BEIJING, Oct. 27 (Xinhua) -- The following is a summary of published science and technology news of China.
CHINA'S NEW REMOTE-SENSING SATELLITES
China successfully sent a group of new remote-sensing satellites into orbit from the Xichang Satellite Launch Center in southwest China's Sichuan Province on Monday.
Belonging to the Yaogan-30 family, the satellites were launched by a Long March-2C carrier rocket at 11:19 p.m. (Beijing Time).
The satellites have entered the planned orbits and will be used for electromagnetic environment detection and related technological tests.
NEW SINGLE-DOSE FERTILIZATION METHOD
Chinese researchers have successfully applied single-dose fertilization in mechanized rice planting to reduce nitrogen cost.
Researchers from the Nanjing Agricultural University adjusted the ratio of slow-release fertilizer and controlled-release fertilizer. Instead of fertilizing the traditional four to five times, now they only need to fertilize once.
A joint study conducted by Chinese and Spanish researchers has found that soil microbes are closely related to crop yield, and the protection of certain microbes may help reduce the need for fertilizers and increase crop production.
Researchers conducted a statistical analysis of bacteria, fungi, nematodes and other microbes in soil samples. The results showed that some soil microbes, such as nitrogen-fixing bacteria and photosynthetic bacteria, are closely related to the growth of crops.
