The buildings are the dry roots of the parispolyphyllasmithvar. Yunnanensis (france.) hand.-mazz.) or parispolyphyllasmithvar. Chinis (france.) hara. The heavy buildings have a long history of use, and the heavy buildings have been of many kinds since ancient times. There are currently 24 plants in the world, mainly in the tropical and temperate regions of the eurasian continent, 19 in the country, in the north and the south, and more in the south-west provinces. The heavy buildings are of great pharmaceutical value and are widely used in the production of various chinese medicines and clinical products, which are essential traditional medicines in our country. Of the 24 heavy buildings in the world, the highest value and best quality of the pharmacological products are found, mainly in and around yunnan, which is one of the primary plants of the chinese pharmacy. The fifeng building, alias unicorn, is a multi-year herbivorous plant growing under a forest of 1,300-3200 metres above sea level, with a one-year fall in leaf, with a four-july bouquet and an eight-november fruit period. The plum complex is characterized by a pattern of “negative, damp and damp”, a wet, shaded environment, well-growing in a flat, irrigation-friendly, well-drained and fertilized sandy and fertile sandy land with a high level of corruption and organic content. During the growth of the filac complex, higher air moisture and shades are required. The average annual temperature is 10-18°c and the frostfree period is over 200 days. The annual rainfall of 850 to 1,200 mm and the concentration of rainfall in the period from june to september is over 75 per cent wet air, and the soil night tide meets the demand for soil water for the growth and development of the heavy-earth buildings. During the planting of the fir-heavy buildings, the shades are built between 60 per cent and 70 per cent, and dispersing light can be effective in promoting the growth of the fir-heavy buildings。
I. Methodology
(i) seed breeding. It takes two winters, and the rate is low. Most of the seeds in the heavy buildings matured in september and october and were collected to boost the growth of the seeds, as the skin becomes red when the hyena cracks. Wash the harvested fruit away from the fruit, and dry it with a little water, as wet sand or ascubation of the earth. This is done by: the ratio of seeds to sand (earth) is 1:5; 1% of the seed weight of the seed is applied in a polymixable humid powder that is modulated, contained in a seedling frame (bag), placed indoors, with a seed temperature of 18 to 22°c, checked every 10 to 15 days, and a sand moisture of between 30 and 40% (with a sand held in hand and held tight and loosed). In may of the following year, more than 50 per cent of seed embryos were seeded when they emerged. The processed seed is distributed to a well-established nursery at a distance of 5 x 5 cm, with a bed of 1. 2 m wide, 20 cm high and 30 cm wide. Seeds are then planted with 1:1 corroded soil and grass ash, which is about 1. 5 cm thick and is then covered with a needle or weed on the side of the twilight, which is suitable for soil-free water, watering and wetting. A small proportion of the seedlings were grown in august of that year, and most of them will not grow until may of the third year. Seeds are growing slowly, and three to four years later, the pelican seedlings become visible roots. (ii) root-strength reproduction. Root-strength breeding is divided into chrystals with no chrystals and chrystals with 100 per cent and 92 per cent of activity with no chrystals at the time of production; the growth of chrystals is 1. 5 to 2. 5 times greater than that without chrystals. At present, production is mainly dominated by the reproduction of bulges. The method of breeding sprouts is to take the root of the sprout, which is vertically in the direction of the main axis of the root, cutting with a length of 3 to 4 cm of the sprout, screeching the wound, drying it in the cold air, then growing it in accordance with the standard practice of the field, and in the spring of the following year, seedlings are available, while the rest can be dried for sale。
Plantation management techniques (i) varieties selection. (ii) the selection of land for cultivation, which is flat, irrigation-friendly, well-drained, highly fertilized and organically fertilized sandy and fertile sandy or red-border soil, in which the production and quality of pelican heavy buildings is high and the cultivation of marginal and compact soils is strictly forbidden. (iii) the favela, which is a fungus plant and has no radiance, should be built before seeding or planting. A pedal of 3. 6 x 4 m may be laid with a stake or concrete stake of 2. 2 m in length and 10-12 cm in diameter, with a depth of 40 cm in the ground, with a barbed wire on the top of the pedestal and a barbed wire on the edge, and with the other end of the barbed wire being pulled to the ground. A 70 per cent shade-covered sunnet should be placed on a barbed wire, which should be considered for subsequent convergence and expansion. In winter and snowy areas, piping should be planted, and once seedlings are planted (mid-october), sunnets should be brought together in time for their expansion before the next april. (iv) land consolidation 1. Land is selected for cultivation and cleared, pre-harvest crops are carefully cleared of impurities and residues, and fires are used to prevent or reduce the occurrence of pests and diseases in the coming year. After the clean land, decomposed farmers are spread evenly on the ground, applying 2,000-3000 kg per acre, then ploughing more than 30 cm with ploughs or machines and tanning for a month to eliminate insect eggs and disease. And then it's broken to the ground. (b) the soil shall be razed and razed. The slopes of the plots are applied to the mountains to facilitate drainage during the rainy season. In order to facilitate management, the surface should not be too wide, with a width of 1. 2 m, 25 cm high and a width of 30 cm wide, to connect the ditches and ensure that the rainy season is smooth and open to the fields。
