Test examples
In Tang hometown of Tuning city ship in Sichuan province, with 105 ° 31 'east, 30 ° 37' north latitude and 286 m altitude, angelica dahurica (Angelica Dahurica) of Umbelliferae is selected(Fisch. Ex Hoffm.) Benth. Et hook.f.var. Fortmosana (Boiss.) Shan et Yuan) as test material, sown at 2021 and 9 months. Adopting random block design, totally setting 10 blocks, each cell occupying 8m 2 Planting is carried out according to the row spacing of 30cm and the plant spacing of 12 cm.
Wherein blocks 1 to 6 were treated with the plant growth regulators prepared in examples 1 to 6, blocks 7 to 9 were treated with the plant growth regulators prepared in comparative examples 1 to 3, and block 10 was set as a blank Control (CK) without any plant growth regulator. According to 125mL/m 2 The dosage of the radix angelicae is 1 time of foliage spraying in the first 1 month of the seedling stage of the radix angelicae.
In the test, the bolting rate of each cell was investigated on the 90 th day after the dahurian angelica root seedlings were sprayed with the plant growth regulator, and the results are shown in table 1. As can be seen from table 1, the early bolting rate of the blank control group is 53.0%, the examples 1 to 6 are all significantly lower than that of the blank control group, and especially the early bolting rate of the angelica dahurica in example 5 is reduced by 56.6% compared with that of the blank control group; the early bolting rate of the angelica dahurica in the comparative examples 1-3 is obviously higher than that of the blank control group, wherein the bolting rates of the comparative examples 1-3 are respectively improved by 5.8%, 26.41% and 6.98%. The plant growth regulator provided by the embodiments 1 to 6 of the invention can obviously inhibit the early bolting of the angelica dahurica.
TABLE 1 early bolting rate of radix Angelicae Dahuricae treated differently
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
