研究结果表明：胡椒嫩叶出鞘后30～35d完全稳定，以带花穗、位于植株中部、阳面、短枝上的叶片作为采样叶；1d中除12：00～14：00外，其它时间均可采样；1a中以4月和10月作为采样时间。拟定4月和10月的营养指标，4月份适宜范围为：N2．7％～3．1％、P0．17％～0．21％、K1．6％～2．0％、Ca1．1％～1．3％、Mg0．23％～0．30％；10月份为：N2．9％～3．5％、P0．16％～0．20％、K1．8％～2．5％、Ca1．0％～1．2％、Mg0．27％～0．31％．范围下限为临界值每公顷需摄取养分N、P、K、Ca、Mg与国外资料比较大体相符。经生产验证．诊断施肥的产量显著或极显著高于同类未经诊断的，一般可提高产量20％～30％．平均可达4260kg／hm2，还可节省原过磷酸钙用量的65％以上。
The results showed that the leaves of pepper were completely stable after 30-35 days of emergence, and the leaves with spikes and the leaves on the middle and the shoots and short branches were used as the sampling leaves. During the first day except 12: 00-14: 00, Can be sampled; 1a in April and October as the sampling time. In April and October to develop nutritional indicators, in April the appropriate range: N2.7% ~ 3.1%, P0.17% ~ 0.21%, K1.6% ~ 2.0%, Ca1.1% ~ 1.3%, Mg0.23% ~ 0.30%; October: N2.9% ~ 3.5%, P0.16% ~ 0.20%, K1.8% ~ 2.5% Ca1.0% ~ 1.2%, Mg0.27% ~ 0.31%. The lower limit of the range is the critical nutrient value required per hectare N, P, K, Ca, Mg is generally in accordance with foreign data. Production verified. The yield of the diagnostic fertilization is significantly or very significantly higher than that of the same type of non-diagnosed, generally increase the yield of 20% to 30%. An average of up to 4260kg / hm2, but also can save more than 65% of the original amount of superphosphate.
