本试验对西南桦网袋容器育苗基质进行了研究,试验中设计6个配方,并以生土为对照基质,在苗高为1cm、2cm和3cm时分别移苗到新型基质中去,移苗后2个月进行苗高、地径和成活率调查表明:配方1(发酵杉木削:草煤:烟囱灰:珍珠岩=2:5:2:1)的基质中,西南桦苗高、地径最为突出;成活率最高为配方1和配方2,都达到94.23%,其移苗期在2cm的时候成活率最高。
In this experiment, six kinds of recipes were designed in this paper. In the experiment, six recipes were designed and the soil was taken as the control substrate. The seedlings were transplanted to the new substrate at seedling height of 1cm, 2cm and 3cm respectively. The investigation of seedling height, diameter and survival rate in the last two months showed that in the matrix of formula 1 (fermented Chinese fir cuttings: straw: chimney ash: perlite = 2: 5: 2: 1) The most prominent diameter; the highest survival rate for the formula 1 and formula 2, both reached 94.23%, the survival rate of 2cm in the seedling stage when the highest.
