A, different distribution areas

1, buckwheat: origin and distribution of Allium originated in China, China since ancient times cultivated. According to records of China Yin Tang, that is, planting and eating habits. China's Jiangxi, Fujian, Zhejiang, Hubei, Hunan, Sichuan, Yunnan, Guizhou, Guangdong, Guangxi and other provinces are planted.

2, garlic: native to the western plateau of Asia, now the main source is Henan, Shandong, Jiangsu and other provinces.

Second, the appearance of different

1, buckwheat head: fibrous roots stringy, 6 ~ 17. With discoid shortened stems. Leaves tufted, slender, hollow, triangular cross-section, dark green and slightly greenish powder, slender and soft and easy to fall.

Tillers occur during the growth of the plant, each tiller has 3~8 leaves, the base of the leaf sheath expands into a small underground bulb, a bulb planted, can tiller to produce 10~20 small bulbs, expanding bulbs for short fusiform, transverse stems of 1~2cm, a single bulb weighs 8~12g, color white or light purple, bulbs are mainly for soaking or pickling. bloom in July~August, the flower stems are terete, solid, umbellate, with 10~10g, with a few leaves and a small leaf. Umbels with 10~25 flowers, pale blue-purple or white, smaller. Cultivars are mostly tetraploid, do not bear seeds, and are propagated by bulbs.

2, garlic: garlic for stringy shallow root system, no main root, the main root group is distributed in 5 ~ 25cm in the soil layer, spread across the diameter of 30cm. in plant morphology, the bulb itself is developed from the metamorphosis of the branch, its internodes shortened - "bulb disk", the base and edge of the stem disk bearing a bulb, the bulb is a small, light blue or white, the bulb is a small, light blue or white. The base and margins of the disk bear the root system, on which grow the primordia of leaves and buds.

After bud differentiation, the terminal buds form flower shoots, and the lateral buds expand to form garlic cloves. Garlic reproduction is asexual, and the reproduction organ is a lateral bud, the bulbous bud, on the mother. An adult garlic plant consists of roots, pseudostems, leaves, flowering shoots, bulbs and so on.

Three, the growth of environmental requirements

1, buckwheat: buckwheat like moist and cool climate, the growth of 15 ~ 20 ℃, the formation of bulbs in the spring under the conditions of long sunshine, temperatures of 30 ℃ or more, then dormant over the summer, tolerate low light, intolerance of bright light, suitable for fruit and mulberry intercropping; 10 ℃ below the slow growth.

Birth period of 270 days. Buckwheat head wild traits are obvious, the demand for soil and sunlight is not strict, a variety of soils can be planted, but well-drained loose and sandy loam is good, afraid of waterlogging, afraid of water, relatively drought-resistant, strong absorption of fertilizer. Although it can be cropped, but the rotation of fast-growing, high yield, excellent quality. Buckwheat head is also called buckwheat column, for the lily family onion can form small bulbs of perennial rooted herbs, 2 years old.

2, garlic: garlic prefers cool, more tolerant of low temperatures. Require higher sunlight and high temperature to promote flower buds and bud differentiation. In addition, garlic growth to sandy loam soil is the best, in the sandy soil growth of garlic spicy flavor, but the texture is loose, intolerant of storage. Garlic root shallow, root hairs, root system to absorb water, fertilizer capacity is weak, so not drought-resistant, in different reproductive period, garlic on the soil moisture requirements vary.

The budding period requires higher soil humidity, to promote root germination; seedlings can not be too much water, to prevent seedlings from growing, to promote the longitudinal growth of the root system; after the retreat of the mother, the bulb buds and flower buds differentiation period requires higher soil humidity; bulb expansion period, the soil humidity should be lowered, to avoid bulb skin rot black
