摘要
为提高针叶树苗木质量，促进针叶树生长，对光肥在针叶树种育苗中的应用进行大量实验研究。结果表明：不同浓度光肥对不同针叶树种苗木苗高、地径生长有促进作用；对种子的萌发亦有一定的影响。光肥适用范围广，应用方法简单，成本低，在针叶树种育苗中可推广应用。
In order to improve the quality and the growth,we have engaged in experiment of photo-microfertilizer in coniferous tree seeding,The results show that the different photo-micro concentrations on thegrowth of coniferous tree had advancing role。It acts on seed germination。The method is simple and low cost。It can be widely applied in coniferous tree seeding
