据《中国南方果树》2013年第6期《生物炭对酸性红壤改良及枳砧纽荷尔脐橙苗生长的影响》(作者张祥等)报道,采用盆栽试验,以0.1%、2%生物炭量及其与化肥配合施于酸性红壤中,研究了生物炭对酸性红壤理化性质以及枳砧纽荷尔脐橙幼苗生长的影响。结果表明,施生物炭对酸性红壤理化性质有明显影响,pH值、有机碳含量和速效钾含量均有显著改变,如pH值提高0.45～0.96个单位,有机碳含量提高1.2～3.0倍,速效钾含量提高2.0～4.6倍,同时,保肥能力增强。红壤施生物炭 According to “China Southern Fruit Tree” 2013 the sixth period “biochar on the improvement of acid red soil and Trifoliatense Newhall navel seedlings growth” (by Zhang Xiang, etc.) reported that the pot experiment to 0.1%, 2% biochar Amount and its application with fertilizers in acid red soils, the effects of biochar on physical and chemical properties of acid red soil and the growth of Newhall navel orange seedlings were studied. The results showed that biochar had a significant effect on physical and chemical properties of acid red soil, pH value, organic carbon content and available potassium content were significantly changed, such as pH value increased 0.45 to 0.96 units, organic carbon content increased 1.2 to 3.0 times, quick effect Potassium content increased by 2.0 to 4.6 times, at the same time, enhance fattening ability.
