Description
Technical field
The present invention relates to fertilizer field, be specifically related to a kind of improve Fructus Fragariae Ananssae Se content containing humic acid water-soluble fertilizer
And preparation method and application, it is especially useful in Fructus Fragariae Ananssae trophophase absorbs selenium element, improves yield and pol.
Background technology
Selenium is one of trace element of needed by human, and it has antioxidation, anti-inflammatory, alleviates heavy metal in human body
Accumulation, the biological function of raising body immunity, contribute to anti-cancer, the liver protecting and protection vision etc.,
It is described as " life kindling material ".
China soil is vast, and geology, landforms, natural environment and climate are complicated, under the Chinese Academy of Agricultural Sciences with all strength tissue,
China had once carried out the national researching determining about selenium distribution.According to survey result, there is the ground of 72% in China
District lacks selenium or lean selenium, has the population selenium Deficiency of Intake of 2/3, and about 700,000,000 people are in low selenium band.Southeastern coast is for I
State's district rich in selenium, the most only 0.1ppm, be the minimum that specifies of the United Nations's health organization.
And in strawberry fruit containing abundant aminoacid, fructose, sucrose, glucose, citric acid, malic acid,
Pectin, carotene, vitamin B1、B2, nicotinic acid and mineral calcium, magnesium, phosphorus, potassium, ferrum etc., these
Nutrient has good facilitation to growth promoter.Fructus Fragariae Ananssae selenium-rich has two kinds of approach: Soil accumulation and fertilizer
Supplement.But China's most area lacks selenium or lean selenium, therefore, just becomes for Fructus Fragariae Ananssae Selenium Supplement from fertilizer
Inevitable approach.Utilize the feature that Fructus Fragariae Ananssae is the strongest to the absorbability of selenium when leaf stretching period and full-bloom stage, for it
Selenium Supplement element.Meanwhile, selenium element is distributed at most in seed, and the seed of Fructus Fragariae Ananssae is distributed in fruit surface,
Can be absorbed by the body and utilize part more.
