在全国小麦区划中,河西属北方春小麦区。七十年代以来,春小麦播种面积约占粮食作物播积面积的60—70%,总产量占粮食作物总产量的60%左右,有的县高达70%,是河西的主要粮食作物。春小麦生长发育受热量条件的影响很大。研究它们之间的关系,并根据这些关系,采取适当的农业技术措施,能够促使春小麦生长发育生长,从而获得较高的产量。一、适宜播种期的温度根据武威农气站1973—1975年和武威县中坝公社农科站1976、1978年所进行的春小麦分期播种试验产量资料(见表1),1973年3月11日和16日、1974年3月31日、1975年3月11
In the national wheat division, Hexi is a northern spring wheat area. Since seventies, the sown area of spring wheat accounts for about 60-70% of the sown area of food crops, and the total output accounts for about 60% of the total output of food crops. In some counties, up to 70% is the main food crop in Hexi. Spring wheat growth and development by the heat conditions are greatly affected. Studying the relationship between them, and according to these relations, adopting suitable agricultural technology measures can promote the growth and development of spring wheat and obtain higher yield. First, the appropriate sowing temperature According to the Wuwei Farm Station 1973-1975 and Wuwei County Zhongba Agricultural Station 1976, 1978 conducted by the spring wheat sown trial yield data (see Table 1), March 11, 1973 And 16, March 31, 1974, March 11, 1975
