Detailed Explanation of Key Points on Licorice Harvesting and Processing Technology
Harvesting and Processing Licorice is generally harvested after 1-4 years of cultivation. In Hebei and Beijing, it is harvested after 1-2 years of cultivation; in Inner Mongolia; Northeast China, and **, it is harvested after 3-4 years of cultivation. There are currently 2 cultivation methods: one is direct seeding, and the other is raising seedlings in the first year and transplanting in the second year. When transplanting, plant them flat and lay them horizontally in the field to facilitate harvesting. The first method is simpler and requires less labor; the second method is suitable for small-area household planting with intensive cultivation. For large-area planting, harvesting is a problem, and manual digging is very difficult. After many years of testing, a 55-type Iron Ox rubber-tired tractor can be used, with a plowing depth of about 45 cm, plowing one row at a time, and then manually using a four-tooth rake to pick out the licorice roots plowed out, then plowing the second row. One tractor paired with 10 workers can generally harvest about 10 mu per day, and the root damage rate is also somewhat lower than manual digging. The residual roots lost in the field are about below 10%, meeting the requirements, opening a new path for large-area licorice planting. After the harvested licorice roots are dried in the sun for a few days, use manual shears or a guillotine to cut off the rhizome heads and tails, and cut out licorice strips for cutting into oblique slices for export. The rhizome heads, fibrous roots, and tails are tied into bundles and used as hairy licorice for extracting licorice paste. For licorice grown for two years, the general dry weight of licorice strips is about 250-300 kg per mu, and hairy licorice is about 300 kg per mu. The output value per mu can reach about 4000 yuan.

Detailed Explanation of Key Points of Cotton Male Sterile Line Seed Production Technology
The cotton male sterile line seed production technology uses the insect-assisted pollination male sterile line hybrid seed production method, which overcomes the shortcomings of the currently widely applied cotton hybrid seed production method - the manual emasculation and pollination hybrid seed production method, such as being time-consuming and labor-intensive, high work intensity, complex management of seed production fields, and high seed production costs. The labor usage can be reduced by more than 50% compared with it, and the purity of hybrid seeds can be further improved. It is the most ideal way to produce cotton hybrid seeds. The cotton male sterile line seed production technology is to breed a transgenic insect-resistant nuclear double recessive male sterile line with a recessive low-gossypol marker trait

Detailed Explanation of Key Points of Scientific Chemical Topping Technology for Cotton
Chemical topping of cotton is one of the most difficult techniques for cotton farmers to master. According to research by relevant departments, chemical topping of cotton can affect 30% of cotton yield, but most cotton farmers apply chemical topping blindly, so it is very necessary to promote a simple and easy-to-understand cotton chemical topping technique. The experience accumulated over many years is introduced below. The following is only reference data for Switzerland Reach TM cotton pruning Zhenbuluo; cotton farmers should use it flexibly according to soil fertility, climate and actual growth conditions. 7~10 days after topping (around July 25): use 40 ml per mu diluted in 15

Detailed Explanation of the Processing Technology of Ready-to-Eat Pickled Pepper Plumfish
Plumfish, also known as plum croaker, belongs to the family Sciaenidae and the genus Sciaena. It is an important species in China's marine fishing, with a large yield and a low price. Therefore, plumfish is generally used together with other low-value fish as a raw material for surimi processing. 1. Auxiliary materials: red chili peppers, Sichuan peppercorns, old ginger, garlic, refined salt, pepper powder, star anise, cinnamon, white granulated sugar, peanut oil, etc. 2. Processing flow: cleaning → descaling, gill removal, gutting → cleaning → soaking → seasoning → precooking → cleaning and cooling

Detailed Explanation of Canned Surimi Processing Technology
Canned surimi processing was developed on the basis of surimi product processing. Products such as boiled fish balls, fried fish balls, and seasoned surimi can all be processed into canned foods. These canned products have the unique flavor of surimi products. Here, seasoned eel surimi canned product is taken as an example. (1) Process flow: raw material handling, mincing, grinding and kneading (with seasonings added) -> filling into cans -> pre-sealing -> vacuum sealing -> sterilization -> cooling. (2) Operating points: 1. Raw materials: select iced fresh or frozen eel with good freshness; deteriorated fish must not be used. 2

Detailed Explanation of Key Points of Electroejaculation Semen Collection Technology in White Raccoon Dogs
In recent years, colored fur has been consistently popular in the fur market, which has driven a surge in breeding of colored fur-bearing animals. As one of the few colored varieties among raccoon dogs, the white raccoon dog has seen rapid growth in popularity. In 2005, the price of breeding males exceeded 4000 yuan each, far surpassing other fur-bearing animals and even surpassing imported Finnish foxes. There is no shortage of hype factors here, but the main reason is the shortage of white raccoon dogs. Because the reproduction of white raccoon dogs is based on dominant inheritance, and lethal genes objectively exist in their own reproduction, white raccoon dogs must be mated with ordinary raccoon dogs

Detailed Explanation of Rapid Propagation Technology for the Anti-Cancer Plant Hybrid Yew
Hybrid yew 8502 is one of more than ten cultivated lines of Taxus media (Taxus media), and its fast-growing nature and wide adaptability are superior to other lines, allowing it to be planted in most regions of China. Taxus media is one of the yews approved by the U.S. FDA for use in extracting the anti-cancer drug "paclitaxel." The paclitaxel content in the branches and leaves of 4- to 5-year-old Taxus media is higher than the "paclitaxel" content in the bark of natural yew trees grown for 70 to 80 years. Wild yews, including domestic varieties of yew,
