In February, when the Yangmei young seedlings were planted in spring, in order to improve the seedling survival rate of Yangmei seedlings, farmers should pay attention to the following technical points: Time for planting: All provinces should be in the months 2-3. After the ice-free period, Yangmei begins to sprout and selects the yin. It is better to plant the sky or rainy days. Planting gardens: Yangmei is shade-tolerant and humid, and the average annual temperature is 15-21°C, and the minimum temperature is -8°C or above. In areas where annual rainfall is not less than 1000 mm, cultivation can be carried out. Yangmeishu is most suitable for cultivation below 500 meters above sea level, with ferns, rhododendrons and other plants on the hills, without standing water, and on wet hillsides. Dig a good planting hole: Before planting, dig a good planting hole (digging should be carried out in the winter to help reduce soil pests and diseases), it is best to dig into a fish scale pit, a depth of 0.8 meters. The topsoil and the soil should be separated so that they can be used in layers when filling. After the planting hole is dug, the basic fertilizer should be applied. Each hole should be applied with 25 kg of manure (or 3 kg of vegetable cake) and 10-15 kg of coke plaster, plus a superphosphate of .55 kg. Mix with the soil when planting. Into. Avoid contact with roots and fertilizers when planting, especially superphosphate. The weeds and trees around the fish scale pit should not be immediately removed. After the seedlings have survived, the tall trees will be cut off. Strong seedlings were selected: Stable, high-quality seedlings with several branches and no roots were selected for colonization. After the seedlings are raised, some yellow mud slurry is applied to the roots of the seedlings, and the root system is then wrapped with a nylon membrane for transport. The maximum time from raising to planting should not exceed 10 days. Colonization method: In order to improve the survival rate of seedlings, it should not be shallow when planting, especially where the autumn drought is heavy. All the old scions on the rootstock should be buried under the soil, and at least 3-5 leaves should be buried in the soil to make the scions root. Before planting, all the leaves should be cut off, leave the petiole, and remove the nylon film on the scion. If there is a root in the cut, apply a pruning shear to cut the wound. At the same time, attention should be paid to the work done by the dry work. The center dry height above the interface should be 25 cm. When planting, first cover a layer of 15-20 cm thick top soil on the fertilizer, which is the soil that is in direct contact with the root. Put down the seedlings, straighten out the roots, fill the topsoil several times, and keep it practical. Cover the top 20-30 cm above the ground. Cover 1-2 times with good soil and cover with loose soil.
Natural extracts are biologically active compounds or mixtures extracted from various plants and animals or microorganisms in nature. These extracts contain a wealth of chemicals, Such as alkaloids, flavonoids, saponins, polysaccharides, volatile oils, collagen, proteins, peptides, enzymes, antibodies, antibiotics, Amino Acids, nucleic acids, enzymes, monosaccharides, oligosaccharides, polysaccharides, glycoproteins, resins, colloids, lignin, vitamins, fats, oils, waxes, alkaloids, volatile oils, flavonoids, glycosides, phenylpropanoids, organic acids, phenols, quinones, steroids And antibiotics, etc. Natural extracts have received attention in several fields due to their wide range of sources and potential multiple uses. They can be used in the pharmaceutical industry as ingredients in medicines or health supplements; In the cosmetic industry, as a functional or active ingredient to improve skin health; In the food industry, as an additive or flavoring agent to increase the nutritional value and taste of food; In addition, they have different applications in the fields of agriculture, environmental protection and scientific research. Extraction methods include solvent extraction method, ultrasonic extraction method, microwave extraction method, enzyme extraction method, supercritical fluid extraction method and microwave assisted extraction method, etc. The choice of which method usually depends on the nature of the substance to be extracted and the target requirements of the final product. With the development of technology, the extraction process is continuously optimized to improve extraction efficiency, reduce environmental impact and maintain the biological activity of the extract.
