通过设置常规施肥、配方施肥+有机肥、配方施肥+秸秆还田、中量化肥4种不同施肥方式的定位小区监测试验,研究浙北嘉兴平原新造农田土壤培肥方式对耕地肥力与作物产量的影响。结果表明,由于新造农田地力差,各施肥处理均能有效提高土壤肥力,其中配方施肥+有机肥处理和配方施肥+秸秆还田处理对提高土壤综合肥力和增产效果明显,特别是对春季作物增产效果更好。
Through setting up four monitoring plots of conventional fertilization, formula fertilization + organic manure, formula fertilization + straw returning and middle fertilizer in different fertilization modes, this paper studied the effect of fertilization mode on soil fertility and crop yield of new farmland in Jiaxing Plain of North Zhejiang influences. The results showed that all fertilization treatments could effectively increase soil fertility due to poor soil fertility of new farmland. Fertilizer + organic manure and formula fertilization + straw returning were effective in improving soil comprehensive fertility and yield increase, especially for spring crop yield increase Better results.
