Technology of Breeding Seedlings of Betula Luminifera in Light Media Container

[Objective] Study the technology of breeding seedlings of Betula luminifera in light media container.[Method] B.luminifera nonwovens light matrix container breeding by orthogonal design was to research sprouts transplanting time,the proportion of matrix,slow-release fertilizer intake and other factors affect optical quality seedlings of B.luminifera.[Result]Different sprouts transplanting time,different formulation of the matrix,the slow-release fertilizer have significant influence on growth of the B.luminifera matrix container seedlings.[Conclusion]Transplanting in march,peat∶perlite∶ rice chaff= 6∶2∶2,adding 2 kg/m3 APEX18-6-12 combination of slow-release fertilizer,will make production costs low,seedlings quality better.
