摘 要: | 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.

Abstract: | The tree in the the period of infancy can not flower and fruit, the trees only enter mature stage, they can flower and fruit. On the basis of comprehensively understand fruiting genetics, origin, external environment and other main factors, the tests have better effects on accelerating seed setting earlier by using hormone. Combining seedling selection and suitable plantation technique, the certain concentration of gibberellin, ABT rooting powder and ethephon are sprinkled the whole tree in May and the first ten days of July every year after new seedlings survived, which can accelerate seed setting earlier of Pinus koraiensis, there are of great effectiveness and practicability in the actual operation. s survived, the whole tree is sprinkled with gibberellin the fourth year. After superior seedlings plantation of Pinus koraiensis S2 -2 2 × 10 -4 ,Pinus koraiensis can enter primary fruit stage at |
