Core Viewpoint - The rice planting demonstration area in Huicheng District achieved a yield of 538 kg per mu, indicating a stable increase in production and significant demonstration effects [7][12]. Group 1: Agricultural Practices and Techniques - The rice planting demonstration utilized unified pest control and the "three controls" fertilization technique, resulting in good outcomes [6][7]. - The area under demonstration covers approximately 2,000 mu, primarily planting varieties such as Nanjing Xiang and Huahang Xiangyin [10][11]. Group 2: Production Statistics - Preliminary statistics indicate that Huicheng District's spring grain planting area for 2025 is 89,083 mu, an increase of 150 mu compared to 2024, with early rice planting covering 70,033 mu [12][13]. - The local agricultural department's promotion of good varieties and methods has led to increased acceptance among rice growers [16]. Group 3: Economic Impact - The adoption of high-yield rice varieties has improved farmers' income, enhancing their enthusiasm for rice cultivation [17]. - The rice harvesting in Huicheng District is expected to conclude between late July and early August [19].

Group 1: Wheat Harvesting in China - The wheat harvesting season has successfully concluded in key regions such as Southwest and Huanghuaihai, while harvesting in Northwest regions like Xinjiang and Gansu will continue until autumn [1] - In Qingyang, Gansu, the summer wheat mechanization rate reached over 99%, with the entire wheat harvest expected to be completed by the end of June [3] - The area planted with winter wheat in Qingyang is 160,000 acres, with agricultural technicians conducting experiments and collecting data for future breeding and production [5] Group 2: Desert Wheat Cultivation in Xinjiang - In Xinjiang's Kunyu City, over 40,000 acres of desert wheat are being harvested, utilizing a "good variety + good method" agricultural system to enhance wheat yields [6][10] - A farmer reported harvesting 800 acres daily with an expected yield of 700 kg per acre, indicating a favorable economic outcome this year [8] - The agricultural department in Kunyu, in collaboration with a research team from Beijing, has developed a system to convert desert land into productive wheat fields [10][12] Group 3: Biological Pest Control in Corn Fields - In Shenyang, Liaoning, a biological pest control method using "bee balls" containing parasitic wasp eggs is being implemented to combat corn pests, specifically the corn borer [13][15] - Each bee ball can hatch over 5,000 parasitic wasps, which are natural enemies of the corn borer, significantly reducing pest populations without chemical pesticides [15][19] - The city has allocated 5.2 million yuan to promote this technology over an area of 340,000 acres, highlighting a shift towards environmentally friendly pest control methods [21]
