研究水稻的生态型,对育种和栽培是十分重要的。我们在1975年,对上海郊区后季稻主要当家品种和我组选育的品系,进行分期播种试验。试图了解这些品种对日照和温度的反应特性。参加试验的品种有双丰一号、加农15、加农485、加农482、沪选95、农红73、农虎6号及我组新选育的4个品系,即1404、514、农虎6号×513、京引66×沪选19等,共计11份材料。分1l期播种,自6月9日起,每隔7天播一期,直到8月18日为止。种子先浸种一天,以铺纸种稻法直播栽培,每份材料播36穴,未设重复。田间管理按一般方法进
Studying the ecological type of rice is very important for breeding and cultivation. In 1975, we carried out staged seeding experiments on the major varieties of post-season rice in Shanghai suburbs and the strains selected by our group. Trying to understand these varieties of response to sunlight and temperature characteristics. Participants in the trial were Shuangfeng No.1, Canong15, Canong485, Cannon482, Huntuan95, Honghong73, Nonghu6 and the newly selected four lines of our group, namely 1404,514 and Nonghu 6 No. × 513, Beijing cited 66 × Shanghai election 19, a total of 11 materials. Divided 1l seeding, since June 9, every seven days broadcast until August 18 so far. The seeds were soaked in the first day, and the seeds were planted with the rice method for direct seeding cultivation. Each material was sowed 36 points without repetition. Field management according to the general method
