In recent years, the economic benefits of planting grapes have been better. However, due to variety factors and temperature, humidity, light, moisture and other adverse factors, grapes are often fruit failure, there is a serious drop, fruit drop phenomenon, so that production decline, quality, lower economic benefits. Therefore, in order to obtain high-quality and high-yield grapes, effective agricultural technology measures should be adopted in flower and fruit management.
Through the comparison of various kinds of flower and fruit regulators used by farmers for many years, “Yunda-whole tree fruit†is an ideal regulator. Its main ingredient is a combination of gibberellin G4+7 and brassinolide modulators. It is a new type of plant growth regulator that replaces the conventional flower-protecting agent gibberellin A3 (90%).
The specific method of use is to spray the "cloud big-full tree fruit" 1500-2000 times 1 or 2 times (focus on the spraying of the ear) in the early flowering period and after the flowering of the vine to significantly increase the fruit setting rate. In the expansion of young fruit, spray “cloud big-full tree fruit†2000 times, reduce the concentration of abscisic acid in the stem parts, prevent the formation of fruit stem dissection, reduce physiological fruit drop, and accelerate fruit enlargement and fruit evenness, promote fruit sugar The synthesis and increase of sugar content, significantly increase production, and the appearance of beautiful, increase the sweetness, the selling price increased significantly.
Plant extraction process
1. Select plants/herbs. No more than ancient prescriptions, prescriptions, folk herbs to find. At present, common and uncommon herbs have been studied. At present, it is mostly to increase the amount of medicinal materials to extract and separate components with low content, or to find medicinal plants that have never been studied from miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. The extraction. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (low polarity → high polarity). Daily medicine decoction effective, water and ethanol and other solvents with large polarity, such as artemisinin boiling ineffective extraction with petroleum ether and other solvents with small polarity. Common medicinal materials water/alcohol/ether to go through, separation and identification of more compounds.
3. The separation. This is the most important work. In the solution extracted from the second step, there are dozens of compounds, usually by column chromatography, which is often referred to as the column flushing. It's a lot of work, it's boring, it's low tech. A master's student might do this every day for two years. The column for separating compounds, as shown below, is as large as 2 meters high and as small as 10 centimeters. Change the solvent condition of mobile phase, change the material of column, different conditions and different separation principles of column repeatedly punching, can be separated from the monomer compound.
