Cotton Production Rate Increased Substantially To Solve The Quality Dilemma

In the final analysis, the quality is not the same. Some people say that it is a cotton seed problem. Some people say that it is a post processing technology problem. This is an old topic. How many people have written this book is a new topic. After all, China's machine picked cotton is at its infancy. With people's in-depth understanding, the curtain gauze covering the machine picked cotton has been gradually opened, and it has gradually revealed the truth.

Recently, an industry official declared, "domestic machine picked cotton should be called cotton picked by machine", which sounds a bit awkward, but it points to the key. At present, cotton picking cotton is almost entirely used for picking cotton in China. Sowing seeds are required 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 the harvested cotton is still quite different from that of the cotton pickers. This is not the cause of machine equipment but the problem of cotton seeds. Up to now, no cotton variety suitable for mechanized harvesting has been approved by the state.

An expert from the Cotton Research Institute of Chinese Academy of Agricultural Sciences said to China cotton net reporter that the direction of research and development of machine picked cotton and hand picked cotton varieties is quite different. First, the machine picked cotton seeds require cotton boll and boll opening to maintain a high degree of consistency. Hand picking cotton seeds are the best way to prolong boll opening and bolting time; the two is cotton picking. Machine picked cotton seeds Cotton boll and boll opening should be concentrated in the middle part of the cotton plant, not too much on the lower part, otherwise the machine will be interfered by plastic film when picking. When picking cotton seeds, the cotton bolls will be bolled and the output will be increased. Three, cotton picking and bolting are required to concentrate and facilitate harvesting. Four, in order to deal with the later multi-channel cleaning process, the cotton seed length and strength of cotton seeds were higher than that of hand picked cotton seeds.

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, what is the difference between hiding the ears and stealing the bell?

One side is the development of China's relatively backward cotton harvester, but the other is the rapid development of machine picked cotton. A cotton professional has conducted research on the northern Xinjiang masters two years ago. At that time, the percentage of machine picked cotton was 90%, six Division 50%, seven division 50%, eight division 89%, while the proportion in 2014 increased to five 90%, six Division six, division division, and more than five divisions. Basically, in addition to the corners and corners, all Corps in North Xinjiang had achieved full machine operation. It is worth noting that the promotion and popularization of local mining in the northern Xinjiang are also accelerating. From two years ago, the plant spacing and row spacing sampling survey showed that the rate of mechanical recovery would not exceed 30%, and by 2014, the ratio of local mining production in Northern Xinjiang had exceeded 60%. Although the rate of machine production in southern Xinjiang is still only half of that in Northern Xinjiang, considering the huge difference in planting costs, the trend of machine production is overwhelming.

How can we solve this problem? China's famous cotton genetics and breeding family tree Xun said, now the mainland. Cotton spinning enterprise It is normal to think about the quality of machine picked cotton in Xinjiang. It is normal that impurities and quality decrease. It is normal for Xinjiang to develop machine picked cotton, which is the last 5 years, and the United States and Australia have been developing machine picked cotton for more than 100 years. At present, it is imminent to establish a new technology system for machine picked cotton suitable for high production in Xinjiang. Researchers should focus on tackling two aspects: first, efforts should be made in the selection of new varieties, and high yield, high quality and new varieties should be selected to reduce the loss of machine production; two, efforts should be made to clean the flowers and equipment and technology, so as to reduce the damage of impurities to cotton quality.

Visible machine cotton quality control is a set of process system, primary and secondary contradictions must be resolved. First, absorb and import advanced technology from abroad to produce cotton pickers which are really suitable for domestic cotton harvesting. Secondly, we should not only improve the process of cotton ginning, make it more suitable for cotton picking, but also reduce the skin cleaning process appropriately for textile enterprises. Cotton fiber The importance of index such as length and intensity is much higher than that of lint index. Once again, we should increase the technological improvement and experience accumulation of textile enterprises, purchase relevant equipment for processing cotton pickup, and finally, improve the cotton target price subsidy system, further play the role of the market, promote the formation of competition and the Bureau of quality and price.

From the point of view of experimental research, demonstration, technology maturity, large area application and the general rule of 10 years, China's machine picked cotton seeds still have a long way to go. As a key factor, cotton seed problem is not a problem that can be solved overnight. How to concentrate the advantage of scientific research technology to overcome difficulties, not only develop high-quality cotton picking seeds, but also improve the various processes and technologies in the latter stage, which really test the wisdom of all relevant research institutes, and also a necessary way to rapidly upgrade the quality of machine picked cotton in China.
