淮北是我国商品粮基地之一,而小麦则是淮北地区主要的粮食作物,如何保持小麦的稳产、高产,实为搞好商品粮基地的重要关键.从小麦历年的平均产量来看,以宿县地区为例,在五十、六十年代,较好的年份,平均亩产在80～100斤左右.到七十年代,平均亩产比五、六十年代有显著的提高.从1970年的111斤提高到1979年的274斤.其中,一般年份的平均亩产,在140～200斤之间,产量都是较低的.据我们调查分析,七十年代小麦增产的原因,主要有两方面:一方面是农业技术水平有所提高,如采用新的优良品种,加强小麦田间管理以及水利工程在抗
Huaibei is one of the commodity grain bases in our country, and wheat is the main food crop in Huaibei area.How to keep the stable and high yield of wheat is the key to improve the commodity grain base.According to the average output of wheat over the years, For example, in the fifties and sixties, and in the better years, the average yield per mu is between 80 and 100 kilos. By the 1970s, the average yield per mu was significantly higher than in the 1950s and 1960s. From 1970’s Kg to 274 kg in 1979. Among them, the average yield per mu in the general year is between 140 and 200 kg, and the production is relatively low. According to our survey and analysis, the main reasons for the increase in wheat production in the 1970s are twofold : On the one hand is the improvement of agricultural technology, such as the use of new fine varieties, strengthen wheat field management and water conservancy projects in anti-
