美国黑核桃播种育苗试验

Experiment on Seedlings and Cultivation of American Black Walnut

通过从美国相似气候区引进黑核桃种子,在玛纳斯、伊犁开展育苗试验表明,黑核桃播种育苗,春播种子需层积90～120d;秋播种子省工省力,能够提高苗木生长量。并初步研究和总结出了一套适合新疆发展的黑核桃播种育苗的技术;可充分利用研究项目在南北疆建立的黑核桃种子园,采集种子,进行播种育苗,降低生产成本,提高苗木质量,为黑核桃在新疆的大面积推广应用创出一条行之有效的途径。

The seeds of black walnuts were introduced from America in 1984.The cultivation experiment is conducted for seeds of the black walnuts,which were cultivated in south and north of Xinjiang in 1991.Seedling cul-tivation was carried out in Manas and Ili of Xinjiang.The seeds sown in spring need stratification of 90～120 d.Growing seedling in autumn can save labour and raise seedling growth.The techniques of cultivation seedling suitable for developing in Xinjiang have been studied and mastered.The black walnut seeds gardens can be developed in south and north of Xinjiang,based on the experiment results.The American black walnuts will be greatly disseminated and applied with collecting seeds,conducting seedling and cultivation,cultivating seedling with high quality and reducing production cost.
