喷洒增产灵、920药液金杂3号的父本晋辐57—1,属晚熟品种,在开原地区生育期140天,母本黑龙11A,生育期110天。为了调节亲本的花期相遇,去年我们在5月14日先播父本晋辐57—1,当长到7叶1心时,即6月15日播母本黑龙11A,但由于遇到干旱,黑龙11A至6月28日才出苗,较正常年份晚出苗7天左右。我们虽然采取提早铲趟,多铲多趟、偏施肥等方法,促进母本生长,仍不见效。据7月10日定点调查,父本平均为11叶1心,而母本只有2叶1心,母本较正常花期相遇要求少2片叶,即偏晚7～10天。
Spraying Zeng Ling, 920 liquid Jinza 3, the father of Jin spoke 57-1, is a late-maturing varieties, in the open area of 140 days of growth, black female parent 11A, growth period of 110 days. In order to adjust the flowering date of the parents, last year we sowed his father, Jin spoke at 57-1 last May. When he grew to 7 leaves and 1 heart, on June 15 he telegraphed female 11A, but due to drought, Black Dragon 11A until June 28 before emergence, compared with normal late emergence of about 7 days. Although we adopted early shoveling trips, multi-shoveling and more fertilizing methods to promote the growth of female parents, still not effective. According to the designated survey on July 10, the male parent averaged 11 leaves and 1 heart, while the female parent only had 2 leaves and 1 heart. The female parent required 2 leaves less than the normal flowering period, ie 7 to 10 days late.
