[0036] The slow-release layer is made up of the following materials: 15wt% of earthworm soil, 7.5wt% of soil anti-compaction agent (sodium alkylbenzene sulfonate), 7.5wt% of insecticidal component (dinotefuran), weeding granules (loaded with herbicide Ling's sepiolite) 25wt%, α-cyclodextrin 45wt%.

[0037] The mass ratio of the quick-release layer and the sustained-release layer is 1:4.

Embodiment 2

[0039] A multi-functional soil conditioner comprises an immediate-release layer and a slow-release layer sequentially from the inside to the outside.

[0040] The quick-release layer is made up of the following materials: 10wt% of earthworm soil, 10wt% of soil anti-compaction agent (sodium alkylbenzenesulfonate), 10wt% of insecticidal component (clothianidin), 10wt% of weeding granules (seaweed granules loaded with paraquat). foam stone) 30wt%, composite gel carrier 36.5wt%, modified calcium oxide 3wt%, povidone 0.5wt%.

[0041] The slow-release layer is made up of the following materials: 10wt% of earthworm soil, 10wt% of soil anti-compaction agent (sodium alkylbenzene sulfonate), 10wt% of insecticidal component (clothianidin), 10wt% of weeding granules (seaweed granules loaded with paraquat) pumice) 30wt%, β-cyclodextrin 40wt%.

[0042] The mass ratio of the quick-release layer and the sustained-release layer is 1:3.

Embodiment 3

[0044] A multi-functional soil conditioner comprises an immediate-release layer and a slow-release layer sequentially from the inside to the outside.

[0045] The quick-release layer is made up of the following materials: 20wt% of earthworm soil, 5wt% of soil anti-compaction agent (sodium alkylbenzene sulfonate), 5wt% of insecticidal components (thiacloprid, imidacloprid), weeding granules (loaded with amine, acetochlor sepiolite) 20wt%, composite gel carrier 43.5wt%, modified calcium oxide 5wt%, povidone 1.5wt%.

[0046] The slow-release layer is made up of the following materials: 20wt% of earthworm soil, 5wt% of soil anti-compaction agent (sodium alkylbenzene sulfonate), 5wt% of insecticidal components (thiacloprid, imidacloprid), weeding particles (loaded with beetle amine, acetochlor sepiolite) 20wt%, γ-cyclodextrin 50wt%.

Abstract

The invention relates to the field of agricultural planting, and discloses a multifunctional soil improvement agent and a preparation method thereof. The soil improvement agent comprises a quick-release layer and a slow-release layer. The quick-release layer consists of the following substances: earthworm soil 10-20wt%, a soil anti-hardening agent 5-10wt%, insecticidal constituents 5-10wt%, weeding particles 20-30wt%, a plural gel carrier 35-45wt%, modified oxidized calcium 3-5wt% and an adhesive 0.5-1.5wt%; and the slow-release layer consists of the following substances: earthworm soil 10-20wt%, a soil anti-hardening agent 5-10wt%, insecticidal constituents 5-10wt%, weeding particles 20-30wt% and cyclodextrin 40-50wt%. The multifunctional soil improvement agent can improve water-retaining property and breathability of soil, and has effects of killing insects, weeding and improving soil fertility, further has long-acting slow-release effect, and can continuously and stably release active ingredients.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a multifunctional soil conditioner and a preparation method thereof. Background technique [0002] Excessive fertilization of the soil will cause soil compaction, hardening, pH imbalance, poor air permeability, and decreased water retention capacity, making it difficult to meet the needs of planting. Soil amendments are mainly used to improve the physical, chemical and biological properties of soil to make it more suitable for plant growth. [0003] The Chinese invention patent with the notification number CN103788954A discloses a biochar-based soil conditioner. The soil conditioner in this invention includes biochar, and the biochar is pyrolyzed from biochar raw materials under oxygen-limited conditions. After the preparation, the biochar is applied through deep plowing to improve the poor white pulp soil quality. [0004] In the above patents, the adsorption of biochar is...
