- 摘要:
- 2012年3月至2013年9月，在邯郸市成安县黄冠梨园进行生草和覆盖处理，以12～13年树龄的黄冠梨为试材，以清耕为对照，对其土壤微生物性状进行测定。结果表明：在0～20 cm土层内，秸秆覆盖和梨园生草可以显著增加表层土壤细菌和真菌数量，但对20～40 cm土层内土壤细菌、真菌数量影响不显著。在0～40 cm土层内，梨园生草可以显著增加土壤放线菌数量，而秸秆覆盖土壤放线菌数量增加不显著。
- Abstract:
- From March 2012 to September 2013，the soil microbial properties were studied in 12-13 years old Huangguan-pear orchard of Cheng,an county.In this orchard，grassing and mulching were treatments and clean tillage was control.The results showed that within 0-20 cm soil layer，grassing and mulching could significantly increase the number of soil bacteria and fungi，but within 20-40 cm soil layer，the number of soil bacteria and fungi was not significantly increased.Within 0-40 cm soil layer，the numbers of soil actinomycetes were significantly increased in the grassing treatment and were not significantly increased in the mulching treatment.
