Crops suitable for planting in mountainous areas
The cold and wet ecological zone includes most areas of Yangxian County, Zhangxi 'an County and Weiyuan County and a few cold areas of Longxi County, Tongwei County and Lintao County. The crops planted are mainly winter and spring wheat, broad beans, potatoes, rape and other grain and oil crops, with an annual planting area of about 2 million mu. The natural conditions in this area are very bad, and the suitable farmland is distributed in the range of 1800 ~ 2600 meters above sea level, with an average annual temperature of 5. IC and the average annual precipitation are 614.5 mm. Natural disasters are frequent, with low temperature, freezing injury, hail and flash floods occurring alternately, and diseases, insects, grasses and rats are seriously harmful.
Cold-tolerant fruit trees, such as peaches, pears and grapes.
Crops suitable for planting in mountainous areas
Mountain fruit
Fruit is the general name of fruits and seeds of some edible plants, which has health care functions such as lowering blood pressure, delaying aging, losing weight, caring skin, improving eyesight, resisting cancer, lowering cholesterol and supplementing vitamins. There are many fruits suitable for planting in mountainous areas, such as apples, raspberries, kiwis, watermelons, mulberries, plums and pears.
grain crops
Grain crops include wheat, rice, corn, oats, rye, barley, millet, sorghum and corn, accounting for more than half of the world's grain. Because mountainous areas are generally dry, sweet potatoes, sorghum, buckwheat and corn should be chosen when choosing food crops.
Tea planting
Tea trees like warm and humid climate. Generally, the soil is sandy loam with a thickness greater than 1m, no limestone, good drainage, organic matter content greater than 1 ~ 2%, and good air permeability, water permeability or water storage performance. At the same time, the terrain conditions mainly include altitude, slope and aspect. With the elevation, the temperature and humidity have obvious changes. In a certain height mountain area, abundant rainfall, abundant clouds, high air humidity and high diffuse light intensity are beneficial to the growth of tea trees, but the higher the better, the water-soluble fertilizer of Fuwo Shiwo leaves can be used to improve the quality of tea.
Medicinal materials suitable for planting in alpine areas
Glycyrrhrizae Radix, Radix Astragali, Flos Lonicerae, Radix Ophiopogonis, Herba Plantaginis, Herba Houttuyniae, Radix Asparagi, Radix Salviae Miltiorrhizae, Radix Scrophulariae, Radix Rehmanniae, Fructus Gardeniae, Cortex Acanthopanacis, Fructus Lycii, Radix Isatidis, Folium Eriobotryae, Radix Isatidis and Juncus Junci.
Climatic characteristics of alpine mountain areas
The characteristics of alpine mountain areas are as follows: First, the climate is relatively cold, and the effective accumulated temperature is low during crop growth. In the fifth accumulated temperature zone ≥ 10℃, the active accumulated temperature is only 1900 ~ 2 100℃, while the sixth accumulated temperature zone is below 1900℃, even only1700 ~/kloc-in many places. Second, the growth period is short, and first frost is early. Generally, the frost-free period is only about 1 10- 120 days in places with good climate, and only 80-90 days in places with poor climate. Third, the microclimate is obvious. The climate of the same village is not only very different between the mountain and the foot of the mountain, but also the temperature on the south slope and the north slope of the same land is very different. Fourth, the damage of low-temperature first frost is frequent, generally 3 ~ 4 years 1 time. We should fully understand these characteristics and seek advantages and disadvantages in agricultural production.
