Problems solved by technology

[0003] The existing bare land planting method in southern Xinjiang has a low cotton yield when used in field production. For example, in the "Experiment on Sowing Date and Density of Bare Land Cultivation of Early-maturing Cotton in Southern Xinjiang", the cotton seed cotton yield is less than 4000kg·hm -2 , the output needs to be further increased

Embodiment 1

[0041] The three experimental sites are located at the Alar Comprehensive Experimental Station of the National Cotton Industry Technology System, the Tumushuk Yarkand River Comprehensive Experimental Station, and the Korla Kongque River Comprehensive Experimental Station. The Agricultural Science Research Institute of the Third Division of the Corps and the experimental field of the Xinjiang Bazhou Agricultural Science Institute.

[0042] The tested varieties were the short-season cotton early-maturing variety Zhongmian 619 provided by the Early-maturing Research Group of the Cotton Research Institute of the Chinese Academy of Agricultural Sciences, and the early-maturing cotton variety Xinluzao 48 introduced from northern Xinjiang. The test plot was repeated three times, with a total of 6 plots. Each plot had two sowing widths of 36 rows, a row length of 50m, a plot area of ​​1 mu, and a planting density of 252,000 plants·hm -2 . Other production conditions are the same as f...

Embodiment 2

[0082] Daejeon of Tumu Shuke, the test point. The tested varieties are Zhongmian 619 and Xinluzao 48. Each address is planted with 10 mu of each variety, and the planting density is set to 240,000 plants·hm -2 . Other production conditions are the same as field production.

[0083] 1. Specific steps of the test

[0084] 1.1 Land preparation

[0085] The test field is irrigated in winter and spring, the soil is loamy, the soil salt content is less than or equal to 3g / Kg, and the base fertilizer is applied to the plowed field (three materials phosphorus 58kg hm -2 , urea 145kg·hm -2 , Potassium sulfate 220kg·hm -2 , organic fertilizer 2800kg·hm -2 right). Fine ground preparation.

[0086] 1.2 Seed treatment

[0087] Seed drying, artificial seed selection, and seed dressing with seed coating agent.

[0088] 1.3 sowing date

[0089] Test the moisture content of the soil (volume moisture content within the range of 15% to 25%) and sow seeds. When the moisture content is ...

Embodiment 3

[0109] Daejeon in Aral, the experimental point. The tested varieties are Zhongmian 619 and Xinluzao 48. Each address is planted with 10 mu of each variety, and the planting density is set at 255,000 plants·hm -2 . Other production conditions are the same as field production.

[0110] 1. Specific steps of the test

[0111] 1.1 Land preparation

[0112] The test field is irrigated in winter and spring, the soil is loamy, the soil salinity is ≤3g / Kg, and the base fertilizer (three-material phosphorus 85kg hm -2 , Urea 155kg·hm -2 , Potassium sulfate 230kg·hm -2 , organic fertilizer 3200kg·hm -2 right). Fine ground preparation.

Abstract

The invention relates to a method for cultivating film-free cotton in southern Xinjiang, comprising the following steps: selecting an extra-early-maturing upland cotton variety of less than 120 days under film-covering cultivation conditions and 135-140 days under film-free cultivation conditions; 240000‑255000 plants﹑ hm ‑2 ; When the cotyledon is flattened, the chemical adjustment is started twice continuously, and the dosage of mepipebine is 1.4-1.6, 0.8-1.2g. hm ‑2 , after topping, the amount of benzedramine is 4.3-4.8g. hm ‑2 ; Water and fertilizer management and pest and weed control during the growth period. The cultivation method no longer covers the plastic film, which prevents the white pollution caused by the plastic film. The present invention selects a specific early-maturing cotton variety, and by adding an appropriate amount of base fertilizer and supplemented by chemical adjustment and water and fertilizer management, it provides sufficient water for the growth period of cotton at each stage. Nutritional components, the cultivated cotton overcomes the late-maturing reduction in yield and quality caused by late sowing, and the yield and quality are steadily improved.

Description

technical field [0001] The invention relates to the field of cotton planting, in particular to a method for cultivating filmless cotton in southern Xinjiang. Background technique [0002] Since the promotion of plastic film cotton planting technology in Xinjiang in the 1980s, the problem of plastic film residual pollution has become increasingly serious. The cost of manually uncovering the film in cotton fields in southern Xinjiang accounts for 25% of the labor management cost. Even if manual film removal or mechanized recycling is used, the annual residual rate of plastic film in the soil is still about 15%. In some cotton fields without film removal, the plastic film residual rate is as high as 100%. The average annual plastic film residual rate in Xinjiang is 24.4%, which is harmful to the soil environment Pollution has become one of the worst in the country. According to Mao Shuchun's 2014 "China Cotton Prosperity Report", the machine-picked cotton planting production ...
