened, and the yield and quality of cotton are reduced to varying degrees.

Embodiment 1

[0026] Embodiment 1 (No. 1 test field):

[0027] Step 1: Planting method design: On October 25, 2016, after the cotton was harvested, the wheat was sown in a drill. On April 20, 2017, the wheat entered the late stage of milk ripening and began to mechanically harvest the baled coated silage, and transplanted cotton On April 10, 2017, the nutrient bowl was used to cover the seedlings with double film, and when the silage wheat was mechanically harvested, the stubble was transplanted;

[0028] Step 2: Wheat variety and seeding rate: The variety is suitable for the local climate, with strong adaptability, thick stems, moderate plant height, and strong tillering ability. The wheat variety is Zhengmai 9023.

[0029] Step 3: Fertilize wheat: on March 10, every 667m 2 Apply 15kg of compound fertilizer;

[0030] Step 4: Cotton variety selection: the transplanted cotton selects Zhongmian 1279, a high-quality hybrid cotton variety that has passed the examination and is suitable for pl...

Embodiment 2

[0036] Embodiment 2 (No. 2 test field):

[0037] Step 1: Planting method design: On November 5, 2016, after the cotton was harvested, the wheat was sown in full width. On May 5, 2017, the wheat entered the late stage of milk ripening and began to mechanically harvest the baled coated silage; Cotton was planted on April 20 with nutrient bowls and double-film covering seedlings, and the stubble was transplanted after the silage wheat was mechanically harvested;

[0038] Step 2: Wheat variety and seeding rate: The variety is selected as a medium-early-maturing variety suitable for the local climate, with strong adaptability, strong stem, moderate plant height, and strong tillering ability. The wheat variety is Emai 23.

[0039] Step 3: Fertilize wheat: on March 20, every 667m 2 Apply 8-10kg urea;

[0040] Step 4: Cotton variety selection: the transplanted cotton selects Zhongmian 1279, a high-quality hybrid cotton variety that has passed the examination and is suitable for planti...

Embodiment 3

[0046] Embodiment 3 (No. 3 test field):

[0047] Step 1: Planting method design: On October 25, 2016, after the cotton was harvested, the wheat was sown in a drill; on April 28, 2017, the wheat entered the late stage of milk ripening and began to mechanically harvest the baled coated silage; After the silage wheat is mechanically harvested, it is rotary tilled, and the cotton sowing and fertilizing machine is used for sowing after the soil is settled;

[0048] Step 2: Wheat variety and seeding rate: The variety is selected as a medium-early-maturing variety suitable for the local climate, with strong adaptability, strong stem, moderate plant height, and strong tillering ability. The wheat variety is Emai 23.

[0049] Step 3: Fertilize wheat: on March 22, every 667m 2 Apply 15kg of compound fertilizer;

[0050] Step 4: Cotton variety selection: the early-maturing variety CN01 is selected for direct-seeding cotton;

[0051] Step 5: Cotton sowing: according to the planting met...

Abstract

The invention provides a labor-lightened and simplified high-yield and highly-efficient planting mode for a cotton field. The planting mode provided by the invention adopts two different planting manners of transplanting or direct sowing of cotton, and further defines the variety selection and sowing amount of wheat (rape), fertilizer application to the wheat (the rape), variety selection of the cotton, sowing and seedling-raising of the cotton, fertilizer application and weeding in the cotton field, planting density of the cotton, chemical adjustment, and disease and pest control. According to the invention, a traditional planting mode of wheat (rape) and cotton continuous cropping is changed, so problems of decreased yield and quality of the cotton due to shortened effective flowering and boll-setting periods of the cotton are solved; whole-crop wheat (rape) is used as a source of green fodder and has high forage nutritive value, so development of a silage wheat (rape)-cotton continuous cropping mode has far-reaching significance on promotion of development of animal husbandry, improvement of profits of the cotton field and promotion of income increase of cotton farmers; meanwhile, the yield and quality of the cotton are greatly improved, and conservation of labor is saved.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a light, simplified, high-yield and high-efficiency planting mode for cotton fields. Background technique [0002] Cotton is an important economic crop and raw material for textile industry in my country. Double cropping of wheat (oil) and cotton is one of the main planting patterns in the cotton region of the Yangtze River Basin. In order to meet the needs of mechanized production, the traditional wheat (oil) cotton interplanting planting pattern has gradually been changed to wheat (oil) cotton continuous cropping planting pattern. The mature harvest of rapeseed in the Yangtze River Basin is generally in mid-May, and the mature harvest of wheat is generally in late May. Transplanting cotton after wheat (oil) or direct-seeding cotton after wheat (oil) is more than 20 days later than conventional interplanting cotton. As a result, the effective flowering and boll se...
