Description

A kind of special selenium-rich conditioner in salt-soda soil and preparation method thereof
Technical field
The present invention relates to agricultural agent fields, specifically, are related to a kind of special selenium-rich conditioner in salt-soda soil and its preparation Method.
Background technology
Fertilizer plays indispensable effect for the production of agricultural, while substantial amounts of fertilizer simultaneously also causes environment Serious influence, utilization rate of fertilizer is low, Fertilizer nutrient is with specific unbalance and the release variant waste and dirt for causing fertilizer of frequency Dye, not only causes to directly affect, with the effect of current, be lost in lake to planting site soil, and the influence to water body is also very Fearful, but also foliar fertilizer has been to be concerned by more and more people, liquid fertilizer can directly act on the blade of crop, stem etc. for this Position is absorbed by the stomata of blade surface, is directly utilized, and is avoided by the active of long-time and long range after root absorption Conveying, foliar fertilizer have the characteristics that utilization rate is high, fast, effect is good and waste is few, environmental protection using absorbing.
Can prevent the fixation of nutrient in the soil using foliar fertilizer, also there is no the effects that soil denitrification, leaching loss and Loss reduces validity and utilization rate, but the mode that blade absorbs foliar fertilizer is similar to root system, mainly passes through blade table The stomata in face enters mesophyll cell after absorbing, then the cuticula and cellulose wall of blade face epidermis are penetrated by free diffusing effect, The speed of absorption seems slightly slow compared with liquid level fertilizer in the rate of drying of blade surface, and the Nutrient Absorption speed of general fruit tree exists Generally in 1-12h when reaching 50%, and greengrocery crop takes several days sometimes, however the outermost epidermal tissue's wax of blade, tool There is the effect of hydrophobic, be unfavorable for the attachment of foliar fertilizer, in addition the surface tension effects of liquid fertilizer cause to be difficult to by subtle Stoma of Leaves, therefore it is critical for how improving adsorption effect of the foliar fertilizer on blade face and reducing the surface tension of foliar fertilizer Problem.
