1 The world's first liquid-phase breeding chip for sea cucumber was successfully developed
The accuracy of traditional breeding is low
At present, traditional breeding techniques such as cross breeding and selective breeding still dominate the variety breeding of sea cucumber. Traditional breeding techniques mainly rely on phenotypes for seed selection, and large sea cucumbers are usually selected to be kept as seeds for breeding. In fact, the size of sea cucumber is not only determined by genes, but also influenced by environmental conditions and bait. If the seed ginseng grows big, its baby will not necessarily grow big, while genome-wide selection breeding will help sea cucumber achieve "prenatal and postnatal care".
breeding chip realizes "prenatal and postnatal care"
24K liquid-phase breeding chip is developed on the basis of genome resequencing and whole genome analysis of Stichopus japonicus. Farmers only need to take a few wart feet from the sea cucumber to be selected. Through gene analysis of breeding chip, professionals will provide farmers with the best seed selection and breeding scheme, that is, how to pair the seeds and ginseng, so that the offspring will grow faster, have high nutrient content, or be more resistant to high temperature and disease, while maintaining the genetic diversity of the whole population. R&D personnel said that the follow-up chip technology will be further upgraded to continuously improve the detection accuracy and further reduce the cost.
2 China's soybean and oilseed production capacity improvement project started well
This year, the central government subsidized 15 yuan per mu to develop the rice and winter rape rotation mode in winter fallow fields. In northeast China, farmers are guided to grow more soybeans by carrying out grain-soybean rotation. Heilongjiang will co-ordinate 1 billion yuan of agriculture-related funds this year to support the expansion of soybeans by more than 1 million mu. In addition, this year, the state promoted soybean and corn strip compound planting in the northwest, Huang Huai Hai, Southwest China and the Yangtze River basin, carried out soybean planting demonstration in saline-alkali land, and strived to expand the soybean planting area nationwide to more than 14 million mu.
3 "group-type" assistance work for educational talents is carried out
It is reported that the two departments have selected 247 outstanding backbones with good political quality, young age and rich teaching experience from eight eastern provinces to serve as principals in key rural revitalization counties in western countries. At the same time, the eastern and western provinces * * * are equipped with middle-level cadres and first-line excellent teachers to provide comprehensive assistance to the school and promote the overall improvement of local education quality.
In 24, the "Silver Age Plan" will recruit 5, lecturers for compulsory education.
The implementation scope of this year's "Silver Age Plan" is based on counties, mainly poverty-stricken areas, underdeveloped ethnic counties, revolutionary old counties, border counties, etc., focusing on deep poverty-stricken areas such as national rural revitalization counties and the original "three districts and three States", and the aided schools are mainly inclined. The retired teachers who apply for the "Silver Age Program" are mainly principals, teaching researchers, special-grade teachers and backbone teachers. The personnel relations and the retirement benefits enjoyed by lecturers during their service remain unchanged.
5 Baoshan, Shanghai: The "points system" helps to build a civilized rural style
Covers rural life
The "Baoshan Governance" points system used by Tangwan Village sets up four major items, including villagers' deliberation and civilized new style, covering all aspects of rural life. Villagers can get points by signing promises or declaring honors, and of course they may be deducted for violations.
so, what can the villagers do with the points? In the "point supermarket" opened in the village, villagers exchange points for basic daily necessities. In addition, the village has also set up a ranking list of points. Through the ranking list, residents who are enthusiastic about public welfare and civilized and environmentally friendly on weekdays are known by more villagers, with good behavior, high points and more exchanges. "Those who have virtue have gains" make the leading demonstration role better played.
offline promotion promotes participation
At the beginning of its implementation, Tangwan Village adopted the "Bao Shanzhi" integral system operated on a smart machine. However, in practice, it is found that some villagers' enthusiasm has been dispelled by unskilled operation. To this end, Tangwan Village changed to a paper point card, so that villagers can experience the benefits of exchanging points for gifts first, and at the same time publicize and promote the specific operation methods of the point system. After the experience, the villagers' interest in the points system was greatly enhanced.
With the implementation of the points system, village affairs and villagers' interests are organically combined, which not only saves management costs, but also improves governance efficiency. Up to now, the integral management system of Tangwan Village has covered more than 9% of the households in the village, and more and more villagers have taken the initiative to participate in various activities organized by the village, consciously abiding by village rules and regulations, and improving the level of rural civilization.

