How to promote the Growth of Pinus sylvestris var. mongolica?

The seedlings of Pinus sylvestris var. mongolica, the annual seedlings exhibit the highest incidence rate, with a mortality rate of up to 50% upon disease incidence . Over-reliance on chemical pesticides has caused serious problems such as soil compaction, degradation of soil fertility, increased drug resistance of the pathogens and pests, destruction of soil’s micro-ecological environment, increased crop phytotoxicity, and weak seedling growth.

In comparison to the use of chemical pesticides, the application of beneficial microorganisms and microbial metabolites represents a novel environmental-friendly approach for plant management as the latter does not cause pollution, releasing of residues, and killing of natural enemies and also lowers the possibility of drug resistance in pathogens and pests. This approach is conducive to human and animal safety, environment protection, disease prevention and treatment, and production improvement.

Introduction of a variety of plant rhizosphere beneficial microorganisms for a synergistic effect produced by their interaction with the plants significantly improves the microbial community structure in the nursery soil, ameliorates the physical and chemical properties of the soil, promotes the plant growth, and enhances the disease and stress resistance in plants. Therefore, it is an effective approach to resolve the multiple problems encountered in nurseries these days.
