Wheat drill unit and planting method suitable for sticky and heavy soil in rice stubble field

Abstract

The invention discloses a wheat seed drill unit and a planting method suitable for sticky and heavy soil in rice stubble fields. Mechanism, vertical deep stubble breaking mechanism, ditch fertilization and seeding mechanism, floating soil covering suppression mechanism; horizontal shallow rotary tillage mechanism breaks stubble and crushes the shallow soil in the forward direction, and then the floating crushed soil leveling mechanism The soil surface is broken and leveled by profiling, and then the vertical deep stubble breaking mechanism breaks and breaks the shallow soil and deep soil; then the ditching and fertilizing device fertilizes while ditching, and the ditching and seeding device ditches while Seeding realizes the sowing method of sowing-fertilization-sowing interval and shallow sowing and deep fertilization; then, the floating soil covering device performs profiling soil covering on the grooves after fertilization and sowing, and finally the floating adjustable suppression device performs soil covering on the grooves after soil covering The surface is profiled and compacted to realize high-performance compound seeding operations in sticky and heavy soil in rice stubble fields.

Description

technical field [0001] The invention belongs to a wheat seed drill, and in particular relates to a single wheat seed drill suitable for sticky and heavy soil in rice stubble fields and a planting method. Background technique [0002] Wheat drill is one of the key equipment for crop planting in Jiangsu rice-wheat rotation area. During the wheat sowing period, there are many regional problems such as prominent stubble connection contradictions, difficult cultivation of sticky and heavy soil in rice stubble fields, difficulty in returning large amounts of straw to the field, and easy waterlogging in dry farming. At the same time, there are great differences in production methods and mechanization technologies in different regions, different stubbles, and different varieties of rice-wheat rotation areas, which further increases the difficulty of research on high-efficiency wheat seeding equipment. At present, there are few types of wheat seed drills suitable for Jiangsu rice-wh...

AI Technical Summary

Problems solved by technology

[0005] With the breakthrough of wheat precision seeding technology, combined seeding operation technology and the application and promotion of machinery and tools in our province, the problems of hanging grass blocking, racking and drying of traditional no-tillage seeding equipment have been completely solved. Wheat Some progress has been made in the research of seed drills, but the existing implements have insufficient adaptability to the sowing operation in sticky and heavy soil in rice stubble fields, and there are problems such as high operating cost, poor soil crushing effect, easy congestion, insufficient soil compaction, etc. The application of intelligent technology such as seeding technology and machine tool intelligence technology is still relatively low, and the operating efficiency still needs to be improved
