石榴在我国已有悠久的栽培历史。果实营养丰富,美味可口,深受群众欢迎。果皮、根、叶、花等均可入药,有广乏的医疗用途。广大群众有在庭院栽植石榴的习惯。由于其主、侧根发达,易生萌蘖根,耐旱、耐贫瘠,枝叶牛羊不啃等特点。近些年来被用于山区干旱阳坡造林,成为很有发展前途的水土保持经济林树种。但大面积造林存在的问题是扦插育苗成活率低,一般仅30—40％左右。因此,我们结合生产做了石榴扦插育苗试验,初步找到了影响扦插育苗成活的因素,现介绍如下:
Pomegranate in our country has a long history of cultivation. Fruit nutritious, delicious, welcomed by the masses. Peel, roots, leaves, flowers, etc. can be used as medicine, there is a lack of medical use. The masses have the habit of planting pomegranates in the courtyard. Because of its main, lateral roots developed, easy to sprout millets, drought tolerance, tolerance barren, foliage, such as cattle and sheep do not chew and so on. In recent years, it has been used for afforestation in mountainous and dry sunny slopes, and has become a very promising species of water and soil conservation economic forest. However, the problem of large-scale afforestation is that the survival rate of cuttage seedlings is low, generally only about 30-40%. Therefore, we combined with the production of pomegranate cutting seedling test done, initially found the factors that affect the survival of cutting seedlings are introduced as follows:
