Description

Technical Field

[0001] The utility model relates to the technical field of seed sowing, in particular to a sowing device suitable for sand ginger black soil. Background Art

[0002] The Shajiang black soil region is a major grain-producing area in Anhui Province and a key supply base for agricultural products such as grain, oilseed oil, and vegetables in my country. The soil is characterized by a low organic matter content, a shallow tillage layer, a heavy clay texture, and poor structure. The soil is muddy when wet and hard when dry, making it difficult to plow and harrow, resulting in a short farming season. The soil is high in clay, with montmorillonite being the predominant clay mineral. The clay minerals are abundant, rapidly expanding, and exhibit poor physical properties such as water retention and permeability.

[0003] On the other hand, long-term mechanical tillage has compacted and hardened the soil. This hardened sand ginger black soil makes sowing difficult and hinders rooting and germination. Therefore, a sand ginger black soil sowing device, designed to break up and turn the soil, addresses this issue, improving germination rates and contributing to the development of a 100 billion jin (approximately 100 billion jin) grain storage facility in the Jianghuai region.
