Effects of Organic Manure Made from the Gibberellin Producing Residue on the Biologic Character of Plant

The effects of organic manure made from the gibberellin producing residue on plants and soil were studied by experiments in the field,and the major findings were summarized as follows:(1) The yield of rice,tea,orange,vegetable,sweet pea had increased,and the quality of fruit had improved,the florescence of sweet pea had prolonged also through the combined application of organic manure and chemical fertilizers;(2) The contents of the organic matter,the available nitrogen,phosphorus and potassium in the soil applied with organic manure and fertilizer were signifiantly higher than those in the soil applied with only chemical fertilizers.However,the two kinds of the fertilization had little effect on the pH value.It must be point out that the two kinds of the fertilization were at the same application amount of nitrogen,phosphorus,and potash.
