A kind of stereo circulating the invention discloses selenium-rich leaf vegetables flows cultural method, the present invention can not only shorten the growth cycle of leaf vegetables, nitrate content be reduced, without toxic heavy metal element, and leaf vegetables yield, quality and Se content can also be improved, and make vegetables that there is healthcare function.Using stereo circulating type of flow culture leaf vegetables, space is made full use of, improves moisture and nutrientuse efficiency.Toxic heavy metal element is free of in nutrient solution, the no disease and pests harm phenomenon during leaf vegetables is produced, the vegetables produced are without toxic heavy metal element and pesticide residue.Largely and in addition to micronutrient element, also containing human essential elements selenium, vegetables Se content can be effectively improved necessary to containing plant in nutrient solution.For the present invention in addition to mother liquor is supplemented to fluid infusion groove and is transplanted seedlings and belongs to manual operation, remaining is automation mechanized operation.In addition, adding the nutrient solution of different pH value and ion concentration into backflash by timing, reach the effect of automatic adjustment nutrient solution pH value and ion concentration.
Description
Technical field
The present invention relates to the stereo circulating flowing culture side of a kind of vegetables cultural method, more particularly to a kind of selenium-rich leaf vegetables
Method.
Background technology
At present, leaf vegetables on the market is essentially from Production of Large Fields.Due to leaf vegetables yield and the profit of coveting, production
Upper generally existing largely applies the phenomenon of nitrate fertilizer, so as to cause Nitrate higher.In addition, some agricultural land soils
Polluted with irrigation water by harmful heavy metal, can so cause to contain a certain amount of toxic heavy metal element in vegetables.Long-term food
Serious harm can be brought to health with this leaf vegetables.Selenium be humans and animals necessary to trace element, have it is anti-oxidant, carry
High immunity, pre- anti-cancer, anti-aging, the maintenance effect such as thyroid gland and male fertility.Se content in leaf vegetables is improved, is had
Beneficial to the general level of the health for improving human body.
China's leaf vegetables cultivated area is very big, and leaf vegetables production becomes the pillar industry increased farmers' income.Due to China's soil
Se content is generally relatively low in earth, therefore the selenium in leaf vegetables is difficult to meet the needs of health.Although take soil spraying selenium or leaf
The measures such as face spray selenium can produce selenium-rich leaf vegetables, but the biological effectiveness of selenium can be substantially reduced by applying selenium in the soil, and waste has
The selenium resource of limit.Foliar application of selenium easily by such environmental effects, such as runs into continuous rainfall or strong wind weather, operation difficulty in the phase of spraying
Greatly, it is poor to spray selenium effect.Low and without harmful heavy metal the vegetables of nitrate content can be not only produced using water planting mode, and
And it is readily available selenium-rich leaf vegetables.
The content of the invention
The purpose of the present invention is that to solve the above-mentioned problems and provides a kind of stereo circulating flowing training of selenium-rich leaf vegetables
The method of supporting.
The present invention is achieved through the following technical solutions above-mentioned purpose：
The present invention uses stereo circulating culture apparatus culture selenium-rich leaf vegetables, and the stereo circulating flowing culture apparatus includes mending
Liquid bath, backflash, nutrition liquid bath, water planting groove, water pump, filter hole, ultraviolet sterilizing lamp, conductivity measuring instrument, pH meter, activity
Lid, cultivation board, woven hose, return duct, timing fluid infusion hole and cultivation hole, fluid infusion groove, backflash and nutrition liquid bath are to be vertically connected with,
4-5 time switch is installed between fluid infusion groove and backflash, periodically can convey mother liquor, backflash and nutrition liquid bath to backflash
Between be 4-5 filter screen, the nutrient solution of reflux can be filled into nutrition liquid bath, have removable cover above fluid infusion groove, be used for
Mother liquor manually is added, backflash top is provided with 4-6 15W ultraviolet sterilizations, for timing sterilization, pH is provided with left side wall
Meter and conductivity measuring instrument, for detecting storing liquid intermediate ion concentration and pH value in due course, are provided with timing water in nutrition liquid bath
Nutrient input, can periodically be sent in the water planting groove of highest point, be provided with return duct at the 2/3 of each water planting groove, work as liquid by pump
When face is higher by 2/3 liquid level, nutrient solution can be automatically flowed into following nutrition groove by return duct, until being back in backflash,
Fluid infusion groove and nutrient solution sump volume are suitable, are the half of sump volume of flowing back, have cultivation board above water planting groove, equipped with culture hole,
Culture bore dia is set to 2.5-5.0cm according to culturing vegetable species, is that 10-25cm sets culture hole position according to strain, line-spacing
Put, water planting groove both sides are far from punching placed in the middle at the 5.0cm of top；
Cultural method comprises the following steps：
Step 1: select have no mechanical damage, disease-free leaf vegetables seed, with 2% hypochlorite disinfectant 15 minutes, repeatedly
It is immersed in after cleaning in distilled water, when vernalization 24 is small under the conditions of being placed in 25-30 DEG C；
Step 2: leaf vegetables seed is equably sown in the fine sand cleaned in plastic tub, the long 32cm of plastic tub, width
24.5cm, high 10cm, covering fine sand 0.5cm is thick, and a small amount of water is sprayed with watering can, fine sand is kept moisture state, finally with fresh-keeping
Above film plastic covering basin, interval 8cm opens the hole of diameter 2cm on preservative film；
Step 3: when 24 is small, spray 1/2 concentration nutrient solution once with watering can, fine sand is kept moisture state, seedling
Cultivate in fine sand and transplant seedlings after three weeks；
Step 4: the consistent leaf vegetables seedling of growing way is selected, the sponge wrapping basal part of stem with thickness for 2.0-3.0cm, then
Be implanted in strain, line-spacing is in the culture hole on the cultivation board of 25cm, cultivation board is placed in above culture box, and leaf vegetables root is totally submerged
In nutrient solution, nutrient solution be contained in long 70cm, width 45cm, high 15cm specifications plastic tub in, nutrient solution injecting height for modeling
Feed basin it is high 4/5 at, i.e., less than top 3.0cm；
Step 5: after transplanting seedlings, leaf vegetables is using standard liquid nutrient flowing culture, and nutrient solution circulates once when 4 is small；
Step 6: sterilized once to nutrient solution with ultraviolet sterilization lamp when 4 is small, 30 minutes every time；
Step 7: culture harvests after 6-8 weeks, it is selenium-rich leaf vegetables.
Specifically, the nutrient solution in the step 4 is by weight containing Ca (NO in every liter of nutrient solution3)2·4H2O is
0.24g, (NH4)2SO4For 0.13g, K2SO4For 0.32g, KH2PO4·2H2O is 0.05g, NH4H2PO4For 0.023g, MgSO4·
