【安康】全力推动马铃薯产业提质升级

Core Viewpoint - The development of the new potato variety "Qin Yu 36" aims to address the challenges faced by the potato industry in the Qinba Mountain area, including variety degeneration and unstable yields, thereby enhancing local agricultural productivity and farmer income [1][2]. Group 1: Research and Development - The "Qin Yu 36" potato variety, developed over 15 years, has been registered as a national non-major crop variety, specifically tailored for the Qinba Mountain region [1]. - The breeding process involves meticulous steps, including hybridization, seed selection, and multiple rounds of field trials to ensure the emergence of superior traits [2]. - The new variety exhibits moderate resistance to late blight and viral diseases, along with high vitamin content and optimal starch levels, making it a versatile choice for local farmers [2]. Group 2: Agricultural Practices and Technology - The use of virus-free seed potatoes is crucial for restoring seed quality, with the potential to double yields compared to traditional varieties [4]. - Innovative agricultural practices, such as crop rotation with sweet corn and the implementation of integrated water and fertilizer management, have significantly improved land productivity, achieving yields over 2,500 kg per acre [4]. - The establishment of a "research + base + order" mechanism has led to increased farmer incomes, with over 20 households earning an average of 20,000 yuan annually [4]. Group 3: Market Potential and Economic Impact - The "Qin Yu 36" potato, cultivated in selenium-rich soil, has a selenium content of 0.351 mg/kg, meeting the standards for selenium-rich agricultural products without additional fertilization [5]. - The variety's adaptability across regions, including southern Shaanxi, western Hubei, and eastern Chongqing, presents significant market expansion opportunities [5]. - The local agricultural sector is transitioning from traditional practices to modern marketing strategies, with increased demand from farmers and businesses for the new potato variety [5].
