摘要
为探究施用有机无机复合改良材料对酸化红壤旱地的改良效果,开展了配施有机无机复合改良材料(粗鱼粉与硅质石化粉重量比7∶3)对酸化红壤旱地的改良效果试验,连续种植两季小白菜,与常规施肥的小白菜产量进行比较.结果表明:有机无机复合改良材料可以改善红壤旱地的理化性质,使两季土壤pH值在分别提高了 5.37%和 8.27%,综合提高了 0.34 个单位;显著提高小白菜产量,两季分别增产 25.66%和 262.10%;同时有机无机复合改良材料也可以明显提升红壤旱地的有机质含量,两季平均提升了 30.97%;土壤中氮磷钾养分含量在两季播种前及收获后也得到明显提高.综合分析可知,有机无机复合改良材料对于红壤旱地的改良效果显著,在提高土壤pH值的同时改善土壤养分结构,提高了红壤旱地的生产力.
Abstract
To study the improvement effects of organic-inorganic composite materials on acidified red soil in dryland,we applied organic-inorganic composite materials(crude fish meal and silica petrochemical powder mixed in a weight ratio of 7:3)in the acidified red soil.Furthermore,we planted two consecutive seasons of pakchoi and compared the yield of pakchoi between different treatments.The results showed that the organic-inorganic composite materials improved the physical and chemical properties of red soil,increasing the soil pH by 5.37%and 8.27%respectively in the two seasons,with a comprehensive increase of 0.34.In addition,the organic-inorganic composite materials increased the yield of pakchoi in the two seasons by 25.66%and 262.10%,respectively.Furthermore,the organic-inorganic composite materials increased the organic matter content in red soil by 30.97%on average in the two seasons,and they increased the nitrogen,phosphorus,and potassium content in the soil before sowing and after harvest in the two seasons.Comprehensively,the organic-inorganic composite materials demonstrate a significant improvement effect on red soil in dryland by increasing the soil pH and modulating the soil nutrient structure,thus boosting the productivity of red soil in dryland.
