Reduction phyllostachys praecox forest fertilization method

Abstract

The invention discloses a reduction phyllostachys praecox forest fertilization method, and belongs to the technical field of plant nutrition management. The method is characterized by comprising the following steps that 1), a phyllostachys praecox forest high-yield stand structure is constructed, the density of standing bamboos is 15000-18000 plants / hm<2>, the diameter at breast height of the standing bamboos is 3-5 cm, and the number ratio of one-year-old standing bamboos to two-year-old standing bamboos to three-year-old standing bamboos is 4: 4: 2; 2), plant hole fertilizing is carried out, fan-ring-shaped grooves are formed at the position, being outward by 10 cm, of base parts of two-year-old phyllostachys praecox, and compound fertilizer is applied; and 3), after fertilizer is evenly applied, soil covering and compaction are carried out. According to the method, the use amount of the fertilizer can be reduced by 30-40%, the utilization rate of the fertilizer is increased to 50% from about 35%, and the quality of the bamboo shoots is improved.

Description

technical field [0001] The invention belongs to the technical field of plant nutrition management, and in particular relates to a fertilization method for reducing the amount of thunder bamboo forest. Background technique [0002] Bamboo is a typical clonal plant, which has a strong role in sharing resources, energy and information among ramets in a heterogeneous environment. In the process of high-efficiency cultivation of bamboo shoot forests, due to the large amount of biomass output (bamboo shoots, bamboo wood) every year, fertilization is an important management measure, which can timely supplement the elimination of a large amount of nutrients in the forest land soil. At present, the traditional fertilization methods for Phyllostachys praecox forests are sprinkler method and furrow method (fertilization in shallow furrows with a depth of 10-15 cm and a width of 10 cm every 3 m or so), and the fertilizer utilization rate is low or the labor cost of fertilization is high...

Problems solved by technology

At present, the traditional fertilization methods for Phyllostachys praecox forests are sprinkler method and furrow method (fertilization in shallow furrows with a depth of 10-15 cm and a width of 10 cm every 3 m or so), and the fertilizer utilization rate is low or the labor cost of fertilization is high

Due to long-term excessive fertilization, not only the productivity of the Phyllostachys praecox forest site has declined, the yield and quality of bamboo shoots have declined significantly, but it has also caused serious pollution to the surrounding environment, especially the eutrophication of the water near the Phyllostachys praecox forest.
