1、 Definition (Basic Concept):

The strip tillage mode covered with corn straw is a new protective tillage technology, which realizes the return of straw, deep loosening of sowing belt, strip rotation, compaction, and fertilization in one go.

The use of lightweight seeders or manual seeders during sowing solves the problems of soil compaction, weak drought resistance and moisture retention, and corn lodging in traditional sowing methods.

2、 Technical points:

1Straw returning, deep loosening and shallow rotation, synchronous suppression.

2Using this technology to cultivate seedlings with uniform and strong growth can solve the problem of low temperature seedling growth in some areas.

3Full straw mulching and returning to the field, improving soil organic matter, protecting black soil, and protecting the environment.

4Cost saving: Traditional farming costs1500-1700first/Hectares, using corn stover mulching and strip tillage technology, operating costs, large ridges and double rows260-300first/Hectares, large ridges, and four rows300-350first/Hectares, average cost savings1000first/More than hectares.

5Increase yield: On the basis of protecting the environment, achieve high and stable yield, cost savings, and efficiency improvement of corn, with an average increase in yield10%about.

6Implemented the protection of black soil through fallow rotation.

7Save fertilizer15%.

3、 Precautions and technical essentials:

1、 Cold and cool low-lying land: high ridges, deep loosening, deep plowing and shaping, light compaction, autumn operation.

2In hilly and arid areas, rotary tillage ridges are raised above ground level3-4cmJust enough (the height of the rotary tillage ridge can be adjusted by the depth limiting wheel), achieving deep loosening, shallow tillage and shaping, compacting and flattening the sowing belt, and maintaining moisture and drought resistance.

4、 Machine features:

1It can complete processes such as straw cutting, rotary tillage, seeding belt sorting, and compaction in one go.

2A clean and flat sowing belt is formed on the land cultivated by a strip tiller. When sowing, achieve consistent sowing depth, high uniformity of seedling emergence, and achieve uniform and strong seedlings.

3High homework efficiency, time-saving and labor-saving, efficient double row operation with large ridges40-60mu/10Hour, Big Ridge Four Rows80-120mu/10Hour.

4The principle is simple and clear (easy to accept), the operation difficulty is low (easy to master), the strip tillage equipment is simple (easy to operate), the ridge spacing adaptability is strong (easy to implement), and farmers spontaneously accept it (easy to promote).
