Key Technical Points for Large-Scale Cultivation of Licorice with High Quality and High Yield
Field Management 1. Intertillage and weeding: After the seedlings emerge completely, intertillage and weeding should be carried out promptly so that there are no weeds in the field. For ridge planting, three hoeings and three ridgings can be done; for bed planting, weeds on the bed surface should be pulled out. This is the key to high quality and high yield. Where conditions permit, closed weeding can be carried out after sowing and before seedling emergence, using Douhuanglong (20% chlorimuron-ethyl) wettable powder 2 bags/mu mixed with acetochlor 2-4 bottles/mu and sprayed over the field. After seedling emergence, herbicides killing monocotyledonous plants can be sprayed to eliminate weeds.

What kind of tree species is the tetraploid large-leaf black locust?
The tetraploid large-leaf black locust is a superior variety selected through years of dedicated research and experimental comparison from among several excellent polyploid black locust clones introduced from abroad. The tetraploid large-leaf black locust is an artificially induced tetraploid plant, characterized by fast growth, large leaves and high biomass. Its leaf width is more than 2 times that of the common black locust, and its compound leaf dry weight, single leaf dry weight and total leaf dry weight are 1.5 times or more those of the common black locust respectively. Compared with the common black locust, the tetraploid large-leaf black locust has a denser crown, thicker branches and a stronger photosynthetic capacity. Tetraploid

Rare Large Stand of Endangered Natural Yew Trees Discovered in Zhashui, Shaanxi
A rare large stand of natural yew trees, numbering more than 100,000, has recently been discovered in Zhashui County, Shaanxi, which is located in the Qinling Mountains. Some experts say that the yew is an endangered tree species preserved from the Quaternary glacial period, and that the extensive area and large number of this natural yew forest are rare. It is understood that Zhashui is located on the southern slope of the Qinling Mountains, in the transitional zone between the subtropical and warm temperate zones, with abundant rainfall and a forest coverage rate of 78 percent. It is rich in plant resources and has been known since ancient times as a "natural medicine storehouse." In Dongyuan Gully, Fenghuang Town, a yew was once found with a trunk circumference of 2.18 m, a canopy covering half a mu of land, and an age of more than 1,900 years.

Detailed Explanation of Prevention and Treatment Methods for Common Diseases in Large-Scale Rabbit Farms
A large-scale rabbit farm mainly follows the immunization program, injecting vaccinations against three diseases: rabbit hemorrhagic disease, pasteurellosis, and clostridial disease. Secondly, prepare complete nutritional pelleted feed according to the nutritional needs of rabbits; feeding moldy feed is prohibited. As long as the feed is stabilized on a rabbit farm, the rabbit herd will stabilize. Rabbit diseases are fewer compared to chicken and pig diseases. However, rabbits are delicate animals with poor resistance; if a rabbit falls ill, it is very difficult to cure. For example, if a pig has diarrhea for 2 to 3 days it will not die, but if a rabbit has diarrhea for 2 to 3 hours it will die. Therefore, it is particularly important for rabbit farms to carry out epidemic prevention and hygiene, and to do a good job in feeding and management.

Six key management practices to focus on after transplanting spring eggplant in a large arch shed
I. Temperature control For spring eggplant cultivated in a large arch shed, from transplanting until the seedlings recover, the shed should be kept closed to retain heat, keeping the temperature inside the shed at 28°C-30°C during the day and 15°C-20°C at night as much as possible. After the seedlings recover, attention should be paid to ventilation, keeping the shed temperature at 23°C-25°C during the day, generally not exceeding 33°C. II. Fertilizer and water management Under conditions of good soil moisture, water as little as possible before the first eggplant reaches the size of a walnut, to raise soil temperature and prevent flower and fruit drop. When the first eggplant reaches the size of a chicken egg, apply 10 kg of urea per 667 sq m along with watering. After that, appropriately increase the frequency of watering according to soil moisture.
