[ China Agricultural Machinery Industry News ] On August 22, Sichuan Agricultural University, Sichuan Academy of Agricultural Sciences and other colleges and universities, scientific research institutions and extension departments related experts to Sichuan Ming Deng High-yield Rice Variety Research Institute located in Fengming Town, Pengshan District, Meishan City The high-yield demonstration of the new hybrid rice combination “Mingden No.7†and “Mingdeng No.11â€, which was planted in Lingjiao Village, was on-site manual acceptance, and the results of the production were: “Mingden No.7â€, dry yield of 817.2kg, “Ming On the 11th, "Acre is 725.lkg. On-site agricultural experts unanimously agreed that the two new varieties have good agronomic performance and yield, and the comprehensive traits are excellent. It is recommended to speed up the process of reviewing new varieties and promote the application as soon as possible.
The new hybrid rice combination "Ming Deng 7" has an output of 800 kg per mu.
It is understood that the Sichuan Mingdeng High-yield Rice Variety Research Institute was built by the farmer Chen Mingdeng of Fengming Town, Pengshan District, Meishan City. It was established by the Sichuan Provincial Civil Affairs Department and established a production research base in Pengshan District of Meishan City. Now the base has reached 300. mu. At present, the base has cultivated 21 hybrid rice varieties of Candid, Candied Rice, Japonica Rice and Two Lines, among which 6-7 are prominent in comprehensive traits, and the main quality indicators are in Grade 1 and 2 of the national standard. the above.
Through many years of trials, the Institute has shown that the “Mingdeng†series of rice exhibits high resistance to rice blast, sheath blight, bacterial blight and rice smut; the plants in the growing season are robust, mature, blue-yellow, and rice. The spikes are neat, the rate of emergence is high, the grain is slender, and the grain is dense; there is almost no lodging.
Chen Mingdeng, dean of the institute, told reporters that the rice varieties developed from the growth to the harvest do not need to be fertilized and sprayed with pesticides. Instead, they plant Chinese herbal medicines such as Chuanxiong and Alisma in the fields. The rot is directly used as organic fertilizer to improve the soil. It can also prevent pests and diseases and maintain the ecological health and safety of food.
The reporter learned that Sichuan Province is one of the provinces with large rice planting area in China. However, due to regional and climatic factors, most areas are not suitable for promoting rice with high yield per mu, while the area of ​​conventional rice and local rice is The production is not high, and the average yield per mu is 520 kg.
Sichuan Province agronomist Wang Zhitang believes that the research technology of Sichuan Mingdeng High-yield Rice Variety Research Institute has reached the domestic leading level, and the mature period of some high-product varieties in Mingdeng is about 135 days. After the transfer of rural labor, the production of agricultural mechanization has provided a powerful force. Variety support.

Mild Steel Plate
Mild steel is a type of carbon steel with a low amount of carbon – it is actually also known as [low carbon steel." Mild steel is not an alloy steel and therefore does not contain large amounts of other elements besides iron; you will not find vast amounts of chromium, molybdenum, or other alloying elements in mild steel. Less carbon means that mild steel is typically more ductile, machinable, and weldable than high carbon and other steels, however, it also means it is nearly impossible to harden and strengthen through heating and quenching.
Mild steel sheet plate is so versatile. It is tough, strong and stiff. It is ideal for welding and painting, can be easily machine cut and drilled and is magnetic. Our customers have used it for myriad applications including automotive repairs, engineering patch up jobs and many other DIY projects.
