Embodiment Construction

[0012] The present invention will be further described below:

[0013] The present invention achieves the above object through the following technical solutions: by adding compound fertilizers containing nitrogen, phosphorus and potassium, the fertilizer effect of the produced compound fertilizer is guaranteed to be balanced; the use of biological carbon delays the release process of fertilizer nutrients in the soil to solve the problem of lasting fertilizer effect Problem: use the porous structure of biochar to provide a good habitat for soil microorganisms; use the characteristics of large specific surface area of ​​biochar to adsorb and retain heavy metals in soil, thereby reducing the harm of heavy metals to plants.

[0014] The preparation method of the present invention comprises the following steps:

[0015] (1) Raw material collection: collect the landscaping waste such as branches, leaves, grass clippings and fallen leaves with a diameter of less than 1cm produced dur...

Abstract

The invention discloses a method of utilizing greening waste to produce high-efficiency compound fertilizer. Aiming at the problem that simplex landscaping waste is unbalanced in nutrient, the compound fertilizer is doped with nitrogen, phosphorus and potassium, so that fertilizer effect balance is ensured; aiming at the characteristic that chemical fertilizer is too fast while not lasting in fertilizer effect, fermented green waste is added as organic fertilizer, charcoal is added and can delay release of fertilizer nutrients in soil and lower leaching of the fertilizer nutrients, and porousstructure of the charcoal becomes a good environment for soil microorganisms to inhabit, so that soil beneficial microorganisms are protected while multiplication thereof is promoted. Finally, aimingat the problem that soil heavy metal pollution is serious, the charcoal is added into the compound fertilizer, and the characteristic that the charcoal has the porous structure, large specific surfacearea and negative charge on the surface is utilized, so that soil heavy metal can be adsorbed and retained greatly, and damage to plants caused by the fact that the soil heavy metal enters bodies ofthe plants is reduced.

Description

technical field [0001] The invention relates to a production method and fermentation engineering technology, in particular to a production method of an organic-inorganic high-efficiency compound fertilizer produced by adding chemical fertilizer and biochar to fermented landscaping waste compost. Background technique [0002] In the prior art, there are reports of making organic fertilizer or bio-organic fertilizer by fermenting crop stalks or green wastes. However, due to the unbalanced nutrition of the green waste itself, the organic fertilizer or bio-organic fertilizer made from the fermented product has an unbalanced fertilizer effect, and the fertilizer effect of the compound fertilizer is not long-lasting, which cannot effectively reduce the harm of heavy metals to crops and promote the reproduction of beneficial microorganisms in the soil. . Contents of the invention [0003] The purpose of the present invention is to solve the imbalance of nutrients in the organic ...
