Glycyrrhiza arborescens standardized cultivation techniques

Lysimachia oleracea is a perennial shrub-like herbaceous plant of the leguminous family, also known as landing money, copper grass, fake peanuts, horseshoe grass, and mountain beans. It is commonly used in Guangdong and Guangxi. G. lucidum Sweet, cool, with heat, diuretic, row of stone effect, for the treatment of urinary tract infections, urinary tract stones, cholelithiasis, acute icteric hepatitis and other diseases. Lysimachia is widely distributed in China's Guangdong, Guangxi, Yunnan, Sichuan, Fujian and other provinces and regions, our province is mainly produced in Dongguan, Baoan, Zengcheng, Boluo and other places. Wide money grass is like high temperature, long daylight, good water, fertilizer, intolerable cold, bogey shade and stagnant water. Spiritillaria odoratum requires less soil, yellow loam soil, red loam soil, and sandy loam soil can grow, and barren soil can also grow, but it is better to use sandy loam soil with good water permeability. First, the choice of site preparation (1) nursery should choose a flat terrain, near water, fertile soil, loose and moist, well-drained sandy loam for nursery. In the winter of the first year, in the winter, after weathering in the winter, the per acre Shifu cooked l 500 kg, after cultivating once, the ground leveling, starting from 100 to 120 cm wide sorghum, and then leveling the glutinous surface, to be treated sowing. (2) Flat or gentle slopes can be selected for planting. Fertile soil is loose, and well-drained sandy loam and loam soil are used as planting areas. Before planting, plowing and cultivating are carried out, and 3000 kg of fertilizer is applied per acre, such as manure and grass ash. After the application, the manure is mixed and the soil fertilizer is evenly mixed, and then the width is 120 cm. If the basal fertilizer is insufficient, you can also apply the basal fertilizer into the hole when planting open holes. Second, the breeding method Lysimachia crassipes is the use of seedlings nursery and cutting seedling breeding. (1) Seeding Seedling 1 Seed and Seed Reserve: In October of each year, the plots with moderate plant growth, robust, and no pests and diseases are selected as reserved land. Appropriate application of phosphorus and potassium fertilizer, in the flowering and saliva stage with 3% superphosphate calcium leaching solution sprayed several times, when the majority of the fruit pods turn from yellow-green to tan, the whole plant will be cut back, spreading the sun to make it crack At the time; with a small wooden tap, so that the seeds fall off, and then remove the straw, the seeds collected, remove impurities, into the bag, set dry place. 2 sowing seedlings: In late March to mid-April each year, when the temperature rises above 20 °C sowing. When sowing, the seeds and several times of dried river sand are ground into the mortar for 3 to 5 minutes to remove the wax from the outer layer of the seeds so that the seeds can absorb water and germinate. The ground seeds are soaked in warm water at 40°C. 24 hours, remove and dry water, 1 part of seed and 3 parts of plant ash or fine soil and mix well. In the whole seed bed, open the horizontal ditch by 20cm spacing, deep 3~4cm, and evenly sow the seeds into the ditch. Cover soil to not see the degree of seed, cover the grass, watering. About 10 days can emerge. Out of Qimiao will soon be covered with grass cover, after the strengthening of management, often watering, cultivating weeding, seedlings topdressing, seedling length 10 to 15 cm can be planted. (2) Cutting seedlings Every year from February to April or November, the stalks that grow thickly, densely and without pests are selected as cuttings and cut into 10 cm long cuttings with more than three sections. In the whole area of ​​the nursery, the ditch is laid at a distance of 12 cm, and the cuttings are inserted into the ditch at a distance of about 5 cm from the planting site. Cover the grass surface with moisturizing and moisturizing, and keep it moist and moist with water to facilitate germination. Early spring and winter seedlings should be kept in arched plastic film sheds in areas with cold weather. It is advisable to open ventilation in sunny and windy conditions. The temperature can be removed when the temperature returns to 20°C. During the nursery period, strengthen management, diligent weeding and fertilization. After the seedlings grow 10 centimeters high and grow several roots, they can be planted. Third, planting and field management Planting will be planted every year from April to May. Choose rainy days or sunny evenings to plant in well-organized planting areas. The fertile soil will be planted at a row spacing of 35 cm and 25 cm. The medium fertility soil will be planted at a row spacing of 30 cm and 20 cm, and the hole depth will be 5 cm. , The hole is applied with thin human and animal waste water, l ~ 2 strains per hole seedlings, soil compaction, watering foot setting root water. Planting seedlings per acre 7000 to 8000 strains. 