Problems solved by technology

Therefore, selenium is called the "king of anti-cancer" among human trace elements by scientists. Selenium can be used as a trace additive for animal feed, and can also be added as trace element fertilizer in plant fertilizers. Selenium products, such as selenium-enriched apples and selenium-enriched tea, usually only increase the selenium content of plants by spraying sodium selenite solution. Can't keep up, affects the absorption rate, and there is no report about the special selenium-enriched fertilizer for pear trees in the prior art

Embodiment 1

[0012] Fully dissolve 20 parts of magnesium sulfate, 5 parts of zinc sulfate, 10 parts of copper sulfate, 10 parts of iron sulfate, 10 parts of urea, 8 parts of potassium sulfate, 10 parts of potassium dihydrogen phosphate and 25 parts of sodium selenite in water (dilution factor 1000 times), and mix evenly to get the nutrient solution. The nutrient solution that will make is used for pear tree, and implementation method is as follows:

[0013] Application group: the prepared nutrient solution was applied to 100 pear trees, and the roots were watered.

[0014] Control group: 100 pear trees were irrigated with the same amount of water for the roots

[0015] When the fruit is ripe, the selenium content is detected respectively. The selenium content of the application group reached 15ug / kg, while the selenium content of the control group was only 2ug / kg, and the average net fruit weight of the application group was 15% higher than that of the control group. During the growth p...

Embodiment 2

[0017] Fully dissolve 30 parts of magnesium sulfate, 15 parts of zinc sulfate, 15 parts of copper sulfate, 25 parts of iron sulfate, 25 parts of urea, 15 parts of potassium sulfate, 15 parts of potassium dihydrogen phosphate and 40 parts of sodium selenite in water (dilution factor 1500 times), and mix evenly to get the nutrient solution. The nutrient solution that will make is used for pear tree, and implementation method is as follows:

[0018] Application group: the prepared nutrient solution was applied to 100 pear trees, and the roots were watered.

[0019] Control group: 100 pear trees were irrigated with the same amount of water for the roots

[0020] When the fruit is ripe, the selenium content is detected respectively. The selenium content of the application group reached 40ug / kg, while the selenium content of the control group was only 8ug / kg, and the average net fruit weight of the application group was 20% higher than that of the control group. During the growth...

Embodiment 3

[0022] Fully dissolve 20 parts of magnesium sulfate, 10 parts of zinc sulfate, 10 parts of copper sulfate, 15 parts of iron sulfate, 10 parts of urea, 15 parts of potassium sulfate, 15 parts of potassium dihydrogen phosphate and 35 parts of sodium selenite in water (dilution factor 1200 times), and mix evenly to get the nutrient solution. The nutrient solution that will make is used for pear tree, and implementation method is as follows:

[0023] Application group: the prepared nutrient solution was applied to 100 pear trees, and the roots were watered.

[0024] Control group: 100 pear trees were irrigated with the same amount of water for the roots

[0025] When the fruit is ripe, the selenium content is detected respectively. The selenium content of the application group reached 30ug / kg, while the selenium content of the control group was only 5ug / kg, and the average net fruit weight of the application group was 18% higher than that of the control group. During the growth...

Abstract

The invention discloses a selenium-rich nutrient solution for a pear. The nutrient solution comprises, by weight, 20 to 30 parts of magnesium sulfate, 5 to 15 parts of zinc sulfate, 10 to 15 parts of copper sulfate, 10 to 25 parts of iron sulfate, 10 to 25 parts of urea, 8 to 15 parts of potassium sulfate, 10 to 15 parts of potassium dihydrogen phosphate and 25 to 40 parts of sodium selenite. Through application of the nutrient solution provided by the invention, selenium content of the pear can be substantially increased, production of the pear is promoted, net weight of fruit is increased, resistance of the pear to insect attack is enhanced, and attack by diseases and insect pests is reduced.

Description

technical field [0001] The invention relates to a nutrient solution for fruit trees and an application thereof, in particular to a selenium-enriched nutrient solution for pear trees and an application thereof. Background technique [0002] Selenium is an important component of some antioxidant enzymes (glutathione peroxidase) and selenium-P protein in animals and humans. It plays a role in balancing the redox atmosphere in the body. Selenium has been used as an essential trace element for the human body , studies have proved that it has the effect of improving animal immunity. In the world, the research on the effect of selenium on immunity and cancer prevention is a hot issue in this field. The role of selenium is relatively broad. There are two main principles: first, the composition of antioxidant Enzymes can protect cell membranes from oxidative damage and maintain their permeability; secondly, selenium-P protein can chelate toxic substances such as heavy metals and redu...
