Embodiment 1

[0027] Embodiment 1: The plant source-based soil conditioner is made of pine wood, and the preparation steps are: 1. lye soaking: the dried pine wood is pulverized, passed through a 60-80 mesh sieve, and soaked in a 2% NaOH solution by mass fraction After 48 hours, take it out, wash it with distilled water until it is neutral, and then dry it to obtain the biomass material; Pyrolysis and carbonization reaction, after holding for 30 minutes, heat up to 540-620°C at a heating rate of 8°C / min and hold for 70 minutes. When the temperature drops to 60°C, the material is coarsely crushed to obtain the biomass charcoal of the present invention; ③ Biomass liquid impregnation : The biochar of the present invention is immersed in the biomass liquid for 48h, dried, and processed to a diameter of 0.1-0.5mm to obtain the plant-based soil conditioner of the present invention. Its biological fluid is prepared by adding 400g of ficus leaves, 800g of walnut root, 580g of pihancao, and 650g of ...

Embodiment 2

[0028] Embodiment two: the plant-based soil conditioner is made of pine wood, and the preparation steps are: 1. lye soaking: the dried pine wood is pulverized, passed through a 60-80 mesh sieve, and soaked in a 2% NaOH solution by mass fraction After 48 hours, take it out, wash it with distilled water until it is neutral, and then dry it to obtain biomass materials; Raise the temperature to 290°C, carry out pyrolysis and carbonization reaction, and keep it warm for 30 minutes. At a heating rate of 8°C / min, raise the temperature to 540-620°C and keep it warm for 70 minutes. ; ③ Biomass liquid immersion: the biochar of the present invention is immersed in the biomass liquid for 48 hours, dried, and processed to a diameter of 0.1-0.5 mm to obtain the plant-based soil conditioner of the present invention. Its biological fluid is prepared by adding 400g of ficus leaves, 800g of walnut root, 580g of pihancao, and 650g of sour rattan wood into 180L of water, first boiling with strong...

Abstract

The invention discloses a preparation method of a plant source-based soil conditioner, and belongs to the technical field of soil conditioners. The plant source-based soil conditioner is prepared from pine by means of the steps of lye steeping, pyrolysis carbonization, biomass liquid dipping and the like. A field trial proves that the plant source-based soil conditioner has a better effect of conditioning soil.

Description

technical field [0001] The invention belongs to the technical field of soil conditioners, in particular to a plant-based soil conditioner. Background technique [0002] my country is a large agricultural country, which owns 10% of the world's arable land and consumes 30% of the world's chemical fertilizers. Severe soil acidification and compaction, especially in land degraded areas, where the original soil fertility foundation is poor, will lead to more compacted soil and the use of chemical fertilizers. The rate is reduced, which makes the soil nutrition unbalanced and the fertility decreases. Excessive residues of harmful substances such as chemicals, hormones, chloride radicals, and nitrites in chemical fertilizers will also damage the micro-ecological environment of the soil and seriously affect the health and safety of cultivated land. While increasing food production, it destroys the structure of the soil. Coupled with the discharge of industrial sewage and waste gas,...
