Test examples
In the area of Tang hometown, 105℃in east longitude and 105℃in mountain area of Suusing, 30℃in North latitude and 286℃in elevation, a plant of Hangzhou angelica (Angelica dahurica (Fisch. Ex Hoffm.) in Umbelliferae) was selected as a test material and sown in 2021, 9 months. 10 blocks are arranged in total by adopting a random block design, and each cell occupies 8m of land 2 Planting is carried out according to row spacing of 30cm and plant spacing of 12 cm.
Wherein granules 1 to 6 were treated with the plant growth regulators prepared in examples 1 to 6, respectively, granules 7 to 9 were treated with the plant growth regulators prepared in comparative examples 1 to 3, and granules 10 were set as a blank control group (CK) without using any plant growth regulator. According to 125mL/m 2 Is sprayed on leaf surfaces of the angelica dahurica for 1 time in the last ten days of 1 month in the seedling stage of the angelica dahurica.
