Technical Field
The invention relates to the field of agricultural machines, in particular to a self-propelled straw returning and farming all-in-one machine.
Background
The straw returning can fertilize the land capability, and can also reduce the atmospheric pollution caused by straw burning and increase the fertilizer and the yield. The crop straw contains certain nutrients, cellulose, hemicellulose, lignin, protein and ash elements, has more organic matters and also has nutrient elements such as nitrogen, phosphorus, potassium and the like. The method for returning the straws to the field is an excellent method for making up the defects of long-term use of fertilizers. The agricultural ecological environment can be improved by returning the straws to the field. 80% of straws in rural areas are mainly subjected to combustion treatment, so that air pollution, traffic influence, soil surface layer coking and the like are caused, and sometimes fire disasters are caused. In addition, the agricultural ecological environment is also influenced by the random disposal of the straws. Therefore, the straw returning is beneficial to realizing the comprehensive utilization of agricultural wastes. In the process of returning the straws to the field, various straws are harvested and then preferably immediately ploughed into the soil to avoid water loss and difficult decomposition, and the straws are cut by a machine with enough horsepower, so that the decomposition of the straws can be accelerated, and the seeding and seedling emergence are not influenced.
The straw is firstly treated through the agricultural tractor drive straw clearance rubbing crusher at first among the traditional planting process, and later the seeding after utilizing agricultural tractor to drive the rotary cultivator rotary tillage once more, and above-mentioned mode can not realize returning the field completely of straw to the vehicle burden is big, and the activity duration is long.
