Selenium-rich kiwi fruit production method

Abstract

A selenium-rich kiwi fruit production method includes: applying a selenium fertilizer for 2-3 times during a production process of kiwi fruit, adding 30 kg of water into 180-250 ml of selenium-rich organic fertilizer liquid / 667 m<2>, spraying the front surfaces and the back surfaces of leaves with the diluted selenium-rich organic fertilizer liquid during 10-15 days after fruiting of kiwi plants, and allowing the content of selenium in fruit pulp of the kiwi fruits to reach 0.030-0.100 mg / kg via growth. The use method includes: a, the content of selenium of the selenium fertilizer is greater than or equal to 6g / L; b, the use time is about half month after fruiting of the kiwi plants; c, the use method is leaf spraying, and the front surfaces and the back surfaces of the leaves are sprayed; the use amount is 180-250 ml / 667 m2 with adding 30 kg of water, even spraying is preformed, and spraying is performed for 1-2 times again after 10-15 days; e, re-spraying should be performed in rain day during 4 hours after spraying. The method can promote the normal growth of fruits, the skin color of the fruits is even and bright, the sugar of the fruit pulp is increased, the fruit appearance and the nutritional quality can be improved, and the content of selenium in fruit pulp of the kiwi fruits to reach 0.030-0.100 mg / kg.

Description

technical field [0001] The invention relates to a fruit production method, in particular to a method for producing selenium-enriched kiwifruit by using selenium-enriched organic liquid fertilizer. Background technique [0002] Kiwi fruit is native to China, also known as kiwi fruit, fox peach, vine pear, sheep peach, muzi, mao fruit, ma vine fruit, yangtang pear, etc. The fruit shape is generally oval, and the early appearance is greenish brown. Reddish-brown, inedible, densely downy skin, containing bright green flesh and a row of black or red seeds. Kiwi fruit is fresh and tender in quality, soft in texture, sweet and sour in taste, rich in nutrition and delicious in flavor. In addition to containing organic substances such as actinine, proteolytic enzymes, tannin pectin and sugars, as well as trace elements such as calcium, potassium, selenium, zinc, germanium and 17 kinds of amino acids needed by the human body, it is also rich in vitamin C and grape acid. , fructose, ...

Problems solved by technology

At present, the commonly used selenium supplement methods for the human body mainly include taking sodium selenite, eating selenium salt, etc., but because these methods are difficult to control the intake and have potential toxicity and other reasons, they have obvious limitations; people from the perspective of long-term and safety We are discussing the production of selenium-enriched agricultural products, so that people can supplement selenium through diet, so that selenium can enter the human body through the food chain; a large number of experiments have proved that this is an effective way to supplement selenium
