Description

Miniature water planting leaf vegetables nutrient solution prescription and compound method
Technical field: the present invention relates to a kind of soilless cultivation plant nutrient solution prescription and compound method, particularly a kind of miniature water planting leaf vegetables nutrient solution prescription and compound method.
Background technology: at present both at home and abroad, a lot of scholars are devoted to the research of soilless culture, use nutrient solution to carry out aspects such as vegetable soilless culture, flowers, medicinal herbs merely, and the example of success is also arranged both at home and abroad.But great majority all are devoted to large-scale cultivation and are used, and the research aspect the miniature water planting of family is less.In extensive water planting was produced, the management of nutrient solution was by behind the content of measuring nutritive element in the nutrient solution, uses the chemotrophy material to be replenished item by item for the element of deficiency, realizes cultivation for a long time.Miniature water planting is by adding mother liquor and water, electrical conductivity (EC) value of water planting liquid is adjusted to standard value, realizing the purpose of cultivating.Extensive cultivation and small-scale cultivation have a lot of differences: miniature cultivation generally is indoor, a little less than the light; When using the artificial light source floor light, because the optical band deficiency of light source, when making plant be different from large-scale cultivation to the absorption of some nutritive element under natural lighting the absorbing rule of cultivated plant, vegetables can slow down to the absorption of nutritive elements such as Mg, N, P under low light condition.Thereby be applicable to the nutrient solution prescription of large-scale cultivation, be difficult to satisfactory under the environment when miniature cultivation.The people who is devoted at present miniature mill water culture nutrient solution formulating both at home and abroad seldom, the unit that specializes in technical research such as family water planting vegetables, flowers and medicinal material is also less.
Summary of the invention: the technical issues that need to address of the present invention are: need not to measure the content of nutritive element, can adjust nutrient solution EC value to standard value by adding mother liquor, a kind of miniature water planting leaf vegetables nutrient solution prescription and compound method are provided.
Technical scheme of the present invention is: miniature water planting leaf vegetables nutrient solution prescription is characterized in that the concentrating of nutrients scope is as follows in the nutrient solution: (mg/L of unit)
NO 3-N：70-150mg/L
P： 5-40mg/L
Ca： 80-140mg/L

Mg： 40-60mg/L
Fe： 2.0-6.0mg/L
Mn： 0.4-1.0mg/L
Cu： 0.01-0.1mg/L
All the other are moisture.
Adoptable inorganic fertilizer of preparation nutrient solution and the element that provides are:
The element that the fertilizer title provides
Four water-calcium nitrate NO 3-N Ca
Potassium nitrate NO 3-N K
Ammonium nitrate NH 4-N NO 3-N
Potassium dihydrogen phosphate K P
Dipotassium hydrogen phosphate K P
Potassium sulphate K S
Epsom salt Mg S
EDTA-2NaFe Fe
H 3BO 3 B
MnSO 4-H 2O Mn S
ZnSO 4-7H 2O Zn S
CuSO 4-5H 2O Cu S
(NH 4) 6Mo 7O 24-4H 2O Mo
During preparation, the salt of calcic and iron can be dissolved in water and be mixed with A liquid, all the other compound dissolutions are made B liquid in water.A and B are 100-500 times of concentrate.The volume of the nutrient solution that should prepare as required during use and the cycles of concentration of mother liquor, preparation earlier accounts for the water of the 60-80% of cumulative volume, the A liquid of measuring respective volume then adds in the entry and mixes, slowly add and the isopyknic B liquid of A liquid phase again, and stir while adding, use through the fixed molten nutrient solution that just can be used as after mixing.The nutrient solution of a dosage is the nutrient solution of normal concentration, and EC value (electrical conductivity) is 1.5-2.0ms/cm, and pH value (acid-base value) is 6.0-6.5.
The invention has the beneficial effects as follows: 1, balanced in nutrition, can use continuously by replenishing, compensation process is easy.For example when the cultivation romaine lettuce, can repeatedly carry out the additional adjustment of nutrient solution, the unbalanced phenomenon of nutrient solution can not occur according to the nutrient solution EC value that records.For the water planting planting technology enters urban households, solved a technology barrier.2, under low light condition, cultivate, generally want artificial light filling.Now common light is more with ruddiness and blue light mostly, and a variety of leaf vegetables particularly romaine lettuce can reduce absorption in this case to Ca, Mg, increase absorption to K, P, N, the problem of nutrient imbalance can appear in the short time.Can under the artificial light source blue, that ruddiness is on the high side,, can grow 120-200 days with this prescription by constantly replenishing of nutrient solution.And do contrast with the prescription of use of large-scale production, the cultivation romaine lettuce was only kept 80 days, trophic disturbance will occur.3, the present invention compares with nutrient solution with common large-scale production, under certain low light environment or artificial supplementation illumination condition, still can make each nutrient component in the leaf vegetables maintenance balance absorption nutrient solution.Water planting romaine lettuce in 30 liters of containers for example can be according to the EC value numerical value that records, and adds to the EC value of standard with mother liquor, reaches the purpose of extra-nutrition.Use this prescription, can replenish five times nutrient solution successively, time duration reaches 200 days, during romaine lettuce can plant 4-5 and criticize, and keep good good growth conditions always.And the prescription that the large-scale production of contrast is used balance phenomenon will occur after replenishing three mother liquors.The present invention is multiple authentication in miniature water planting leaf vegetables, well-growns such as romaine lettuce, spinach, and use is simple, convenient, and nutrient solution can utilize the long period.
Embodiment:
