泾惠灌区(泾阳、三原、高陵)位于关中平原中部。地势平坦,灌溉历史悠久,有深厚的垆土层,保水、保肥性能好。小麦生育期间:大于或等于3℃的活动秘温1835.2℃,总日照时数1376.8小时,总降水量227.1毫米,是我省主要的小麦产地之一。该地区小麦亩产目前在500—800斤的基础上还能不能提高?潜力有多大?这是大家普遍关心的一个问题,我们仅从气象角度作些初步探讨。 Jing Hui irrigation area (Jingyang, Mihara, Gaoling) is located in the central Guanzhong Plain. Flat terrain, irrigation has a long history, deep soil layer, water, fertilizer and good performance. Wheat growth period: greater than or equal to 3 ℃ activity temperature 1835.2 ℃, the total hours of sunshine 1376.8 hours, the total rainfall of 227.1 mm, is the province of one of the major wheat origin. The current yield per mu of wheat in the area can not be increased on the basis of 500-800 kg. What is the potential? This is a problem that everyone is generally concerned about. We only make a preliminary study from the meteorological point of view.
