It is predicted that in 2003, the summer grain will decrease, the summer oil will increase, and the dominant varieties will increase

Introduction: new page 1 according to the comprehensive statistics and analysis of the agricultural situation of the Ministry of agriculture on May 10, this summer's grain and oil production is basically stable, showing the trend of summer grain reduction and summer oil increase, and the development pace of variety structure optimization, regional layout adjustment and order agriculture is further accelerated According to the summary and analysis of the data reported by 26 provinces (districts and cities) of summer grain production, it is estimated that this year's summer grain area is 387 million mu, 26 million mu less than the previous year, 6.3% less; the total output is about 190 billion jin, 8 billion jin less, 4% less Among them, the area of summer wheat is 316 million mu, 29 million mu, 8.4%; the output is about 164 billion jin, 10.7 billion jin, 6.1% The area of rapeseed harvested in summer in China is 104 million mu, an increase of 3.5% compared with the previous year, with a total output of 10.85 million tons, an increase of 970000 tons, an increase of 9.8%, showing a restorative increase Most of the summer oil production provinces have increased production 87y The main reason for the decrease of summer grain production is the decrease of sowing area; the second reason is the early stage of summer grain production The drought affected parts of North China, Huanghuai, southwest, northwest and East China, resulting in the decrease of per unit yield in Hebei, Sichuan, Guizhou and other provinces; the third reason is that since spring, there have been more rainy weather in Jiangnan and Jianghuai regions, and the soil moisture in some farmland is high, which affects the growth and production of summer grain In some provinces and cities, the per unit area production decreased According to the local agricultural departments, the grain and oil production structure is more reasonable this summer First, continue to expand the production of high-quality special varieties All regions continue to expand the production of high-quality special wheat and "double low" rape The area of high-quality special wheat for summer harvest in China is 107 million mu, 15 million mu more than the previous year, accounting for 34% of the total area, 7 percentage points higher than the previous year It is estimated that the output of high-quality special wheat is about 65 billion jin, 10 billion jin more than the previous year The area of "double low" rapeseed in summer is more than 71 million mu, an increase of 4 million mu over the previous year, accounting for 68% of the total area, a year-on-year increase of 2 percentage points; the output of "double low" rapeseed is more than 8 million tons, a year-on-year increase of 700000 tons Two, the regional production of superior agricultural products tends to be stable High quality special wheat and "double low" rape production continued to stabilize in the dominant production areas Hebei, Shandong and Henan provinces have 62 million mu of high-quality special-purpose wheat, accounting for 58% of the country's total, 7.8 million mu more than the previous year, accounting for 52% of the country's total increase The area of "double low" rape in Jiangsu, Anhui, Hubei, Hunan and Sichuan is 54.5 million mu, accounting for 77% of the total amount of the country, 3.3 million mu more than the previous year, accounting for 82% of the total increase of the country Third, the order area continues to expand According to incomplete statistics, this year's national summer harvest grain and oil crops "order" area reached more than 72 million mu, an increase of 12 million mu or 20% over the previous year Among them, there are more than 43 million mu of wheat, an increase of 7 million mu, an increase of 19%; 29 million mu of rapeseed, an increase of 5 million mu, an increase of about 21% At present, rapeseed harvesting has begun in South China, and winter wheat in most areas has entered the filling stage Some areas in the south of China are organizing and mobilizing the masses to harvest and dry the rapeseed in time due to the recent rain and the phenomenon of germination and mildew; the main wheat producing areas in the north are actively carrying out the late field management work focusing on the prevention of lodging, dry hot wind and pests At the same time, the agricultural and agricultural machinery departments at all levels are doing a good job in the prevention and control of SARS, and are also doing a good job in the preparation of wheat harvest, so as to minimize the impact of adverse weather on grain and oil production in summer 87y
