Geographical problems What kind of growing conditions does wheat like?

Spring wheat likes cold climate, is relatively cold-resistant, adaptable and widely distributed, with an average daily temperature of about 0℃; That is to say, "Dingling" can be sown, it can germinate and emerge when planted at 4-5℃, and it can tolerate low temperature around -6℃ at seedling stage. Due to the different varieties of early, middle and late maturity, the whole growth period should be ≥ 0℃ and the accumulated temperature should be between 1600-2 100℃. The growth period is 85 days-105 days. The ethnic areas in the north, northwest and southwest can meet the growth conditions of spring wheat. Mainly distributed in Inner Mongolia, Ningxia, Linxia, Gansu, Gannan Autonomous Prefecture, Hexi Corridor, Xinjiang, Qinghai, Tibet and other places, from the valley slope above 2500 meters above sea level to the lakeside plain around 4500 meters, from humid and semi-humid areas to semi-arid and arid areas. Great progress has been made in planting spring wheat in ethnic areas, and a number of improved spring wheat varieties with strong resistance, wide adaptability and high yield have been cultivated and popularized in various places. For example, spring wheat in Chayouzhongqi, Zhuozi and Guyang counties located in Yinshan hills of Inner Mongolia has exceeded 1000 kg, and Nuomuhong Farm in Qaidam Basin of Qinghai Province has set a world record of 1.585 kg per mu. With the popularization of agricultural science and technology, in recent years, spring wheat has reached the highest yield per mu.

winter wheat

Ethnic minority areas mainly include Guangxi, Guizhou, Yunnan, Tibet and other regions (provinces). Most of these areas (provinces) are mainly rice, and winter wheat is planted as winter crops in dry land. Although the planting area is small, its planting is helpful to improve the multiple cropping index and increase the total grain output. Because the people in these areas are mainly rice, the commodity rate of wheat is high. The planting area of winter wheat reached a new high, with an altitude of 465438+. In the plateau area of 3000-3800 meters, high yield can be obtained and rust is not easy to occur. /kloc-0 bred an excellent variety of "fat wheat" in 1959./kloc-0 began to be popularized in a large area in 1972, and soon became the second largest cultivated crop in Tibet, surpassing spring wheat and second only to highland barley. It has the characteristics of strong tillering ability, high effective tillering rate, good stress resistance, tough stem and lodging resistance. Pengbo Farm in Lhasa 1 1.6 mu experimental field, with yield per mu 1339 kg.
