The compaction roller at one side ofthe screw has depth limiting and compacting functions, so that operating quality of the fertilizer-applying seeder body can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a no-tillage and fertilization seeder for straw returning to the field. Background technique [0002] In traditional agricultural activities, after crops are harvested, in order to sow the next season, the remaining straw is generally burned. However, burning straw may not only cause life and property safety problems, but also cause serious damage to the environment. Pollution. At present, the country has explicitly prohibited this kind of behavior. Manual cleaning is not only time-consuming and labor-intensive, but also may miss the best time for sowing, resulting in reduced crop yields and unable to make ends meet. Although special straw returning machines have appeared on the market, due to its The function is single, so it is necessary to fertilize and sow the farmland again, which not only wastes time and money, but also aggravates the compaction of the land, ...

[0002] In traditional agricultural activities, after crops are harvested, in order to sow the next season, the remaining straw is generally burned. However, burning straw may not only cause life and property safety problems, but also cause serious damage to the environment. Pollution. At present, the country has explicitly prohibited this kind of behavior. Manual cleaning is not only time-consuming and labor-intensive, but also may miss the best time for sowing, resulting in reduced crop yields and unable to make ends meet. Although special straw returning machines have appeared on the market, due to its The function is single, so it is necessary to fertilize and sow the farmland again, which not only wastes time and money, but also aggravates the compaction of the land, which is not conducive to the growth of crops
