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.

Rice direct seeding machine successfully developed, efficient and versatile, boosting rice sowing
Recently, a "Multifunctional Soil-Covering Direct Seeding Machine Rice Mechanical Direct Seeding Field Demonstration" organized by the China National Rice Research Institute was held in Buqiao Village, Fuyang City, Zhejiang Province, with more than 40 experts from home and abroad attending the field observation event. In recent years, China's rice mechanical transplanting technology has developed rapidly, and a number of different types of transplanters suited to China's rice production have been developed and produced. However, the development and research of rice direct seeding machines and mechanical direct seeding technology have lagged relatively behind, and no mainstream rice mechanical direct seeding technology has yet taken shape. To overcome the problems of poor seedling establishment, easy lodging, premature aging, and difficult and costly weed control

Degradable-film controlled-release fertilizer for rice successfully developed in Hunan Province
The Soil and Fertilizer Institute of Hunan Province has developed a degradable-film controlled-release fertilizer for rice that can be widely applied in rice-growing regions of China with no side effects. Using natural and semi-natural polymer materials as the main coating components and adopting a self-developed new fluidized dual-spray-bed coating process, the Soil and Fertilizer Institute of Hunan Province developed a degradable-film controlled-release fertilizer whose nutrient release can be artificially controlled within 30 to 330 days. This controlled-release fertilizer is non-toxic, completely degrades within 2 years after being applied to the soil with no residue, and can reduce fertilizer pollution of the atmosphere, soil, water bodies and other environments.
