There are many farming operations involved in grape planting, such as flowering and earing, water and fertilizer management, swelling treatment, etc. Of course, consumers are paying more and more attention to the value of the color, so it is better to plant methods in the planting process. Eat, still look good grapes. And this requires a technology - bagging.
It is necessary to carry out the fruit thinning before bagging. If the fruit pieces are too tight, it is easy to cause cracks. There are many friends who have lost too much grain, and the fruit pieces are crushed and ruptured, and the liquid overflows. After a long time, it causes gray mold, white rot, acid rot and other diseases.
If the weather is too dry before bagging, water the whole garden before the fruit thinning to prevent sunburn. A few leaves can be placed on the top and around the fruit to prevent sunburn. When thinning the fruit, the small particles on the ear should be removed, and the damaged fruit should be removed.
There are many types of bags and there are many varieties. How to choose the right bag to bag, there is also a way.
Green varieties such as Sunshine Rose can be used in colored bags; there are also some red varieties that need to be refracted, and transparent bags are preferred.
When spraying and sterilizing, you should not choose the products of emulsifiable concentrates and powders. Try to choose suspending agents, water-dispersible granules, water emulsions, etc., so as to reduce the damage to grape Fruit powder.
The liquid medicine is mixed evenly and then the medicine is sprayed. After the medicine is finished, the liquid can not be formed on the fruit surface. Try to shake the ear or wire and shake the liquid on the ear to avoid the formation of spots and contaminate the fruit.
When bagging, avoid the hot weather or the weather that suddenly clears after the rain, and wait until the fruit adapts to such an environment before bagging. Also pay attention to the situation of the day, the morning and afternoon low temperature period is the best bagging time.

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.
