Core Viewpoint - The article highlights the innovative approaches taken in Jilin Province to improve saline-alkali land through the cultivation of water bamboo (茭白), which shows significant potential for soil improvement and increased agricultural productivity [2][4][12]. Group 1: Saline-Alkali Land Utilization - Jilin Province has over 6.7 million acres of saline-alkali land, with more than 2 million acres already developed [2]. - The cultivation of water bamboo in saline-alkali areas has demonstrated a decrease in soil pH from an average of 9.32 to 9.0, indicating effective soil improvement [2]. - Water bamboo's extensive root system helps break up soil compaction and enhances organic matter in the soil through the return of straw [6][4]. Group 2: Seedling Cultivation Innovations - The use of substrate seedling cultivation has replaced traditional soil-based methods, utilizing local agricultural waste to create a nutrient-rich growing medium [9][11]. - New substrate seedlings show a 20% increase in root mass and a reduction in the acclimatization period by 3 days compared to traditional methods, with a projected reduction of 100,000 tons in black soil extraction this year [11] [7]. Group 3: Technological Advancements in Agriculture - Advanced techniques, including the use of green biological agents and drones for applying soil amendments, have been implemented to improve the quality of saline-alkali land [13][14]. - Over 100 saline-alkali land management projects have been initiated in Jilin Province, resulting in the addition of over 800,000 acres of arable land and an expected annual increase in grain production of nearly 1 billion pounds [14].
