Embodiment 1

[0017] Embodiment 1: Lactobacillus plantarum (Lactobacillus plantarum P-8) and Lactobacillus casei (Lactobacillus casei) Zhang increase the test of β-carotene content in carrot

[0018] Experimental site: Laixidianbu Houtun (Lactobacillus plantarum group, Lactobacillus casei group, compound bacteria group and blank control group each 1.7 mu)

[0019] Planting management: The size of the shed is 115m long and 10m wide. There are 13 ridges per shed, 2 rows of radishes are planted on each ridge, and the plant spacing is 5-6cm. Base fertilizer per shed: potassium sulfate compound fertilizer (N:P:K is 15:15 : 15) 300 catties, 600-700 catties of organic fertilizer, no top dressing in the later stage.

[0020] Experiment time: 2016.04.26-2016.6.23

[0021] Experimental crop: carrot (variety: Mendel 808)

[0022] Dosage and method: After the carrot sowing finishes, immediately drip irrigation with the microbial inoculum (the total number of live bacteria in the inoculum used by the ...

Embodiment 2

[0034] Embodiment 2: Lactobacillus plantarum (Lactobacillus plantarum P-8) and Lactobacillus casei (Lactobacillus casei) Zhang increase the test of β-carotene content in carrot

[0035] Experimental location: Houtun, Laixidian, (1.7 mu for each of the experimental group and the control group)

[0036] Planting management: the experimental group and the control group are about 1.7 mu each, the size of the shed is 115m long and 10m wide, each shed has 13 ridges, 2 rows of radishes are planted on each ridge, the distance between plants is 5-6cm, and the base fertilizer is applied to each shed: potassium sulfate compound fertilizer (N:P:K is 15:15:15) 300 catties, 600-700 catties of organic fertilizer, no top dressing in the later stage.

[0037]Experiment time: 2016.04.26-2016.6.23

[0038] Experimental crop: carrot (variety: Noli red)

[0039] Dosage and method: After the carrots are sown, drip-irrigate the microbial agent with the water (the ratio of the number of the two bact...

Abstract

The invention discloses a composite inoculant capable of increasing the content of beta-carotene in carrots and application of the multiple species inoculant. The inoculant is composed of Lactobacillus plantarum P-8 and Lactobacillus casei Zhang. The Lactobacillus plantarum P-8 and the Lactobacillus caseei Zhang have an obvious influence on growth and metabolism of the carrots and particularly can synergistically increase the content of the beta-carotene in the carrots, ideal raw materials are provided for preparation of natural carotene, the production cost of the beta-carotene is reduced, and the yield and the benefit are increased.

Description

technical field [0001] The invention relates to a microbial bacterial agent, in particular to a bacterial agent capable of significantly increasing the content of beta-carotene in carrots, and belongs to the technical field of microorganisms. Background technique [0002] With the development of the economy, the progress of society and the continuous acceleration of the pace of life, people are now under greater pressure in all aspects of work and life. While doing normal exercise and health care, more and more consumers are also Appropriate nutritional supplementation. [0003] β-carotene is one of the carotenoids and is also an orange-yellow fat-soluble compound. It is the most ubiquitous and stable natural pigment in nature. Many natural foods such as: green vegetables, sweet potatoes, carrots, spinach, papaya, mango, etc. are rich in β-carotene, but the most abundant ones are in carrots. β-carotene is an antioxidant with very strong antioxidant properties, which can pr...
