Description
Technical Field
The invention relates to a garlic seeder, and belongs to the technical field of agricultural machinery.
Background
The garlic has rich nutritive value, edible value and medical value, is a raw material of a plurality of industrial products, is an important economic crop in China and has wide planting area. At present, garlic is mainly planted manually in China, but with the aging problem of the population becoming more serious and the shortage of rural labor force, the labor cost is increased continuously, and for the elderly rural labor force, long-term high-intensity labor not only affects the body health, but also affects the labor efficiency. The mechanical sowing instead of manual sowing is a development trend of garlic sowing modes in the future. The row spacing, the plant spacing, the sowing depth, the sowing time, the bulbar orientation, the ridge orientation and the like are the agronomic requirements of garlic sowing. Wherein row spacing, plant spacing, depth of planting, seeding time can be controlled through mechanized mode, and bulbil orientation and back orientation are the difficult problem of solving in the mechanized seeding, and bulbil can influence garlic head quality and transverse diameter down during the seeding to influence garlic output. However, the existing garlic sowing machines at home and abroad have fewer types and quantity, the garlic sowing machines at home and abroad can not meet the requirement of domestic agriculture, and the garlic sowing machines at home have the problems of reseeding, missing sowing, seed damage, high price, incapability of controlling the orientation of bulbil and the like during sowing. At present, a garlic seeder which meets the agricultural requirement of garlic seeding in China, has a seeding effect comparable to that of manual work and has a price accepted by farmers is lacked, so that the development of the garlic seeder with mature performance and low price has important significance.
