氮、磷、钾,过量使用!后果这么可怕!
有机肥农化大全

一直以来,在很多农民的观念里,就是化肥撒的越多,农作物生长的就越快,收成就会越好。其实则不然,有时往往还会适得其反。过量使用化肥还会造成很多危害。今天就和大家一起来具体分析一下大量元素氮磷钾肥料的作用及用量过度会产生什么危害。

氮的作用和过量危害

1、氮的作用

植株缺氮色绿浅,基部老叶色发黄,干燥之后褐色现!果小果少果皮硬,定是果树缺少氮!即能组成叶绿素,又要组成核苷酸!

氮的作用:氮肥是农业生产中需要量最大的化肥品种,它对提高作物产量、改善农产品的质量有重要作用。它是植物体内氨基酸的组成部分、是构成蛋白质的成分,也是植物进行光合作用起决定作用的叶绿素的组成部分。氮还能帮助作物分殖。施用氮肥不仅能提高农产品的产量,还能提高农产品的质量。

2、氮过多的危害:阻碍作物生长产生毒性亚硝酸盐

氮肥是农业生产中需要量最大的化肥品种,它对提高作物产量、改善农产品质量有重要作用。但是,如果供应过多,则使作物贪青晚熟,生长期延长,主要表现在细胞壁薄,植株柔软,易受机械损伤(倒伏)和病害侵袭(比如大麦褐锈病、小麦赤霉病、水稻褐斑病)。同时,大量施用氮肥还会使棉花蕾铃稀少易脱落、甜菜块根产糖率下降、纤维作物产量减少、纤维品质降低等。
  

需特别注意的是,氮肥过量所生产的“氮肥蔬菜”,其茎叶等可食部分,均被硝酸盐严重污染,会使蔬菜中的硝酸盐含量成倍增加,进而转化为亚硝酸盐,亚硝酸盐是-种剧毒物质,它能引起人体细胞缺氧,并能诱发癌症,危害极大。

磷的作用和过量危害

1、磷的作用

庄稼缺磷很麻烦,植株深绿不难看,红色紫色也出现。干燥之后色绿暗,茎节同样细而短!基部叶片色变黄,开花时间迟几天,结籽变小不饱满!

磷的作用:既可以增加农作物的产量,又可以提升农作物的品质。能够加速谷类作物的成长,促使籽粒大而饱满,促使蔬菜,瓜果,棉花等果树的开花结果,提高结果率;增加水果,甘蔗等的含糖量,也能增加油菜籽的含油量。

磷是植物细胞核的重要成分,它对细胞分裂和植物各器官组织的分化发育特别是开花结实具有重要作用,是植物体内生理代谢活动不可缺少的一种元素。磷在植物体内主要集中在植物的种子中,种子中贮备较多的磷,从而有利于幼苗初期的健康生长。磷对提高植物的抗药性、抗寒性和抗旱能力也有良好的作用。磷还具有促进根系发育的作用,特别是促进侧根和细根的发育。

2、磷过量的危害 :造成土壤缺硫作物失绿黄化

施用普通过磷酸钙不仅能为作物提供磷营养,而且还可使作物获得硫营养,但因其含磷量低,含副成分多,为此生产中常用重过磷酸钙这一磷肥品种。重过磷酸钙中不含硫酸钙等杂质,从而使磷的含量大大提高,成为高浓度磷肥。因此,常年施用重过磷酸钙自然就会出现缺硫问题。 作物缺硫症状与缺氮十分相似,主要特征是叶片失绿黄化,但从细微的表现看,它们是有区别的。缺氮的症状是首先从下部老叶开始,而缺硫的症状是从上部新叶开始,导致叶片是绿黄化。

钾的作用和过量危害

1、钾的作用

庄稼缺钾要补上,叶片边沿先发黄,严重叶缘灼烧状,双子叶脉间失绿,营养运输跟不上。有机化物不参与,细胞液中离子状,多重酶的活化剂,代谢过程作用强!氮、磷、钾,过量使用!后果竟然这么可怕!

作用:施用钾肥能够促进作物的光合作用,促进作物结果和提高作物的抗寒、抗病能力,从而提高农业产量。钾元素在植物体内以游离钾离子形式存在,它能促进碳水化合物和氮的代谢;控制和调节各种矿物营养元素的活性;活化各种酶的活动;控制养分和水的输送;保持细胞的内压,从而防止植物枯萎。

2、钾过剩 :影响作物生长破坏土壤结构

钾肥是供植物生长需要的钾素养分的肥料,适量施用钾肥,能使谷物籽粒饱满,促使土豆,薯类等块根增大,水果等增加糖分,使稻麦等禾本科作物分蘖增多,并能使植物茎根粗壮,不易倒伏,增强抗旱、抗寒、抗病能力。钾肥虽然好处多,但用量不是越多越好,过量施用会给农作物带来不良影响:

