Embodiment 1

[0027] 1 material preparation

[0028] The matrix materials are peat, coconut peat, vermiculite and perlite. Among them, the bulk density of peat is 0.1~0.5g·cm -3 , pH5.0~7, EC 0.1~5mS·cm -1 ;The bulk density of coconut bran is 0.1~0.25g·cm -3 , pH4.5~6, EC is 1.3~3.6mS·cm -1 ;The bulk density of vermiculite is 0.1~0.5g·cm -3 , pH6.8~8.0; the bulk density of perlite is 0.08~0.2g cm -3 , pH7.0~7.5.

[0029] In this embodiment, the purified arbuscular mycorrhizal fungus strain Glomus versiforme (Glomusversiforme, referred to as V bacteria, BGC number: YN05, resource platform number: 1511C0001BGCAM0013) was taken as an example to prepare a concentration of 4.35 × 10 8 CFU·L -1 The arbuscular mycorrhizal fungus spore suspension, explains the technical content of the present invention with this, but does not limit protection scope of the present invention thereby; All arbuscular mycorrhizal fungi are applicable to the present invention.

Embodiment 2

[0053] At pH, EC, bulk density and total porosity are 5.62, 2.67mS cm -1 , 0.2394g cm -3 , 54.37% mixed matrix, add 27L concentration 4.35×10 per cubic meter 8 CFU·L -1 The spore suspension of arbuscular mycorrhizal fungi was used for tomato seedling cultivation to propagate and activate arbuscular mycorrhizal fungi. After 30 days of seedling cultivation, cut off the aboveground part of the tomato, retain the root system and collect the seedling substrate, then add 4 times the mixed substrate (peat: coconut bran: vermiculite: perlite = 2:2:1) in the seedling substrate that retains the tomato root system : 1), mix well, and cultivate crops such as cucumber, tomato, Chinese cabbage, lettuce, spinach in the hole tray, with the peat that does not contain arbuscular mycorrhizal fungus: vermiculite=2:1 is CK1, with do not contain arbuscular mycorrhizal fungus Peat of mycorrhizal fungus: coconut peat: vermiculite: perlite = 2:2:1:1 is CK2. By measuring the growth indexes of the a...

Abstract

The invention discloses an organic substrate containing arbuscular mycorrhiza fungi and a preparing method and application thereof. A substrate containing arbuscular mycorrhiza fungi is obtained in the mode that on the basis of the organic substrate composed of peat, coconut chaff, vermiculite and perlite with the volume ratio of (1-50):(1-50):(0-50):(0-50), and the arbuscular mycorrhiza fungi symbiosis with tomato root systems is added. The organic substrate containing the arbuscular mycorrhiza fungi has the advantages that as the substrate contains the arbuscular mycorrhiza fungi, the biological characteristics of the substrate are improved, and fertility is improved; the growth promoting effect is obvious, and the seedling growing efficiency is improved; raw materials are easy to obtain, and the preparing method is simple; and the organic substrate containing the arbuscular mycorrhiza fungi is suitable for producing substrate products containing the arbuscular mycorrhiza fungi in a large scale mode.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular relates to an organic matrix containing arbuscular mycorrhizal fungi, a preparation method and application thereof. Background technique [0002] With the rapid development of protected horticulture, soilless culture technology and plug seedling technology are being popularized and applied on a large scale, which promotes the research, development and application of organic solid substrates. So far, peat is still the substrate with excellent physical and chemical properties, good cultivation effect, and can be used in large quantities. With the in-depth research on the resource utilization of industrial and agricultural waste, many safe, high-quality, convenient and good solid cultivation substrates have been continuously developed, synthesized and used, which has greatly promoted the development of organic substrate cultivation and soilless cultivation. Organic substrate is th...
