[China Agricultural Machinery Industry News] On December 8, the National Bureau of Statistics announced the food production in 2016. According to the website of the National Bureau of Statistics, according to the national statistical bureau's sample survey of agricultural production and management households in 31 provinces (autonomous regions and municipalities) and comprehensive statistics of agricultural production and operation units, the national grain sown area, unit area output and total grain output in 2016 as follows:


2016 national food production has been announced today
First, the national grain sown area is 11,3028.2 thousand hectares (16,954.23 million mu), a decrease of 314.7 thousand hectares (47.21 million mu) from 2015, a decrease of 0.3%. Among them, the grain [1] planting area was 94370.8 thousand hectares (14,155.62 million mu), which was 1265.1 thousand hectares (189.77 million mu) less than 2015, a decrease of 1.3%.
Second, the national grain output per unit area was 5452.1 kg/ha (363.5 kg/mu), which was 30.7 kg/ha (2.0 kg/mu) less than that in 2015, a decrease of 0.6%. The output per unit area of ​​grain was 5988.8 kg/ha (399.3 kg/mu), an increase of 4.8 kg/ha (0.3 kg/mu) compared with 2015, an increase of 0.1%.
Third, the national total grain output was 6,162.39 million tons (123.248 billion jin), a decrease of 5.201 million tons (10.4 billion jin) from 2015, a decrease of 0.8%. The grain output was 565.165 million tons (1130.33 billion jin), a decrease of 7.115 million tons (14.23 billion jin) from 2015, a decrease of 1.2%.
In this regard, Huang Bingxin, a statistician from the Rural Statistics Bureau of the National Bureau of Statistics, explained that the decline in grain output in 2016 was affected by the decrease in planting area and the decline in yield. In 2016, the national grain sown area decreased by 4.72 million mu compared with the previous year, and the production decreased by 3.4 billion jin due to the reduction of planting area, accounting for 33.2% of the total grain production reduction; the national grain output decreased by 7 billion jin due to the decline in yield, accounting for the reduction of grain production. The total amount is 66.8%.
The main reason for the reduction of grain planting area: In 2016, the localities responded to the contradiction between supply and demand of grain varieties, actively optimized the agricultural production structure and regional layout, appropriately reduced the corn planting area in non-predominant areas, and adopted “corn to soybean” and “grain to feed”. And measures such as “grain to oil” to adjust the agricultural planting structure.
The main reasons for the decline in grain yields:
First, the area of ​​high-yield crops is reduced. According to the statistics of edible kernel corn, the area planted with corn is 551 million mu, a decrease of 20.39 million mu from the previous year, a decrease of 3.6%. The soybean planting area of ​​low-yield crops was 108 million mu, an increase of 10.46 million mu from the previous year, an increase of 10.7%. In 2016, the average yield of corn was 398.2 kg, which was 3.3 times that of soybean. Only corn can be reduced to about 1.7 kg per mu.
Second, the national agrometeorological disasters were heavier than in the previous year, and some areas were seriously affected. Summer grain and early rice were reduced due to disasters. In the early stage of autumn grain growth, many areas in the south suffered heavy precipitation, and Hubei, Anhui and other places suffered heavy disasters. Some farmland were repeatedly flooded and crops fell heavily. From late July to mid-August, some areas in the south suffered from high temperature, which led to an increase in the rate of rice shelling. Different degrees of drought occurred in the northeast and northwest regions, which was unfavorable for later corn production and grain filling. According to statistics from the Ministry of Civil Affairs, in the first ten months of this year, the national agricultural disaster area was 397 million mu, an increase of 54.1 million mu over the same period of the previous year, an increase of 25.7%; the unrecovered area was 62.18 million mu, an increase of 17.19 million mu, an increase of 70.9%.

According to the characteristics of the process, there are two kinds of cyanide gold plating and cyanide gold plating: Jin Yuan. At present, the quality of gold plating is cyanide (potassium cyanide) gold plating is good, its color, adhesion, wear resistance are better than non cyanide gold plating. Function can increase the conductivity of the material. The appearance of gold plated layer, has high chemical stability, only soluble in aqua regia, insoluble in other acid. The valence of gold. The standard potential Au+/Au of monovalent gold is +1.68V, and the standard potential of trivalent gold is Au3+/Au at +1.50V. In the case of steel, copper, silver and its alloy matrix, the gold deposit is a cathodic coating.
Jin Yuankang gold plating layer good ductility, easy polishing, high temperature resistance, with good anti tarnish properties. Gold plating on the silver layer can prevent the discoloration of silver; gold alloy coating can show a variety of colors, it is often used as decorative coatings, such as plated jewelry, watches and parts, works of art, etc..
Jin Yuan Kang plated with low contact resistance, good conductivity, easy welding, strong corrosion resistance and good abrasion resistance (of hard gold), so the precision instruments, printed circuit boards, integrated circuit, shell, electric contact has been used.
