The Hexi Corridor develops irrigated agriculture. The Hexi Corridor has an annual precipitation of only about 150 millimeters, and the surface is dominated by deserts and semi-deserts, but the use of snow and ice melt water from the Qilian Mountains for irrigation has made the region more developed for agriculture, with a wider area of greenery coverage. The Hexi Corridor is about 1,000 kilometers long from east to west and about 2-3 kilometers wide, with alluvial plains in the middle, and the central part of each plain is usually an oasis area, which runs through the desert and the Gobi, and where the rivers originate from the inland waterways of the Qilian mountainous terrain.

I. What agriculture to develop in the Hexi Corridor

1. The Hexi Corridor to develop irrigated agriculture. The climate of the Hexi Corridor is drier, the annual precipitation is only about 150 millimeters, the surface of the desert and semi-desert, but because of the Qilian Mountain ice melt water can be used as irrigation water, so it makes the region's agriculture is more developed, the greenery covers a wider area.

2, the region from east to west is about 1000 kilometers long, about 2-3 kilometers wide or so, most of the soil is loess (fan-shaped on the ground is mostly composed of gravel), the middle of the corridor for the alluvial plain.

3, the central part of each plain within the region is usually an oasis area, between the oasis runs through the desert and the Gobi, where the rivers all originate from the Qilian mountainous inland water system.

4, the region's average temperature in January is usually -8 ° C to -12 ° C, the average temperature in July is usually 20-26 ° C, the annual frost-free period is usually about 160-230 days.

5, in ancient times, the Hexi Corridor is a necessary route from Chang'an to the western region, it is the main transportation route between China's history of the Middle East and the West, so since ancient times is the land of abundance.

Second, the Hexi Corridor agricultural location conditions

1, location conditions

(1) flat terrain, ample water, the Qilian Mountains of ice and snowmelt and the Shiyang River, Danghe River and other rivers can provide irrigation water.

(2) Temperate continental climate, more desert, suitable temperature and sufficient light.

(3) Long history of agriculture, farmers have rich experience in planting.

2, the main crops

(1) flat oasis area

① grain crops: including barley, millets, corn, spring wheat, cereals, etc., but also a small area of planting potatoes, rice, sorghum.

② melon crops: including watermelon, blancmange, son melon and so on.

③ Oilseed crops: mainly including caraway.

④ Fruit trees: including apple trees, date palms, pear trees and so on.

2. Pre-mountain area

Mainly planted rye, oilseed rape, barley, peas, potatoes, broad beans and other crops.
