  泰山松基地为大家介绍泰山松起苗时切忌不要手拔:

  泰山松苗木基地三种保湿方法。绑裹草绳法,用草绳或稻草将树干包好,再用细草绳固定在树干上。将草绳喷湿,接着用塑料布包裹草绳的外面,最后把塑料布捆在树干上。靠近树体下部的土球处把塑料布展开,将基部覆土浇透水后,连同干兜一并覆盖地膜。地膜周边用土压好,利用土壤温度调节作用,保证被包裹树干的空间内有足够的温度和湿度,不用再浇水。

  在泰山松苗木生长初期,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。
