树木在幼年期是不能开花结实的,只有结束了幼年期达到性成熟阶段(即成年阶段)才能开花结实.在全面了解影响红松结实的遗传、起源、外界环境等主要因素的基础上,利用激素或激素类除草剂创造人工小环境,诱导促进红松造林苗提早结实取得了较好的试验效果.试验表明:结合优良造林苗木选择和配套造林技术,在红松新造林苗木成活后,于每年5月、7月上旬全株喷施特定浓度的赤霉素、ABT生根粉、乙烯利等植物激素能够促使红松实生苗提早结实,在实际操作中具有现实的有效性、操作性和实用性;红松S2-2优良苗木造林成活后,用2×10-4赤霉素全株喷雾处理,可使红松在第4年进入初果期.
Trees can not flowering and fructification in infancy, and they can flowering and fruiting only after the juvenile stage reaches the sexual maturity stage (mature stage) .Based on the comprehensive understanding of the major factors affecting the genetic, origin and external environment of the pines, Hormone or hormone herbicide to create artificial small environment and induce and promote the early fruiting of Korean pine plantation to get a better test result.The experiment shows that combining the good plantation seedling selection and afforestation technology, In May and July of each year, the whole plant was sprayed with gibberellin, ABT, ethephon and other plant hormones to promote early seedling growth of Pinus koraiensis seedlings. It is practical, practicable and practicable After the fine seedlings of Pinus koraiensis S2-2 were afforested, the whole plant was sprayed with 2 × 10-4 gibberellin, which allowed the korean pinewood to enter the early fruit stage in the 4th year.
