Saline-alkali soil conditioner of the present invention contains effective composition 30%, is brown liquid.
Saline-alkali soil conditioner of the present invention is used to be subjected to the farmland and the new land reclamation of saline and alkaline infringement, by regulating Soil structure and physics and chemistry state salt falls except that alkali, make saline and alkaline influence reduce to minimum level to plant-growth, can improve the infiltration of saltings moisture, make affined moisture and nutrition transfer upstate to and improve seedling rate, promote plant growth and increase output; Action effect to soil is remarkable, and is easy to use, and cost is low; Saltings after handling with saline-alkali soil conditioner by physiology, the biochemical action to plant root and topsoil gong, can guarantee that plant plants in the saltings, the normal germination, and healthy growth, to people, animal safety, harmless to crop, soil.
The scope of application of saline-alkali soil conditioner of the present invention is field crop, protection ground, lawn, careless pasture, saline-alkali wasteland, fruit tree, vegetables and ornamental plant.Be subjected to the mild or moderate soil of saline and alkaline harm, every mu of consumption 500-600 milliliter; Containing saline and alkaline higher newly turning up the soil, every mu of consumption 3-5 kilogram used, and can make soil restoration arrive normal plantation state in continuous 3 years.
Adopt saline-alkali soil conditioner of the present invention soil to be carried out the test of the activation of phosphorus and iron:
For examination soil respectively from Changping, Beijing, Jinghai, Handan, Hebei and Binzhou, Shandong fetch farmland moisture soil soil sample, the basic physicochemical character of these soil sees Table 1.
1, carries out the test of saline-alkali soil conditioner earlier: accurately take by weighing some parts of 2.0g wind desiceted soil,, add saline-alkali soil conditioner solution (the 10umol g of certain volume by 10: 1 soil ratio to the activation of soil phosphorus
-1And 50umolg
-1), be contrast with isopyknic deionized water, repeat 3 times, addend drips toluene, to suppress microbial activities.Constant temperature vibration 1h under the condition of (25 ± 1) ℃, centrifugal 10min under the 30000g filters, and measures phosphorus with molybdenum blue colorimetric method, and Fe measures with the ICP method.
Result and analysis: saline-alkali soil conditioner is to the activation of two class soil phosphoruss; Saline-alkali soil conditioner can obviously promote the release of soil phosphorus; Saline-alkali soil conditioner is closely related to the content of available phosphorus in the activation of soil phosphorus and soil type and the soil.Saline-alkali soil conditioner is remarkable positive correlation to the content of available phosphorus in the activation of soil phosphorus and the soil.As can be seen from Table 2, saline-alkali soil conditioner is in close relations to the activation and the soil type of soil phosphorus.Relatively saline-alkali soil conditioner can find that to the activation of calcareous soil (north) and red soil phosphorus (south) saline-alkali soil conditioner is to the release to birth ratio calcareous soil height of acid soil.This mainly is owing to after adding digestion agent on the two class soil, soil balanced solution PH difference.On calcareous soil, what phosphorus was played activation only is organic anion; And on red soil, negatively charged ion and H+ play activation jointly.Therefore, make saline-alkali soil conditioner be greater than calcareous soil to the release action of red soil phosphorus.Another possible reason is on acid soil, and soil ulmin Fe (AI)-P complex compound proportion will be apparently higher than calcareous soil (on the calcareous soil, phosphorus mainly exists with the Ca-P form), and this a part of phosphorus is easy to be activated.
Table 2 saline-alkali soil conditioner is to soil phosphorus release conditions (umol g under the green multiple health different concns in the release promoter action sampling position of phosphorus in the soil
