1986—1988年我们在广泛开展调查分析和综合论证的基础上,针对影响小麦生产的主要限制因子,进行了小麦低产变中产的综合技术研究与应用工作,开展了大规模地科技协作与攻关,获得了小麦连续两年大幅度增产的效果。1987年小麦收获面积39.85万亩,总产8.16万吨,比1986年7.08万吨增1.08万吨,增15.25%,平均亩产204.8公斤,比1986年增12.4公斤,增6.44%,首次跨入中产行列。1988年全市小麦39.76万亩,总产8.81万吨,又比1987年增产0.65万吨,增7.97%;平均亩产221.6公斤,比1987年增16.8公斤,增8.2%。同时涌现出小麦亩产达到250公斤以上的乡镇三个,面积6.26万亩,占全市面积15.74%;亩产300公斤以上单位一个,面积2.31万亩,占全市面积5.81%。小麦持续增产丰收,使历来作为粮食增产“搭头”的夏粮,已成为继续发展粮食生产的主要支柱。现将本市小麦低产变中产综合技术研究与应用成果报道如下,供有关同行参考。
From 1986 to 1988, on the basis of extensive investigation, analysis and comprehensive demonstration, we conducted comprehensive research and application of low-yielding wheat production based on the main limiting factors affecting wheat production and conducted large-scale scientific and technological cooperation and research. Obtained wheat for two consecutive years a substantial increase in output effect. In 1987, the area harvested by wheat was 398,500 mu, with a total output of 81,600 tons, an increase of 10,800 tons over that of 70,800 tons in 1986, an increase of 15.25%. The average yield per mu was 204.8 kg, up by 12.4 kg over 1986, up 6.44% for the first time Middle ranks. In 1988, the city’s 397,600 mu of wheat and its total output reached 88,100 tons, an increase of 6,600 tons or 7.97% over 1987; the average yield per mu was 221.6 kilograms, up by 16.8 kilograms or 8.2 percent over 1987. At the same time, there emerged three villages and towns with a yield of more than 250 kilograms of wheat, covering an area of 62,600 mu, accounting for 15.74% of the total area of the city; one unit of more than 300 kilos per mu, covering an area of 2.31 million mu, accounting for 5.81% of the city. The continued yield increase of wheat has made it a staple of continuing grain production that has always been used as a summer grain-growing cereal. The city now low-yielding wheat comprehensive technology research and application results reported below, for the relevant peer reference.
