What are the two major problems commonly seen in garlic cultivation?
In recent years, in the main garlic-producing areas such as Jinxiang, Juye, Cangshan, Zhongmu, and Kaifeng, quite a few problems have arisen from a series of causes including continuous cropping, poor management, and unscientific fertilization. They can be summed up in 9 words: "yellow leaves, dry tips, dead seedlings, low yield." The author now introduces to the broad ranks of agricultural technology extension workers and garlic growers the causes of the two most headache-inducing problems that have appeared in garlic cultivation in recent years. Problem one: the garlic looks normal before winter, with a few yellow leaves and dry tips, but after green-up the garlic seedlings turn severely yellow.
