How many garlic plants are needed for one mu of land and what is the most suitable garlic planting density

1. Garlic planting row spacing and garlic planting amount per mu

Early-maturing garlic varieties, which mainly produce garlic stalks, generally have shorter plants, fewer leaves, narrow leaves, and shorter growth periods. The suitable density is 50,000 plants per mu, plant spacing 7-8 cm, row spacing 14-17 cm, per mu The amount of seeds used is 75-100 kg; the late-maturing varieties of garlic, which are mainly producing garlic, generally have taller plants, more leaves, wider leaves, and correspondingly lower density. The suitable density is 20,000 to 30,000 plants per mu, plant spacing It is 8-11 cm, the row spacing is 20 cm, and the seed quantity per mu is 120-175 kg; if the garlic sprouts and garlic heads are combined, the suitable density is 30,000 to 40,000 plants per mu, and the plant spacing is 6-8 cm. It is 20 cm, and the amount of seed per mu is 150-200 kg.

At the same time, garlic cloves should be sown thinly, and small garlic cloves should be sown densely; varieties with open leaves should be sown sparsely, leaves with upright and compact leaves should be sown densely; fertile fields should be sown thinly, and fields with poor soil should be sown densely; Garlic planted with plastic mulching should be thin, generally about 30,000 plants per mu; for export garlic production should be thin, generally 25,000 plants per mu. Early-maturing red-skin garlic planted in spring is 50,000 to 60,000 plants per acre, and dog tooth garlic is 50,000 plants per acre.

2. The depth of garlic sowing

If the garlic is too deep when sowing, it will be unearthed late, the seedlings will be weak, and the swelling of the bulb will be inhibited and the yield will be reduced. As the saying goes, "deep onion and shallow garlic", it shows that garlic is suitable for shallow sowing. However, if garlic is planted too shallowly, it is easy to lift the garlic cloves out of the ground after rooting, or the garlic cloves are very close to the ground surface. Under the influence of sunlight and high temperature, the garlic heads will become red in the early stage, the garlic skin will harden, which will affect the development and easily cause the garlic to crack. Reduce the quality of garlic. This phenomenon is called "jumping garlic". In order to avoid "jumping garlic", you should pay attention to timely sowing. After sowing, appropriate suppression, combined with cultivating and weeding and clearing the furrow, cultivate soil. The thickness of the soil is generally 3 to 5 cm.
