根据苏香粳1号的生长发育特性,通过几年的实践,要获得苏香粳1号550～660kg/667m~2的产量,必须在保证足穗的前提下,争大穗,稳定结实率和千粒重。具体指标为:有效穗23万～24万/667m~2,每穗总粒数100～105粒/667m~2,结实率和千粒重分别稳定在90%以上和27～28g。要保征以上产量指标的实现,具体栽培上应掌握 According to the growth and development characteristics of Suxiangjing 1, after several years of practice, to achieve the yield of 550 ~ 660kg / 667m ~ 2 in Suxiangjing 1, the big spike and stable seed setting rate And thousand grain weight. The specific indexes are as follows: the effective spike is 230,000 ~ 240,000 / 667m ~ 2, the total number of grains per spike is 100 ~ 105 grains / 667m ~ 2, the seed setting rate and thousand grain weight are respectively stable at above 90% and 27 ~ 28g. To insure the realization of the above yield indicators, the specific cultivation should be mastered
