Examine the major crops of wheat, corn and soybean for acreage, yield per unit area and planting area in China, such as the production of the field and study the costs and profitability of these crops. Also it examined the per capita consumption of staple foods and urban and proportion, the area cultivated with arable land utilization, and Chinese imports into these three crops of the rural population in China. Examine the wheat, corn and soybean crop varieties development agencies, and can cultivated varieties, such as bar who investigated comprehensively, and forecast the impact will have on our country. As a result, wheat and corn are already achiving food self-sufficiency but in recent years the trend of increasing import of these crops in China. And soybean is circumstances that are purchased for one-third of world production. Therefore, the possibility of these crops to be introduced in Korea is determined to be a little. Recent changes to two from one family, one child at a national policy of China, and increases the population, would be increased consumption of food. Therefore, if not a few have an impact on world grain prices, it is expected to be the indirect effects on supply and demand of these three crops far our country.

This study was conducted on to investigate the present status and prospect of vegetable production in three northeastern provinces(Hilongian,Jilin and Lianoning) of China. According to agricultural statistics of China,Total vegetable cultivated acreage of three northeastern provinces appears to about 4.5%(953.7 thousands hectare) and total vegetable production appears to 6.5%(4951.7 thousands metric tons) of China,Total vegetable cultivated acreage of China increased suddenly between 16% to 40% during 15years from 2000 to 2014,But on the other hand, three northeastern provinces decreased about 10~15% every years during its times,also the only, In case of Lianoning province,vegetable cultivated acreage and production increased every years. The chief vegetable producing places are the Chaoyang and Shenyang in Liaoning,Changchun and Songyuan in Jilin, Harbin and Mudanjiang in Heilongian province.Also,the chief vegetable producing places of protected culvation are Changchun, Songyuan and Siping in Jilin province,At the this places are producing about 65% of total three northeastern provinces production in 2014. The northeastern region of China, especially, Heilongjian province is the main producing region of grain(wheat,maize,soybean and so on),Laioning and Jilin provinces are the main producing region of outdoor vegetable crops culture and protected vegetable culture. In future,It is necessary to carefully consider its impact on the domestic vegetable industry for increasing the importing of condiment vegetable from China owing to FTA between Korea and China.

Approximate situation of potato industry was investigated for three northeastern provinces(Heilongjian, Jilin and Liaoning) in China. Chinese agricultural statistics for potato crops include potato and sweet potato. The acreage and production for only potato appears to cover approximately 60%. According to agricultural statistics of Jilin province, the acreage for only potato is estimated to be 91%(67,000ha) of total potato crops acreage of 74,000ha. In the ratio of only potato acreage compared to total potato one, Heilongjian province is the highest and the lowest result was observed in Liaoning province. The acreage, production and yield of potato have consistent increased since 1990 in China. The acreage of potato increased from 2,829 thousands hectare in 1990 to 5,647 thousands hectare in 2014. Yield per hectare increase from 2,264kg in 1990 to 3,405kg in 2014. In conclusion, total potato production increased rapidly from 6,404 thousands metric tons to 19,227 thousands metric tons. Potato crops acreage and production of three northeastern provinces were 3.7% (328 thousands hectare) and 6.5%(2,171 tons) of acreage and production of China respectively. This result was higher than overall average of China, that is 3.3% for Heilongjian, 1.7% for Jilin and 1.5% for Liaoning. The main cities for production of potato crops in northeastern provinces of China is Qiqihar for Heilongjian, Changchun for Jilin and Tieling for Liaoning.
