现代育苗工作,在世界上由裸根苗向容器苗方向发展,而容器苗又由在裸露环境下培育向在能控制各种环境因素的温室中培育方向发展。1974年瑞典容器苗在造林中的比重已达40%,美国1975年容器苗占苗木总产量的5%,我国已在黑荆树,油茶,桉树,油橄榄等树种的育苗中采用。根据十五省市自治区油橄榄现场经验交流会的精神,以及我国对油橄榄发展的规划,种苗需要量很大,在繁殖技术上必须采取积极的办法,才能满足对种苗发展的需要。为了提高苗木的成活率和质量,赶超世界先进水平,温室容器育苗和常规育苗技术应列入同等重要地位。下面就介绍容器育苗的一种营养袋育苗。
Modern seedling development in the world by the naked root seedlings to the direction of container seedlings, container seedlings in turn nurture by nurturing to control environmental factors in a variety of greenhouse cultivation in the direction of development. In 1974, the proportion of container seedlings in the afforestation reached 40%. In 1975, the container seedlings accounted for 5% of the total seedlings in the United States. China has adopted the seedlings of black wattle, camellia, eucalyptus and olive trees. According to the spirit of the symposium on olive oil field experience in the fifteen provinces, autonomous regions and municipalities and the plan for the development of olive in our country, the demand for seedlings is very large. In the breeding technology, we must take a positive approach to meet the needs of seedling development. In order to improve the survival rate and quality of seedlings, catch up with the world advanced level, greenhouse container seedling raising and conventional breeding techniques should be included in the same important position. The following describes a container nursery nutrition bag nursery.
