俄罗斯大果沙棘栽培价值及实生苗育苗技术

Cultivation Values and growth seedlings technique of Russian Hippophae rhamnoides L.

阐述了沙棘的生态价值,食用、药用价值和饲用价值及其开发应用前景,同时对引进的俄罗斯大果沙棘实生苗育苗技术进行研究.沙棘种子与幼苗均具有较高的抗低温能力,早播比晚播成苗率高,低床比高床、垄作抗旱保苗;机械喷灌效果好,苗木根系发达,生长势强.施肥以有机肥和无机肥混合作基肥,追肥1～2次,叶喷微量元素均能促进幼苗生长.

The values of ecology,edible,medicine and feed and the developement prospect of Hippophae rhamnoides L.were summarized.Besides,the growth seedling technique of introduced variety was studied.The lowtemperatureresistance ability was high in seeds and seedlings.The seedling rate in early sowing was higher than in the last one.The droughtresistance and seedling ability of low bed seedlings were higher than high bed ones in ridge culture.The effect of mechanical sprinkling irrigation was good.So the root system of seedling was welldeveloped and the growth power was strong.The fertilizer measures,mixture between mature and mineral fertilizer was base fertilizer,1～2 times topdressing and the trial fertilizer was sprayed in the leaf,could promote seedling growth.
