Abstract
The invention discloses a method for applying selenium to selenium-rich oil sunflowers in saline-alkali soil and belongs to the technical field of crop planting. The method comprises the following steps: a) applying a nitrogen phosphorus potassium base fertilizer to the soil for sowing; b) applying the first selenium fertilizer to soil: spraying a sodium selenate solution to the soil for sowing, plowing and uniformly mixing, wherein the dosage of the sodium selenate is 20g per mu; c) sowing; d) applying the second selenium fertilizer to leaves: preparing sodium selenite into a sodium selenite solution and spraying the sodium selenite solution to the front side and rear side of each organ of an oil sunflower plant in a flowering phase of the oil sunflower; and e) repeating the step d) after the step d) is finished for 6 to 7 days. According to the invention, a two-year field test proves that the content of the elements, such as selenium, in the oil sunflower seeds and the nutrition of the oil sunflower seeds are effectively and economically increased according to the method of combining soil application of selenium fertilizer with foliage spray of selenium fertilizer, the inorganic selenium is directly converted into organic selenium, the method is safe and simple and the selenium content is increased to 9.73mg.kg<-1>.
Description
Technical field
The present invention relates to crop-planting technical field, and in particular to a kind of salt-soda soil selenium-rich oil sunflower applies selenium side
Method.
Background technology
Shanxi Province is that national Kaschin-Beck disease retransmits area, and the whole province's number of patients is distributed in 30 Yu Ge counties up to people more than 4.5 ten thousand.Its
In, Yuncheng Prefecture's category retransmits area, and Selenium in Soil contents level is low, and only 0.12-0.29mg/kg, average 0.18mg/kg belong to scarce selenium
Level.And cause the basic reason of Kaschin-Beck disease to be the low selenium of soil, cause the content of local drinking water and Selenium In Foods low.Lack
Selenium declines can also human body and Immune Function In Animals, cause the kind more than 40 such as cardiovascular and cerebrovascular disease, diabetes, enterogastritis, Keshan disease
The generation of disease.Selenium element lacks has become national important nutrition problem, seriously threatens the healthy of people.
Therefore, how safely and effectively to improve Di Xi areas human body selenium level has become medical science, the focus of agronomic periodicals.But by
Accommodation between people and general animal lack and be poisoned to organism selemium nutrition is very narrow, and is not easy to accomplish people from various places
Periodically steadily supplement trace nutrition permanent with livestock and poultry, so being exactly that crop is applied selenium and carries in the safest benefit selenium method in low selenium area
High its selenium content cultivates collection selenium crop varieties, and selenium element content can effectively improve human body Se nourishment level in reinforcing crops.
Yuncheng, Shanxi Soils In The Region degree of salinity is quite serious.Oily certain herbaceous plants with big flowers is that the Main Economic of Shanxi salt-soda soil cultivation is made
Thing.Both can develop saline land, but energy biological treating is saline land, reaches exploitation selenium-rich oil certain herbaceous plants with big flowers, improvement salt-soda soil and improves salt-soda soil and gives birth to
Produce potentiality important in inhibiting.Therefore, the present invention have studied Shanxi Kaschin-Beck disease and retransmit with salt-tolerant plant oil certain herbaceous plants with big flowers as planting material
