玉米是一种高产作物。在高温、强光、低二氧化碳浓度下,它光合强度比小麦、水稻高出40％左右。由于长期的自然和人工选择,玉米能够适应广大地区栽培。通常以气温≥10℃的活动积温达2000—2800℃和降水量达350—500毫米作为种植玉米的基本气候条件。然而,盆区≥10℃活动积温达4500℃以上,玉米生长期间的降水量为500—600毫米,表明盆区水、热资源丰富,很适宜种植玉米。
Corn is a high-yield crop. At high temperature, high light, low carbon dioxide concentration, its photosynthetic intensity than wheat, rice about 40% higher. Due to long-term natural and artificial selection, maize can be adapted to cultivation in vast areas. Usually the temperature of ≥ 10 ℃ activity accumulated temperature up to 2000-2800 ℃ and precipitation of 350-500 mm as the basic climatic conditions for planting corn. However, the active accumulated temperature of ≥10 ℃ in the basin reached above 4500 ℃, and the precipitation during the growth of corn was 500-600 mm, indicating that the basin is rich in water and heat and is suitable for planting corn.
