Smog casts shadow over crop growth, SCMP says

Worsening smog on the mainland is blocking natural light and could spell disaster for agriculture, the South China Morning Post reported Wednesday, citing scientists. He Dongxian, from China Agricultural University’s College of Water Resources and Civil Engineering, said chilli and tomato seeds, which normally take about 20 days to grow into seedlings under artificial light in a laboratory, took more than two months to sprout in a test at a greenhouse farm in Beijing’s Changping district. Membranes and pollutants sticking to the greenhouse’s surface halved the amount of light reaching the plants, the report quoted He as saying.
