Problems solved by technology

[0003] Biological soil remediation agents and treatments are one of the important remediation methods for continuous cropping obstacles. In the past, the effective number of applications was used to affect the soil microbial population, and the colonization and reproduction of soil beneficial bacteria required the accumulation of the number of flora, and In the process of plant growth, if the reproduction rate of soil remediation beneficial bacteria is lower than the consumption rate, the application effect of soil remediation agent will be greatly reduced. Therefore, it is necessary to continuously supplement probiotics and optimize the soil environment of probiotics.

Embodiment 1

[0028] Embodiment 1 is used to repair the irrigation method of melon crop continuous cropping soil microbial flora

[0029] (1) Preparation of biological bacteria agent

[0030] The biological agent is the fermentation liquid of Burkholderia phytofirmans, the Burkholderia phytofirmans, depository unit: China Microbial Cultures Preservation Committee General Microbiology Center, address is Beichen West, Chaoyang District, Beijing Road No. 1 Yard No. 3, Institute of Microbiology, Chinese Academy of Sciences, the preservation number is CGMCC No.15326, the strain number is 20180101Liao CK1, and the preservation date is January 29, 2018;

[0031] The formula of the biological agent culture medium includes: tryptone 5g / L, yeast extract 5g / L, seaweed fertilizer powder 10-30g / L, cornstarch 2-5g / L, adjust the pH to neutral; the culture medium is sterilized Finally, inoculate Burkholderia and carry out fermentation, the fermentation temperature is 28 ℃, the stirring speed is 120rpm, an...

Embodiment 2

[0040] Greenhouse field application test

[0041] (1) Test time: 2018.

[0042] (2) Experimental crop: muskmelon, variety: Pengshuai Tianwang (Cangzhou Chunfeng Seed Industry Co., Ltd., Hebei).

[0043] (3) Continuous cropping period: 3 years.

[0044] (4) Processing 1 adopts embodiment 1 to be used for repairing the irrigation method of melon crop continuous cropping soil microbial flora, and biological bacteria Burkholderia concentration 1 * 10 in the described irrigation water and fertilizer 2 -1.0×10 3 cfu / ml, seaweed fertilizer 0.001-0.008g / L; treatment 2 is the control normal irrigation water, and the test period is the whole growing season of the crops.

[0045] (5) The rest are cultivated and managed normally.

[0046] (6) Effects of irrigation methods used to repair the microbial flora of continuous cropping soil of melon crops on the content of phenolic acids in continuous cropping soil

[0047] One month, two months, three months, and four months after the melo...

Abstract

The invention relates to an irrigation method for repairing soil microbial flora in continuous cropping of melon crops, comprising the following steps: (1) preparing Burkholderia biological agent; (2) mixing load particles; (3) preparing irrigation Water and fertilizer, the bacteria concentration of Burkholderia in the irrigation water and fertilizer is 1×10 ‑1 ×10 3 cfu / ml, seaweed fertilizer 0.0001-0.01g / L; (4) Apply irrigation water and fertilizer, the irrigation water and fertilizer adopts the method of hose drip irrigation, and the amount of water and fertilizer irrigation is 7-15 cubic meters per mu. The method uses irrigation water containing repairing probiotics to irrigate crops, continuously repairs continuous cropping soil, reduces the growth rate of phenolic acid substances in crop soil, increases the richness and diversity of microbial populations in the soil, has a good repair effect, and simultaneously promotes crop growth and resistance. Disease, increase the number of female flowers of melon plants.

Description

technical field [0001] The invention relates to the field of soil microbial flora restoration, in particular to an irrigation method for continuous restoration of soil microbial flora for continuous cropping of melon crops. Background technique [0002] The obstacle of continuous cropping has always been an important reason for restricting the yield of greenhouse crops. The reason for the obstacle of continuous cropping is very complicated and is the result of the combined effect of many factors. Studies have shown that autotoxicity and soil microbial flora imbalance are important factors for continuous cropping obstacles. Among them, microbial activity and diversity are important indicators to measure soil health. Soil microorganisms are extremely sensitive to changes in the external environment. Diversity changes, beneficial bacteria decrease, and harmful bacteria increase, resulting in obstacles to continuous cropping. [0003] Biological soil remediation agents and tre...
