Ammonium sulphate is an excellent Nitrogen Fertilizer raw material and widely used as seed fertilizer,top dress and base fertilzier that is suitable for general soils and crops.It can provides ans equal balance of nitrogen and sulphur and help the crop grow vigorously,improve fruit quality and yield,enhance crop resistance to disasters.
Ammonium Sulphate is suitable for general crops and soils,but there`re still some points to note.
1. Cannot be contacted/mixed with alkaline substances
2. Cannot be applied on the same farmland for a long time
3. Not suitable for use on acidic soils

The first 126 MW gas turbine manufactured in China was the first of four 9E gas turbines that the South Steamship-GE complex won the bid in the national bundling tender. With the construction of the West-East Gas Pipeline Project and the development of the national economy, the gas turbine power station construction project has become China's key project dedicated to meeting the growing demand for electricity.
The ceremony was held at the South Steamship Factory. The National Ministry of Foreign Affairs (Li Ye, Deputy Director of the National Development and Reform Commission, President Lu Yanwei of the China Machinery Industry Federation) and Jiangsu Province (Deputy Governor Li Quanlin) and Nanjing (Executive Vice Mayor) Chen Jiabao) leaders attended the ceremony. The gas turbine will be transported to the Golmud Combined Cycle Power Plant in Golmud, Qinghai as part of a 200MW combined cycle power generation system.
The cooperation between South Steam Turbine and GE can be traced back to the early 1980s, when Nanqi Steam and GE cooperated to produce 6B series (42-46MW) gas turbines. Up to now, more than 60 sets of 6B series gas turbine sales contracts have been signed, of which 29 sets are exported, and the technical level is synchronized with the international level. The cooperation between Nanjing Steam Turbine and GE has provided a successful example for China to introduce and digest advanced technologies and comprehensively improve the manufacturing level of heavy gas turbines.
Under the organization of relevant ministries and commissions in China, in June 2004, Nanqi Steam and GE signed the 9E gas turbine technology transfer agreement, and then the two sides formed a consortium to bid for the China 9E gas turbine project and successively won the bid. On December 7, 2005, the Golmud project contract came into effect. On June 18, 2006, the first 9E gas turbine test station of the South Steam Turbine-GE Consortium successfully implemented the first ignition; on June 22, the whole machine passed the full speed. No-load performance test.
Shen Qun, general manager of the South Steam Turbine, commented: “The large-scale gas turbine is a major technological complete set of equipment developed during the 11th Five-Year Plan period in China. The first 9E gas turbine with a localization rate of 31.32% was completed and shipped, marking the South Steamship and The cooperation between GE and GE has reached a new height and has embarked on a road of cooperation, introduction, digestion and absorption, laying a good foundation for the rapid and healthy development of China's gas turbine industry."
GE is the world's leading supplier of power generation equipment, and the 9E grade gas turbine is a 50 Hz product that GE is widely used around the world. At present, GE has more than 382 installed 9E units worldwide, with a cumulative commercial operation time of more than 18 million hours.
“South Steamship has been working with GE for more than 20 years and is GE's earliest gas turbine manufacturer partner in China. The smooth assembly and delivery of the first 9E gas turbine fully reflects the partnership between GE and South Steamship. "This shows GE's long-term commitment and our local capabilities to provide China with reliable power generation products and technologies to support China's development and progress," said Wen Yuezhong, president of GE Energy China.
Under the concern of the relevant government ministries and the governments of Jiangsu and Nanjing, Nanjing Steam Turbine (Group) Co., Ltd. (hereinafter referred to as “Nanqi Steamerâ€) and the United States GE Energy Group (hereinafter referred to as “GEâ€) The first 9E gas turbine built in China was officially shipped in Nanjing on July 12.
