摘 要：
生物膜化生物肥是目前国际上流行的一种生物肥,因不同的植物所需的微生物种类不同,在其应用到实际生产之前需进行相应的实验,为了更好地培育马尾松幼苗,本研究利用一种自制的生物膜化生物肥,将其应用到马尾松幼苗的培育上,以期检验其效果。实验结果表明,生物膜化生物肥的使用可以显著地增加马尾松幼苗的净光合速率,而显著地降低其胞间二氧化碳浓度,但显著降低光能和水分利用效率。生物膜化生物肥可以显著地增大Y(II)、ETR和Fv/Fm,而对qP和qN没有显著的影响。光合速率的增大导致马尾松幼苗的根、地上部分以及总生物量地显著增加。这些结果表明,本生物膜化生物肥能够应用到马尾松幼苗的培育。

摘 要：
Biofilmed biofertilizers(BFBF)are different from regular biofertilizers.Different plants symbiose with different microorganisms,therefore BFBF should be tested before they are used in agriculture and forestry.In the present study,a new BFBF was used in culture of Pinus massonicana seedlings.These results showed that the BFBF significantly increased net photosynthesis rate and decreased intercellular CO_2 concentration,and at the same time significantly reduced the use efficiency of water and light.The BFBF significantly increased Y(Ⅱ),ETR,and Fv/Fm,but showed no effect on qP and qN.Increase in net photosynthesis rate induced by the BFBF resulted in significant increase in root biomass,shoot biomass,and total biomass.
