Abstract

The invention relates to a growth-promoting complex microbial inoculant for dahurian larch, and a preparation method and an application method thereof, belonging to the technical field of microbial inoculants. In order to solve the problems of low natural renewal survival rate and poor effect of the dahurian larch, the invention provides the growth-promoting complex microbial inoculant for the dahurian larch. The growth-promoting complex microbial inoculant is prepared by compounding a chroogomphus rutilus microbial inoculant and a boletus edulis spore suspension according to a certain mass-volume ratio. When lateral roots grow from dahurian larch seedlings, the growth-promoting complex microbial inoculant is applied to soil and can form effective mycorrhiza with the root system of the dahurian larch, so the growth of the dahurian larch is promoted; the survival rate of the dahurian larch seedlings in barren and arid soil can be effectively improved; renewal is promoted; the quality ofnursery stocks and the yield of crops are improved; and the purposes of growth promotion, seedling strengthening, high yield and maintenance are achieved. The growth-promoting complex microbial inoculant for the dahurian larch provided by the invention is applied to promoting growth and renewal of the dahurian larch in places having suffered from fires and felling, and can promote material circulation and energy flow of an ecological system.

Description

technical field [0001] The invention belongs to the technical field of microbial bacterial agents, and in particular relates to a compound microbial agent for promoting growth of Xing'an larix and its preparation method and application method. Background technique [0002] The degradation of forest ecosystems has become a global problem. The overexploitation and use of forests by people and the impact of natural disasters such as fire have led to changes in the material cycle and energy flow process in the forest ecosystem, and the forest ecosystem cannot pass its own evolution. The replacement of forms has affected the self-recovery ability of natural ecosystems and disrupted the pace of human social and economic development. The Daxing'anling forest area is the main primitive forest area in my country, and it is also the largest forest area. It is an important timber supply base in my country and has an important impact on the regional climate and hydrological conditions. ...
