    摘要:

    芸豆的主要产区在东北、华北等地区,氮、磷、钾施肥量不平衡导致芸豆产量较低。为研究芸豆对3种元素的需求规律,探索氮、磷、钾的最佳施肥量及其配比,试验采用三因素二次回归正交旋转设计,研究肥料配施对芸豆产量的影响。结果表明,调整氮、磷、钾施肥量的配比能够显著提高芸豆产量,当N∶P2O5∶K2O=1∶0.55∶0.73(N:69.3 kg/hm2)时,产量达到最大(1714.49 kg/hm2);当N∶P2O5∶K2O=1∶0.55∶0.73(N:69.3 kg/hm2)时,经济效益最佳(11695.02元/hm2)。各肥料对芸豆产量的影响表现为钾>氮>磷。3种元素的增施对芸豆产量的单因素及互作效应均表现为先上升后下降;3种元素的增施对芸豆单株荚数的影响表现为先增长后下降;增施氮、磷肥对百粒重的影响也表现为先上升后下降,在试验范围内增施钾肥则促进百粒重增长;3种元素对芸豆单荚粒数影响不大,证明芸豆单荚粒数是由品种决定的。

    Abstract:

    The main producing area of common bean is in northeast and north of China.The low yield of common bean is caused by unbalance nitrogen,phosphorus and potassium fertilization.In order to explore the needs and the best fertilization of the three elements,quadratic orthogonal regressive rotation design of three factors is applied to study the effect of fertilizer on the yield.The results showed that the yield was increased by adjusting proportioning and dosage of fertilizer,when N∶P2O5∶K2O=1∶0.55∶0.73 (N:69.3 kg/hm2),the yield was the maximum,which was 1714.49 kg/hm2;when N∶P2O5∶K2O=1∶0.55∶0.73 (N:69.3 kg/hm2),the economic benefit was the best with 11695.02 yuan/hm2.The effect of different fertilization on the yield of common bean was potassium>nitrogen>phosphorus.The single factor and the interaction effects of increasing three fertilization on the yield of common bean were increasing first and then decreasing.Pods per plant of common bean increased first and then decreased with increasing the three fertilization.100-seed weight of common bean increased first and then decreased with increasing nitrogen and phosphorus fertilization,and kept increasing with increasing potassium fertilization in the range of the experiment.The effect of the three elements on the seeds per pod of common bean was little,which proved that was self-determined by the cultivar.
