Wheat-corn multiple crop rotation is an important planting mode in the Huanghuai and northern winter wheat regions of my country, and plays an extremely important role in ensuring national food security. Returning wheat and corn stalks to the field is an important technical measure to improve soil fertility, improve soil physical structure, and increase grain production in this area. However, in the current production, corn stalks are mostly returned to the field in full, and the amount of straw is generally large. The common wheat no-tillage planter sows immediately after one-pass rotary tillage or full rotary tillage, and it is difficult to completely remove corn stalks from the seedling belt or fully mix with the soil. Mixing, it is easy to cause congestion during the sowing process, which seriously affects the quality of sowing, reduces the emergence rate and uniformity, and also causes uneven ground, affects the growth and development of wheat, and even reduces the grain yield. The latest research shows that the depth of base fertilizer application has a significant impact on fertilizer efficiency and the absorption and utilization of wheat at each growth stage, and the distribution of different types of fertilizers at different soil depths is conducive to the exertion of their respective fertilizer effects. There is an invention patent "A Wheat Subsoiling Rotary Tillage Layered Fertilization and Belt Spreader" (CN201510006429) applied for protection of the subsoiling layered fertilization device, which has the functions of applying fertilizer below the rotary tillage layer and spreading fertilizer at equal depth The structure of the middle and lower parts in the rotary tillage layer; the subloose layered fertilization shovel applied for protection in the existing utility model patent "no-tillage subsoiling and layered fertilization wheat planter" (CN201420683858) is located behind the rotary tiller, and its bottom is larger than The bottom of the rotary tiller is 8-15 cm lower, and the fertilizer discharge pipe is on the back side of the subsoiling layered fertilization shovel.

However, the above-mentioned patents are difficult to solve the problems of uneven mixing of soil and straw and easy congestion due to the large amount of straw returned to the field, and lack of precise and intelligent proportional layered fertilization devices and wide seedling width with high seed uniformity. Drilling devices are difficult to meet the needs of large grain growers for multi-functional soil preparation, fertilization and sowing integrated machinery in the intensive, large-scale and standardized production of grain crops.
