CN102550193A - Soil inside source selenium regulation and control technology for producing selenium-rich tea - Google Patents

Abstract

The invention relates to a soil inside source selenium regulation and control technology for producing selenium-rich tea, and the technology can be used for realizing that the selenium-rich tea is produced on the strong-acidic soil of a tea garden in a selenium-rich region under the condition that no people replenish outside source selenium to the tea garden. During fertilizer application management of the tea garden, an alkali improved material is applied in a trenched water drip at one side of a tea ridge, and a biological organic fertilizer is applied to a trenched water drip at the other side of the tea ridge. The alkali improved material is applied to the acidic soil of the tea garden to ensure that the content of effective selenium in the soil is gradually increased, and the biological organic fertilizer is applied to ensure that the capacity of absorbing selenium elements from the soil by tea trees can be improved.

Description

Produce the endogenous selenium control technique of soil of rich selenium tea

Technical field

The present invention relates to the endogenous selenium control technique of a kind of soil, relate to a kind ofly to the high selenium soil of highly acid specifically, improve the technology that selenium element validity and tea tree are produced rich selenium tea in the soil to the absorbing capacity of selenium through regulation measure.

Background technology

At present, the main method of the rich selenium tea of known production be low selenium area through artificial supplemented with exogenous selenium, like the certain density inorganic selenium aqueous solution of foliage spray or execute selenium fertilizer outward, through the biotransformation of tea tree self, the raising of realization tealeaves organic selenium content; But said method exists the problem of safely use amount and safe spray concentration, in case measure is unreasonable, will bring a series of problems such as serious environmental potential safety hazard, and can not improve effective utilization of contained selenium in the soil own.And after the soil severe acidification in high selenium area, can bring serious restrictive function again to the production of rich selenium tea, utilize the endogenous selenium control technique of soil still to rarely have report with the rich selenium tea production that realizes high selenium area strongly acidic soil.

Summary of the invention

In case it is unreasonable in order to overcome existing rich selenium tea production technology measure; To bring the serious environmental potential safety hazard; With the deficiency that can not improve effective utilization of own contained selenium in the soil; And at the technological gap that utilizes the endogenous selenium control technique of soil to produce with the rich selenium tea of realizing high selenium area strongly acidic soil; Patent of the present invention provides a kind of endogenous selenium control technique of soil of producing rich selenium tea, and this technology can be directed against the high selenium soil of highly acid, through selenium element validity and tea tree in the regulation measure raising soil absorbing capacity of selenium is produced rich selenium tea.

The technical scheme that patent of the present invention is taked is: in the fertilizing management of tea place, one side drip trench digging applies alkalescence improvement material on the tea ridge, the opposite side drip trench digging biological organic fertilizer that applies on the tea ridge.Because effective selenium of soil and soil pH value are extremely significantly positive correlation, apply the pH that alkalescence improvement material can improve soil gradually in the acid tea garden soil, the effective Se content of soil is increased gradually; And biological organic fertilizer can strengthen the tea root vigor, and tea garden soil applies biological organic fertilizer can improve tea tree absorbs the selenium element from soil ability, finally reaches the target that improves the tealeaves Se content.

The beneficial effect of patent of the present invention is not have artificially to realizing producing rich selenium tea on the strongly acidic soil of high selenium area under the situation of tea place supplemented with exogenous selenium.

Embodiment

Embodiment: in the fertilizing management of high selenium area highly acid tea garden soil, one side drip trench digging applies alkalescence improvement material on the tea ridge, and opposite side drip trench digging applies biological organic fertilizer on the tea ridge.

Claims (1)

1. endogenous selenium control technique of soil of producing rich selenium tea is characterized in that: one side drip trench digging in tea ridge applies alkalescence improvement material, and opposite side drip trench digging applies biological organic fertilizer on the tea ridge.
