s3: and (5) mixing the fermented mixture of caragana microphylla branches and caragana microphylla leaves processed in the step S1 with the granular caragana microphylla roots processed in the step S2, crushing and drying.
The caragana microphylla tender branches and leaves contain nitrogen, and are good raw materials for preparing green manure by retting, the caragana microphylla roots have root nodules and have a soil fertility, and after the caragana microphylla is treated by the method, the root nodules of the caragana microphylla roots are kept, and meanwhile the fertility of the caragana microphylla can be fully exerted.
The embodiment also provides a nutrient solution matched with the renewable nutrient medium for the miniature potted Chinese rose, which comprises the following nutrient elements in content: 1E1.5mmol/L NH4 +,1.2~6.5mmol/L K,1.2~3.75mmol/L Ca,0.45~0.75mmol/L Mg,4.95~10.75mmol/L NO3 -,0.35~1.75mmol/L SO4 2+,0.35~1.5mmol/L H2PO4 -(ii) a Also comprises the following trace elements: 15mmol/L Fe, 5mmol/L Mn, 3mmol/L Zn, 10mmol/L B, 0.5mmol/L Cu, 0.5mmol/L Mo.
The present example was configured with the following three specific nutrient solutions:
(1)1mmol/L NH4 +,6.5mmol/L K,2.5mmol/L Ca,0.75mmol/L Mg,9mmol/L NO3 -,1.75mmol/L SO4 2+,1.5mmol/L H2PO4 -(ii) a Also comprises the following trace elements: 15mmol/L Fe, 5mmol/L Mn, 3mmol/L Zn, 10mmol/L B, 0.5mmol/L Cu, 0.5mmol/L Mo;

In order to obtain the substrate and the nutrient solution, the inventor bought a commercially available miniature potted rose culture substrate CK3 as a control, and prepared experimental substrates with the following component proportions respectively, as shown in Table 1:
TABLE 1 base ingredients and compounding ratios
Figure GDA0003155295780000041
Figure GDA0003155295780000051
The water loss of the matrix is studied through experiments, the experimental result is shown in figure 1, and the result shows that the water loss of CK2, T1, T2, T3, T8 and T9 is obviously higher than that of other combinations, wherein T8 and T9 are obviously lower than that of T2 and T3. The reason for the analysis may be that coconut coir loses water more easily than turf, but the water retention effect is improved after vermiculite is added.
In addition, plants are cultivated by using the different substrates, the PH value and the EC value of the survival plants are shown in figures 2 and 3, and the optimum growth pH value of the miniature Chinese rose is 5.5-6.0, the EC value is 1.2-1.8, and the pH value and the EC value of the 13 substrates are both suitable for the growth of the miniature potted Chinese rose.
The experimental results of the plant height and the leaf number of the plants after the cuttage for 32 days are respectively shown in the attached figures 4 and 5, and the results show that in terms of plant height, CK2, T7, T8 and T9 are short, the leaf numbers CK2, T7, T8 and T9 are minimum, and the plant height is positively correlated with the height. The relatively dark green leaves of T10 and good growth of overground parts are primarily thought to be due to the fact that some components contained in caragana microphylla can promote plant growth.
Comprehensively evaluating each index, wherein the matrix T2, the matrix T6 and the matrix T10 are all superior to a control matrix CK1 and a matrix CK3 commonly used by potted roses at present; from the composition of the matrix, the dosage of the turf is reduced by 41% and 50% respectively by the matrix T2 and the matrix T6, and the matrix T10 uses Ningxia wild plant caragana microphylla waste as the matrix to be applied to the potted matrix for the first time, so that the turf is partially replaced. Through comparing the market cost of each component, the cost of the substituted substrate of the embodiment is reduced by 28-97%.
The inventors prepared nutrient solutions with different concentrations, and the prepared nutrient elements and the used trace elements are respectively shown in tables 2 and 3:
TABLE 2 nutrient elements in the nutrient solution
