Embodiment 1

[0034] Embodiment 1, the preparation that is used to control fruit postharvest disease

[0035] Adjust the concentration of Rhodosporidium marinum to 1 × 10 8 cells / mL, after sterilizing at 121°C for 20 min, the inactivated cell suspension of Rhodosporidium marinum was obtained.

[0036] Take 1L marine Rhodosporidium inactivated cell suspension, add sterile water to dilute. Until the resulting 1L preparation contains 1×10 8 ~1×10 10 A rhodosporidium yeast inactivated bacterial cells, the rest is water (sterile distilled water); a preparation for inducing fruit resistance and controlling diseases is obtained.

[0037] In order to prove the actual use effect of the preparation of the present invention, the inventor has carried out following experiments:

[0038] Experiment 1. Induction effect of inactivated yeast cells on pear fruit blue mold resistance

[0039] 1. Experimental materials:

[0040] The fruit is crystal pear.

[0041] Pathogen: Penicillium expansum, activat...

Abstract

The invention discloses a preparation for controlling diseases by inducing fruit resistance. 1*10<8>-1*10<10> rhodosporidium inactivated bacterium cells are contained in 1 L of the preparation. Rhodosporidium is sea Rhodosporidium paludigenum Fell&Tallman with the preservation serial number of IMI 394084. The invention further discloses a method for using the preparation to control diseases by inducing fruit resistance. The method comprises the steps that before fruits are cartooned for storage, pretreatment is carried out in any following mode first, wherein according to a first pretreatment mode, the fruits are put into the preparation to be soaked, drained and then put into a container to be stored for 23-25 h in a sealed state; according to a second pretreatment mode, before the fruits are picked, the preparation is sprayed to the surfaces of the fruits, and then the fruits are put into a container to be stored for 23-25 h in a sealed state; the pretreated fruits are taken out of the container and then cartooned.

Description

technical field [0001] The invention relates to the technical field of prevention and control of post-harvest fruit diseases, in particular to a biological fresh-keeping technology for suppressing post-harvest fruit diseases by inducing fruit resistance. Background technique [0002] The loss of fruit due to rot after harvest is very huge. According to the data, the annual fruit and vegetable rot in my country exceeds 80 million tons, causing economic losses of 100 billion yuan. The infection of pathogenic fungi is the main cause of postharvest fruit rot. The common pathogenic fungi mainly include Penicillum spp., Botrytis spp. and Alternarias pp. and so on. [0003] At present, chemical fungicides are still the main measures to control postharvest diseases of fruits. Taking citrus as an example, the Chinese invention patent (application number 200910028802.2, citrus fresh-keeping agent) provides a variety of chemical fungicides that can control citrus diseases, including t...
