New Progress in No-tillage sowing Technology in China

??? A few days ago, a scientific research team led by Hu Zhichao, a researcher from Nanjing Agricultural Mechanization Research Institute of the Ministry of Agriculture, completed the project "key techniques and equipment for sowing in no-tillage and clean areas with full straw mulch in dry fields" and passed the evaluation of scientific and technological achievements in Beijing. The evaluation shows that the overall technology of the project is in the leading level in the world, which provides a strong technical support for promoting the return of all straw to dry land in China and solving the problem of straw burning.

??? According to the evaluation expert group, in view of the problems of poor smoothness, serious shelving and drying of traditional no-tillage sowing equipment under the condition of full straw mulching in dry land, the idea of no-tillage sowing in clean area covered with full straw was put forward. key technologies such as full straw mulching "sowing in clean area", shunt and uniform mulching of stubble, and anti-blocking of pressing and sliding group were invented. The technical equipment of sowing in no-tillage and clean area covered with full amount of straw was created, which provided powerful technical and equipment support for the prohibition of straw burning and the realization of fertilizer utilization in the field.

??? With the support of the National Peanut Industry Technology system, the Scientific and technological Innovation Project of the Chinese Academy of Agricultural Sciences, and the national scientific and technological support, Hu Zhichao's team has continued to tackle key problems and innovates. first, it has invented the mechanized no-tillage "clean area sowing" farming technology of "stubble straw cleaning, sowing in clean area and evenly covering straw" in full straw-covered land. Second, the technology of shunt regulation and uniform mulching of stubble was invented. The third is the invention of straw cleaning and overload monitoring and anti-blocking technology of press-slip group. The fourth is to create integrated no-tillage planter for corn, soybean and peanut covered with wheat stubble, and wheat no-tillage planter for corn stubble, rice stubble and cotton stubble. Jiangfan
