“吃”有机肥“穿”防晒衣 雨养麦田增产五成

Core Insights - The research team led by Professor Li Tingliang from Shanxi Agricultural University has developed a new agricultural technology that significantly increases wheat yields in arid regions by approximately 50% through the use of organic fertilizers and sunshade measures [1][2] Group 1: Technology and Implementation - The innovative technology, named "Drought Wheat Summer Fallow Organic Compound Soil Improvement and Year-Round Coverage Water Conservation Yield Increase Technology," has been successfully applied in demonstration fields, achieving a wheat yield of 288 kg per mu, compared to the traditional rain-fed wheat yield of 200 kg per mu [1] - The technology involves applying specific organic compound fertilizers after wheat harvest, deep plowing the soil to mix straw and residues, and using shade nets to cover the ground [2] - In trial fields in the Jin Nan region, wheat yields reached 353 kg per mu, significantly higher than traditional methods, demonstrating the effectiveness of the technology [2] Group 2: Regional Context and Challenges - The Loess Plateau region experiences limited annual rainfall of about 500 mm, primarily concentrated from July to September, with only 20% to 50% of precipitation being utilized by plants due to high evaporation rates [1] - The main challenge for stable and high crop yields in the Loess Plateau is insufficient water, as the water-intensive growth period of winter wheat does not align with the local rainfall season [1] - Effective water collection and conversion into soil moisture before sowing is crucial for achieving high yields in drought-prone wheat cultivation [1]
