Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of small agricultural machinery, and particularly relates to a post-film sowing and film covering auxiliary garlic seedling film breaking and emergence device. BACKGROUND

[0002] China is the world's most important garlic producing country, and the annual planting area of garlic is about 12 million mu, accounting for more than 50% of the world's garlic planting area. Garlic is a labor-intensive industry, and a large amount of labor is consumed in each link such as garlic sowing, field management, harvesting and airing. Taking the main garlic planting type of head garlic in China as an example, the planting density is about 30,000 plants per mu, and about 20% of the garlic seedlings cannot break the film by themselves under the traditional planting mode, and need artificial assistance to break the film. The artificial assistance to break the film includes single plant film breaking by hand-held garlic hook and auxiliary film breaking by pressing device, and the above-mentioned methods need to be carried out after the garlic sprouts, which is easy to cause delay, and in addition, due to the consistency problem of garlic emergence, the above-mentioned film breaking work often needs to be repeated many times, which is time-consuming and labor-consuming. Therefore, a pre-emergence auxiliary film breaking device suitable for the current garlic planting mode is needed to solve the above-mentioned problems. SUMMARY
