Cultivation techniques of garlic
Garlic is a crop that likes cold, light, humidity and dryness. Suitable for rich humus, strong water retention and drainage performance, loose and breathable soil, planting garlic-filled sandy soil, with strong spicy taste, loose texture and poor storage resistance.
First, soil preparation and fertilization
1. Soil preparation: Select loose and breathable soil which is convenient for irrigation and drainage, intensively plough and rake, and level the ridge.
Second, sow.
1, the best sowing date and the amount of seeds used per mu:
Prolonging the growth period of seedlings as much as possible is beneficial to the development of garlic bolts and bulbs. From mid-August to the end of September, according to the different products (green garlic, young garlic and garlic) needed for planting, the sowing amount is also different, generally 300-400 kg per mu.
2. Selection and treatment of planting garlic: before sowing, choose garlic cloves and pick out the white and fat garlic cloves that are free from disease.
3. Sowing method:
First furrow irrigation, garlic planting and soil covering are called wet sowing method. The second kind, planting garlic in multiple holes, watering after suppression, is called dry sowing.
4. Planting density and depth
Sowing depth also affects its yield. Generally, the sowing depth is 3-4 cm, and it is not easy to emerge if it is too deep or too shallow.
Fourth, on-site management
1, water and fertilizer management
Garlic doesn't need much water and fertilizer in the germination stage, and the seedling stage is the completion of the differentiation of garlic vegetative organs and the key period in the field. Irrigation should be properly controlled in the early stage of seedling stage, and water should be poured once before winter to improve soil moisture. At the end of garlic mother pumping, the flower stems are elongated. In the past two years, there are more requirements for water and fertilizer, so it is necessary to water more and topdressing with water.
2, intertillage weeding
Intertillage weeding also plays an extremely important role in the growth of garlic. On the one hand, it can loosen soil and increase air permeability; On the other hand, it can preserve soil moisture and fertilizer and reduce the consumption of soil fertility.
