The integrative nutrient management can be conducted by accelcrating nutrient cycling through regulating stand structure and litter composition and by proper silvicultural manipulation. The improved varieties can be used by establishing recurrent cuttings orchards, and applying vegetative propagation of the following materials: seedlings of superior families; superior seedlings of good provenance and seed orchard; stump sprouts of elite trees in mature stand, improved clone of established seed orchards and second-generation elite trees in fast -growing period.展开更多
文摘Ecological stable, fast-growing and high-yield larch plantations can be established through intcgrative nutricnt management and utilization of improved varieties. The integrative nutrient management can be conducted by accelcrating nutrient cycling through regulating stand structure and litter composition and by proper silvicultural manipulation. The improved varieties can be used by establishing recurrent cuttings orchards, and applying vegetative propagation of the following materials: seedlings of superior families; superior seedlings of good provenance and seed orchard; stump sprouts of elite trees in mature stand, improved clone of established seed orchards and second-generation elite trees in fast -growing period.
