To grow rice in space! Quest Tiangong two will carry those space experimental space laboratory module source: Xinhua viewpoint WeChat public, China’s first true sense of the number two will be held in September 15th this year to 20, choose the launch. The task will be carried out more than ten Chinese scientists in the sophisticated, manned space mission is the previous application project is one of the largest. Some of these experiments are to explore the deepest mysteries of the universe, some to help people better understand the ocean and the atmosphere, and some even want to solve the future star trek food problems…… You may recall that the movie "Mars rescue", the protagonist alone to overcome the difficulties, through the cultivation of potatoes on Mars base to survive, and finally return to earth. At present, the territory continues to expand human space exploration, from earth orbit to deep space exploration, from the establishment of a base on the moon to Mars to survive. The so-called "An army marches on its stomach". The first task is to solve the problem of food self-sufficiency, oxygen and circulating water. Is it possible for the green plants on earth to grow normally in space so as to provide food and oxygen for humans? Although in space has conducted a number of plant growth test, but to successfully achieve food and vegetable production in the space conditions, but also need to solve many problems of extreme environmental factors including microgravity, the effects on plant growth. Higher plants the Tiangong two space lab to conduct the training experiment is to study the problem. "Plant astronauts" — rice and Arabidopsis Chinese used to eat rice, so we are familiar with rice and a different growth characteristics of higher plant Arabidopsis thaliana was elected as "lucky plants, the astronauts will be equipped with Tiangong two, an extraordinary journey into space. The incubator for Arabidopsis, the rice Tiangong two equipped with higher plants, is a miniature version of the space greenhouse, it has an important job, will be carried out for the first time in China for a period of 6 months of plant "from seed to seed" the whole life cycle of culture. Scientists will be able to directly observe the seeds of different plants in space, germination, growth, flowering and seed setting, so as to better understand and master the future space of agricultural development. Higher plants incubator (left), divided into orbit and return unit unit in orbit unit can provide two Arabidopsis cultured cells and two rice cultivation unit, respectively for a long day and a short day conditions (such as plant culture right diagram), return unit for the cultivation of Arabidopsis thaliana. How did the experiment proceed? Botanists in the ground carefully selected rice and Arabidopsis seeds in a dormant state to ride in the warm warm box "with the Tiangong two into orbit. Scientists will be on the ground remote command, start the experimental process, the seeds began to germinate. After a period of time, incubator through the temperature, humidity, light, nutrient supply and other functions for the growth and development of the seed to provide environmental protection. Expected 1 – 2 months later, if the growth is smooth, the plant can enter the bud (spike) flowering stage. Long

Chinese Import & export and foreign exchange surplus differences explain why – official news agency of the new network in September 22 Beijing Xinhua (reporter Zhao Jianhua) China State Administration of foreign exchange (hereinafter referred to as foreign exchange bureaus) often project management Secretary Du Peng 22, said in Beijing, the customs import and export goods trade surplus and foreign exchange surplus, on the surface there is a certain correlation. But there is a big difference between the two statistics, if direct comparison, may produce a misreading of the judgments of international balance of payments situation. The same day, foreign exchange management policies on the foreign exchange bureau held a news conference, a reporter asked, the first 8 months of this year, far greater than the foreign exchange bureau Chinese customs import and export surplus foreign exchange surplus of trade in goods, which are factors of false trade. In this regard, Du Peng said that the two statistics point, different projects have different enterprises of foreign exchange and other behaviors also affect the statistical data. These factors have resulted in the customs import and export data and trade in goods does not match the data exchange between nodes. It is unscientific to judge the existence of false trade only by the difference of two data, and the two data are not comparable. Du Peng stressed that the current project management has been achieved electronically. From the current monitoring situation, did not find a large amount of funds through cross-border trade and cross-border arbitrage of false trade situation. Du Peng said that this year, the foreign exchange bureau to carry out special inspections for the import and export trade in goods, trade, payment of a large volume of business and the rapid growth of the region, a comprehensive verification analysis of cross-border capital flow anomalies including false trade, but also to strengthen the close cooperation with the customs, taxation and other relevant departments, to achieve data sharing and information sharing, mutual recognition and enforcement of law enforcement. Judging from the situation, there is no abnormal outflow of funds found in the case of large-scale outflow. (end)
