一、工作的回顾和进展我省自1956年以来,双季稻面积由无到有地逐年扩大,到现在已达1,700万亩左右。回顾一下历史,当时原有的晚籼地方老品种“黄毛粘”等,因不耐寒,易倒伏,易落粒,产量低,自然很快地受到淘汰。而选育新的品种一时又难于跟上,于是才从杭嘉湖地区引进了比较耐瘠的以“10509”为主的一季晚粳品种,用稀抪长秧令办法作双晚种植,这对发展双季稻起到了积极作用。到了六十年代初期,又引进了农垦58。该品种适应性广、耐肥、高产,随着生产水平的不断提高,种植面积迅速扩大,成为我省的主要二
I. Review and Progress of Work Since 1956, the area of double-crop rice in our province has been expanding year by year from scratch, reaching 1,700 mu now. Recalling the history, when the original late indica local old varieties such as “yellow hair sticky” and so on, because of not cold, lodging, easy to fall, the output is low, naturally quickly be eliminated. However, it is difficult to keep up with the new breed for a while. Therefore, it is necessary to introduce a more late-season japonica rice variety “10509” mainly from Hangjiahu region, Double crop rice has played a positive role. By the early 1960s, Nongken 58 was also introduced. The varieties of wide adaptability, resistance to fat, high yield, with the continuous improvement of production levels, planting area expanded rapidly, as the main two in our province
