Embodiment 1
[0026] The special synergistic composition for axillary bud inhibitors provided in this example uses the whole plant of Astragalus membranaceus (including stems, leaves and roots) as raw materials to prepare the extract of Astragalus membranaceus.
[0027] (1) Preparation Method 1 of Astragalus membranaceus extract (methanol extract of Astragalus membranaceus)
[0028] Weigh 100g of the dried and crushed whole plant of Astragalus membranaceus and place it in a 5L extraction kettle, add 2.5 kg of methanol, extract under reflux for 2-3 hours, concentrate under reduced pressure to remove the solvent to obtain the extract of Astragalus membranaceus.
[0029] (2) Preparation Method 2 of Radix Astragali Extract (Supercritical Carbon Dioxide Extract of Radix Astragali)
[0030] Weigh 100g of the dried and crushed whole plant of Astragalus membranaceus and place it in an extraction kettle, adjust the pressure to 15-30MPa, the temperature at 40-60°C, and the time for 2-6h. After the e...
Embodiment 2
[0034]This example provides a field test of the inhibitory effect of a special synergistic composition for axillary bud inhibitors containing uniconazole on tobacco axillary buds. The effective components of the composition are flumethamine, uniconazole, azone and supercritical carbon dioxide extract of astragalus rhizome.
[0035] The tobacco variety to be tested is "K326". The test site is Tianjia high-quality tobacco planting base in Xintian County, Yongzhou City, Hunan Province. The soil is a yellow mud field with loose texture, medium fertility, open terrain, and convenient drainage and irrigation.
[0036] Experimental settings Test group 1, test group 2, control group 1, control group 2, control group 3, control group 4 and blank control group. In test group 1, flumethamine, uniconazole, azone, and supercritical carbon dioxide extract of Astragalus membranaceus were compounded into a mixed treatment agent according to the ratio described in Table 1; The ratio described...
Embodiment 3
[0045] This example provides a field test of the effect of a special synergistic composition for axillary bud inhibitors containing uniconazole on cotton topping. The effective components of the composition are flumethamine, uniconazole, azone and supercritical carbon dioxide extract of astragalus rhizome.
[0046] The cotton variety to be tested is "Xinluzhong 37". The test site is in the southern Xinjiang cotton group, and the field management level is the same as that of the middle and high-yield management in the field.
[0047] Experimental settings Test group 1, test group 2 and control group 1, control group 2, control group 3, control group 4 and control group 5. In test group 1, flumethamine, uniconazole, azone, and supercritical carbon dioxide extract of Astragalus membranaceus were compounded into a mixed treatment agent according to the ratio described in Table 2; The proportion described in 2 is compounded as a mixed treatment agent; control group 1 is artificial...
