Garlic cultivation technology
Garlic is a crop that likes coolness, needs sufficient light, likes moisture and fears dryness. It is rich in humus and is fertile, loose and breathable, and can retain water. Soil with strong drainage is suitable, and sandy soil is filled with garlic for cultivation. It has a strong spicy taste, loose texture, and is not resistant to storage.
1. Soil preparation and fertilization
1. Soil preparation and bordering: Choose loose and breathable soil with easy drainage and irrigation, carry out intensive tillage and fine rake, and level the soil for bordering.
2. Application and use of base fertilizer: Because garlic is a shallow-rooted crop, it has weak fertilizer absorption capacity and has high requirements for the quality of base fertilizer. Full-effect and high-quality organic fertilizers are mainly used. Generally, 3,000 kilograms of organic fertilizer per mu are applied. Fertilizer, 40 kilograms of three-element compound fertilizer or 15 kilograms of urea plus 20 kilograms of diammonium phosphate. The fertilizer should be even and applied to the soil in advance to avoid fertilizer damage.
2. Sowing
1. Optimal sowing time and seed quantity per mu:
According to the natural climate characteristics of our area, that is, the characteristics of garlic itself, in The appropriate cultivation season is better to be early rather than late, and try to extend the growth period of seedlings, which is conducive to the development of garlic sprouts and bulbs. From mid-August to the end of September, the sowing depends on the products required for planting (green garlic, garlic sprouts, garlic). The amount also varies, generally 300-400 jin per mu.
2. Selection and processing of seed garlic
Seed cloves are the main source of nutrition in the seedling stage of garlic. Their size and quality have a great impact on the formation of product organs. The bigger it is, the stronger the plant will grow, and the heavier the bulb will be, and the corresponding yield per mu will be higher. Therefore, it is necessary to select garlic cloves before sowing, and pick out white, fat, disease-free and disease-free garlic cloves as seed cloves.
3. Sowing method: The first method is to dig ditches to irrigate, plant garlic and then cover with soil, which is called wet sowing method. The second method is to drill multiple holes to plant garlic, then water it after pressing, which is called dry sowing.
4. Sowing density and depth
Garlic yield is composed of the number of plants per acre, the number of garlic cloves per plant and the weight of the cloves. Therefore, it is necessary to plant densely and reasonably. Generally, the seedlings per acre are maintained in 40,000 to 45,000 plants, that is, the spacing between rows is 25 × 4 cm, so as to obtain higher yields. The depth of sowing also affects its yield. Generally, the sowing depth is 3-4 cm. If it is too deep or too shallow, garlic seedlings will not easily emerge.
3. Field management
1. Water and fertilizer management
Garlic does not need more water and fertilizer during the germination stage. The seedling stage is the period of differentiation and establishment of garlic’s vegetative organs. , is also a critical period in the field. Irrigation should be properly controlled in the early stage of seedlings, and heavy watering should be done before winter to increase soil moisture. During the final stage of garlic withdrawal and the elongation stage of flower stems, these two years require more water and fertilizer. You should water more and topdress with water.
2. Cultivating and weeding Cultivating and weeding also play an extremely important role in the growth of garlic. First, it can loosen the soil and increase air permeability. Second, it can protect moisture, fertilizer and reduce soil fertility consumption
