水稻脉酫泡沫塑料育苗经1981年3亩小试和1982年612亩初试证明效果良好。秧苗质量适于机插,大田产量平干或高于其它育苗方式。1983年,除继续在吉林、辽宁、河北试验外,北京农业大学受科研协作组委托,在全国主要稻区布点中试,在北京、上海、广东、江苏、福建、云南、湖北等七省市二十多个点1,200亩地上进行农业试验,鉴定育苗泡沫的农用性能和其对不同地区的气候、品种、生产条件的适应性及经济效益,以确定这项技术的适应范围和推广前景。二月至五月,各地相继育苗栽插,试验的初步结果十分喜人。北京地区在海淀区东北旺农场,朝阳区洼里公社、十八里店公社,通县台湖公社和我校涿县农场共800余亩面积上试验。有塑料薄膜大棚、小棚、平铺和露地等多种育苗方式,涉
Rice veins foam plastic seedlings by 1981 3 acres of small test and 612 acres of 1982 first test proved effective. The quality of seedlings suitable for machine insertion, field output or higher than other breeding methods. In 1983, Beijing Agricultural University was entrusted by the scientific research cooperation group to continue the pilot projects in Jilin, Liaoning and Hebei provinces. The pilot projects were carried out in major rice paddies nationwide. In seven provinces and municipalities including Beijing, Shanghai, Guangdong, Jiangsu, Fujian, Yunnan and Hubei, Agricultural experiments were conducted on 1,200 acres of land at more than 20 sites to identify the agronomic performance of seedling raising foam and its adaptability and economic benefits to climates, varieties and production conditions in different regions so as to determine the scope and promotion prospect of this technology. From February to May, nursery plants have been planted around the country. The preliminary results of the trial are very gratifying. Beijing area in northeast Wang Haidian farms, Chaoyang District, Wali commune, Shibalidian communes, Tongxian Taiwan Lake commune and our school Juxian farm a total of more than 800 acres of area test. A plastic film greenhouse, shed, tiling and open field and other nursery methods, involving
