种辣椒施多少肥合适内容摘要:
2、 公斤,钙镁磷肥 50 公斤左右,尿素 1525 公斤,硫酸钾或氯化钾 1020 公斤(或草木灰 200 公斤)。 具体施肥量依据土壤肥力增减。 其中钙镁磷肥迟效,在土壤中移动性差,又极易被土壤固定,应全部作基肥,并集中沟施。 尿素易烧根又容易流失只能少量 (一般 5 公斤亩)作基肥。 钾肥也很容易流失,而且辣椒结果期大量吸收钾,钾肥可促进果实膨大,所以钾肥主要在结果期作追肥用。 复合肥多用作基肥。 若是地膜覆盖栽培,总量的 80以上作基肥;不盖地膜的保肥性好的黏性土5060作基肥,漏肥的沙性土 3040作基肥。 除氮磷钾外,辣椒还需要多种营养元素。 农家有机肥养分完全,还可以改良土壤,所以种辣椒施用农家肥好。 没有农家肥的,可购买生物有机肥,它所含的活性菌有固氮、解磷、解钾作用,即把空气中的游离氮固定于土壤中,把土壤中作物不能利用的磷、钾转化为可利用态,肥效高,无污染,施用后作物病虫害减少,产量和品质提高,如果完全用化肥种辣椒,除常规施肥外,还需叶面喷肥,主要是补充它需要的硼、锌、铁、铜等微量元素,可选用高产宝、喷施宝、植物动力 2003、广增素等叶面肥,喷施 3 次,一般增产 15以上。 专利查询。种辣椒施多少肥合适
