Tartary buckwheat is not buckwheat.

1. Different shapes:

1. Buckwheat: upright stems, 30-90 cm high, branched above, green or red, with longitudinal ribs, hairless or on one side There are papillary projections along the longitudinal edges.

The leaves are triangular or ovate-triangular, 2.5-7 cm long, 2-5 cm wide, apex acuminate, base heart-shaped, with papillary protrusions along the veins on both sides; the lower leaf has a long petiole, and the upper part is thicker. Small and nearly sessile; stipule sheath is membranous, short cylindrical, about 5 mm long, with an oblique apex, no hairs, and is easy to break and fall off.

2. Tartary buckwheat: upright stem, 30-70 cm high, branched, green or slightly purple, with thin longitudinal ribs, papillary protrusions on one side, wide triangular leaves, 2-7 long cm, both sides have papillary protrusions along the veins, the lower leaves have long petioles, and the upper leaves are smaller with short petioles; the stipules are oblique, membranous, yellowish brown, about 5 mm long.

2. Different growth habits:

1. Buckwheat: grows in wasteland and roadside. Buckwheat likes a cool and humid climate, is intolerant of high temperatures, drought, and strong winds, is afraid of frost, likes sunshine, and needs more water.

2. Tartary buckwheat: Tartary buckwheat likes shade, dampness and coolness. It is mostly planted in high mountain areas and is distributed vertically at an altitude of 1200-3500m.

3. Distribution in China:

1. Buckwheat: Domestic distribution: Generally speaking, buckwheat in my country is mainly distributed in Inner Mongolia, Shaanxi, Gansu, Ningxia, Shanxi, Yunnan, Sichuan and Guizhou, followed by Tibet, Qinghai, Jilin, Liaoning, Hebei, Beijing, Chongqing, Hunan, Hubei and other regions.

2. Tartary buckwheat: 80% of Chinese tartary buckwheat is concentrated in the Yunnan-Guizhou Plateau, the Qinghai-Tibet Plateau, Gannan, Gansu, the hills and mountains of the Wuling Mountains of Hubei and Hunan, and the southern foothills of the Qinba Mountains.

Preparation before sowing:

Tartary buckwheat has strong adaptability to soil, but it is suitable for soil rich in organic matter, good structure, sufficient nutrients, strong water retention, good aeration, and low acidity. It grows on soil with a pH of 6 to 7. Buckwheat has weak root system, large cotyledons, and poor ability to support the soil. Suitable soil and correct farming play an important role in the germination, emergence, growth and development of tartary buckwheat.

For land preparation, deep plowing should be carried out after the previous crop is harvested. Deep plowing increases the mature soil layer and improves soil fertility, which is beneficial to water storage and moisture conservation, prevents soil moisture from evaporating, and reduces the harm of diseases and insects to bitter crops.

Buckwheat seed selection and sowing, the quality of the seeds directly determines the growth status and final yield of buckwheat. With the development of agricultural technology today, seed breeding technology has been perfected, and various high-yield, high-quality seeds with strong resistance have been cultivated.

When planting buckwheat, you must choose suitable high-quality seeds, and then treat the seeds before sowing. Treated seeds can increase the germination rate, enhance vitality, improve resistance to diseases and insect pests, and ultimately increase yields. Purpose. When sowing, you must consider the soil moisture and climate environment, and choose a suitable sowing time. Buckwheat is generally sown in mid-to-late June.

The sowing method should be determined according to the specific variety and land conditions. You can choose drill sowing, on-demand sowing, broadcast sowing, etc. In areas where conditions permit, try to use mechanized operations to improve efficiency?
