Abstract

The present invention relates to a method for increasing selenium content in fruits, the selenium content in fruits is increased by a conducting method of a fruit tree root self-absorbing liquid fertilizer in the young fruit period, or the selenium content in fruits is increased by liquid fertilizer which is directly sprayed on braches, leaves and fruits of a fruit tree and is absorbed. The present invention has the advantages of scientific method, simple and easy operation, convenient operation and easy control; the selenium content in fruits can be effectively increased, and can be easily absorbed by a human body; the fruit tree has no any inhibitory action or adverse reaction, and the method can be widely used for various fruit trees, such as a jujube tree, an apple tree, a grape tree, a peach tree, an apricot tree, a Chinese chestnut tree, a walnut tree, a pear tree, a banana tree, etc.

Description

Improve the method for fruit Se content

Technical field

The present invention relates to processing method technical field to trees in the growth.

Background technology

Selenium is the element of needed by human, and human body lacks selenium can cause depauperation, feeblemindedness, and immunologic function and phagocytic activity of leukocytes descend, and easily suffer from various diseases such as Kaschin-Beck disease, Keshan disease, cardiopathy, cancer.It is just unlikely unhealthful that experimental data proof adult takes in Se 25 μ g-150 μ g when per, and children are about 10-100 μ g just can make its normal development.Approach to the human body Selenium Supplement has two: the one, take the selenium agent medicine, and because selenium may cause poisoning, it is unsuitable taking the selenium agent medicine, only sees at present to be added in the feed stripped.The 2nd, the food of edible rich selenium.There is the people that selenate is added in the chicken feed recently, produce on " high energy egg ", behind the cardiovascular edible for patients, obtain unusual good curative effect, it also is an important benefit selenium approach that edible fruit replenishes human body selenium element, but selenium content is all lower in the fruit, is 0.001ppm as the apple selenium content, red date is 0.003ppm, and it is impossible replenishing enough selenium elements by this approach.Add from soil if improve the Se content of fruit, because sodium selenite has stronger toxicity, plant crosses separating/enriching to selenium may cause murder by poisoning, and influences phosphatic absorption.

Summary of the invention

The purpose of this invention is to provide a kind of method that improves the fruit Se content, it is by the daily edible rich selenium fruit of people, the selenium element that additional needed by human body is wanted, reach the purpose of raising immunity and diseases prevention, anti-cancer, the inventive method science is simple and easy to do, easy to operate easy control, can effectively improve Se content in the fruit, and to fruit tree unrestraint effect and bad reaction, applicable to multiple fruit tree, applied range.

The present invention is achieved in that a kind of method that improves the fruit Se content, it is at the fruit young fruit period, adopt the fruit tree tree root of a thick 10-30mm all around, cut and stay one section, root is inserted in the container that contains the sodium selenate aqueous solution, utilize self-priming conduction method to improve the Se content of fruit, solution can use the aqueous solution that contains sodium selenite 0.01-0.05%, and solution usage is the per kilogram fresh weight, comprises stem, root, leaf fruit, the 3-5 milliliter, once or gradation use.Also can use other selenium element aqueous solution.

The Ge that contains 0.02-0.1% in the above-mentioned solution is good, and Ge can effectively improve the absorption ratio of Se, and is beneficial element.B can reduce fruit drop rate.

Preferably add glucose 0.5%, nitrogen 0.3% or boron 0.3% in the aqueous solution.

The another kind of method that improves the fruit Se content is at young fruit period the liquid fertilizer for preparing to be sprayed on fruit tree branch, leaf, the fruit, utilize its absorption to increase selenium and element ge in the fruit, contain Se and Ge element in the liquid fertilizer, its concentration is Se 200-250 μ g/g water, Ge 200-500 μ g/g water, active bleeding agent 10000-20000 μ g/g water.

Also can contain the B ion in the liquid fertilizer, its concentration is 5000-1000 μ g/g water.

According to the fruit that above-mentioned method obtains, its Se content is a 0.1-0.3 μ g/g fruit, or Se content is 0.1-0.3 μ g, and Ge 0.1-1 μ g/g really is good.

Advantage of the present invention is, science, simple and easy to do, and easy to operate easy control, cost is low, and the selenium in the resulting fruit easily makes absorption of human body, and fruit tree is not had any inhibitory action and bad reaction.First method, effect is fast, not only can increase selenium, germanium, also can be used for increasing other elements such as compositions such as Ca, Zr, and solution concentration is fixed by assimilation effect.Second method is owing to be furnished with suitable Ge, its proper proportion in the liquid fertilizer, than effective with the Se element separately, absorb soon, absorption ratio can bring up to 50%, absorption ratio height, and Ge also is a kind of beneficial element to the person also has the effect that improves immunity and diseases prevention, anti-cancer.Also can add B in liquid fertilizer or in the aqueous solution, to reduce fruit drop rate.The present invention can be widely used in multiple fruit trees such as jujube, apple, grape, peach, apricot, Chinese chestnut, walnut, pears, banana.

Embodiment

Be described further below in conjunction with embodiment, but not as a limitation of the invention.

Embodiment 1:

The 5 years life 240 strain apple trees in orchard are divided into three groups, first group, the contrast of second group.To the first group 3 milliliters of the sodium selenite aqueous solution per kilogram fresh weights of young fruit period self-priming conduction 0.015%.To the second group 5 milliliters of the sodium selenite aqueous solution per kilogram fresh weights of young fruit period self-priming 0.02%.Three groups of maturing stage fruit picking chemical examinations, its result of laboratory test is as follows:

The check item	Contrast	The first group	The second group
The check item	Contrast	The first group	The second group	Se(μg/g)	0	0.11	0.3

Also identical with 0.05% sodium selenite aqueous solution test effect.

Embodiment 2:

5 years green apples of 180 strains tree is divided into three groups, and the sodium selenite aqueous solution and the time of contrast, first group, the suction of second group are the same, in the aqueous solution of first group sodium selenite, add 0.5% glucose and 0.3% boron 0.3% nitrogen.Its apple result of laboratory test is:

The check item	Contrast	The first group	The second group
The check item	Contrast	The first group	The second group	Se(μg/g)	0	0.147	0.3