2. Field management (1) After the cultivating and weeding seedlings have survived, they should be intensively cultivated and weeded once a month. The cultivator should be shallow hoeing, keep the ground free of impurities, and the soil not compacted to facilitate plant growth. After the plant is sealed, the cultivator will not be cultivated. Weeding can be removed by hand. After the seedlings were planted in Daejeon, during the second topdressing, the appropriate cultivating earth pressured the basal sprawl within 10 cm from the ground, prompting its adventitious roots to penetrate into the soil to form roots, in order to increase the plant's ability to absorb and assimilate fertilizers. (2) Dressing Cicus lucidum is a kind of fertile plant. In addition to applying base fertilizer, it is necessary to carry out multiple top dressings, mainly nitrogen topdressing. After the first time, after the seedlings have survived, the manure water per acre is 500kg. After that, the cultivating and weeding and topdressing are performed once a month. Each acre, each person applies 2000kg of livestock manure or 10kg of urea to the water. After harvesting for the first time in mid-August, 2000 kg per acre was cooked and applied around the plants. After the new germination seedlings were 10 cm long, they were topdressed and 2000 kg of livestock waste per acre was applied. Or urea l0 kilograms of water, then once a month. (3) In the event of drought in the weather within five days after planting and rowing, the water should be sprayed once a day in the evening to keep the cave soil moist to increase the survival rate. According to the weather conditions, watering and irrigation can be carried out in due course. After the rainy season, the water in the ground should be promptly removed to facilitate root growth. (4) Diseases and pests control hazards The diseases and pests of Lysimachia roxburghii mainly include root rot, blight, mildew, armyworm, caterpillar and aphids. In production, it is necessary to strengthen field management, cultivate robust plants, create ventilation and light transmission conditions, dilute irrigation, prevent impregnation, and reduce the occurrence of pests and diseases. If a diseased plant is found, it must be removed promptly and burned centrally. To use high-efficiency, low-toxicity, low-residue pesticides to control pests and diseases, we can use a 50% tuzet WP to spray 600 times of foliar against blight, and use 50% thiophanate-methyl wettable powder 1000 to 1500 times to prevent mold. Ill, kill pests with dimethoate and trichlorfon. When root rot occurs, water should be sprayed with 0.3% lime water at the onset to prevent spread. V. Harvesting and processing of Lysimachia lanceolata is not blooming blue-green grass, harvested in summer and autumn, when the local stem vine grows to 50 to 80 centimeters in length, or harvested immediately after the emergence of lateral vine buds. Harvesting should follow the principle of cutting large and small, that is, short branches left for the next harvest. Broad money grass can be connected for 3 to 4 years. The autumn sowing seedlings can be harvested twice. The first time in July-August, the vines were cut with a hoe at a distance of 10 cm from the ground in order to regenerate new shoots. Then cultivator weeding, combined with topdressing. The second harvest was carried out from November to December and the flat ground was cut. Will cut off stems and leaves to remove impurities, cut into sections, dried (not suitable for exposure, otherwise leaves easily fall off) or fresh. To be placed for a longer period of time, pay attention to the sun, so as to avoid mildew mold. Gledoosteum general produces 400 to 500 kilograms of dry product per mu, with a high yield of 800 to 1,000 kilograms, and an output value of 2000 to 4,000 yuan.
