Detailed description of the invention
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
The method of low mercury salt-soda soil plantation Suaeda salsa and extraction plant salt in embodiment 1 one kinds
The selection in step 1, salt-soda soil
The growing area salt-soda soil selected: the pH value of soil is 8.7-9.6, basicity 31 ~ 32%, and salt content is 0.5%, and mercury in soils content is 1.2-1.5mg/kg.
Step 2, improvement soil
The previous year that plantation alkali is fluffy, be evenly sprinkled into soil conditioner 170kg/ mu to the plot selected, turn over and rake, water once, soil conditioner can better be played a role.
Described soil conditioner comprises the component of following weight portion: oyster shell whiting 8 parts, natrium citricum 10 parts, nimbin 3 parts, charcoal 4 parts, 7 parts, aluminum sulfate, polyvinyl alcohol 10 parts, 4 parts, diatomite, water-loss reducer 9 parts.
Step 3, plantation Euphorbia esula L and hyssop
(1) soil is arranged
Before plantation, readjustment of field plot is become rule plantation ditch side by side, plantation ditch depth 20-30cm, plantation one, ditch is by one.
(2) plant
Between employing, kind mode plants Euphorbia esula L and hyssop, and a kind ratio is 3:2, namely plants 2 row hyssops between 3 row Euphorbia esula Ls.Planting density is 40cm × 45cm, and described planting density is the plant strain distance × line-spacing of plantation.
(3) apply fertilizer
Every mu with fertilizer: 50kg nitrogen-phosphorus-potassium compound fertilizer, 20kg urea, during fertilising, dissolved by fertilizer in water, Sui Shuichong executes, and monthly applies fertilizer once.
(4) irrigation and draining
Adopt broad irrigation mode to irrigate, within every 20 days, irrigate once, ensure that soil is not arid.During as field internal water accumulation in rainy season, discharge ponding as early as possible, avoid damage or crop failure caused by waterlogging.
(5) manage
Euphorbia esula L grows to Post flowering, carries out defloration, is plucked by flowering parts, altogether defloration 3 times.
Hyssop grows to Post flowering, carries out defloration, altogether defloration 3 times.
Defloration can promote the growth of root system and the absorption of heavy metal.
Step 4, heavy metals measurement.With atomic absorption spectrophotometry, detect the content of heavy metal in soil mercury.
Step 5, plantation Suaeda salsa
After the field plantation Euphorbia esula L selected and hyssop, next year plantation Suaeda salsa, concrete grammar is:
(1) Seed Treatment
ABT root-inducing powder 10-20 part, brassin lactones 0.05 ~ 0.1 part, Thidiazuron 0.7-1 part configuration root-inducing powder, get above-mentioned root-inducing powder 0.7g ~ 1g and first dissolve with a small amount of alcohol, then add 1L water, seed soaking time 1-2h.
(2) plant
Mid-March, by the Suaeda salsa seed that processed in field.
(3) manage
The timely seedling thinning when seedling has 6 true leaves, spacing in the rows 8-10cm, weeds out the rank grass simultaneously, and after thinning, 2 ~ 3d sprays the urea liquid of a time 0.3%, ensures that Suaeda salsa grows vigorously.
(4) irrigate
Namely water after plantation, after Suaeda salsa enters branching stage, judge for moisturizing with 0-30cm soil layer soil moisture content 12%, water in time during lack of water.
(5) gather in the crops
Mid-November, gather in the crops.2 ~ 4d waters once after adopting, and meanwhile, urea 10-20kg/ mu is executed in punching, promotes regeneration branch, capable of circulationly gathers.
Step 6, plant salt extract
(1) dedusting is cleaned
Suaeda salsa to be extracted through being up to the standards being cleaned, drying or drying.
(2) pulverize
The pulverizer putting into built-in 60-80 eye mesh screen through cleaning dedusting Suaeda salsa to be extracted is pulverized.
(3) flood
After Suaeda salsa after pulverizing is put into the mixing of materials tank of built-in agitator, then add distilled water in mixing of materials tank, stir, dip time is 1h, obtains mixing of materials liquid; To add water with the weight ratio of Suaeda salsa be 8 ~ 12: 1, the stir speed (S.S.) of described agitator is 60r/min.
(4) ultrasonic wave process
Described mixing of materials liquid supersonic generator is carried out ultrasonic wave process; The operating frequency of described supersonic generator is 18KHz, and Extracting temperature is 30 DEG C, and ultrasonic treatment time is 1h.
(5) centrifugal
Pour the liquid after ultrasonic wave process into centrifuge, carry out centrifugal, obtain supernatant.
(6) crystallization
Supernatant is heated to 56 DEG C and suction filtration while hot, the solution obtained, under 94.75kpa pressure, is heated to 78 DEG C, stops when evaporative crystallization to weight no longer reduces, obtained finished product plant salt.
