Description
Technical field
The present invention relates to fertilizer fields, and in particular to a kind of water-soluble fertilizer containing humic acid and its system for improving strawberry Se content
Preparation Method and application, it is especially useful in strawberry growth period absorbs selenium element, improves yield and pol.
Background technique
Selenium is one of the essential trace elements of the human body, it has anti-oxidant, anti-inflammatory, mitigates heavy metal in human body accumulation, mentions
The biological function of high body immunity facilitates anti-cancer, protection liver and protection eyesight etc., is known as " life kindling material ".
China soil is vast, and geology, landforms, natural environment and climate are complicated, in the case where the Chinese Academy of Agricultural Sciences organizes with all strength, China once into
Gone it is national about selenium distribution researching determining.According to investigation result, China have 72% regional selenium deficiency or poor selenium, have 2/3
Population selenium insufficiency of intake, about 700,000,000 people are in low selenium band.Southeastern coast is China's selenium-enriched area, also only 0.1ppm, is joint
Minimum as defined in state's health organization.
And amino acid rich in, fructose, sucrose, glucose, citric acid, malic acid, pectin, Hu Luo in strawberry fruit
Bu Su, vitamin B1、B2, niacin and mineral calcium, magnesium, phosphorus, potassium, iron etc., these nutrients have good promotion to growth and development
Effect.There are two types of approach for strawberry selenium-rich: Soil accumulation and fertilizer supplement.But China's most area selenium deficiency or poor selenium, therefore, from
Just become inevitable approach in fertilizer for strawberry Selenium Supplement.Using strawberry in leaf stretching period and full-bloom stage to the absorbability of selenium
Strongest feature supplements selenium element for it.Meanwhile selenium element is distributed at most in seed, and the seed of strawberry is distributed in fruit
Surface can be absorbed by the body more using part.
Summary of the invention
An object of the present invention, which is to provide one kind, to promote strawberry to grow, and improve yield, and can improve strawberry fruit
The dedicated water-soluble fertilizer containing humic acid of pol and Se content.
