Effects of Combined Application of Organic and Inorganic Fertilizers with Zinc Fertilizer and Lime on Yield and Soil Nutrient Characteristics of Double Cropping Rice
The effects of zinc fertilizer and lime on double-season rice yield and soil nutrient characteristics were evaluated in a typical double-season rice growing area in southern China
in order to propose the best fertilization mode for fertilizing local soil and increasing rice yield. It is equipped with organic fertilizer + inorganic fertilizer (T1)
a total of 4 treatments. The indicators of soil available zinc
alkali nitrogen
available zinc
and pH were determined
and rice yield and soil comprehensive fertility were analyzed. The results showed that: (1) Compared with T1 treatment
T2 treatment significantly increased the 1000-grain weight and seed setting rate of early and late rice
and significantly increased yield by 8.7%. However
the application of lime (T3) in successive years was not conducive to stable yield of rice
significantly reduced 1000-grain weight
and significantly reduced yield in the second year (5.6%). The yield pattern exhibited by the T4 treatment was similar to that of the T3 treatment
and both showed a reduction in production in the second year. (2) The application of zinc fertilizer and lime was beneficial to increasing the content of available phosphorus and alkali nitrogen in soil. Lime could also significantly increase soil pH
but the effective zinc content in T3 and T4 treatments decreased significantly
which was 39.0% and 31.9% lower than that of T1 treatment. However
the application of zinc fertilizer for several years was conducive to the improvement of effective zinc. The effective zinc content of T2 was 22.2% higher than that of T1 treatment. (3) The soil comprehensive fertility was T2 > T4 > T1 > T3
the application of zinc fertilizer was more conducive to improving soil fertility than lime. In summary
the application of zinc fertilizer can significantly increase the soil available nutrient content
and increase production. However
the application of lime in successive years significantly reduced the effective zinc content in the soil. Therefore
lime should be applied cautiously in zinc-deficient soil
and for the long-term application of lime
attention should be paid to the supplement of exogenous zinc fertilizer. Based on comprehensive evaluation of soil nutrient content and rice yield
the fertilization mode of organic-inorganic + zinc fertilizer is the best fertilization mode.
