The Nanjing Agricultural Mechanization Research Institute of the Ministry of Agriculture, the “Key Techniques and Equipment for Seeding in the Whole Field of Straw Covering and No-Tillage Areas in Dry Landâ€, recently passed the evaluation of scientific and technological achievements. The evaluation expert group believes that the overall technology of the results is at the international leading level.
According to researcher Hu Zhichao, the chief scientist of the project, whether it is farming time, cost saving, raising the multiple cropping index, or cultivating land for quality conservation, straw burning, and ecological protection, farmers generally expect that there is a kind of equipment that can be used to go down to the next time to complete the hoeing. No-till sowing. However, traditional no-till seeding equipment has serious problems such as poor smoothness, planting and drying.
The characteristic of this technology is a new mode of sowing and cultivation in the mechanized no-tillage area of ​​“grass straw clearing, clean area sowing, evenly covering strawâ€. The researchers also invented the shrub shunt regulation and uniform coverage technology, which effectively solved the problem of weak seedlings and seedlings caused by a large amount of straw mulching and uneven mulching in areas with heavy rain, and achieved uniform coverage of the mulch on demand. Insulation and protection, closed weeds, and can improve the efficiency of fertilizer efficiency.
The researchers also integrated the wheat, soybean, peanut no-till planter, corn glutinous rice, rice glutinous rice, cotton glutinous rice stalk covered wheat no-till seed drill, which solved the problem of hanging grass, blocking, planting, The problem of air-breeding technology has achieved uniform coverage of straw after sowing, providing powerful technical and equipment support for straw burning and realizing fertilizer application in the field.
Aluminum Grooved Tube is a kind of aluminum round tube which has inner threaded shape.The inner shape can increase the heat flow area thus the heat exchange rate can be increased.Aluminum Grooved Tube is widely used in air conditioning condenser,automobile radiators.Trumony provides high precision extruded round tube.The thinnest wall thickness of the Aluminum Grooved Tube is 3mm.
