近几年来,我们遵循“积极引种、认真试验、慎重示范推广”的原则,在稻麦油瓜品种筛选、繁育、推广中,取得了一些成绩。5年来共引进稻麦油瓜品种(系)209个,经试验示范,已在全县推广应用的品种有11个,累计推广稻麦良种404.6万亩,油菜良种62.5万亩,西瓜良种14.5万亩。1989年推广的良种,分别占水稻总面积的96.2％,小麦总面积的95.6％,油菜总面积的91.5％和西瓜总面积的95％以上。加上其他增产措施,在吴县取得了显著的增产效益。平均每亩水稻增产51.68kg,每亩小麦增产26.8kg,充分显示了良种的增产作用。在推
In recent years, we have followed the principle of “actively introducing, earnestly experimenting, demonstrating and promoting prudently”, and achieved some successes in the screening, breeding and popularizing of rice, rape and melon varieties. In the past five years, a total of 209 varieties of rice, rapeseed and melon have been introduced, 11 of which have been popularized and applied in the whole county by testing and demonstrating. There have been a total of 4,406,000 mu of rice and wheat varieties, 625,000 mu of rapeseed varieties and 145,000 varieties of watermelon seeds mu. The improved varieties promoted in 1989 accounted for 96.2% of the total rice area, 95.6% of the total area of wheat, 91.5% of the total area of rapeseed and 95% of the total area of watermelon, respectively. Coupled with other measures to increase production in Wu County has made significant gains in production. The average yield per mu of rice 51.68kg, yield 26.8kg per mu of wheat, fully shows the yield of improved varieties. Pushing
