腐植酸类肥料是一种多功能和含有丰富有机碳的优良有机矿物肥料,据有关资料报道和我所1975—1976年对泥炭制成的腐铵试验结果表明,它具有改良土壤理化性状;刺激作物生长发育等良好作用。为了广辟有机肥源,加速红壤改良熟化。我所从1980年开始,根据全国腐肥会议精神,参照农业部统一试验方案,参与协作点试验。现将两年田间定位试验研究结果初报如下: 一、试验设计和供试材料本试验设在本所第四纪红色粘土发育的
Humic acid fertilizer is a multifunctional and organic fertilizer rich in organic carbon fertilizers, according to the information reported and my 1975-1976 peat made of the test results showed that peat, it has to improve soil physical and chemical properties; stimulus Crop growth and development and other good effects. In order to broaden the source of organic fertilizer, accelerated red soil improvement and aging. Since 1980, according to the spirit of the National Conference on Decomposing Fertilizers, we have taken part in the pilot program of the Ministry of Agriculture in line with the unified experimental plan of the Ministry of Agriculture. Now two years field experiment results are as follows: First, the experimental design and test materials This test is located in the Quaternary red clay development
