Rice and corn grain filling will be affected, southwestern China to see low temperatures and scant sunshine over the next ten days
Since late July, most of southwestern China has had many rainy days, with sunshine hours in Yunnan and Guizhou 30% to 80% below the same period in normal years; temperatures have been low, with Yunnan's average temperature at 21.1°C, the lowest since 1990. Single-season rice in southwestern China is at the critical stage of heading and flowering and grain filling, while summer corn is at the tasseling to grain-filling stage. Low temperatures, rain and scant sunshine will inhibit or delay rice flowering, causing poor pollination of rice ears and an increased rate of empty grains; at the same time, low temperatures and scant sunshine will also affect the grain-filling rate of rice and corn, leading to a decline in grain weight.
