干制辣椒土壤养分调查及配方施肥

Analysis of Soil Nutrients and formula Fertilization in Hot Pepper for Fruit Drying

云南省砚山县气候温和,降雨较丰富,土壤肥力普遍较高,适宜干制辣椒种植,但施肥上主要表现为氮、磷肥用量偏高,钾肥用量不足,复合(混)肥和单质肥配合施用欠妥,农家肥使用量偏低,致使氮、磷、钾投入失衡。根据调查分析和配方施肥要求,建议当地施肥应遵循"减氮、减磷、增钾"的原则,调整复合肥配比,减少单质肥的使用,增加有机肥施用量,一般应不低于3000kg/667m2,降低因施肥搭配不当造成的养分失衡和浪费。

This investigation was conducted on fertilizer application situation in hot pepper cultivation for its fruit drying in Yanshan County of Yunnan. It shows that there are irrational and imbalanced fertilizations of N, P and K in this crop’s production there i.e. more N and P but less K applied than enough, etc. So some suggestions are offered on rational, balanced and economical fertilizations by formula e.g. decreasing N and P, increasing K and organic fertilizers or manure i.e. generally over 45 t per hm2, adjusting and improving fertilization ratio and methods.
