通过对马尾松苗木的菌根土接种及苗圃地选择的试验,可知培育马尾松菌根化苗木,应选择土壤中菌根菌含量丰富的马尾松疏残林地、近年采伐迹地、林中空地、林缘下方,以及前茬是马尾松或湿地松的老苗圃地作为马尾松苗圃地。在这些地类上,结合施以足量腐熟有机肥做基肥,培育的马尾松苗木菌根感染率一般都在85%以上,苗木质量好。上述地类外的新垦苗圃地,应在生长健壮,无病原菌,而且最好是生长有马勃子实体的马尾松林下,挖取0—20厘米表土层进行菌根土接种,培育的松苗也可获得较高的菌根感染率。历史上未种过松类、栎类,附近又无松林的荒山荒地,用作马尾松苗圃地,苗木的菌根感染率极低,质量差。
Through the test of mycorrhizal inoculation and selection of nursery in Pinus massoniana seedlings, we can know that Masson pine mycorrhizal seedling should be selected to cultivate massoniana mycorrhizal seedlings. In recent years, Below the edge of the forest, and the former crop is an old nursery of Pinus massoniana or Pinus elliottii as a Masson pine nursery. In these types of land, combined with sufficient amount of decomposing organic fertilizer as a base fertilizer, cultivating Pinus massoniana seedling infection rates are generally above 85%, good seedling quality. The above-mentioned land reclamation nursery land, should grow robust, non-pathogenic bacteria, but also is the growth of Macphersonorum fruiting bodies, dig 0-20 cm topsoil for mycorrhizal inoculation, cultivating pine seedlings Can also get a higher mycorrhizal infection rate. The history has not been planted pine, oaks, pine forests and no adjacent barren wasteland, used as Masson pine nursery, seedling mycorrhizal infection rate is very low, poor quality.
