摘要
对柽柳抗盐、抗旱、耐淹及群落形成的生态生物学特性和利用研究表明,柽柳在黄河口地区早春萌发,秋末落叶,主要为灌木,极少发育为乔木;既可在潮间带形成纯灌丛,也可在潮上带和盐渍区构成灌草丛,又可在黄河入海口新淤地最早发育为原生植被。通过刈割平茬,可促进枝条发育,单株出条量比对照增加50～70％,放牧可食量提高30％,编织用条率增加80％;潮间带平茬后迂大海潮灌茬,死亡率可达40～60％。幼嫩枝叶主要可牧期在5～6月,编织用条期在9月底以后收割。
The ecologlacal and bioligical characteristics of its resistance against salt, drought,flood as well as the formation of community eventually shows that, in the mouth area of the Yellow liver, the Chinese tamarisks,sprouting in early spring and fading in late autumn, are largely shrubs,some being able to grow into small trees. The Chinese tamarisks may grow into pure shrubs in the area between tides, or form a grove of shrubs and grass in the area above tides or in saline soil, or grow into primary vegetation in the newly—silted area near the mouth of the Yellow River. Cutting promote the sprouting of the twigs,the amout of twigs of each plant going up 50%～70% to control, the edible amout for grazing going up 30%, the amount of twigs for weaving going up 80%. When flooded by big tides,the death rate of the stubbles in the area between tides will amount to 40%～60%. The grazing period of the young twigs and leaves of the Chinese tamarlsks is from May to June, while setting in the weaving twigs should be after the end of September.
