晚香粳新品系SX0832是从软X射线辐射处理萌芽状态种子的后代中选出,具有香味、优质、高产、多抗的特点,生产与商品价值较高。为进一步发挥良种的特性,我们初步探索了与之相适应的三种栽培方法:香、普晚粳稻混播高产优质栽培:“V”字型(即二头促中间控)栽培;晚播及后季稻栽培。一、香、普晚粳稻混播高产优质栽培该品系的主要优点是味香、质优、高产,又具有抗稻瘟病等多抗特点,但茎秆较软弱,在重肥条件下,特别是在成熟灌浆后期(一般在抽穗40天之后),植株往往会倾斜,甚至倒伏,影响进一步高产和机械化收获。而目前市郊水稻生产上的当家品种,如秀水04,茎秆坚硬、产量高,米质却较差。为此,1988年我们与本所栽培室、市农业局技术推广站共 The new late Japonica line SX0832 is selected from the descendants of soft X-ray radiation germinating seeds and has the characteristics of aroma, high quality, high yield and multi-resistance, and has high production and commercial value. In order to further develop the characteristics of the elite, we tentatively explored the three cultivation methods suitable for it: Hong, Cape Late Japonica rice mixed high-yielding and high-quality cultivation: “V” shape Rice cultivation. First, fragrant, Cape Late Japonica rice mixed cultivation of high yield and quality cultivation The main advantages of this line is the flavor, high quality, high yield, but also has resistance to rice blast and other multi-resistance characteristics, but the stalk is weak, under heavy fertilizer conditions, especially in the mature Late filling (usually 40 days after heading), plants tend to tilt, or even lodging, affecting further high-yielding and mechanized harvesting. At present, the suburb of paddy rice production on the varieties, such as Xiushui 04, stalks hard, high yield, but poor quality of rice. To this end, in 1988 we and our cultivation room, City Bureau of Agriculture Technology Extension Station
