宝鸡市旱地、半旱地面积很大。其中原区早地、半旱地共311.69万亩,占全市总耕地面积的44.1％;山区坡旱地260.86万亩,占36.9％。这类地区小麦历年面积约310万亩,占全市小麦面积390万亩的79.5％。是小麦集中产区。目前这类地区粮食产量水平较低,1971—1980年粮食平均亩产凤翔县为268斤,麟游仅133斤。因此,研究和解决我市旱地小麦产量低而不稳,对搞好我市的商品粮基地建设有重要意义。一、有机无机相结合培肥地力本市年降雨量虽在650毫米左右,但50—
Baoji City, dry land, semi-dry land area. Among them, there are a total of 3.1169 million mu of early and semi-arid land in the former district, accounting for 44.1% of the total cultivated land in the city; and 2.6086 million mu of dry land in mountainous slope, accounting for 36.9%. This area of wheat over the years the area of about 3100000 acres, accounting for 79.5% of the city39000000 acres of wheat area. Wheat is a concentrated area. At present, the grain output in such areas is relatively low. The average grain yield per mu in 1971-1980 was 268 kg in Fengxiang County and only 133 kg in Linyou. Therefore, it is of great significance to study and solve the problem of low and unstable wheat yield in dry land in our city and to improve the construction of commercial grain base in our city. First, the combination of organic and inorganic Fertility Fertility Although the city’s annual rainfall of about 650 mm, but the 50-
