Embodiment 1

[0022] Embodiment 1 A kind of method that improves postharvest quality and shelf life of kale

[0023] 1. Experimental design

[0024] Under the conditions of plastic greenhouses, coconut bran substrates were used to raise seedlings. 15 days after sowing, the kale seedlings with 3 leaves and 1 heart were transplanted into the cultivation substrate bag, and sprayed with conventional nutrient solution. 10 days with blue light (430±10nm) 50±5μmol·m -2 ·s -1 , 7:00-19:00 light supplement, after the kale was harvested, it was stored in the dark at a room temperature of 15°C and a relative humidity of 85%, and samples were taken and analyzed 2, 4, and 6 days after storage.

[0025] 2. Determination and method of quality indicators

[0026] 2.1 Determination of postharvest weight of kale

[0027] Weight loss (%) = (W 0 -W t )×100 / Wt

[0028] W 0 : weight at harvest; W t : the weight of day t after harvest, the results are shown in Table 1, blue light supplement light can red...

Abstract

The invention discloses a method for improving postharvest quality and prolonging shelf life of cabbage mustard, and belongs to the technical field of vegetable planting. The method comprises the following specific steps of carrying out light supplementation with blue light with the illumination intensity of 50+ / -5 mu mol.m<-2>.s<-1> and the wavelength of 430+ / -10 nm for 10 days before harvestingof the cabbage mustard cultivated in a substrate under the condition of a plastic greenhouse, the postharvest weight loss of the cabbage mustard is reduced through blue light supplementation, and thehigh chlorophyll content of the cabbage mustard and the green and brightness of leaves are kept; blue light supplementation maintains high soluble protein, vitamin C, total polyphenol and flavonoid content of the cabbage mustard, and maintains high FRAP antioxidant activity; and blue light supplementation before harvesting of the cabbage mustard is beneficial for maintaining nutritional quality, oxidation resistance and shelf life of the harvested cabbage mustard. Compared with the prior art, the method is low in cost, simple in operation method and easy to popularize, can be directly appliedto production, and has good economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of vegetable planting, and in particular relates to a method for improving postharvest quality and shelf life of kale. Background technique [0002] Kale, also known as: white flower kale, green leafy cabbage, kale (Guangdong), kale, and Gai Cai, is an annual herb of the genus Brassica in the family Brassicaceae. It has a long history of cultivation and is one of the specialty vegetables in China. The cabbage sprouts of kale are tender, crisp, sweet, and delicious. They are eaten with fat and tender flower stalks and young leaves. Kale contains cellulose and sugar. The edible part of kale is the stalk with leaves. Because kale contains a lot of starch, the taste is not soft enough, but it is very crisp and has a unique flavor. [0003] As a leafy vegetable, kale has a large leaf surface area and high water content. After harvesting, its physiological metabolism is vigorous, and it is prone to leaf yellowing...
