泰山松对生长的土壤都有哪些要求?

  在泰山松街机捕鱼电玩苗木生长初期,充足的养分对其生长是极为有利的。苗圃中幼苗所需要的养分和施肥量可以预先估算出来,这些肥料可以保证苗木幼小时的迅速生长。

  不同树种对养分的需求量是不同的,应区别对待。通常分为以下三类:①绝大多数一年生幼苗需肥量较少。②一年生松树实生苗、需养分较多的阔叶树和多年生的针叶树需肥量一般。③多年生的落叶树需肥量较多。

  通常泰山松是适宜于湿润环境,对土壤要求较严格,而两针或三针束的松树就比较能耐干旱,在较薄的土壤上也能生长。如两针一束的油松,对陆性气候和大气干旱有较强的适应性。

  对土壤的要求:松树可以生长在各种不同的土壤上。因针叶灰分含量低,能忍耐贫瘠土壤,但以种在疏松肥沃土壤上的生产力高。湿润地区的松树大多适宜酸性土壤。而有些松树,如白皮松和油松,则能适应含钙量多和pH高的土壤。松树根系有菌根菌共生。主要为外生菌根的菌丝体形成鞘,包围着短的侧根,有利于根系对水分和养料的吸收。因而诱发菌根发育对有些松树造林的成败至关重要。大多数松树不能生长在盐渍土上,因而不能靠近海滨生长。但是有些松树如由日本引种到中国的黑松街机捕鱼电玩,具有较强的抗盐能力。
