采用草炭和风化炭进行改良盐碱土的盆栽试验。结果表明,施用草炭、风化炭使土壤盐分略有上升,主要使Ca~(2+)和Na~+增加;土壤有机质含量因草炭、风化炭的施用而增加,且与有机物料的用量呈正相关关系;土壤速效氮、速效磷、速效钾含量也均随有机物料的施用而增加。水稻株高、穗长和每穗粒数均有所增加,水稻籽实产量显著提高。
Potted experiment of improving saline-alkali soil with peat and weathered charcoal. The results showed that the application of peat and weathered charcoal increased the soil salinity slightly, mainly increasing the content of Ca2 + and Na +; the content of organic matter in soil increased with the application of peat and weathered carbon, and was positively correlated with the amount of organic material Relationship; soil available nitrogen, available phosphorus, available potassium content also increased with the application of organic materials. Rice plant height, spike length and grain number per spike increased, and the seed yield of rice increased significantly.
