ActiveCN107593228BNutritiousLow effective utilizationFertilising methodsCultivating equipmentsPotassium nitrateManganese sulphate
The invention discloses a selenium-enriched Chinese chestnut production method and belongs to the technical field of Chinese chestnut planting. The selenium-enriched Chinese chestnut production methodcomprises the following steps that 1, a selenium-enriched nutritional solution A is delivered in a flowering period, wherein the selenium-enriched nutritional solution A is prepared from selenium mineral powder, fulvic acid, a potassium hydroxide solution, ammonium phosphate and potassium nitrate; 2, a selenium-enriched nutritional solution B is delivered in a fruit swelling period, wherein the selenium-enriched nutritional solution B is prepared from selenium mineral powder, potassium carbonate, sodium humate, selenized carrageenan, manganese sulfate, citric acid chelated iron, citric acid chelated copper and water. The selenium-enriched Chinese chestnut production method also comprises the steps of fruit processing after picking. Tree bodies directly absorb the selenium-enriched nutritional solutions in a nutritional solution delivery mode according to the characteristics of Chinese chestnuts, the selenium utilization rate can be improved, the selenium content in the Chinese chestnuts can be increased, the use amount of selenium fertilizers or the selenium-enriched nutritional solutions can be decreased, the cost can be reduced, the selenium content of Chinese chestnuts producedby adopting the method is high by cooperating with the selenium-enriched nutritional solutions for later Chinese chestnut fruits, and the daily selenium supplementing demand of people can be met.

Turbine supercharger with cooling water jacket
ActiveCN103114880BReduce the temperatureLow effective utilizationGas turbine plantsEngine componentsTurbochargerFuel oil
The invention relates to a turbine supercharger. The turbine supercharger with a cooling water jacket comprises a turbine motor shaft, a turbine motor turbine, and a turbine motor scroll, wherein the turbine motor is installed on the turbine motor shaft, the turbine motor turbine shell covers outside the turbine motor turbine shell, an air inlet and an air outlet are formed in the turbine shell, the water jacket is arranged inside the turbine motor turbine shell, a water inlet and a water outlet are formed in the water jacket, the water inlet is placed in one side, facing the air outlet, of the water jacket, and the water outlet is placed in one side, facing the air inlet, of the water jacket. The turbine supercharger where the water jacket is installed on the turbine motor turbine shell, and water inside the water jacket and the turbine motor turbine shell can conduct highly-efficient heat exchanging resolves the problems that effective use ratio of fuel oil is low and light materials being used in the turbine motor turbine shell for manufacture is restricted because of high temperature of the turbine motor, the fact that the light materials cannot be adopted in the turbine motor for manufacture can cause that the turbine exchanger is weight, and therefore the effective work of a motor is lowered.
