Method for preparing bio-organic fertilizer from forest land tending residues

Abstract

A method for preparing a bio-organic fertilizer from woodland tending residues relates to the field of fertilizer preparation, and comprises the following steps: collecting fertilizer preparation raw materials including pruned branches of arbors such as pinus sylvestris, pinus koraiensis (different stocks), poplar and willow in woodland, and stumping branches of shrubs such as salix mongolica, rose willow, sea-buckthorn and caragana microphylla; crushing the fertilizer-making raw material to form a target fertilizer-making raw material; mixing the target fertilizer preparation raw material and the target excrement, adding the biological agent, and stirring to form a prefabricated mixture; and fermenting the pre-prepared mixture under the conditions of first temperature and first time to prepare the bio-organic fertilizer. According to the preparation method, local materials can be used, plant fertilizers such as pine twigs and animal fertilizers such as feces of various livestock are mixed for use, the raw material obtaining range is wide, and the method is small in pollution in the whole process, organic and environment-friendly, free of pollution and environmentally friendly. The fertilizer has the effects of resisting soil-borne diseases, promoting root growth and improving the fertilizer utilization rate, and is worthy of popularization and application.

Description

technical field [0001] The invention relates to the field of fertilizer preparation, in particular to a method for preparing bio-organic fertilizer from forest tending residues. Background technique [0002] The woodland configuration in the sandy area of ​​Yulin is mainly mixed trees and shrubs. The tree species include sylvestris sylvestris sylvestris, Korean pine (different stock), poplar, and willow. In order to adjust the stand density and accelerate the growth of trees, it is necessary Tending and thinning; shrub forests are distributed with red willow, salix, seabuckthorn and caragana, etc. Due to reasons such as unreasonable construction structure, lagging tending, extensive management, and aggravated drought in sandy areas, the diversity of shrubs and grasses in shrub shelter forests has decreased, and shrubs have grown and developed. Bad forest growth, short shrubs, and slow community succession lead to a decline in stand vitality and a weakened windbreak and sand-...

[0002] The woodland configuration in the sandy area of ​​Yulin is mainly mixed trees and shrubs. The tree species include sylvestris sylvestris sylvestris, Korean pine (different stock), poplar, and willow. In order to adjust the stand density and accelerate the growth of trees, it is necessary Tending and thinning; shrub forests are distributed with red willow, salix, seabuckthorn and caragana, etc. Due to reasons such as unreasonable construction structure, lagging tending, extensive management, and aggravated drought in sandy areas, the diversity of shrubs and grasses in shrub shelter forests has decreased, and shrubs have grown and developed. Bad, short shrubs and slow community succession lead to a decline in the vitality of the forest stand and a weakened windbreak and sand-fixing function

In order to improve the effectiveness of shelterbelt construction in the sandy area of ​​Yulin and promote the healthy growth of the forest land, the forest land needs to be tended and renewed. However, the value of the tending residues in the forest land is not fully utilized in the current technical measures. The fertilizer preparation method is to make full use of these residues to produce a bio-organic fertilizer, which is not only conducive to increasing production and income, but also conducive to fertilizing the soil, improving the soil micro-ecological system, reducing the amount of inorganic fertilizers, and improving the quality of agricultural products.