6 "Enterprise+Cooperative" breaks through the "last mile" of farmland water conservancy project
Before introducing social capital and market players
, the medium-sized irrigation area of Hate Tiger Dam has no supporting facilities such as branch canals, and the cost of pumping water by the surrounding people is too high, resulting in more than 3.5 million cubic meters of water in the reservoir every year. In 214, through strict investment procedures, the luliang county Municipal Government and Gansu Dayu Water Saving Group signed an agreement, and enterprises and cooperatives invested in the establishment of Luliang Dayu Water Saving Agricultural Technology Co., Ltd. at a ratio of 7︰3, which became the main body of farmland water conservancy investment, construction and management.
after the pilot project, the company built two new pumping stations, laid 243 kilometers of trunk and branch pipelines and 1111 kilometers of field pipe network, and supported 548 sets of automatic water control systems and field metering facilities, with an area of 1,8 mu of efficient and water-saving micro-irrigation.
farmers spend a little money to enjoy welfare
while local farmers can enjoy welfare beyond the reduction of water cost. Because the water supply is guaranteed, the land in the village can grow crops for two or three seasons, and the income is two or three times that of the past; Because of the convenient use of water, the multiple cropping index of the land has been improved, the villagers have grown more crops, and the problems of pests and diseases caused by a single crop have become less. In addition, the improvement of irrigation conditions has made the land here a "fragrant cake". In the past, it was difficult to rent out all the land, but now the rent per mu exceeds 2 yuan, which is more than 1 yuan higher than the surrounding area.
From rebuilding light management to management and protection in place
At the same time, the local government has formulated the Measures for Management and Protection of Field Projects, clarifying the responsibilities of enterprises, governments and the masses to ensure that field projects can be managed well and benefit in the long run. In order to make the company cooperate effectively with farmers, villagers voluntarily set up water professional cooperatives to participate in the management and operation of water conservancy projects. The masses are both water users and "project investors". Giving full play to the spirit of ownership and participating in project management and protection is conducive to long-term management and protection and good use of water conservancy facilities. In this mode, the utilization coefficient of irrigation water is increased to above .85, which solves the problem of "one year construction, two years use, three years failure, occupied and unattended" of water conservancy projects.
In 27, the scientific research team of the Chinese University of Science and Technology found that the scientific mechanism of "sound can relieve pain"
It was 5 decibels higher than the ambient sound, and the effect was obvious
During the experiment, the researchers played three different types of sounds to mice with inflamed claws, namely soothing music, incongruous notes and white noise. The results showed that the three kinds of sounds could effectively relieve the pain of mice when played at low intensity, but had no obvious analgesic effect when played at high intensity. The researchers also placed the mice in environments with different intensities of background sound, and found that the sound about 5 decibels higher than the ambient noise can effectively relieve the pain of the mice.
It opens up a new direction for analgesic research
The auditory cortex is the highest brain center for sound processing, and it will analyze the sounds carefully. Using the virus as a neural tracer, the researchers tracked the auditory cortex output of mice all over the brain, and found that a large number of auditory cortex neurons projected to the somatosensory thalamus, and found that low-intensity sound could inhibit this projection. In addition, the researchers said that this is true in mice, but the mechanism of human brain is much more complicated, and the relief effect of sound on human pain deserves further in-depth study.
The doctor warned that 8 "cooling artifact" should be used with caution!
liquefied petroleum gas and alcohol are flammable substances
The main components of cooling spray are liquefied petroleum gas and alcohol. The reason why the temperature can be quickly cooled is that the physical characteristics of these two components are volatile and absorb heat are utilized. However, both liquefied petroleum gas and alcohol are flammable and explosive, and once they are not handled properly, dangerous events are prone to occur. Not long ago, Mr. Yin, a citizen of Changsha, lit a cigarette after using a cooling spray in the car, which led to an open flame in the car and burns on his face and arms. Fortunately, after timely treatment by doctors, his condition was controlled stably.
In addition, long-term exposure to butane, propane and other components in liquefied petroleum gas can easily lead to poisoning, and if the butane component is large, it may also lead to frostbite.
Wash with cold water immediately in case of accident
Sunscreen spray, air freshener, hair gel, etc. are all compressed canned products, which are prone to explosion when heated; Antiperspirant dew, perfume, toilet water and toner all contain a certain amount of ethanol (alcohol), and you should also avoid contact with open flames when using them. The doctor reminded you not to panic in case of an accident. You should immediately leave the fire source and wash the burned area with cold water or tap water for 2-3 minutes. You must never forcibly tear off the clothes on the burned area to avoid secondary injury. After cooling the wound, you should go to a regular hospital in time, don't listen to the remedies, and minimize the adverse consequences.
