Problems solved by technology

At the same time, with the increase of nitrogen, phosphorus and potassium macronutrient fertilizer application, and with the growth of forest trees, the medium and trace elements in the soil are often not replenished in time, which seriously affects the full play of the macronutrients and the yield of Masson pine. Further improvement, so it is necessary to add medium and trace elements

Abstract

The invention discloses composite microbial granules for promoting growth of Pinus massoniana as well as preparation and application methods thereof. The composite microbial granules are prepared by enveloping solid culture of ectomycorrhizal fungi containing one or more of Suillus bovinus (Pers.) Roussel and Pisolithus tinctorius (Pers.) Coker and Couch as a mycorrhizal fungi, phosphate-solubilizing bacteria (Pseudomonas fulva)yL14 with preservation number of CCTCC M 2011356 and potassium bacteria with an enveloping material, adding nitrogenous fertilizer, phosphate fertilizer, potassium fertilizer, middle microelement and soil improvement agent, and mixing and granulating. By adopting the composite microbial granules disclosed by the invention, the absorption of nutrient elements by the Pinus massoniana root system is promoted, the utilization efficiency of the nutrient elements is improved, and the growth of Pinus massoniana is promoted; the water and fertilizer retention capabilityof the soil is enhanced, soil nutrients are supplemented, and microecology of the soil is improved; and the composite microbial granules have important significance in preventing and controlling landcapability decline of the soil, are convenient in material sources, low in cost and good in fertilizer efficiency, and are beneficial to popularization and application.

Description

technical field [0001] The invention relates to a composite microbial granule for promoting the growth of masson pine and its preparation and application method. Background technique [0002] Masson pine (Pinus massoniana) is the main fast-growing timber tree species in southern my country, and it is also an important raw material for papermaking. Drought-resistant and barren, it is a pioneer tree species for afforestation in barren mountains and wastelands in acidic soil. It is produced in the south of Qinling and Huaihe River basins, from coastal low mountains and hills in the east, to the east slope of Daxiangling in western Sichuan in the west, to southern China in the south, and a small amount in Taiwan. It has high economic value and wide application. Its wood is used for construction, furniture and water engineering. The roots can be used to cultivate Poria cocos. The trunk can be used for cutting pine resin. The bark can be used to make adhesives and wood-based panel...
