2 results and analysis
Influence of the different calcium substances of 2.1 additions to iris matrix EC
The conductivity of matrix can be shown that content has ionized the solution concentration of salt, can reflect carried in matrix it is solvable
The number of property salinity.Soluble organic fraction in matrix is added essentially from artificial, mainly the quilt by way of root system of plant absorption
Plant accumulates, and also has part soluble-salt to be gradually lost in by modes such as moisture overflows.By the result of Fig. 1 it is found that control 1 is being held
In the case of continuous pouring clear water, due to lacking the in due course supplement of soluble-salt, the EC values of matrix persistently reduce, before handling
0.92mS/cm drop to one month after 0.73mS/cm, be finally reached 0.56mS/cm.And in the control of normal management 2, base
The EC values of matter gradually rise, and by the 0.94mS/cm before handling, rise to 1.09 after one month, are finally reached 1.30.And it adds
Six groups of processing of two kinds of calcium substances then with compare 2 and show similar variation tendency, i.e., with the extension of processing time, matrix EC
Value gradually rises, and six groups of processing are gradually increased to final 1.22-1.37mS/cm by the 0.90-0.97mS/cm before handling.Add
CaO initial stages, the soluble organic fraction content of matrix is added to be significantly increased, three groups of processing are increased to by the 0.90-0.94mS/cm before handling
The 1.12-1.24mS/cm measured for the first time after processing, and with the increase of number of processes, EC values persistently increase, the 4th processing
Numerical value is measured afterwards to reach 1.35-1.38mS/cm and tend towards stability.And the CaCO of three concentration gradients3Processing handles phase with CaO
Than the influence to matrix EC is not obvious, little with the EC value variation tendency differences for compareing 2.
Influence of the different calcium substances of 2.2 additions to iris substrate pH
PH value is also an important indicator of matrix chemical property, can reflect basal conditions, the conversion of stroma ground substance composition
Trend and mass exchange dynamic equilibrium.As shown in Figure 2, addition external source calcium substance changes matrix to a certain extent
PH value.In the case where only pouring clear water, the trend continuously decreased is presented in the pH value of matrix, is down to by 4.76 before handling
4.57.And in the case of normal fertilizer and water management, the downward trend of pH value becomes apparent, and 4.81 by drop to final
4.46.This illustrates matrix in use, can show the sign being gradually acidified over time, and lasting rich water
Supply can then aggravate the generation of this case.And add that external source is calcareous, the acidification of matrix is slowed down to a certain extent, especially
It is that CaO treatment effects become apparent.CaO is applied after dissolving 600 times, and the pH value of matrix can be made to be gradually risen to 4.91 by 4.74,
CaO is applied after dissolving 400 times, and the pH value of matrix can be made to rise to 4.90 by 4.77, and 200 times of CaO dissolvings can then make substrate pH
Value rises to 4.88 by 4.76.And apply CaCO3Influence afterwards to matrix pH value is not very notable, and the pH numerical value of each group matrix goes out
The trend now continuously decreased, but compared with the control group, CaCO3The pH of processing each group increases.
3 conclusions
Sphagna is bryophyte, has stronger water storage, fertilizer conservation and venting capability.Its excellent physicochemical property substantially may be used
To meet the requirement of the growth and development of plant.For a long time, sphagna is extensive as the important cultivation matrix of the flowers such as iris
Using.Only, sphagna itself can decompose release NH in the case of long-term use4 +- N is accumulated a large amount of after root system absorption replacement
H+, easily lead to corruption, acidification.And in acidic environment, the elements such as silicon, calcium, magnesium lack, and phosphorus element is easily fixed by iron, aluminium etc..
Meanwhile the excessively high Probability that also will increase root rot of EC values.In this experiment, external source calcium substance is added into sphagna matrix to base
The influence of matter EC values is little, and wherein EC values changing rule is consistent substantially with normal fertilizer and water management, and reason may exist with CaO
Solubility is relatively low (solubility is 0.156g at 20 DEG C) in water, CaCO3It is related to be substantially insoluble in water.The solubility salt of high concentration
It is likely to form reverse osmotic pressure, causes plant dead to make root system of plant be damaged.And the addition of external source calcium substance
Do not significantly improve the solubility salt concentration of matrix, it can be seen that, the addition of external source calcium substance is not to iris root system
Growth has an adverse effect.It is and right by this experiment it is found that addition external source calcium substance changes the pH value of matrix to a certain extent
Significant effect is compared in photograph.Especially CaO slows down the acidification of matrix to a certain extent, and treatment effect is more apparent, and applies
CaCO3Influence afterwards to matrix pH value is not very notable.This explanation, CaO ratios CaCO3It is more suitable for adjusting matrix pH value, this conclusion
It is more consistent with other document reports.For the application concentration and ratio of external source calcium substance, this experiment confirms, 200-600 times three
The CaO of a concentration influences significantly the pH value of matrix, and little to the function and effect difference of pH value each other, illustrates 600 times
Processing can reach ideal function and effect.
The present invention is examination material with butterfly orchid variety " big capsicum ", has studied different external source calcium substances to iris cultivation matrix
The influence of sphagna EC, pH value.Result of study shows：EC values are continuously decreased with the extension of time in the case of pouring clear water, by
0.92mS/cm drops to 0.56mS/cm.EC values under the conditions of normal fertilizer and water management are gradually increasing, and are risen to by 0.94mS/cm
1.30mS/cm.And the promotion of matrix EC values can be aggravated by adding CaO, and with the increase of number of processes, EC values persistently increase, the
Numerical value is measured after four processing to reach 1.35-1.38mS/cm and tend towards stability.Add CaCO3Do not have substantially to the EC values of matrix
It influences.With the extension of processing time, the pH value of control group sphagna continuously decreases.Pour clear water in the case of, matrix pH value by
4.76 before processing are down to 4.57.And in the case of normal fertilizer and water management, the downward trend of pH value becomes apparent, by
4.81 drop to final 4.46.But addition external source calcium substance can substantially change sphagna pH value.Wherein, 200-600 times of CaO is to water
The improvement of tongue pH value is more apparent and effect is closer to, and matrix pH value can be made to be improved to 4.88- by 4.74-4.77
4.91, add CaCO3Afterwards, it though the pH value of sphagna decreases, is improved compared with the control.
The above is only the better embodiment to the present invention, not makees limit in any form to the present invention
System, every any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
