Test example 1 dilution stability test of high-content hard water for Bicao water aqua
3420ppm hard water preparation: 3.04g of anhydrous calcium chloride and 1.39g of magnesium chloride with crystal water are weighed into a volumetric flask of 1000mL, and are dissolved and diluted to the scale mark by distilled water.
The test method comprises the following steps: the aqua-aquatics of examples 1 to 3 and comparative examples 1 to 2 were diluted 200 times with the hard water prepared as described above, and placed at 30 ℃ for 2 hours, and stability was observed, and the results are shown in table 1.
TABLE 1 stability results for aqueous herbal preparations
| Item | Appearance after 2h dilution |
| Example 1 | Uniform, transparent and clear |
| Example 2 | Uniform, transparent and clear |
| Example 3 | Uniform, transparent and clear |
| Comparative example 1 | Non-uniform and floccule precipitation |
| Comparative example 2 | Homogeneous, blue fluorescence |
According to the conclusion in table 1, the water aqua of the above examples 1 to 3 can still maintain good stability after being diluted in high-content hard water, while the water aqua of the above comparative example 1 is unstable after being diluted in high-content hard water, and floccules are separated out; the bispyribac-sodium of comparative example 2 has blue fluorescence after being diluted, which shows that the preparation has slightly poor dispersibility in water and generates substances with small particle size. Therefore, the auxiliary agent prepared by the embodiment of the invention can better stabilize the double-herb water aqua, so that the dilution stability of the double-herb water aqua in hard water is better.
Experimental example 2 efficacy test of Bicao aqua after dilution with distilled water
The test method comprises the following steps: the test selects two weeds of eleusine indica and erigeron breviscapus as test objects, seeds of the eleusine indica and the erigeron breviscapus are respectively sowed in disposable paper cups with the height of 9cm, the soil is covered by 0.5cm after sowing, and the seeds are cultured in a greenhouse according to a conventional method after being pressed and drenched. When the eleusine indica and the erigeron breviscapus are in the 3-leaf stage, the stem and leaf spraying treatment is carried out by using the crawler-type crop spraying agent according to the experimental design and measurement, and only distilled water with the corresponding mass is sprayed in the blank group. The experiment was repeated 3 times. After the test material is treated, the test material is placed in an operation hall, after the liquid medicine is air-dried, the test material is placed in a greenhouse for management according to a conventional method, and after 5 days, the fresh weight control effects of the two grass are measured and calculated.
The aqua regia of examples 1 to 3 and comparative examples 1 to 2 was diluted 200-fold with deionized water at a rate of 400ga.i./hm2The results of the treatment of eleusine indica and erigeron breviscapus are shown in table 2.
Fresh weight control effect calculation mode:
effect of preventing eleusine indica and fleabane on watch 25 days later
As can be seen from Table 2, the dual-herb water aqua of the examples 1 to 3 shows better protection effect on the eleusine indica and the erigeron breviscapus, but the dual-herb water aqua of the comparative examples 1 to 2 has poorer control effect on the eleusine indica and the erigeron breviscapus. Therefore, the auxiliary agent has a good synergistic effect on the double-herb water aqua.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
