辣椒幼苗对肥水十分敏感,肥料多时易形成徒长苗,子叶脱落,移栽后缓苗期长。施肥过多还易出现肥害,使根系受损,严重时导致幼苗蔫萎死亡。缺肥时易形成老化苗,新根少,茎细节短,开花结果迟且易早衰。水分多时,幼茎纤弱,抗性差,易发猝倒病。苗期受旱,叶片下垂,叶柄弯曲,花芽分化受到抑制。只有科学地用肥控水,才能培育壮苗。在苗期的水肥管理上,主要抓好以下几个技术环节。首先,要看苗施肥,带肥移栽。苗期追肥一要看幼苗的长势,二要看苗床的肥力情况,三要看辣椒品种熟期。早熟品种在肥力中等 Pepper seedlings are very sensitive to fertilizer, fertilizers often easy to form leggy seedlings, cotyledons off, slow seedlings after transplanting period. Excessive fertilization is also prone to fertilizer damage, so that the root damage, serious lead to seedlings wilt death. Aging lack of easy to form aging seedlings, less new roots, stems short details, late flowering and easy premature senility. Moisture, young stems weak, poor resistance, prone to damping off disease. Seedling drought, sagging leaves, petiole bending, flower bud differentiation was inhibited. Only by scientific control of fertilizers in order to cultivate strong seedlings. Water and fertilizer management in the seedling stage, the main grasp of the following several technical aspects. First of all, depends on seedling fertilizer, transplanting with fat. Seedling top dressing depends on the growth of seedlings, two depends on the fertility of seedbed, three to see the ripening varieties of pepper. Premature varieties are medium fertility
