摘要
以冀绿9239为试验材料,采用测土配方施肥推荐的"3414"统一标准进行试验设计,在山西绿豆主产区怀仁县开展肥效试验。结果表明,在试验地基础肥力条件下绿豆产量为975.8 kg/hm2,相对产量为75.1%,缺氮、缺磷、缺钾条件下相对产量分别为84.7%,84.3%和90.1%。氮、磷、钾配合施用能够增加绿豆的单株荚数、单株产量、百粒质量及单位面积产量。根据产量结果拟合方程及绿豆、肥料市场价格得出,当N,P2O5,K2O使用量分别为94.12,112.57,96.25 kg/hm2时,最佳经济产量为1 253.18 kg/hm2,三要素比例为1∶1.19∶1.02。单因素肥效分析显示,各肥料施用量与绿豆产量之间均表现出典型的抛物线特征,N施用量为103.33 kg/hm2时,获得最佳经济产量1 295.07 kg/hm2;P2O5施用量为117.26 kg/hm2时,获得最佳经济产量1 257.24 kg/hm2;K2O施用量为90.41 kg/hm2时,获得最佳经济产量1 278.11 kg/hm2。
Taking Jilyu 9239 as test material, we carried out fertilizer efficiency trials using fertilization unified recommended ＂3414＂ design in Huairen county which was a major mung bean-producing regions of Shanxi province. The results showed that while no fertilizer was applied, the mung bean yield was 975.8 kg/hm2, and the relative yield was 75.1%. The three treatments, lack of nitrogen,phosphorus and potassium fertilizer respectively, possessed the relative yields of 84.7%,84.3% and 90.1%. Combined application of nitrogen, phosphorus and potassium fertilizer could increase the number pods per plant, the seed number per pod, 100-seed weight and the yield per unit area of mung bean. According to the yield fitting equation and market price of mung bean and fertilizers, the most economic fertilization regime was N 94.12 kg/hm2, P2O5112.57 kg/hm2, and K2 O 96.25 kg/hm2, with a yield of 1 253.18 kg/hm2. At this rate of fertilization, N∶P2O5∶K2O was 1∶1.19∶1.02. Univariate analysis showed that among nitrogen fertilizer amount and yield of mung bean showed the typical characteristics of the parabola. While the most economic yields was 1 295.07 kg/hm2, amount of applied N was 103.33 kg/hm2. While the most economic yields was 1 257.24 kg/hm2, amount of applied P2O5 was 117.26 kg/hm2. While the most economic yields was 1 278.11 kg/hm2, amount of applied K2 O was 90.41 kg/hm2.
