中籼扬稻4号具有高产稳产、抗病抗虫等特点。1988年我们试种20余亩,平均亩产686.8千克。1989年扩大示范种植到1000多亩,平均亩产606.3千克,其中109亩平均亩产达652.4千克;夏联村农户王德勤在麦茬田种植的1.3亩,实收亩产达693千克。我乡经几年来试验示范种植,初步摸索到扬稻4号亩产650千克的高产栽培技术。 Indica rice Yangdao 4 with high and stable yield, disease and insect resistance and other characteristics. In 1988 we experimented more than 20 acres, an average yield of 686.8 kilograms. In 1989, the demonstration planting was expanded to more than 1,000 mu with an average yield of 606.3 kg per mu, of which 109 mu averaged 652.4 kg per mu. Wang Delin, a farmer in Xialian Village, planted 1.3 mu of wheat stubble fields and collected 693 kg of mu per mu. After several years of experiment and demonstration planting in our country, we initially found a high-yielding cultivation technique of 650 kg per mu in Yangdao 4.
