The yield per mu of peanuts increased by nearly half in more than three years of deep cultivation

"Last October, a foreigner came to my field to look at peanuts. He saw that the peanuts grew so well and began to study with a pile of peanuts." The foreigner, said Yu Minggang, a farmer in Liangcun Town, Gaotang County, Shandong Province, is the chief expert of the International semi-drought Research Group.

Chief expert, what are you doing in the village? He came specially to study peanut planting technology.

Gaotang County belongs to the old route of the Yellow River, and farmers have always had the habit of growing peanuts. Output was relatively low in the past, but it has increased greatly in recent years. Feng Ning, head of the planting Management Section of the County Agricultural Bureau, said that this is due to the implementation of the central financial peanut subsidy project, the demonstration and promotion of supporting techniques for single-grain precision sowing and high yield of peanuts, and the realization of full-process mechanized production.

This year is the fifth year of the implementation of peanut subsidy program in Gaotang County, and the third year of demonstration and promotion of high-yield matching techniques for single-grain precision sowing. In the past three years, the average per unit yield of peanuts has reached 427.3 kg per mu, an increase of 47.3% over the county's average annual yield, and the average benefit in recent years has reached more than 1100 yuan. The increase in yield has promoted the expansion of the planting area, and the perennial planting area of peanut in the county has been maintained at 100000 mu in recent years.

Wang Hongfeng, a peanut expert from the county's agricultural bureau, told me: "since the county undertook the peanut seed subsidy program in 2011, the agricultural bureau has continuously strengthened its ties with universities and scientific research institutes, established a 'scientific and technological Internet', and attracted a large number of scientific and technological personnel."

"what I planted last year was Huayu 22, with an output of 900 jin per mu. I used to keep my own peanut seeds, but the yield was only about 600 jin, and the seeds were not full and difficult to sell." Li Hongmu, a big peanut grower in Liangcun Town, Gaotang County, said to the author excitedly. Since the county made great efforts to promote the cultivation of improved varieties of peanuts, peanuts have increased by 100,200 jin per mu just because of the use of improved varieties.

In order to promote the development of peanut industry as soon as possible, in 2012, the county's Agricultural Bureau funded the purchase of two seeders, free services, focusing on demonstration. Today, the county has more than 40 sowing machines and more than 30 harvesting machines. The county agriculture bureau is in charge of the peanut project, which boldly improves the seeder and solves the bottleneck problem of "high-yield matching technology of single-grain precision sowing of peanuts".

"I've been growing peanuts for more than 20 years. In the past, they were all planted in pits, which was time-consuming and labor-consuming, and the efficiency was too low. In the end, it was sown with artificial strips, and relatively quickly, I had to plant more than 30 mu of land for three or four days. Since the county got a peanut seeder the year before last, the sowing speed is fast and the quality is good. " Gaotang County Qingping Town peanut grower Duan Zhixing told the author.
