The Disaster Impact of Wheat Drought Disaster

Wheat drought disaster is the main agrometeorological disaster in China's wheat area, especially in the northern winter wheat area (north of Qinling-Huaihe line), which has the greatest impact in three periods: sowing date, jointing-heading date and filling-maturity date.

The affected area of wheat in the northern region is more than 65.438+0.4 billion mu, and 43% of the wheat fields suffer from drought. The affected areas include Shandong, Shanxi, Henan, Hebei, Gansu, Beijing, Shaanxi and other places, causing direct economic losses of at least $234 million.

70% of wheat in Anhui province was affected, 60% of wheat fields in Henan province were affected, and nearly half of other provinces were affected. The reason for the drought is that the precipitation in the northern region has been greatly reduced since June 5438+065438+ 10, 2005. The drought degree in some areas occurs once every 50 years, and the rainfall is 90% less than that in normal years.

The output of wheat producing areas will be reduced by 20%. If the spring drought continues, the situation will be much more serious. The Ministry of Agriculture has launched a first-level drought-resistant plan to substantially increase the minimum purchase price of wheat.
