Problems solved by technology

[0004] The current selenium-enriched fertilizers usually add selenium ore powder or sodium selenite powder directly to the fertilizer, in which the selenium element exists in the form of inorganic selenium, and in order to blindly pursue the selenium content of crops, selenium fertilizers are often used in large quantities or before maturity. Increasing the amount of selenium fertilizer will lead to the complete conversion of inorganic selenium in crops in the future, and the content of inorganic selenium is high, which is not suitable for human body absorption

Embodiment 1

[0029] A kind of preparation method of selenium-enriched fertilizer special for kiwifruit, is characterized in that, comprises the steps:

[0030] (1) Wash and sterilize the broken catharina seeds, wash and soak them with deionized water for 46 hours to promote their germination, and use deionized water to avoid excessive metal ions in the water from affecting the germination of the broken catkin seeds;

[0031] (2) bury the soaked seeds in the soil, keep the soil temperature at 28.5°C, and wait for them to germinate;

[0032] (3) When 3-5 leaves are grown from the seedlings of the broken rice chestnuts, take them out, transfer them to the complete nutrient solution and cultivate them for 4 days, keep sufficient light during the cultivation process, and ventilate the nutrient solution for 10 minutes every 1 hour to make them rapidly growing up;

[0033] (4) Transfer the broken rice chestnut seedlings to the selenium-enriched nutrient solution containing sodium selenite 50mg / L...

Embodiment 2

[0039] A kind of preparation method of selenium-enriched fertilizer special for kiwifruit, is characterized in that, comprises the steps:

Abstract

The invention belongs to the field of fertilizers and especially relates to a selenium-rich fertilizer special for kiwi fruit and a preparation method thereof. The method comprises the following steps: adopting a selenium-rich nutrient solution for culturing cardamine hirsuta, mixing the cultured selenium-rich cardamine hirsute with humic acid, boric acid, calcium superphosphate, urea and potassium sulfate at ratio, and then co-heating and stirring, thereby acquiring the selenium-rich fertilizer special for kiwi fruit that is capable of promoting the growth and development of the plants, restoring soil pollution and supplying a large amount of organic selenium to the kiwi fruit. The selenium-rich fertilizer special for kiwi fruit, provided by the invention, can be applied for obviously increasing the selenium content, especially, organic selenium content of the kiwi fruit.

Description

technical field [0001] The invention belongs to the field of fertilizers, in particular to a special selenium-enriched fertilizer for kiwi fruit and a preparation method thereof. Background technique [0002] Selenium is a chemical element whose chemical symbol is Se. It is located in group VI A of the fourth period of the chemical element periodic table and is a non-metal. Selenium is an essential trace element for humans and animals. Selenium deficiency will seriously affect human health. In 1972, Roetueh confirmed that selenium is the active ingredient of glutathione peroxidase (GPX). Since then, selenium has been recognized as an essential trace element for life. Selenium is also an essential nutrient element for the growth of higher plants. According to research, 0.1-1.0 μg / g can promote the growth of rice, increase yield and increase the selenium content in grains. Selenium at 1.0 μg / g can significantly increase the root activity of rice seedlings and the activity of...
