Garlic planting techniques

1. Soil preparation: Garlic likes fertile soil with good drainage performance. Continuous cropping should not be prone to pests and diseases. Before soil preparation, apply base fertilizer. Base fertilizer is generally fully decomposed farmyard manure plus appropriate amount of chemical fertilizer. Through soil preparation, the soil can become softer, which is beneficial to the growth of garlic. After clearing the land, you can make the bed. The width of the boundary is about 2 meters.

2. Seed selection: When selecting garlic seeds, choose varieties with strong disease resistance and high yield. When selecting seeds, choose garlic cloves with shiny surface and no scar, and the size is roughly the same.

3. Planting: After garlic seeds are selected, they can be planted. Before planting, seeds should be mixed to prevent pests and diseases. Generally, the row spacing is about 20 cm, and the plant spacing is about 16 cm. The soil after garlic packing is about 1 cm. After planting garlic, water it once. After watering for three days, you can choose whether to cover with plastic film according to the weather change. When covering with plastic film, remember to apply herbicide first to prevent weeds and garlic from competing for nutrients.

4. Fertilization and irrigation: As garlic overwinters, topdressing before garlic overwinters can make garlic take root and sprout quickly and improve its overwintering ability. Topdressing should be combined with irrigation, so that garlic can better absorb nutrients. In addition to overwintering fertilizer, when garlic turns green in the second year, green manure should be applied topdressing, which can promote the development of new leaves and roots of garlic and lay the foundation for high yield.

5. Weeding: Pay attention to timely intertillage weeding after watering garlic. Weeding process can not only eliminate weeds, but also avoid soil hardening. Because garlic likes soft soil, weeding can also promote the development of garlic.

6. Harvest: Garlic planted in autumn is generally harvested from early April to early May of the following year.

Garlic pest control

1. Leaf blight is a major disease in garlic growth. When the damage is serious, garlic is not easy to pick, which further affects garlic yield. The general prevention and control method is: in the early stage of the disease in mid-April, 75% chlorothalonil wettable powder 100g is used every 667 square meters, diluted with water and sprayed 1 times.

2. The occurrence of garlic maggots is not common in general years. For plots with heavy garlic maggots, soil preparation can be combined. The garlic maggots can be effectively controlled by applying 40kg plant ash every 667m2 when planting garlic in furrow. However, when garlic maggots are seriously harmful, drugs can be used to prevent them. The control method is to use 50% phoxim EC 100mL every 667 square meters in late April, dilute with water, and then pour the medicine into garlic roots.
