Embodiment 1

[0033] Embodiment 1, a kind of soil conditioner

[0034] (1) Composition of soil conditioner

[0035] By weight, the soil conditioner includes the following raw materials: 1500 parts of montmorillonite-humic acid complex, 0.5 parts of chelated iron and 0.5 parts of chelated zinc, 15 parts of composite bacterial agent and compound amino acid stock solution as binder .

[0036] Among them, the composite bacterial agent is composed of AMF bacterial agent (arbuscular mycorrhizal fungal bacterial agent) and bacillus, and the number of viable bacteria in the composite bacterial agent is ≥ 2 billion / g. The ratio of AMF bacterial agent and Bacillus in the compound bacterial agent used is 1:1. In this embodiment, the AMF inoculum is a Rhizocystis intraradices (R. intraradices) inoculum, and the Bacillus is a Bacillus subtilis inoculum.

[0037] In this embodiment, the chelated iron is sodium ferric EDTA, and the chelated zinc is disodium zinc EDTA.

[0038] The addition amount of t...

Embodiment 2

[0049] Embodiment 2, soil improvement experiment

[0050] (1) Implementation location:

[0051] The experiment was carried out in the multi-span greenhouse of Beijing Academy of Agriculture and Forestry Sciences, which is located inside the Beijing Academy of Agriculture and Forestry Sciences (39°94′88″N and 116°29′08″E) in Shuguang Garden, Haidian District. It has a continental monsoon climate with sufficient light and heat, with an average annual temperature of 10-12°C and an average annual rainfall of 664mm. Built since 2010, with an area of ​​10,000m 2 , Since its establishment has been the anniversary production facility vegetables.

[0052] (2), test treatment:

[0053] The soil conditioner obtained in 5 gradient application examples 1 is set, respectively 0, 1500kg / ha, 3000kg / ha, 4500kg / ha, 6000kg / ha (corresponding to T1, T2, T3, T4, T5 treatment respectively). Area of ​​test plot: 20(3*6.6)m 2 , each treatment set three replicates, each test area is 60m 2 , becau...

Abstract

The invention discloses a soil conditioner which is characterized by being prepared from the following raw materials in parts by weight: 1500 parts of montmorillonite-humic acid complex, 0.5 part of chelated iron, 0.5 part of chelated zinc, 15 parts of complex microbial inoculants and a compound amino acid stock solution serving as a binder. The soil conditioner is simple in preparation method, raw materials are easy to obtain, implementation is convenient, the soil conditioner contains nutrient elements and nutrient coordination substances needed by northern facility tomato soil, the soil health condition can be effectively improved, the tomato yield can be increased, tomato quality improvement can be promoted, and the soil conditioner is suitable for large-scale popularization and application. Powerful support is provided for green and sustainable development of the northern facility tomato industry.

Description

technical field [0001] This application relates to the technical field of soil remediation, in particular to a soil conditioner and its application. Background technique [0002] my country's large-scale facilities such as greenhouses and greenhouses account for more than 85% of the world's production area of ​​facility agriculture. The long-term high-input, high-output production model has led to the deterioration of my country's facility soil ecological environment, such as soil acidification, secondary salinization, and continuous cropping obstacles. It leads to the decline of vegetable yield and quality and the aggravation of pests and diseases, which seriously hinders and threatens the sustainable development of facility agriculture. The application of soil conditioners is one of the important measures to restore degraded soil. The research on soil conditioners began at the end of the 19th century, and there are many types. The composition, properties and mechanism of ac...
