浙西南山区旱地多熟间套作不同培肥方法的效果研究

Effects of fertilization modes on output of multiple intercropping and soil fertility on dryland in southwest mountain area in Zhejiang

通过采取一年三熟间套作三年定位培肥的方法,设三季栏肥还地、三季秸秆+冬绿肥还地、三季秸秆还地、冬绿肥还地及主施化肥(对照)等5个处理,进行不同培肥方法对一年三熟间套作物增产效果和土质改良效果的研究。试验结果表明:栏肥还地对各熟作物增产效果显著,并有效改善了土壤肥力,其次为三季秸秆+冬绿肥>三季秸秆>冬绿肥>对照。

The test was carried out for three years with 3 - seasons multiple cropping to study the effects of different fertilization modes on yield increase and soil improvement. Five treatments were designed in the test, i.e., 3-seasons yard manure, 3-seasons stalk ＋ winter green manure crop, 3 - seasons stalk, winter green manure crop and chemical fertilizer. The results showed that yard manure was the best mode to increase the output of crops and to improve the soil fertility; the second was 3-seasons stalk ＋ winter green manure crop; the third was 3-seasons stalk; the fourth was winter green manure crop, and the fifth was chemical fertilizer.
