摘 要:夏花生重施前茬肥比重施后茬肥增产十分显著。即在冬小麦、夏玉米和夏花生两年四茬作物,施肥总量相同的条件下,常规施肥的冬小麦、夏玉米和夏花生,比重施后茬花生肥的分别增产8.00%、6.49%和10.48%;重施前茬粮食肥的比重施后茬花生肥的依次增产19.47%、25.04%和18.76%。粮食和花生混合总产,常规施肥和重施前茬肥,分别比重施后茬肥增产8.18%和18.63%;纯增效益分别增加8.62%和20.18%。The yield increment of summer peanut with higher level of fertilizer application to preceding cereal crops (winter wheat, summer maize et al.) was very significant than that of summer peanut, as an ensuing crop, with the same level of fertilizer application. Under the same level of total fertilizer application to four-preceding crops in past two years, yield of the preceding crops with common level fertilizer was with 8.00%, 6.49% and 10.48% higher than that of summer peanut (as an ensuring crop) with higher level fertilizer application. Yield of the preceding cereal crops with higher level fertilizer was with 19.47%, 25.04% and 18.76% higher than that of summer peanut as an ensuring crop with higher level fertilizer. Total production of cereal crops and summer peanut, under the common level fertilizer application and higher level fertilizer application to the preceding crops, was with 8.18% and 18.63% higher than that of with higher level fertilizer application to ensuring crops, while the net income was increased by 8.62% and 20.13%, respectively.
