States are in close concern China of food production trends. but currently in China of agricultural Foundation still is weak, effect in China food needs and production of many adverse factors will long-term exists (population: 2030 in China population up 1.65 billion, food gap 140 million tons; farmland: town of, and road construction, Salvatore Ferragamo Handbags threat occupied farmland; pollution: annual only heavy metal pollution and production food up 10 million tons; disaster: 2010 disaster loss food 16.8 billion kg, directly loss 150.9 billion yuan). so, For a country with 1.3 billion people, only based on self-sufficiency, food supply and demand balance and to ensure long-term peace and stability of the country and society. grain output factors leading to changing according to 1952-2008 56 years of the sown area of grain, grain yield and grain output in China analysis found that more than 50 years to determine dominant factors of grain output in China is changing. century on 5
0 era, in China food yield is low, per acre in 100 kg around, total with sown area of increase or decrease and fluctuations; Shang century 60 to 90 mid, in China food yield continuous Salvatore Ferragamo Handbags 34 years keep growth, from per acre 100 kg growth to 300 kg, during grain broadcast area although has reduced, but total rendering fast growth situation; recently 10 years, food yield wandering in 300 kg around, and appears has like Shang century 50 generation as of scene, is food sown area into has decided food total of led factors, Total sown area increase or decrease volatility. China's grain output since 1998 after it reaches the highest value 512.3 million tons, followed by 5 years of continuous decline, by 2003 lows, fell to 430.7 million tonnes. Since then, the Government has taken a number of supporting measures, total grain output to begin the recovery of growth. by 2008, total grain output to your 528.5 million tons, only for the 1998 water
Flat. recently 10 years of situation although and Versace Handbags Shang century 50 generation similar, but nature is has is large of different, is in China food production appears has a new of turn: from fast growth into slow growth of new stage. main challenge still to conquered farmland reduced and population increased. as February 2011, national farmland total area only left 1.826 billion acres, than 1997 of 1.949 billion acres reduced 123 million acres, China per capita cultivated area by more than 10 years Qian of 1.58 acres reduced to 1.38 acres, Only 40% per cent of the world's average, bottom line was approaching 1.8 billion acres of food safety requirements. 2030, China's population is expected to reach 1.45 billion, major grain crop yields need to continuously improve. shortages. China's per capita water resources only 2,220 cubic meters, about the world's average of one-fourth, Versace Handbags agricultural water consumption accounted for 65% of water resources consumption in 2020, agricultural water gap is estimated to reach 100
0 cubic; national average annual drought area up 21.8 million hectares, serious disaster 8.39 million hectares, food production 10 billion kg above. annual due to deficiency water caused national economy loss up more than 200 billion yuan. also, nitrogen, and phosphorus fertilizer dosage accounted for world dosage of 30%, and in China phosphorus mine resources only 2.7 billion tons reserves, only enough using about 70 years. natural disasters and international competition. 1998-2004 years, in China due to natural disasters annual food loss up 50 billion kg, Shang century 90 generation pest of outbreak area over 25.4 million hectares, than 80 generation increased has 41%.2010 years, in China imports corn 1.57 million tons, for last year of 19 times times; imports wheat 1.2 million tons, also than Shang a years, increases for 36%; rice imports volume also increased to 366,171 tons, more Qian a years incremental near 29,000 tons, this a data does not including through southern border of rice smuggling of

, These measures will in short time within play major role, however from long-term angle see, they play role of ability will will increasingly small. solution food problem of fundamental way also is to relies on technology of continued progress, technology innovation will for improve food yield and quality brings unlimited broad of development space. are because so, implementation food high yield engineering a by policy, II by input, three by technology. future food total of growth main by yield of improve, Yield of improve to by integrated agricultural technology. China Academy of research results indicates that, fine varieties and advanced of cultivation technology on food yield of contribution rate respectively accounted for 33.8% and 34.1%. seed in in China agricultural cost constitute in the accounted for than about for 12%, slightly is greater than pesticide of 7%, and far below fertilizer of 44%. pesticide and fertilizer over 50% of high input, not only is in China agricultural production faced of grim of industry crisis, also reflect has in China related technology development of absence, worth agricultural
