1. Choose a land with loose soil, fertile soil and good drainage. Selecting good varieties and spraying new high-fat membrane soil surface can protect the water-proof evaporation, sun-proof and drought-resistant, heat-preserving and anti-freezing, anti-soil layering, suffocation and isolation of pests and diseases, and improve the mother's germination rate.
2. Management of rooting and slow seedling stage. The rooting stage of seedlings is formed from new roots to roots after planting. After transplanting seedlings, spraying new high-fat film can effectively prevent the water from evaporating on the ground and the moisture of the seedlings is not transpiration. Insult pests and diseases, shorten the slow seedling period, and take advantage of the roots to survive and grow healthily.
3, branch and potato management, stem and leaf growth accelerated, roots continue to form expansion should strengthen water and fertilizer management, cultivating and weeding, spraying new high-fat membrane, greatly improve the utilization of effective components of fertilizer, not afraid of solar evaporation, can adjust The amount of water absorbed, drought and rain.
4, the management of the long and deep roots of the stems and leaves, from the first half of July to the end of August this period, the stems and leaves of the stems are swollen, the leaf area coefficient reaches the maximum in this period, spraying the fruit of the fruit to make the underground fruit The nutrient transport conduit becomes thicker, which enhances the fruit's swelling and vitality, the fruit surface is smooth, the fruit shape is strong, the quality is high and the yield is high, and the leaves and leaves are effectively prevented.

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.
