Background technology
Oryza sativa L. is one of world's staple food crop, in the world nearly half population, with rice as food, is produced throughout removing
Each continent beyond south, the arctic；20 end of the centurys, 400,000,000,000 kilograms or so of View of World Rice annual production average out to, cultivated area is about
1.45 hundred million hectares.It is one of important cereal crops in rice in China, rice in China sown area accounts for national cereal crops
1/4, about 35,000,000 hectares every year, and yield accounts for the 50% of total grain output.No matter cultivated area or yield, in Grain in China
Rank first in crop.
The rice field of all rice workspaces of China, particularly Zhejiang, Jiangxi, Jiangsu, Anhui etc. are saved with water direct seeding or direct-sowing dry
Rice terrace, has a large amount of weeds；Oryza sativa L. has plantation all over China, and weeds in paddy field species is various, various places rice region weeds
Species is different.According to statistics, national rice field constitutes the weeds of harm more than 200 kinds, wherein it is most common, endanger and heavier have
More than 40 plant.It is documented that, national rice field crop smothering more than medium (2～5 grades) crop smothering area up to 1546.7 ten thousand hm2, account for
The 46% of total cultivated area, wherein seriously causing harm (4～5 grades) area for 3,800,000 hm2, account for the 11.5% of Monitoring of Paddy Rice Plant Area.
