New upland rice variety developed in Shandong, agronomist Xu Defang successfully breeds it
In the golden autumn season, a new upland rice variety carefully cultivated over 3 years by Xu Defang, an agronomist at the Dongying Branch of the Shandong Academy of Agricultural Sciences, has achieved a bumper harvest. According to calculations, it yields more than double that of the current upland rice variety 297, with a yield of 600-650 kg per mu, marking a breakthrough in China's upland rice breeding. Xu Defang used more than 30 ancestral lines provided by Professor Li Zichao of China Agricultural University, discovered a dwarf-stalk mutant line from the tall-stalk line 33-1, and from it selected a group of 9 lines, namely early-maturing, glutinous, early

Virus-free Technology and Industrial Development of Superior Potato Varieties
Aiming at the main problems currently existing in potato production, this study seized the favorable opportunity of planting-structure adjustment and extensively introduced superior potato varieties from home and abroad. Through trials and market-demand surveys, "Luyin No. 1" was selected as the main cultivar for Qingdao, with Kexin No. 3, Kexin No. 4 and Huayuan 525 as companion cultivars. Through systematic research on virus-free technology, rapid propagation technology and the acclimatization and transplanting technology of virus-free test-tube plantlets, the optimal virus-free protocol for potato was determined: taking 0.1-0.2

Potato Harvester Successfully Developed, Mechanized Harvesting Realized
On July 17, at the provincial potato mechanized planting and harvesting on-site demonstration meeting held in Xiazhaizhai Village, Nianbo Town, Ledu County, Qinghai Province, it was observed that a single-operator potato harvester produced and developed by a provincial private enterprise completed the potato harvest of a 8-fen plot in less than 40 minutes, equivalent to a whole day's workload of 10 laborers, while the machine's selling price was less than 1500 yuan. The staff of the Qinghai Provincial Agricultural and Animal Husbandry Machinery Extension Station distributed and promoted 40 such potato harvesters with an operating efficiency of 1.2 mu per hour to 20 grassroots stations on site.
