Description

A kind of mango fruit orchard picking liquid and its application

technical field

The invention relates to the technical field of fruit picking treatment, in particular to a mango fruit orchard picking sealing liquid and its application.

Background technique

Mango (Mangifera indica) has the characteristics of bright and beautiful skin and flesh color, tender flesh, good flavor and strong aroma. It is very popular with consumers at home and abroad, and is known as the "king of tropical fruits". China is one of the main mango producing countries. Mango production is mainly distributed in Guangxi, Hainan, Guangdong and other provinces, and it is the main source of income for local farmers. However, mango picking is the most time-consuming and labor-intensive link in the mango production chain, accounting for about 40% of the entire production. The main manifestations are: when picking mangoes by hand, the method of "one fruit and two cuts" is generally adopted, that is, a 3-5 cm stem should be left for the first cut, and a 0.5 cm stem should be left for the second cut. The reason is that when mangoes are picked, the fruit stalks tend to overflow with juice, and milky white pulp will flow out. The amount of pulp is relatively large, reaching 10-30 ml, and sometimes it will flow out in a jet shape. Mango pulp is strongly acidic and highly corrosive. If it flows on the hands, it will cause discomfort or allergies. If it flows on the skin of the mango, it will form black spots on the skin and then rot. Therefore, mangoes need to be very careful during the process of picking, transporting and processing, which results in an increase in the cost of mango picking, transporting and processing. Simultaneously, because in the process of processing and transporting, fruit pedicel is easy to fall off, causes flow pulp, and then makes mango rot, has brought very big problem to fresh-keeping and prolonging shelf life of mango.

Contents of the invention

In order to solve the above problems, the present invention provides a mango fruit orchard picking slurry and its application, which improves fruit picking efficiency, reduces mango postharvest disease, is easy to operate, and is safe and environmentally friendly.

In order to achieve the above object, the technical scheme that the present invention takes is:

A kind of mango fruit orchard picking sealing liquid, which is prepared by stirring a certain amount of sodium hydroxide, alum, sodium carboxymethyl cellulose, Tween 80 and water; the content of sodium hydroxide in the picking sealing liquid The mass volume ratio concentration is 1-2%, the mass volume ratio concentration of alum is 0.05-0.1%, the mass volume ratio concentration of carboxymethyl cellulose sodium is 10-20%, the mass volume ratio concentration of Tween 80 is 0.1- 0.5%.

A mango fruit orchard picking sealing liquid, which is prepared by stirring a certain amount of calcium hydroxide, alum, sodium carboxymethyl cellulose, Tween 80 and water; the content of calcium hydroxide in the picking sealing liquid The mass volume ratio concentration is 1-2%, the mass volume ratio concentration of alum is 0.05-0.1%, the mass volume ratio concentration of carboxymethyl cellulose sodium is 10-20%, the mass volume ratio concentration of Tween 80 is 0.1- 0.5%.

The above-mentioned picking and sealing liquid can be used for the picking and sealing treatment of mango fruit, specifically implemented according to the following steps:

S1. When the mango is 7-8 years old, cut it off directly with the fruit handle, and collect it collectively, wherein the length of the fruit handle must be greater than 5 cm;

S2. After the concentrated collection is completed, pull out the fruit stalk on the mango directly, then quickly place the mango in the aqueous solution of sealing liquid, soak for 2-3 minutes, take it out, immediately spray and rinse it with clean water for 30 seconds, dry it, pack it and Store at room temperature.

The present invention has the following beneficial effects:

When the mango fruit treated with the sealing solution of the present invention was stored at normal temperature (22-25° C.) for 10 days, the disease was significantly alleviated, and the fruit disease index was reduced by 45-55% compared with the control, and the reduction range reached 64-78%. %, the commercial fruit rate is increased by 50-60% compared with the control, and the increase rate has reached 166-200%, which can effectively improve the picking efficiency, reduce mango fruit diseases, and is convenient to operate and easy to popularize. Simultaneously, sodium hydroxide, alum and sodium carboxymethylcellulose in the present invention are all food industry additives, and Tween 80 is the emulsifier of food industry, so there is no residual safety problem.

detailed description

In order to make the objects and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The severity of mango fruit disease in the following examples and matched groups is divided into 5 grades: 0 grade: no disease symptoms on the fruit surface; 1 grade: there are sporadic disease spots on the fruit surface; 25% of the area; Grade 3: the area of diseased spots on the fruit surface accounts for 25-50% of the total area of the fruit; Grade 4: the area of diseased spots on the fruit surface is greater than 50% of the total area of the fruit.

The formulas used include:

Disease index = [Σ(disease level value×number of diseased fruits)×100]/(highest disease level value×total number of fruits). According to the formula, the value of the disease index ranges from 0 to 100.

Commercial fruit rate=[(number of 0-grade fruits+1-grade fruits)×100%]/total number of fruits.
