2, light: the growth of garlic can not be separated from the help of light. Under good lighting conditions, it grows well and produces more. Generally speaking, when the growth rate is the fastest, it needs to provide about ten hours of light every day to grow well. If it is short sunshine, its stems and leaves may grow in vain.
3. Watering: Garlic is a wet plant, and it is very afraid of drying. When the soil is dry, it needs to be replenished in time. Generally speaking, it is necessary to replenish water when it is half dry.
4. Fertilization: Fertilize garlic, mainly with base fertilizer. It is usually added in late September when the soil is turned over. The required topdressing is not too much, usually at the beginning of April, and some urea is used in moderation.
Second, the breeding skills 1, reproduction: mainly using the seed reproduction method. The first is to choose seeds. The size of seeds has a great influence on the success rate of reproduction and the subsequent yield. Sowing is best in late September or early October, and the temperature is about 17 degrees. The row spacing is controlled at about 20 cm, and the spacing between plants is at 16 to 18 cm. After sowing, water is needed.
2, pruning: in the growth period of garlic, it is also necessary to trim it properly. However, the number of times does not need to be too much. Pruning is a good auxiliary means, especially when diseases or pests occur. Other times, you can trim it in time, but don't be too strong.
Third, the problem diagnosis and treatment 1, diseases: There may be "leaf blight", which is the main disease of garlic and seriously affects the yield. It occurs frequently in April. Chlorothalonil can be used for prevention and treatment. There may also be "epidemic disease", which can be prevented by foscarnet, aluminum, manganese and zinc, and water and fertilizer need to be regulated.
2. Pests: The main species is "garlic maggots". Plant ash can be used to effectively prevent the harm of this pest. In severe cases, phoxim EC can also be used for prevention and control.
Other problems 1, toxicity: garlic plants are non-toxic and edible.
2. Can it be raised at home? Garlic can be grown at home. The operation is not troublesome, and you can also eat your own garlic. Moreover, it won't take up much space.
