Development Of Machine Picked Cotton Should Be Based On Quality Assurance.

In the cotton sales this year, Xinjiang picked cotton more expensive than machine picked cotton, but it was sold out by enterprises. Why? In the final analysis, it is quality. Cotton quality is an old topic, but it is the most concerned topic of cotton textile enterprises.

Cotton harvester is welcomed by cotton harvester, but textile enterprises are afraid of it.

Zhang Hongxia, chairman of Shandong Wei Qiao textile limited liability company, said that the quality of cotton in Xinjiang is better this year, but

The problem is very serious, especially the machine picked cotton, high impurity content, plastic film used in the process of planting, is sucked into cotton by cotton picker, which brings great trouble to the production of textile enterprises.

In this regard, an industry insider said: "domestic machine picked cotton should be called machine picked cotton".

It sounds a bit awkward, but it points to the point.

At present, our country

Almost all cotton seeds with hand picked cotton are planted according to the specific spacing and spacing of machine tools. During the growth period, cotton picking is also a management mode, and only mechanical operations are used at the last harvest.

And overseas from professional breeding, field production management until the last harvest operation, there is a set of specifications for tailored cotton.

China has imported advanced cotton pickers from abroad, but the quality of harvested cotton is still quite different from that of foreign machine harvested cotton. This is not the reason for machine equipment, but the problem of cotton seeds.

At present, a cotton variety suitable for mechanized harvesting has not been approved yet.

Experts from the Cotton Research Institute of Chinese Academy of Agricultural Sciences said

There is a big difference between the research and development direction of hand picking cotton seeds.

Species require cotton bolls and bolls to be highly consistent. Cotton picking is the best way to prolong boll setting and bolting time. Two, cotton picking and bolting are concentrated in the middle part of cotton plants, and not too much on the bottom. Otherwise, the cotton picking will require cotton boll to increase the output. The three is that the cotton picking and bolting parts are centralized and easy to machine, and the cotton picking plants require more cotton plants to ring for 4 weeks. Four, in order to deal with the later multi-channel cleaning process, the length and strength of cotton seeds are higher than that of hand picked cotton seeds. First, machine picked cotton.

It can be seen that it is easy to sow cotton seeds in accordance with the mode of machine harvesting, which will affect the quality of cotton.

Even if the later processing equipment and technology are advanced, the production demand of high-end products of textile enterprises can not be achieved.

Cotton genetics and breeding Jiayu Xun said that now the cotton textile enterprises in mainland China have a view on the quality of Xinjiang's machine picked cotton, and think that more impurities and lower quality are normal, because Xinjiang's development of machine picked cotton is the last 5 years, while the United States and Australia have been developing machine picked cotton for more than 100 years.

At present, it is imminent to establish a high-yield and new cotton picking technology system suitable for the national conditions in Xinjiang.

Researchers should work hard in breeding new varieties, and select high yield, high quality and new varieties, so as to reduce the loss of machine production and reduce the damage of impurities to cotton quality.
