The yield exceeded 6.9 tons per hectare for the first time, and the total output has exceeded 200 million tons for seven years; the rice market remain weak but slightly stronger than 2016; both the imports and exports of rice increased, with a historical high import volume by 4 million tons and a unparalleled year-on-year growth of export volume by 210%; the number of rice varieties approved by the state increased substantially, and technology for green farming developed rapidly. The rice area is projected to decrease in 2018. It is predicted that there is going to be increased volatility for rice price and continuous increase in both imports and exports of rice. The supply-side reform in rice industry will continuously develop by wider applications of technologies for green farming.

Analysis on International Competitiveness of Japonica Rice in Northeast China—Based on the Comparative Data of Japan and Korea 2018, 24(2): 47-51.  DOI: 10.3969/j.issn.1006-8082.2018.02.012 Abstract ( )   PDF (627KB) ( )   After joining the World Trade Organization （WTO）, China's grain import and export trade was much negatively affected. Compared with the trade of corn, soybeans, wheat and other crops, the trade of rice gets the minimum impact, and the competitiveness of japonica rice even gets enhanced. With the improvement of living standards, people's demand for high-quality japonica rice is increasing, as well as the rice trade is also increasing in the international market, and Japan and South Korea are major importers of japonica rice. Northeast China is one of the Chinese major japonica rice producing bases, whose area is nearly 2.67 million hectares, accounting for nearly half of the national japonica rice. It’s well known that Northeast China, Japan and Korea are main consumer markets as well as the major producers of japonica rice. The production and consumption of japonica rice are always undergoing direct intervene and key control from their government. This paper quantitatively analyzed the international competitiveness of japonica rice over Northeast China, Japan and Korea, which is based on the contrast of current situation in above regions by using the index of trade competitiveness. Finally, according to the main factors affecting the international competitiveness of japonica rice, some suggestions are put forward to enhance the international competitiveness of japonica rice in Northeast China.

Compared with the control, the yields of the 4 pesticides treatments were increased by 4.38%~7.89% respectively. The control effect of application pesticide 1 time each at 10 days before rupturing, 3 days before rupturing and after heading was significantly better than that of 1 time each before rupturing and after heading, and once after heading. There was significant difference in yield among the 3 treatments. The control effect of application pesticide 1 time each before rupturing and after heading was similar to application pesticide once after heading, but the difference of yield was not significant.