①造成农作物对镁和钙的吸收量下降,引起叶菜“腐心病”、苹果“苦痘病”等多种病害的发生;

②对农作物的生长有阻碍作用,导致作物容易出现倒伏等症状;

③造成部分地块有害金属和有害病菌超标,破坏土壤中的营养结构和平衡,导致土壤性状恶化,及水体污染;

④会降低农作物的生产情况,严重减弱农作物的生产能力,降低产量。

TE (Trace Element)
Micro Nutrients

Trace elements are administered to the plant in various nutrients, including boron (B), molybdenum (Mo), manganese (Mn), copper (Cu), zinc (Zn) and iron (Fe). The combination of these trace elements and main elements is important to achieve continuous growth and healthy growth of plants.

Amino acids chelated trace elements improves absorption through the roots, increase crop resistance to adverse condition (drought, salinity, disease), and improves flavor, color, firmness as well as preservation of fruit. Also, it helps the plant to produce its own protein easier, saving energy required to produce amino acids, benefit formation of the proteins and plant cells. In participate in the development of different enzymes, hormones, promotion of photosynthesis, improvement of fertility and cell extension and the development of leaf green and strength of cell membranes.

Humic acid improves soil composition by supplementing and rejuvenating it, and in doing so, improves availability, mobility, and management of nutrients in the substrate, and improves water retention. Humic acid actively allows for nutrients and minerals such as calcium, iron, magnesium, zinc, and manganese to be absorbed readily, stimulating improved plant growth and healthy roots. This works in any type of grow and provides benefits during all stages, from the seedling that just sprouted to mature plants.

Application Rate

For foliar spray : 1g per 1 – 1.50 L of water.
Apply frequency : Weekly / 10-15 days

Plant can directly absorb through leaves surface. In a few hours after foliar spray, the plants starting to absorb the nutrients, in 1 to 2 days it will almost completely absorbed.

For soil drenching : 2g per 1 – 1.50 L of water.
Apply frequency : Weekly / 10-15 days

FULVIC ACIDS have a close relationship with humic acid. It is a humic material that is light yellow to brown, but unlike humic acid, is soluble at all pH levels - acidic and alkaline. Its molecular weight is lower than that of humic acid since it has less carbon but a higher oxygen content. The lower molecular weight gives fulvic acid the ability to cross the membranes of plant cells so it can easily pe*****te leaves, making it an efficient foliar spray that can provide nutrients to plants quickly. But you can also use it via irrigation by mixing it with your regular nutrient solution.

Humic and fulvic acids are excellent to use together with a well-balanced nutritional program. They benefit your plants through-out all stages of growth and with the help of humic and fulvic acids, you’ll improve soil composition and chelating ability, enhancing nutrient uptake. And, with increased vitality and root development, you can ensure that your plants are getting the most out of their available nutrients. There are several popular products in the marketplace that provide these benefits. Compare their ingredients, percentages and cost and choose the product that best meets your needs.

化学肥料通常分为常量元素肥料和微量元素肥料两类。

哪些是常量元素 肥料呢?常量元素肥料是庄稼吸收消耗数量大的肥料,象氮肥、磷肥、钾肥、 钙肥、镁肥、硫肥都属这类肥料。
微量元素肥料,通常简称为微肥。是指含有微量营养元素的肥料,庄稼 吸收消耗量少(相对于常量元素肥料而言)。作物对微量元素需要量虽然很 少,但是,它们同常量元素一样,对作物是同等重要的,不可互相代替。微 肥的施用,要在氮、磷、钾肥的基础上才能发挥其肥效。同时,在不同的氮、 磷、钾水平下,作物对微量元索的反应也不相同。一般说来,低产土壤容易 出现缺乏微量元素的情况;高产土壤,随着产量水平的不断提高,作物对微 量元素的需要也会相应增高。因此,必须补施微肥,但若企图减少大量元素 肥料的施用量,而只靠增施微肥来获得高产,也是错误的。

微肥是经过大量的科学试验与研究,已经证实具有一定生物学意义的, 植物正常生长发育不可缺少的那些微量营养元素,在农业上作为肥料施用的 化工产品,象硼肥、锌肥、锰肥、钼肥、铜肥、铁肥、钴肥都属于微肥。

这些微量元素占作物体干重的百分数大致是:锰 0.05%、铁 0.02%、锌 0.01%、硼 0.005%、铜 0.001%、钼 0.0001%。土壤中任何一种速效态微量元素供应不足,作物就会出现特殊的症状,产量减少,品质下降,甚至收成无望。 也许有人要问,既然微肥这么重要,而在生产中并没有施用微肥。
