What measures did the state take with regard to the price of dry maize in 2011 1 3

From January to May 2011, hybrid corn seeds were 10% year-on-year, due to the increasing demand for feed and processing in the downstream of corn, resulting in an upward trend of corn, causing seeds. Hybrid rice seeds**10%-17% year-on-year. Affected by abnormal weather, this year's hybrid rice seed production has been reduced to varying degrees, especially in Hainan, Hunan, Hubei, Jiangxi, Anhui, Jiangsu, Zhejiang and other places, and in the case of two consecutive years of seed production disaster and reduced yield, it is expected that the supply and demand situation of hybrid rice seeds in 2012 will be more tight.

The oversupply of hybrid corn seeds continues to ease. In 2010, the hybrid corn seed production area was 3.88 million mu, an increase of 550,000 mu compared with 2009, but due to abnormal climate, the seed production was reduced by 15%-20%, and a total of 100 million kilograms of seeds were produced. It is estimated that in 2011, the planting area of hybrid corn will be 100 million mu, and the amount of seed will be about 100 million kilograms, and the remaining 100 million kilograms will be more than 100 million kilograms, which is still in excess of supply, but the degree is alleviated compared with 2010.

The supply and demand of hybrid rice are basically balanced. In 2010, the hybrid rice seed production area was 1.5 million mu, Dan Hongsheng increased by 130,000 mu compared with the previous year, and was also affected by abnormal climate, the spring seed production was generally reduced, and a total of 100 million kilograms of seeds were produced, plus more than 100 million kilograms of effective inventory, and the total amount of seeds in 2010 was about 300 million kilograms; It is estimated that the planting area of hybrid rice in 2011 will be 100 million mu, and the amount of seed will be about 100 million kilograms, and the remaining 100 million kilograms will be planted, which is generally in a balance between supply and demand.

The cost of seed production continues**, and the downstream output crops** increase. In recent years, the cost of seed production per mu of hybrid corn in Northwest China has risen with the cost of land rent, agricultural materials, labor and grain prices, the cost of seed production per mu was 1200 yuan in 2004, increased to 1400 yuan in 2005, increased to 1500-1600 yuan in 2006-2008, and is expected to reach 2300-2700 yuan per mu in 2011, an increase of 500 yuan over 2010. In 2007-2008, the cost of hybrid rice seed production per mu in Hainan reached 1500-1700 yuan, and the cost of hybrid rice seed production per mu in Hainan reached 2300-2400 yuan, an increase of about 400 yuan over the same period last year.

It is expected that the seeds will continue to show a trend in the past two years.
