Study on Mediums for Seedlings in Pot of Masson Pine and Chinese Fir

  • Received Date: 1995-06-06
  • Study on Mediums was conducted for two species, Masson pine and Chinese fir,in the past two years.There were 10 different formulations for the test.The dry weight of the 100-day seedling of Masson pine in the pot with Bamboo leaves as the medium is 93.2%,43.9%,25.0% over those growing in the yellow soil,the vermiculite,the rough powder from bark respectively.The same result was got for the Chinese fir,the increasing rate is 53.9% 104.0%,42.9% respectively.The medium made up from the pine leaves is the second one for the pot.The difference is obvious in statistics.According to the relative analysis,the unit weight and hole rate of the medium are the most important factors for the seedling.Both the total and effective content of phosphine is the second most important factor.The response to each factor is the same in both species,except having different demand for nutritive element.The phosphine is much more important for the Masson pine,while Chinese fir is sensetive to nitrogen.The mediums made up from Bamboo or pine leaves have suitable physical condition,which make seedling grow well and fungulizm earlier.

Abstract: Study on Mediums was conducted for two species, Masson pine and Chinese fir,in the past two years.There were 10 different formulations for the test.The dry weight of the 100-day seedling of Masson pine in the pot with Bamboo leaves as the medium is 93.2%,43.9%,25.0% over those growing in the yellow soil,the vermiculite,the rough powder from bark respectively.The same result was got for the Chinese fir,the increasing rate is 53.9% 104.0%,42.9% respectively.The medium made up from the pine leaves is the second one for the pot.The difference is obvious in statistics.According to the relative analysis,the unit weight and hole rate of the medium are the most important factors for the seedling.Both the total and effective content of phosphine is the second most important factor.The response to each factor is the same in both species,except having different demand for nutritive element.The phosphine is much more important for the Masson pine,while Chinese fir is sensetive to nitrogen.The mediums made up from Bamboo or pine leaves have suitable physical condition,which make seedling grow well and fungulizm earlier.
