Effect Of Different Fertilization On The Yield And Quality Of Schisandra Chinensis

The research of Schisandra chinensis was conducted on the dark brown forest soil surrounding hillsides in Shangzhi, Heilongjiang Province. No fertilizer (CK) was set as the control, the formula fertilization (B), formula fertilization + peat (C), formula fertilization + peat + Zn(D), formula fertilization + Zn (E), respectively. Through analysis of soil physical and chemical properties and schizandrol A, the effects of fertilization and harvest time on the yield and quality of schisandra chinensis were carefully discussed.Experimental results showed that peat could promote soil water, bulk density, nitrogen, available phosphorus, potassium and other factors such as soil fertility. Peat had a strong ability to improve soil physical and chemical properties.It was especially important to dress enough N and K at the first growth peak period and N and P at the stage of fruit swelling. Soil urease activity reached significant difference among all treatments. Soil peroxidase activity only of the peat treatment reached significant difference between the control treatments.The content of soil organic matter of formula fertilization + peat (C) treatment reached a significantly difference with the blank treatment, and so did formula fertilization (B) treatment The enzyme activity of formula fertilization + peat (C) treatment reached a significantly difference with the blank treatment, and so did formula fertilization (B) treatmentBoth fertilization of peat and Zn could raise the yield and quality of schisandra chinensis, especially peat + Zn. The yield of the treatment of formula fertilizer + peat + Zn(D) increased by 71.3% to the control, and by 25.70% to the treatment of formula fertilization (B).According to the schisandra chinensis yield and Schizandrol A content, the best harvest time of schisandra chinensis in Shangzhi, Heilongjiang Province was determined on August 21.According to correlation analysis of data, soil urease activity, highly active organic matter and schisandra chinensis production reached a significant positive correlation. Urease activity showed a positive correlation with soil organic matter significantly. Soil bulk density and soil organic matter had shown a negative correlation significantly.
