摘要: 通过露天大田试验,按随机区组设计,通过设置11个肥料处理组N0P0K0、N0P2K2、N0.5P2K2、N1P2K2、N1.5P2K2、N2P2K2、N2.5P2K2、N3P2K2、N2P0K2、N2P2K0、MN2P2K2,每个处理重复3次,研究不同施肥处理对豆角产量等指标的影响。结果表明,当磷、钾肥投入相同,以N1.5为分界点,产量、净收益和豆角/地表植株呈现两段式递增趋势,当N∈(1.5,2.5),施氮量与豆角/地表植株呈负相关;当N∈(2.5,3],施氮量与豆角/地表植株正相关;MN2P2K2时,产量、净收益和豆角/地表植株达到最大。氮肥对豆角产量影响最大,磷、钾肥其次;有机肥+无机肥配施豆角增产最大。

Abstract: Using field cultivation method, the experiment was laid out in a randomized complete block design (RCBD) with 11 treatments replicated 3 times, including N0P0K0, N0P2K2, N0.5P2K2, N1P2K2, N1.5P2K2,N2P2K2, N2.5P2K2, N3P2K2, N2P0K2, N2P2K0, MN2P2K2, to compare the differences in cowpea yield and other indexes. The results showed that with the same investment of phosphate and potash fertilizer, yield, net income and cowpea/straws(c/s) showed increasing tendencies divided by N1.5. When N∈(1.5,2.5), nitrogen rate is negatively correlated with c/s. When N∈(2.5,3], nitrogen rate was positively correlated with c/s. The yield, net income and c/s reached maximum as the MN2P2K2 treatment. The experiment proved that the most influential factor of cowpea yield was nitrogen, phosphate and potash fertilizer were not obvious. The application of organic fertilizer and chemical fertilizer increased cowpea yield most influentially.

Key words: cowpea, yield, nitrogen, organic fertilizer
