Micronutrients Are Actually No Small Thing

作者：管理日期：2018-12-04类别：Blogs

Just because the plant uses them in smaller quantities than macronutrients, doesn’t mean that micronutrients aren’t essential for crop production.

What are micronutrients?
微量营养素包括锌，铁，锰，硼，氯，铜和钼，通常报道标准土壤试验。钴，钒，钠和硅也是微量营养素，但很少被发现缺乏，并且正常植物生长需要额外的营养素。

pH matters
Micronutrients tend to be more available when the pH is 7 to 7.5, which is slightly alkaline, while macronutrients prefer a pH between 6.2 to 7.0, which is slightly acidic. A pH of 7.0 in neutral on the pH scale of 0 to 14. Understanding each micronutrient mineral element’s function in plant growth will help you to determine the right nutrient applications and to diagnosis any potential crop production problems.

1. Zinc (Zn)
锌在植物和土壤中被认为是不动的，并且是玉米和大豆生产中最常用的微量营养素。植物的蛋白质，酶形成和细胞壁完整性是重要的。在土壤中具有高钙水平的锌系数可能存在问题，使锌无法被植物吸收。此外，高磷水平可导致锌不被植物生长所需的吸收，导致缺锌症状。这些症状包括玉米叶上的白色条带或条纹，并在大豆中缩短了尤基。您的收益率可能因缺乏土壤锌而受到影响。

2. Iron (Fe)
铁是一种固定营养素。它在光合作用和植物呼吸中起着至关重要的作用，并且还需要大豆中的氮固定。铁缺乏症状包括大豆叶的间肺源，称为铁萎黄，通常在7.5至8.3的高pH下发现。在严重的铁萎黄病例中，可能发生植物死亡。为了纠正短缺，您可以在种植之前将铁肥施加到土壤中。叶片对生长植物的叶面应用可以帮助解决变色，但可能只是需要重复应用的临时修复。

3.锰（Mn）
Manganese is mobile in the soil but immobile within plant tissue. The primary function of manganese is to be a activator of plant growth enzymes. It also helps in chlorophyll formation. Manganese deficiency symptoms can often be confused with iron chlorosis, which is another reason why soil testing is so critical. Soil pH is generally higher in the areas where the yellowing leaf symptoms develop. Adding manganese to areas that have low soil levels of it should see a yield response—cut areas of soil and eroding soil sidehills often respond well to manganese applications.

4.硼（b）
Boron helps with cell wall formation and regulates plant metabolism. It is a mobile element and can be leached from the soil with rainfall, making it unavailable to your plants. But, boron is also immobile once introduced into plants—plant availability of born decreases in dry environments and when soil pH is high. Boron deficiencies can be identified by malformed and discolored young leaves and stunted plants.

5. Chlorine (Cl)
氯气是一种非常移动元素的函数s to regulate osmosis and charge compensation (that is, the movement of cations, atoms and small molecules in and out of plant cells as part of normal cell activity). While chlorine requirements are small to maintain proper plant growth, concentrations inside plants are high, similar to macronutrient concentrations. Many agronomists speculate that most of the chlorine used by plants comes from rain, soil and air pollution. Overall, you may find that you have more problems of toxicity from too much chlorine rather than a deficiency—symptoms include bronzing leaves followed by wilting and chlorosis.

6. Copper (Cu)
Copper is immobile in both soil and plants. It assists plants in protein and enzyme production and is rarely in short supply. Like chlorine, you should be careful to avoid the possibility of copper toxicity when adding copper to a fertility program. Copper deficiency symptoms are dark, blue-green leaves and stunted plant growth followed by young seedling death.

7. Molybdenum (Mo)
植物在最小量的任何微量营养素中需要钼，以帮助控制酶形成的金属成分。它还能够有效地使用植物来使用氮。钼缺乏症状倾向于模仿氮素短缺。缺乏活力的黄色，缺乏活力的植物在霉菌的土壤中是常见的。钼是在植物中的不动，土壤中有点移动。

钴（CO）镍（Ni）是植物组织中发现的另外两个微量营养素元素，但它们需要通过肥料应用补充它们。

测试微量营养素缺陷
植物组织试验应伴随诊断以验证缺陷。当然，可靠的土壤测试也可以证实，确实存在微量营养素缺乏，需要添加肥料以纠正短缺。

Correcting micronutrient deficiencies

如果您和您的农学家确定您的田地具有确认的微量营养素缺乏，根据发现症状时，您最有可能使用土壤施肥的微量营养素元素短缺。它通常是最有效的方法，通常比叶面应用肥料应用更便宜。始终务必阅读并遵循标签使用说明。
