Embodiment Construction

[0028] Put 500-600g of corncobs into a porcelain crucible after crushing them, cover and seal them, then place them in a muffle furnace for drying, raise the temperature up to 200°C at a rate of 10°C / min, and keep them warm for 2 hours to achieve pre-carbonization of corncobs; then Heat up to 600°C at the same heating rate for pyrolysis and carbonization for 3 hours, let it stand until the temperature drops to 60°C, and discharge the material to obtain carbonized corn cobs; take 1-2g potassium hydride, 50-60g caprolactone, 35-40g methyl Glycidyl acrylate and 2-4g benzyl alcohol were reacted at 50°C for 48 hours, then 1-2g 0.01mol / L hydrochloric acid was added to terminate the reaction, 80-100g n-hexane was added to produce a precipitate, and the precipitate was vacuum-dried for 24 hours to obtain degradable cross-linked Linking agent: take 1~2g poly N,N-dimethylaminoethyl methacrylate, 10~20g styrene, 1~2g degradable crosslinking agent, 5~10g toluene, 6~12g sorbitan Fatty acid...

Abstract

The invention relates to a preparation method of a soil improver, which belongs to the technical field of soil improvers. A corncob is carbonized to form a porous structure, so that the carbonized corncob is immersed in a degradable solution and then dried, the outer layer of the carbonized corncob is coated with a layer of netted degradable organic matter; since the degradable organic matter hasthe porous structure, the release rate of active ingredients in the soil improver can be reduced, and the sustainability can be improved; as the time goes by after the soil improver is applied to thesoil, the pores of the degradable organic matters on the outer layer are enlarged and increased, the degradable organic matters on the inner layer begin to be degraded, after the layer-by-layer degradation, the carbonized corncob can be reserved; and the soil improver prepared in the invention can adjust the pH value of the soil, can reduce the volume weight of the soil, can reduce the leaching loss of nitrogen, phosphorus and potassium in the soil, can supplement the content of organic carbon, can also overcome the weaknesses that the natural soil improver is poor in sustainability, and can be widely applied to the field of the preparation of agriculture environment-friendly soil improvers.

Description

technical field [0001] The invention relates to a preparation method of a soil improver, belonging to the technical field of soil improver. Background technique [0002] Agriculture is the most basic material production activity that human beings rely on for survival, and it is the main source of food and basic living guarantee for human survival activities. The sustainability, high yield, high efficiency and high quality of agriculture have gradually become the focus of modern agriculture. As a non-renewable natural resource and means of agricultural production, soil plays a crucial role in the agricultural ecosystem, directly affects various characteristics of agriculture, and is inseparable from agricultural production. [0003] Drought and water shortage are the most important limiting factors for agricultural production. Whether in arid and semi-arid areas or in humid areas with abundant rainfall, water stress caused by seasonal drought is the most critical factor limi...
