Harvesting Methods and Technical Key Points for Licorice
For licorice grown from seedlings and transplanted, it is best to harvest at 2-3 years, with autumn harvesting giving the best quality. Before harvesting, the stems and leaves can first be cut off for use as livestock feed. Then harvest with a subsoiler or a special licorice harvesting plow, trying as much as possible to prevent damage to the root bark and premature root breakage. Shake the soil off the dug roots; they must not be washed with water. While still fresh, remove the remaining stems and fibrous roots, cut off the root heads, and grade them according to root thickness; the root strips must not be shorter than 20 cm. After trimming and cutting into sections, dry the licorice in the sun by grade. When sun-drying licorice, pay attention to protecting it from rain, and the drying yard must be free of contamination. When the licorice is half-dried, tie it into

Licorice Disease Prevention and Control Methods and Key Technical Points
(1) Rust disease: When infected, yellowish-brown scar-like lesions appear on the underside of the leaves. After the epidermis ruptures, brown powder is released; this is the uredinium of the pathogen. From August to September, dark brown telia form, causing the leaves to turn yellow and wither, and in severe cases to fall off. Control methods: Apply more phosphorus and potassium fertilizer to improve the plant's disease resistance. Remove diseased plant debris and burn it in a centralized manner. At the early stage of the disease, spray with 15% triadimefon at 1000 times dilution, or 97% diniconazole at 400 times dilution. (2) Brown spot disease: It damages the leaves, and affected leaves develop round or irregular lesions. The

Detailed Explanation of Key Cultivation Techniques for Upland Rice in Heilongjiang
This year, farmer Sun Baoxiang of Heli Village, Renmin Town, Anda City, Heilongjiang Province, introduced the new upland rice variety Hanadao 65 from the Chinese Academy of Agricultural Sciences in Beijing, and achieved success in a trial planting of 10 mu. Due to severe drought this year, but with the careful cultivation by technicians and farmers, the actual harvest of upland rice grain in autumn was 2521 kg, with an average yield of 252.1 kg per mu. Although the yield of upland rice was not high during the three years of major disasters, the success of this upland rice planting has blazed a new path to wealth for the future development of upland rice production. 1.

Kenya Launches New Upland Rice Variety
More than 300 farmers in Kenya are benefiting from a newly developed rice variety that has a shorter growing period, matures faster, and can also withstand harsh weather and disease. This rice variety, designated NaricIII, is an upland rice variety. However, unlike other upland rice varieties such as SupericaI, II and Abironi, which mature after 120 days and 5 months respectively, this new variety can mature in just 3 months. In addition to its high maturation rate, what pleases farmers most
