摘　　要：对红王子锦带生物学特性及苗期高生长节律进行观察和研究,结果表明:哈尔滨地区栽植的红王子锦带一般在4月中旬叶芽开始膨大,4月下旬芽开放4,月末开始展叶;5月初为展叶盛期,5月中下旬现蕾;6月上旬初花,6月中、下旬进入盛花期。扦插苗观察6年,高生长于第2年进入速生期,随着树龄增长高生长逐渐趋于缓慢;高生长一年中有2个高峰,二次生长高峰大于一次生长高峰,并于9月中旬停止生长,温热不足,冬眠前生理成熟受限。Observation of biological characteristics ＆ seedling growth rhythm of Weigela florida were studied. Result shows that： buds of Weigelaflorida planted in Harbin region generally begin to expand in the middle of April;buds open in late April, and begin to expand leaves at the end of April;leafing stage is in early May;flower bud is in late May;initial flowering is in early June, and full-bloom stage is in middle ＆ late June. Cuttings were observed for 6 years;the height growth enter the fast-growing period in the second year;height growth tends to be slow along with the age growth;height growth have two peaks in a year; second growth peak is greater than the first peak of growth, and stop growing in the middle of September; physiological maturity is restricted before hibernation due to lack of warm.
