Can buckwheat and naked oats be planted in Yuncheng area?

1. Buckwheat and naked oats can be planted in Yuncheng area.

Second, the climate in Yuncheng area

1, Yuncheng is affected by monsoon activities all the year round and belongs to the continental monsoon climate of warm temperate zone. Winter is controlled by Siberian dry and cold airflow, northwest monsoon prevails, and the climate is cold and dry; Summer is controlled by the warm and humid air flow in the Pacific Ocean, and the southeast monsoon prevails. The climate is characterized by high temperature, much rain, concentrated rainfall, heavy rain and thunderstorms. Annual average temperature 13.3℃, monthly average temperature -2.2℃, and July average temperature of 27.4℃. Sunshine hours are 2039.5 hours; The frost period is from late October of/kloc-0 to early April of the following year, and the frost-free period is 2 12 days.

2. The annual average precipitation (1956 ~ 2005) is 525mm, and the annual precipitation changes greatly. The annual maximum rainfall is 945.8mm, which occurs in 1958, and the minimum rainfall is 305.0mm, which occurs in 1997. The distribution of precipitation in the year is extremely uneven, with less in winter and spring, accounting for about 20% of the whole year, especially in summer and autumn, accounting for about 70% of the whole year; The precipitation in July and August accounts for about 40% of the annual precipitation. Affected by topography and climate factors, the regional distribution of precipitation is uneven, from 750 mm in the southeast to 500 mm in the northwest.

Third, the growth habits of buckwheat

1, buckwheat wasteland, roadside. Buckwheat likes cool and humid, and is not resistant to high temperature, drought, wind and frost. The accumulated temperature of 1000 ~ 1 500℃ can meet its heat demand. When the soil temperature is above 65438 06℃, the seeds can germinate in about 4 ~ 5 days. The optimum temperature for flowering and fruiting is 26 ~ 30℃. When the temperature is-1℃, the flowers will die, and even the whole plant will die at -2℃.

Buckwheat is a short-term crop. When the sunshine length is reduced from 15 ~ 16 hours to 12 ~ 14 hours, the growth period is shortened, and late-maturing varieties are more sensitive than middle-early-maturing varieties. Each plant can bloom more than 2000 flowers, but the seed setting rate is very low. Only about 10%, and the assimilation ability of leaves is weak, and flowers and fruits fall off seriously.

2. Buckwheat is a crop that needs more water, twice as much as millet and twice as much as wheat. Seeds need to absorb about 50% of their dry weight when they germinate. A lot of water needs to be consumed during flowering and fruiting. It takes twice as much water from flowering to harvest as from emergence to flowering. Flowering period is the peak of water demand. Its transpiration coefficient is generally 450 ~ 630. The relative humidity of air should not be lower than 30 ~ 40%.

3. Buckwheat is not strict with soil. The root system is weak and the seed jacking force is poor, so the soil layer is required to be loose to facilitate the emergence of seedlings and promote the development of roots. Reproductive growth is fast and fertility is strong, which is suitable for planting on newly reclaimed land. The soil acidity is required to be 6 ~ 7, and the soil with excessive alkalinity is not suitable for planting. For every 100 kg of buckwheat seeds, about 3.3 kg of nitrogen, 1.5 kg of phosphorus (P2O5) and 4.3 kg of potassium (K2O) were absorbed from the soil.

Buckwheat is a kind of crop sensitive to fertilizer. A well-fertilized stem can produce a large number of branches. Phosphate fertilizer can promote seed formation and increase nectary secretion. Use bees to assist pollination, thus increasing yield. Potash fertilizer is in great demand, but potassium chloride is easy to cause leaf spot.

5. Buckwheat requires a large temperature difference between day and night when flowering; It's cold at night and hot during the day. Sunny and windless, with many flowers and rich nectar secretion. Honey secretion and powder spitting began in the morning, the highest at noon, and then gradually decreased, and stopped after 14. However, due to the abundant sunshine on the plateau and the large temperature difference between day and night, honey secretion can be delayed until the afternoon. Honey is the most abundant in the foggy weather after rain. The optimum temperature for honey secretion is 25 ~ 28℃. When the temperature is lower than 25℃, honey secretion decreases with the decrease of temperature.

Fourth, the growth habits of naked oats

? Naked oats like cold and cool, drought-tolerant, salt-tolerant, short growth period, often wild in hillside roadsides, alpine meadows and wet places.
