How to grow licorice for high yield? A full breakdown of the technical key points
1. Soil selection. Choose deep soil layers, good drainage, high-lying terrain, and sandy soil and sandy loam soil with relatively high calcium content. Waste flats and waste slopes with slightly alkaline soil and a pH between 7 and 8.5 can all be cultivated. Plots with low-lying terrain and heavy clay soil must not be planted. 2. Variety selection. Choose the new "Wosheng licorice" variety suitable for artificial cultivation. This variety has the following characteristics: First, strong adaptability, drought resistance, cold resistance, salt-alkali resistance, heat tolerance, and tolerance to poor soil. Its temperature adaptation range is 43 to 45°C. In areas with severe water shortage or relatively dry conditions, no wilting or death has been found, and it can adapt to weakly alkaline calcareous soil. At the same time, it is suitable for intercropping with young forest and fruit trees; second, a short growth cycle. With seedling raising and transplanting, the seedlings grow for 3 to 4 months, and after planting they can be harvested after 8 to 10 months of growth; third, fast growth. Because of its prostrate growth habit, combined with artificial cultivation techniques, it grows horizontally at 30 cm on the soil surface, and its absorption rate of natural conditions such as light, water, and fertilizer is high, so its growth speed is fast. Thirty days after sowing, 3 to 4 true leaves appear. At 60 days, the plant height is 30 cm, the root length can reach 20 cm, and the diameter is 0.5 cm; fourth, harvesting and processing are simple. All operations can be mechanized, less labor is used, and it can be sold after being naturally dried to 80 percent; fifth, high yield and good quality. The yield of medium rough grass per mu is more than 500 kg, and high-yielding fields can reach 800 kg. The skin is red, there are few branches, and the strips are uniform. It meets the standards of the national pharmacopoeia and complies with the germplasm requirements for building a GAP production base.

What are the key techniques for high-benefit cultivation and management of licorice?
(1) Site selection and land preparation. Licorice has strong adaptability, and most soils can be used for planting except saline-alkali land. In autumn, apply barnyard manure or compost as base fertilizer, plow more than 20 cm deep, rake level and make beds 1 m wide and 17 cm high, and open small furrows on the bed surface for sowing at planting time. (2) Propagation methods. Use seed propagation and rhizome propagation. 1. Seed propagation. This method can be used to expand the area. (1) Seed treatment. Under natural conditions, the hard seed rate of licorice seeds is as high as more than 80%-90%. Pre-sowing seed treatment is the key to a high yield.

Detailed Explanation of High-Temperature Open-Air Cultivation Technology for Shiitake Mushrooms Using Sawdust
The technology of cultivating shiitake mushrooms (Lentinula edodes) using sawdust as the raw material under high-temperature conditions of 30°C breaks the seasonal restrictions of traditional shiitake cultivation, allowing production in all four seasons. The method is: add water to sawdust and boil for 10-20 minutes, scoop out, drain, spread out and air-dry. For every 1.5 kg of dry material, add 500 ml of a mixed solution made from the filtrate containing 0.1% carbendazim and 0.2% monopotassium phosphate, mix well and let cool, then place the culture material on pieces of plastic film of about 0.17 sq m, mix in 40%-50% spawn, crumble and mix thoroughly, pour onto another piece of plastic

Clever inoculation of shiitake mushrooms: master the method to achieve high yields
1. Dense inoculation increases the spawn points on the log segments. More spawn points means a larger area of spawn growth, allowing the mycelium to penetrate deep into the log segments and feed within a shorter time, reducing the chance of contamination by competitor fungi. 2. Deep inoculation: deeper spawn holes hold more spawn, which helps enhance drought resistance and reduces the stimulation of external temperature differences on the spawn blocks at the bottom of the holes. Under constant temperature and humidity, the mycelium inside the spawn blocks germinates quickly, and the survival rate improves. Drilling deeper holes increases the tangential depth of the wood, greatly raising the yield. 3. Early inoculation: under low-temperature conditions, the density and activity of competitor fungi in the air are low,

Success in Extracting Highly Effective Anti-Cancer Substance from Cloned Yew
Sichuan University professor demonstrates unique plant transgenic cloning technology, with the next step focused on anti-cancer plants. "We have already used transgenic cloning technology to successfully clone two plants with different genes, and the next step is to apply this technology to cloning the anti-cancer drug paclitaxel." Recently, Professor Wang Li from the Plant Research Laboratory of the College of Life Sciences at Sichuan University showed reporters a transgenic cloning technology little known to outsiders. A plant cloned from a leaf. In the laboratory, Professor Wang pointed to a green plant about 20 cm tall and said: "

Detailed Explanation of High-Efficiency Seedling Techniques for Taxus wallichiana var. mairei
Taxus wallichiana var. mairei belongs to the family Taxaceae and the genus Taxus. It is an evergreen large tree, an endangered plant worldwide, and is listed as a national first-class protected tree species. This tree species prefers a warm and humid climate and is mainly distributed in areas south of the Yangtze River basin below 1500 m in altitude. In our city, ancient trees are scattered in Liandu, Suichang, Qingtian and other places. The wood of Taxus wallichiana var. mairei has a fine texture, is lustrous and elastic, with purplish-red heartwood and strong decay resistance, making it a superior industrial timber; research has found that taxol and taxane extracted from its bark, roots and leaves have special preventive and therapeutic effects on cancer, leukemia and AIDS.

What are the highly effective pesticides for controlling rice skipper?
1. Optimal control period: This should be strictly timed to the peak egg-hatching stage and young larval stage of the rice skipper in the field, that is, July 29 to August 6 is the best period for pesticide application. 2. Targets for control: Rice fields with tender green growth, late transplanting and late development, late development after sitting, and seed-production maternal rice fields are all key target fields for control. 3. Protect natural enemy resources, prohibit the application of highly toxic pesticides, increase the parasitism rate of eggs, larvae, and pupae, and achieve pest control through beneficial organisms. 4. Chemical control: For rice skipper, use Qiansheng 8000 at 50 grams per mu, 90%

A Complete Analysis of the Key Points of High-Yield Cultivation Techniques for Two-Line Rice
Two-line rice has characteristics such as early and rapid growth in the early stage, smooth color transition in the middle stage, a long late-maturing period, tolerance to fertilizer and disease resistance, large panicles with many grains, relatively good grain quality, stable and high yield, and a more obvious yield-increasing advantage over three-line rice. Therefore, in recent years it has been promoted and applied over relatively large areas in various places. In practice, we earnestly implemented the "six improvements" measures for high-yield cultivation, gave play to the high-yield advantages of two-line rice, and achieved gratifying results. 1. Improve seedling-raising techniques and cultivate strong seedlings. According to the characteristic that two-line rice has little flexibility in seedling age, carry out classified seedling raising.
