Embodiment

[0023] A method for keeping crisp and fresh persimmons, comprising the steps of:

[0024] 1) Establish a closed plastic greenhouse: the plastic greenhouse is sealed around the top and bottom, and there is a door on one side of the plastic greenhouse for entering and exiting the fruit. The plastic film used is 0.08-0.12mm thick PE greenhouse plastic film, The volume of the plastic greenhouse is 10m 3 , the amount of fruit processed in each batch is 2000-3000kg;

[0025] 2) Fumigation treatment: first put the picked persimmons into the plastic greenhouse, and put them in conventional stacking, then quickly put 2,4-dichlorophenoxyacetic acid and 1-methylcyclopropene into the plastic greenhouse, and seal them immediately Plastic greenhouse, fumigation treatment for 10-48h, wherein, the dosage of 2,4-dichlorophenoxyacetic acid is 10-20mg / kg, the concentration of 1-methylcyclopropene in the plastic greenhouse is respectively 0.5-5μL / L, and fumigation is carried out When processing...

Abstract

The invention discloses a method for keeping persimmon brittle and fresh. The method comprises the following steps: 1) building a closed plastic greenhouse; 2) fumigating, namely, placing the selected persimmon into the plastic greenhouse, stacking and arranging in general way, quickly adding 10 to 20mg / kg of 2, 4-dichlorphenoxyacetic acid and 0.5 to 5 microliter per liter of 1-methylcyclopropene to the plastic greenhouse, immediately sealing the greenhouse, and fumigating for 10 to 48 hours; 3) performing fresh keeping packaging treatment, namely, wrapping single fumigated persimmon with a foamed PE mesh sleeve, and then transferring into a packaging box formed by a polyethylene storage bag; 4) precooling, namely, precooling the packaging box for 12 to 24 hours under the temperature of -1 to 0 DEG C, wherein an opening of the polyethylene storage bag is completely opened during precooling; and 5) storing, namely, binding the opening of the polyethylene storage bag, and stacking and storing in a frozen warehouse at the temperature of 4+ / -0.5 DEG C. With the adoption of the method, the storage life of the persimmon can be increased to 9 to 10 months, and the effect of keeping brittle and fresh is good.
