Methods and key technical points for rational close planting of garlic

How should garlic be rationally close-planted? Before sowing, the planting density must first be determined, that is, the number of plants per mu. According to trials in the Cangshan garlic production area, on plots with medium to high production levels, planting 30,000 plants per mu yielded 686.7 kg of fresh garlic bulbs; planting 40,000 plants per mu yielded 920 kg of fresh garlic bulbs, a 33.9% increase over planting 30,000 plants; planting 45,000 plants per mu yielded 526.7 kg of fresh garlic bulbs, a 23.3% decrease. The trials found that when the number of plants per mu exceeded 40,000, although the yield increase was significant, the commercial quality declined, and more seed was used, so the economic benefit was not high. Therefore, on plots of medium fertility, a row spacing of 20 cm and a plant spacing of 9.5 cm, with 35,000 plants per mu, is relatively suitable. For high-yield cultivation on soil with high fertility, a large amount of fertilizer, and a high level of management, a row spacing of 20 cm and a plant spacing of 9.5-8.3 cm can be used, with 35,000-40,000 plants per mu.
