Wild garlic is a cold, long-day crop. After passing the vernalization stage, long days of sunshine are required to convulsion and promote the formation of bulbs. The roots of wild garlic are shallow and therefore wet, and the soil moisture is very strict. However, the soil type is not strict. The fertile loam rich in humus is the best, loose and breathable, and has good water and drainage performance. It is suitable for bulb growth and development. It is neat, good in quality and high in output. The optimum pH of the soil is 5.5~6.0. Wild garlic needs more fertilizer and is resistant to fertilizer, and the application of organic fertilizer has a significant effect on increasing yield. Garlic is the most popular organic fertilizer for nitrogen, phosphorus and potassium. Increasing the application of humus fertilizer can increase the yield and quality of garlic.
Cultivation time
Generally, wild garlic begins to grow when the soil is thawed in mid-March. It prefers cool climatic conditions, and begins to dormancy in the high temperature period in summer. After winter soil freezing, the small bulbs are used for wintering root storage in the underground. The spring and autumn seasons grow most vigorously, at a temperature of 8~ 18 ° C, soil moisture, sufficient light, fertile sandy loam growth is most suitable, generally in mid-April can be collected and eaten, can also be harvested in autumn in October.
Cultivation Techniques
Reproduction
(1) Seed breeding Wild garlic growth environment is relatively cool, so it can be planted in spring and autumn. In the spring sowing, the short-term plants grow slowly, and the harvest in the same year is low. The autumn sowing is carried out after the high temperature period in September, and the bulbs are wintering in the ground, and the spring is high in the second year.
(2) Bulbs Breeding wild garlic can be propagated by seeds or bulbs, or by small bulbs. In the spring and autumn, the small root garlic is dug up, and the small sub-sacs of the underground bulb can also be carefully opened at the root plate, so that each small bulb has an appropriate amount of fibrous roots, and then graded according to the size. In the prepared sorghum, the trench is ditched by 8 cm line spacing, planted at a distance of 5 cm, then covered with thin soil, and then re-sintered with a little pressure.
2. Cultivation techniques
(1) Fertilization with soil for soil preparation, fertilization before planting, applying 2000 kg of high-quality decomposed crude fertilizer per 667 m2, ploughing after ploughing to make a sorghum with a width of 1.2 m, and sprinkling 0.5 after pouring water. The centimeter thick fine soil is spread again. After sowing, cover the tidal soil with a thickness of 0.5 cm, and then cover the plastic film or straw to moisturize.
(2) Remove the cover after the seedlings are emerged. In the 2 leaf stage of the seedlings, the seedlings were planted at a distance of 2 to 3 cm, and weeding was carried out at the same time; in the 3 to 4 leaf stage, the seedlings were planted at a distance of 6 to 8 cm while weeding and watering.
(3) Field management is slightly yellow at the tip of the leaf after the 4-leaf stage. This is a sign of underground bulb expansion. At this time, it is necessary to strengthen the management of water and fertilizer, and apply 10 kg of urea per acre while watering. It can be harvested in the middle and late May, otherwise the wilting and yellowing will occur due to the high temperature plants entering the dormant period in summer.
3. Autumn broadcast management technology
Autumn sowing is generally carried out in August to September. It can be used for stripping or sowing methods and should be protected from high temperatures during the seedling stage. After the seedlings are released in autumn, it is necessary to prevent the accumulation of stagnant water. Before the winter, it is necessary to form strong seedlings, that is, the leaves are black and green and have grown 3 leaves and 1 heart. Before freezing, the frozen fertilizer should be poured, and 1000 kg of human excrement should be applied every 667 m2. When the temperature in winter is lower than 10 °C, the straw should be covered with the temperature drop. Slowly remove the straw and withered leaves during the spring thawing and then pour back the green water. By the middle of April, the quick-acting fertilizer can be applied to accelerate the vegetative growth, promote the tillering and expansion of the bulbs, and at the same time remove the extracted stems to control reproductive growth. You can enter the harvest period in mid-May.
The pests and diseases that occur in the process of planting garlic are similar to those of garlic. Therefore, the control measures of garlic pests and diseases can be used for prevention and control.
