BEIJING, Aug. 1 (Xinhua) — The following is a summary of published science and technology news of China.
LUNAR SAMPLE
After studying a lunar sample brought back by the Chang’e-5 mission, a group of Chinese scientists proposed a continuous early crust development process on the moon, as opposed to the classical two-stage moon crust development model.
The study, which was recently published in the journal Communications Earth & Environment, provides direct evidence that lunar anorthosite and the parent magma of the magnesian-suite rocks formed simultaneously.
PHOSPHORUS FERTILIZERS
Among tens of millions tonnes of inorganic phosphorus fertilizers used every year in the world, only 12.6 percent is absorbed by plants, with the majority stored in soils, according to a recent study by botanists from the Chinese Academy of Sciences (CAS).
A research team from the South China Botanical Garden under the CAS has established a global database, which includes 987 sets of observation data from 274 papers published between 1972 and 2021.
According to the study published in the journal One Earth, these findings deepen the understanding of the phosphorus cycle in terrestrial ecosystems and offer valuable guidance for the management of phosphorus fertilizer in agricultural practices.
SCI-TEC, ADVANCED-MANUFACTURING HUB
Shenzhen, a vibrant sci-tech and advanced-manufacturing hub in south China’s Guangdong Province, has seen trade volume reaching 2.2 trillion yuan (about 308 billion U.S. dollars) in the first half of this year, marking a year-on-year increase of 31.7 percent and accounting for 10.4 percent of China’s total, according to Shenzhen Customs.
Shenzhen’s robust manufacturing sector is the backbone of its trade advantage. In the first six months of this year, Shenzhen’s export volume of electrical and mechanical products reached 948.9 billion yuan, up 21.4 percent year on year.
