河西沿山冷凉灌区(以下称“本区”)是河西地区三个春小麦栽培生态区中占比重最大的一个区。随着当地农业生产条件的不断改善和科学施肥水平的不断提高,目前的一些春小麦主体品种已成为本区今后单产不断提高的重要限制因素之一。鉴于这种情况,张掖地区农科所于1980年从青海香日德农场引进了“高原338”春小麦品种,经1981——1983年的三年试种,每亩产量均在900斤以上,有些地块甚至达到每亩1250斤的水平。由此可见,“高原338”
Hexi Irrigation District (hereinafter referred to as “the district”) is the largest proportion of the three spring wheat cultivation ecotopes in Hexi area. With the continuous improvement of local agricultural production conditions and the continuous improvement of scientific fertilization levels, some main spring wheat varieties have become one of the important limiting factors for the continuous improvement of yields in the region in the future. In view of this situation, the Agricultural Science Institute of Zhangye Prefecture introduced “Plateau 338” spring wheat varieties from Xiangjide Farm in Qinghai Province in 1980. After three years of pilot plantations in 1981-1983, the output per mu reached more than 900 kg, and some The plot even reached the level of 1250 pounds per mu. Thus, “Plateau 338”
