Description
Technical Field
The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a method for reducing the content of organic acid in wampee fruits.
Background
Clausena lansium (also known as King jar, Huangkui, Huang dui, Huang Feng, Huang Dan, is a plant of the genus Clausena of the family Rutaceae, and a fruit tree of the tropical subtropical evergreen color. The clausena lansium is native to south China, has been cultivated for more than 1500 years to date, and is mainly distributed in the Jinshajiang river valley areas of Guangdong, Guangxi, Hainan, Fujian, Yunnan, southern Guizhou, Sichuan and Taiwan in China. The wampee fruit is attractive in appearance, unique in flavor, sour, sweet and delicious, rich in sugar, organic acid, dietary fiber, various vitamins and trace elements and rich in nutrition. In addition, the wampee fruit also has important medicinal value, and the traditional Chinese medicine is used for treating cough, phlegm and asthma, cold, fever, difficult urination, malaria and other diseases. In recent years, with the progress of scientific research, active substances such as flavone, polyphenol, alkaloid and the like extracted from Chinese wampee have been proved to have the effects of resisting oxidation, viruses, tumors, senile dementia and the like. Therefore, as a functional health-care fruit, the Chinese wampee is more and more favored by consumers; under the current situation that the price of a large number of fruits in China fluctuates greatly, the sales price of the fresh wampee fruits steadily rises year by year, wherein the sales price of fine fruits is as high as 30-60 yuan/kg, and the fresh wampee fruits become a bright spot which is difficult to see in the fruit industry. Under the drive of high economic benefits, the yellow skin production in China is changed from sporadic planting after the former anterior chamber to large-scale commercial planting, the cultivation area is increased all the way, the development prospect is wide, wherein the yellow skin planting area in Yunan county of Guangdong province only reaches 8 ten thousand mu, the whole industry chain covers the industries and fields of planting, processing, packaging materials, transportation, catering, characteristic tourism and the like in the county, and the annual output value exceeds 10 million yuan. However, while the wampee industry is rapidly developed, the market also finds that the soluble solid content of common wampee fruits is not high, the taste is sour, and the quality is reduced, so that the consumption enthusiasm of the masses is reduced to a certain extent, and the sale price of the wampee fruits is greatly limited. Therefore, the invention is a method for reducing the organic acid in the Chinese wampee fruit, which is very urgent, not only is beneficial to improving the quality and market competitiveness of the Chinese wampee fruit, but also has great significance for improving the cultivation benefit of fruit growers.
Disclosure of Invention
The invention mainly aims at the problems of low soluble solid content and sour taste of the current common wampee fruits, and provides a method for reducing the organic acid content of the wampee fruits. In the process of the growth and development of the wampee fruits, the organic acid content in the wampee fruits is obviously reduced by spraying GABA aqueous solution on the wampee tree crowns. The method provided by the invention is easy to implement, has low cost and obvious economic benefit, and is worthy of popularization and application.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for reducing the organic acid content of wampee fruits comprises the following steps: and spraying GABA (gamma-aminobutyric acid) aqueous solution on the clausena lansium in the growth and development process of the clausena lansium fruits.
Preferably, the mass concentration of the GABA aqueous solution is 50-1000 mg.L-1。
Preferably, the mass concentration of the GABA aqueous solution is 100 mg.L-1。
Preferably, the method for reducing the organic acid content of the clausena lansium fruit comprises the following steps: spraying the GABA aqueous solution with the prepared concentration to the wampee tree from 30 days after the wampee is subjected to flower withering, spraying for 3-6 times, wherein the spraying interval is 7-10 days every time, and the spraying degree of the foliage wetting is adopted every time.
The invention has the technical effects that: in the invention, during the growth and development of the clausena lansium fruits, the clausena lansium is treated by spraying GABA medicament, thereby achieving the purpose of obviously reducing the total organic acid in the clausena lansium fruits. The method is simple and convenient to operate, does not generate any side effect, is low in implementation cost, has obvious economic benefit, has wide market prospect, and is worthy of popularization and application.
