在华主席的亲切关怀下,杂交水稻得到了大面积推广应用。为了探讨杂交水稻“南优二号”的适宜播种期、移栽期和秧龄,我们于1976年进行了分期播种、移栽试验。播种期:自6月15日到6月30日,每5天播一期,采用水育大秧。每亩秧田播种量40斤。移栽期:从7月15日到8月5日,每7天栽一期,同一栽期移栽4个播期的秧苗,共15个小区,(因秧苗不足,缺6月20日播,8月5日栽的小区)。移栽后的管理与一般大田相同,现根据试验结果小结如下。
Under the gracious care of Chairman Hua, hybrid rice has been widely popularized and applied. In order to investigate the appropriate sowing date, transplanting date and seedling age of hybrid rice “Nanyou No.2”, we carried out staged sowing and transplanting experiments in 1976. Sowing period: From June 15 to June 30, every 5 days broadcast a period, the use of aquaculture Dayang. Seedling per acre sowing 40 kg. Transplanting period: from July 15 to August 5, planted every 7 days, the same planting transplanting 4 sowing seedlings, a total of 15 plots (due to lack of seedlings, the lack of broadcast on June 20 , Planted on August 5 district). The management after transplanting is the same as that in general field, and the summary is based on the test results as follows.
