Largescale ehosenia (Chosenia arbutifolia (Pall.) A. Sky.) belongs to rare and valuable species and is classified as the third-class of conservation in China. It is distributed mainly in the northeast of Asia. It grows on the wet sites along stream courses or river banks in northeast of China,the distributional regularity is as following:from the north to the south, its amount tends to reducing, in Daxingan mountain forestry region, Largescale chosenia, the closer to river banks, the denser its density is, and often forms pure forests or mosaic community with populus suaveolens; in Xiao Xingan mountain and Changbai mountain gradually it reduces in amount, and often grows in the willowy bush. According to the literatures it is difficult to propagate by cutting, the experiment of this propagation has been done since 1981, to direct at the characteristics. As it is difficult to take root, the base part of cuttings in the 10ppm NAA have been immersed by the authors for 24 hours, and then was replaced by water and go on immersing for 3—7 days, after struck root into water, before and after being transplanted to the flowerpots and nursery, they must be carefully watered, so that the root system can develop well and survival rate is high. Experimental result indicates that the cutting of stump plant, root sucker or epicormic branch can strike root and survive easily, in the same young branch,the medial part is easiest to take root, and that the soil humidity is a dominant factor to raise the survival rate of cutting.

钻天柳是属于珍稀而被列为我国国家三级保护树种。它主要分布于亚洲东北部。在我国东北,沿河岸生于潮湿地区,似有如下分布规律:自北至南,数量有减少的趋势,在大兴安岭林区,愈近河岸,其密度愈大,常组成纯林或与甜杨组成镶嵌群落。在小兴安岭和长白山,数量渐减少,常生于柳丛间,据文献记载,本种扦插繁殖较困难,作者采用10ppm萘乙酸浸泡插穗基部24小时,然后换水继续浸泡3—7天,生根后,先后移载于花盆和苗圃,注意浇水,效果较好,成活率高,根系发育良好。试验结果表明,采自萌条,根出条或嫩枝的插穗,易于生根在活,同一嫩枝,中部者生根能力最佳,提高圃地插穗的成活率,土壤湿度是个主导因素。

The sprout regeneration of Chinese fir (Cunninghamia lanceolate) is suitable to a short rotation. But there are arguments about its advantages and disadvantages in practice. The growth, stem fullness, rate of curve at butt, distribution and weight of root system, cost were compared between the seedling stand and the sprout stand. It is concluded that the sprout stand is not worse than the seedling stand in growth and stem while the investment in the sprout stand is only 1/3 as much as that in the seedling stand....

The sprout regeneration of Chinese fir (Cunninghamia lanceolate) is suitable to a short rotation. But there are arguments about its advantages and disadvantages in practice. The growth, stem fullness, rate of curve at butt, distribution and weight of root system, cost were compared between the seedling stand and the sprout stand. It is concluded that the sprout stand is not worse than the seedling stand in growth and stem while the investment in the sprout stand is only 1/3 as much as that in the seedling stand. The effect of different numbers of stump plant which remains on high growth has been studied. The optimun number of stump plant is 2.

杉木萌芽更新适于短轮伐作业,在实践中对其利弊尚存在争议。本文根据在苏南丘陵地区的长期试验,对萌芽林与实生林的生长、树干圆满度、树干基部弯曲率、根系分布与重量和更新费用作了分析比较,得出萌芽林无论在生长和干形上均不比实生林逊色,而投资却仅占实生林1/3,具有投资少,更新可靠,经济效益好的特点。文内还比较了伐桩萌条存留株数对高生长的影响,在去萌定株时以保留两株萌条者高生长最佳。

Micropropagation of Prunus donarium var. spontanea was conducted. After two steps sterilizing with 0.1% concentration of HgCl 2, stem segment from stump plant was served as explant to induce shoot formating. The media for subculture were supplemented with high or low concentrations of cytokinin alternately so as to inhibit glass plantlet formation. Survival rate of plantlet could reach 90% after transplanting to soil and 150,000 seedlings could be manufactured per year.

阐述了日本叶用经济植物大岛樱的工厂化育苗技术。以萌枝茎段为材料,采用HgCl22次消毒外植体;不经愈伤组织诱导丛生芽;通过壮芽培养,在短时间内提供大量适宜生根的壮苗;采用含高、低浓度细胞分裂素的培养基交替继代培养,减少玻璃苗的产生;瓶苗移栽一步成苗的地苗栽培技术,成苗率达90%。年产苗15万株,为大岛樱生产提供最优良的育苗技术
