Six Key Points of Mulched Garlic Cultivation

Plastic film mulching cultivation of garlic can significantly increase production, and the economic benefit is very obvious. The following six links should be paid attention to in cultivation.

Soil preparation, fertilization and fine soil preparation, increase the application of organic fertilizer, 5000,7500 kg of mature organic fertilizer per mu. Plastic film mulching is generally covered with a small high border, with a width of 70 cm, a spacing of 20 cm, 4 rows per row, 15 cm between rows and 10 cm between plants.

Covering the plastic film is generally sowing before covering the film, the film should be covered strictly and tightly, so that the film is close to the ground, there is no gap, the film has no wrinkles, and the hole should be blocked with soil in time.

Scientific sowing is due to the prolongation of the growth period after plastic film mulching, so autumn sowing garlic can be sowed 5-7 days late, that is, it can be sown in the middle and last ten days of October, the density should be thinner, 35000-38000 plants per mu, and the suitable sowing depth of ridge cultivation is 3000cm.

After sowing and mulching at the seedling stage, the garlic cloves should be watered immediately to promote the garlic cloves to take root. When the seedlings are nearly emerging, water should be watered again to facilitate the emergence of the seedlings, break the plastic film and continue to grow. There is a bud that can not break the membrane, but the artificial breaking of the membrane can make the seedling exposed outside the membrane, and the smaller the mouth of the artificial broken membrane, the better. The seedling-promoting water was irrigated once in the seedling growth stage, and the frozen water was poured once during the overwintering.

During the period of flower bud and scale bud differentiation in the middle and later stage, the plastic film should still be protected and its heat preservation effect should be brought into full play, and it can not be removed until the early stage of bolting. Before bolting, topdressing should be heavy, 25 kg urea per mu, and keep the soil moist. Stop watering garlic 5-7 days before harvest to prevent garlic skin rot caused by soil moisture and affect storage.

Garlic bolts can be harvested when the white buds are harvested at the right time. About 20 days after bolting, the leaves of garlic withered and the pseudostem was soft, which was the suitable time for garlic harvest.
