沈阳市四个郊区两个县1986年水稻总面积已达180万亩以上。从日本引进的常规粳稻品种如秋光、丰锦等,近年亩产一般是400～500公斤。我国自己通过籼粳稻杂交等育成的株形好的常规粳稻品种以及杂交粳稻组合的一般产量是500～600公斤。自1983年以来,沈阳地区已改变了从来以日本品种为主的局面。但就食味来说,日本品种还是较好的。感染稻曲病也较轻。所以,暂时还可能保持一定的面积。这里所谓超高产,是指沈阳地区在大面积上有无可能每亩再增产100公斤,即每亩单产
Shenyang City, two suburbs in four suburbs in 1986 the total area of rice has reached 180 million mu or more. Conventional japonica rice varieties introduced from Japan such as Qiuguang, Fengjin, etc. In recent years, the average yield per mu is generally 400 to 500 kilograms. The average yield of conventional japonica rice varieties and japonica hybrid rice cultivars that are cultivated in China by crossing indica and japonica hybrids is 500-600 kg. Since 1983, the Shenyang area has changed its status as a Japanese variety. But for taste, the Japanese breed is better. Infected smut is also lighter. So, for the time being may also maintain a certain area. The so-called super-high yield here refers to the Shenyang area in a large area is it possible to increase production of 100 kg per mu, that is, per mu yield