(v) replanting. At this time, the piping roots of the plant are growing faster, and organs such as flowers and leaves are fully developed within the sprouts and flourish after seeding. 2. Cultivation density is 15 x 15 cm, with 18 to 20 million plants per acre. 3. The method of planting is to open trenches horizontally and in depths of 4 to 6 cm, and to plant seedlings according to planting specifications, it is necessary to place the top buds upward, with the soil of the second ditch covering the previous ditch, such as push. When it is finished, the surface is covered with pine needles or straw, the thickness of which is suitable for soil-free conditions and acts as a warmer, wetter and weed protection. The plant is then watered on the basis of the soil so that the soil is wet。
(vi) field management fill
The soil moisture should remain in the range of 30 to 40 per cent after the relocation of the filament. Following seedlings, spraying can be used where conditions exist to increase air moisture and promote the growth of the fir-heavy building. Before the onset of the rainy season, attention should be paid to the ditches in order to keep the drainage open. During the rainy season, attention should be paid to drainage, and water should be cut off from the surfaces and trenches. The fading plume is perishable, leading to the death of plants and reduced yields. When weeding is cultivated in china, weeds should be removed as soon as possible, so that there are no weeds in the fields. The weeds around the fifeng building were removed first with hand and then the other weeds were lightly removed with a special pickle. The grass must not hurt parts of the ground or the stubbed roots of the fahrenheit. In general, weeding and pine soil are combined. 3. Fertilizers in the fifi heavy buildings are predominantly organic, supplemented by compound and various trace elements. Organic fertilizers include fully decomposed farm fats, animal faeces, oil and grass ash, crop straw, etc., and the application of human urine is prohibited. Organic fertilizers should be stacked for more than three months before they can be applied (with calcium phosphate). Fattening of 1,500 kg per acre was carried out once in mid-may and late-august. The application of organic fertilizers should be accompanied by the application of n, p, k fertilizer in accordance with the growth of the fahrenheit building. The rate of n, p and k fertilization in the fizzy building is generally 1:05:1. 2 and urea, calcium per phosphate and potassium sulphate are applied on an acre basis at 10 kg, 20 kg, and 12 kg; fertilisation is applied with either fertilisation or water, which should be followed by water once or before rain. The fahrenheit complex has a large area of leaves that can be fertilized for plant growth during its boom (july-august), with 0. 5 per cent urein and 0. 2 per cent potassium phosphate sprayed once every 15 days, 3 times. The spray should take place in the middle of the sun. The non-farming field of the fahrenheit building shall remove the fruit by hand after the expansion of its pellets, so as to concentrate its nutrients on its nutritional growth and promote the growth of its roots。
(vii) pest management
(1) black-band disease begins at the tip of the leaf or its foundation and produces round- or near-round disease classes, sometimes spreading to the axles, forming leaves and dead. The application of 1 per cent of the venom agent 300-500 times the fluid, or 50 per cent of the methyl sulfur elixir suspension 1,500-2,000 times the fluid, or 50 per cent of the humid powder 1000-1,500 times the fluid, is all good。
(2) rodent disease. Most of the disease occurs during the nursery period, with high temperatures and heavy rainfall in the field. In the first instance, yellow and brown spots were produced in the tubular base, which spread, with the folates falling underwater and, in severe cases, the tubular moistly decomposition. Control measures: 1 rotation with a herbal crop for more than three years; 2 transfer pre-plant seedbeds with 50 per cent of the filamentable powder used as “sorting powder”; 3 de-sorts; 4 pre-infection ponds with 95 per cent of the enzymes of humid powder every 10 days and 2-3 per cent in succession。
(3) gold turtles endanger leaf blades with insects (screw bean worms) and eat rods and rods with larvae (white earth beverages) to affect the growth of insect buildings ... Measures to prevent and combat them; night fires lead to insects, and trichlorfon is sprayed with cuisine leaves to trap larvae; 5% of the thionate granular agent is sprayed in the whole area with 1. 5 to 2 kg。
Collection and processing
(i) the timing of the harvest. The combination of production and the content of the medicinal ingredient is the best for the piping of seed seedlings in the 6th to 8th year after the planting; for the 4th to 5th year after the planting of the sprouts. In the fall, before and after the fall, the strewn floor of the pelican complex in october-december, until the spring of the following year, before the beginning of the spring, the harvest was possible by march. (ii) the method of harvesting shall be chosen to remove the roots from the sun and, to the extent possible, to avoid damage to the roots and ensure their integrity. Most of the heavy roofs are grown on top of the surface and are easily poached, but care must be taken to keep them intact; first, they cut their leaves, then dig 40 cm deep with clean head, then dig them from the side, dig them out, shake them down, wash them clean, and then dry them with fresh slices, two to three millimeters thick. In the middle of the day, a microfire of 30°c can be used to dry it so that it does not paste the glucose。
(iii) production processing; it is best for the strong, solid, white and pink-footed。
(iv) packaging storage. Packaging materials for the fir heavy buildings shall be made of dry, clean, non-odour-free and non-quality-impaired materials, and packaging shall be robust, sealed, high-tide, protective of quality, and packaging materials shall be easy to recover and degradable. The name, class, quantity, harvest time, location, certificate of eligibility, and the person responsible for acceptance are indicated on the overpack label. Conditional bases indicate pesticide residues, analysis of heavy metal content and pharmaceutical content. Packed pharmacological pharmacists are stored in specialized warehouses that are clean, dry, cool, ventilated and non-savoury in a timely manner, with regard to the prevention of cartilage, rodents and pests, as well as regular inspections。
