发展杂交水稻是提高粮食产量的一条重要途径。1987年我县试种2000余亩杂交早稻,证明比常规稻分蘖力强,穗大粒多,产量高。一般亩增稻谷80公斤,高至170公斤,低的也有50公斤,增产幅度为20～25％。今年在去年的基础上扩大到7万亩,并由我局组织农村干部在昌赣公路傍的醪桥乡竹陂塅建立集中连片种植的5000亩杂交早稻,进行示范。7月19日邀请了地、县有关领导和农技人员进行现场验收和评议,从中选择好、中、差三种类型田18块实地验收,96户作典型调查,估测竹陂塅4750亩,“早杂”平均亩产为496公斤;验收实产最高达672公斤,与去年相比,单产和总产分别增加93公斤和441750公斤,增幅28.7％。
Developing hybrid rice is an important way to increase grain yield. In 1987, we planted more than 2000 mu of hybrid early rice in our county, demonstrating that it has stronger tillering ability, bigger spike and more grain yield, and higher yield. General mu acres of rice by 80 kilograms, up to 170 kilograms, there are low 50 kilograms, increase rate of 20 to 25%. This year on the basis of last year expanded to 70000 acres, and I organized by the Bureau of rural cadres in the Chang-Gan Highway near the marsh bridge Township bamboo 陂 塅 establish a contiguous 5000 acres planted early hybrid rice for demonstration. July 19 invited prefectural and county leaders and agro-technical personnel on-site inspection and acceptance, from which to choose good, middle and poor three types of fields 18 field acceptance, 96 households for a typical survey, estimated bamboo 陂 塅 4750 acres , “Za Za” average yield of 496 kilograms; acceptance of up to 672 kilograms, compared with last year, yield and total output increased by 93 kilograms and 441,750 kilograms, an increase of 28.7%.
