How To Scale Up The Development Of Cotton In Mengxi County?

< p > a few days ago, the Dun Xian farm in Ejinaqi Dongfeng Town, Alxa League, the Inner Mongolia Autonomous Region, has already been covered with big white flowers on the cotton plant.

Xinjiang Guiyang self propelled cotton picker and John Deal 7760 type self propelled cotton harvester are advancing rapidly in large fields, where cotton wool is picked up and leaves are left behind.

< p > Yu Shuxun, chief scientist of the Chinese Academy of engineering and the national cotton industry technology system, told reporters that the western part of Inner Mongolia is a typical temperate continental monsoon climate. Similar to the ecological conditions in northern Xinjiang, the advantages of planting cotton are outstanding.

There are abundant resources of light and heat, annual sunshine hours more than 3000 hours, drought and rain, evaporation, cotton pests and diseases, and cotton quality. Mengxi has a large area of saline alkaline dry land. Cotton is a drought resistant and salt tolerant crop. It can be cultivated for several years, and it can also improve soil.

< /p >

< p > natural condition is so superior. Why did the cotton in West Mengxi not develop greatly? "The key is that large-scale mechanized planting and harvesting problems have not been conquered."

Zhang Jianzhong, chief agronomist of Inner Mongolia Academy of agriculture and animal husbandry, said that unlike corn and wheat, cotton wool is light, and can not be harvested and used to obtain cotton batting by gravity separation.

The development of mechanic harvesting technology for cotton has provided convenient conditions for the large-scale development of cotton cultivation in Inner Mongolia.

< /p >

< p > in addition, "there are many people in Inner Mongolia, such as Ejinaqi, which has an area of about 115 thousand square kilometers, with a population of only 20 thousand.

At present, the purchase price of 1 kg seed cotton is about 8 yuan in the market, but the labor cost of collecting 1 kg seed cotton is close to 3 yuan, and the cost is too high.

Zhang Jianzhong said.

< /p >

< p > Yu Shuxun said that the Cotton Research Institute of Chinese Academy of Agricultural Sciences has developed the planting mode and its mechanized cultivation techniques according to the characteristics of machine picked cotton.

If the plant is "short", the bell is "dense", "early", the height of the cotton plant is relatively uniform, the plant spacing is 9 cm, and the strip planting is conducive to mechanized planting and harvesting.

< /p >

< p > it is reported that in 2011, the national cotton industry technology system established the Inner Mongolia cotton comprehensive test station relying on the Inner Mongolia Academy of agriculture and animal husbandry. In the past 3 years, the experimental station has introduced more than 90 varieties of cotton 50 and so on, screened out 8 main varieties suitable for planting in Inner Mongolia, and formed 10 key technologies, such as drip irrigation under mulch, drought and water conservation, integrated pest control, whole mechanization and light simplified planting.

In the national cotton production activities, Alashan Left Banner in 2011 was awarded a high yield record of 523.4 kg seed cotton per mu.

< /p >

< p > Li Xin, chairman of Gansu Huida trust and Trade Group Co., Ltd. in Ejinaqi, Inner Mongolia, said that because of the mechanization problem, the cotton planting and mining area of Mengxi has expanded rapidly.

In 2012, the cotton picking area of Alxa League was more than 300 mu, which has increased to more than 8000 mu this year. Next year, the cotton picking area in Inner Mongolia will be further developed.

< p > < strong > mechanized and large-scale planting and picking cotton has high economic efficiency < /strong > < /p >

< p > in order to achieve cotton planting in arid areas, pgenic cotton was successfully developed after China Cotton Breeding domestic pgenic insect resistant cotton.

Yu Shuxun said that in the 30 to 50 cm soil layer water content is only 5% - 8%, drought resistant cotton can still grow normally, creating conditions for planting cotton in dry land in Mengxi county.

< /p >

< p > Yu Shuxun also gave an economic account to reporters, using the mechanized cultivation and harvesting technology developed by China Cotton Research Institute to save water, save fertilizer, save labour and increase production.

That is to say, the traditional field irrigation has 500 cubic meters of water per mu, and the drip irrigation technology under the cotton demonstration field is only more than 200 cubic meters per mu. The fertilizer is drip irrigation with water, saving 150 yuan per mu of fertilizer input, and eliminating the main labor sectors such as artificial watering, fertilization and cotton picking. Only one mechanized harvesting is saved, and the seed cotton is saved by 1.6 yuan per kilogram. In order to facilitate large area mechanization operation, the actual land saving is 13%.

< /p >

< p > Li Xin said that his cotton field yields 400 to 500 kilograms of seed cotton. According to the purchase price of 1 kilograms of 8 yuan, the output value of cotton per mu is about 3200 to 4000 yuan, and all kinds of investments are plough off, and net income exceeds 1000 yuan, much higher than the income of local corn planting.

< p > < strong > alleviating the contradiction between cotton and grain and improving Inner Mongolia's ecological environment < /strong > /p >

< p > according to statistics, China's cotton demand exceeds 10 million tons a year, and its self-sufficiency rate is about 70%.

As China's "a target=" _blank "href=" http://www.91se91.com/ "> textile" /a "exports increased rapidly, cotton production demand gap gradually expanded.

On the other hand, the arable land is decreasing year by year, and the contradiction between cotton and grain is serious.

< /p >

< p > Yu Shuxun said that the Alxa League was able to grow corn. The whole growth period needed 600 to 800 square acres per mu of water, and only 250 to 400 square acres of water could be used for planting cotton. It could save water from 30% to 60%.

< /p >

< p > "in the next 5 to 10 years, the development of 5 million mu of cotton in the western region at the core of Alxa League means that the mainland can reduce about 10 million mu of cotton fields for grain production. According to the calculation of corn yield of 1500 kg / mu in the mainland, the annual grain yield can be increased by 700 to 8 million tons, which is conducive to solving the contradiction between grain and cotton and promoting national food security."

Yu Shuxun said.

< /p >

< p > > a href= "http://www.91se91.com/news/index_p.asp" > Alxa League < /a >. The dry land is short of water and soil, salinization is heavy, vegetation is few, long term nudity, wind erosion and desertification become more and more serious.

Zhang Jianzhong said that planting cotton in such areas not only can fully develop saline alkali dry land and limited water resources, but also increase vegetation coverage and reduce evaporation and dust suppression. During the growth of cotton, it also absorbs saline alkali components in the soil and protects and improves the local soil and ecological environment.
