小麦是我市第一大粮食作物,常年播种面积230万亩左右,年产量30多万吨,分别占粮田总面积和总产量的50%和40%,小麦生产的好坏,直接左右着全市粮食生产形势。长期以来,我们始终把良种推广作为促进小麦产量提高的突破口,积极探索,常抓不懈,收到了显著的成效。1993年全市小麦收获面积234.18万亩,新良种推广面积达到了213.17万亩,占91%。据历年区域试验资料及大田调查数据汇总分析,在同等条件下这些新良种平均较普通品种增产16.8%,亩净增产26.2公斤,共增产小麦5.16万吨。回顾我们多年来所做的工作,主要可概括为以下几个方面:
Wheat is the largest grain crop in our city. The perennial planting area is about 2.3 million mu and the annual output is more than 300,000 tons, accounting for 50% and 40% of the total grain output and total output, respectively. The quality of wheat is directly affected by the production The city’s food production situation. For a long time, we have always regarded the promotion of elite as a breakthrough point to promote the improvement of wheat yield. We have actively explored and persevered with remarkable achievements. In 1993, the city’s wheat harvest area of 2,341,800 mu, the promotion area of new varieties reached 21,317 mu, accounting for 91%. According to the data from the regional experiments and the field survey data over the years, these new varieties increased 16.8% more than ordinary varieties under the same conditions, with a net increase of 26.2 kg and a total increase of 51,600 tons of wheat. Looking back over what we have done over the years, we can mainly summarize the following aspects:
