    二、功能與主治

     

    本品為高效螯合鐵肥,主要用于防治植物缺鐵造成的黃化病(也稱黃葉病);也可用于正常植物補鐵,可使植物生長更旺盛,增加產量和提高果實品質;對于長期施用普通化肥造成的土壤板結、肥力下降有明顯改善作用。
     

    三、用法與用量

     

    花卉:

    第一次每畝施用量為300克,按1克本品兌0.5升水的比例,用清水將本品完全溶解后,進行葉面噴施花卉。 豆科植物:一個結果周期施用兩次,第一次為新葉萌芽期,第二次為花落時;第一次每畝施用量為250克,第二次追肥用量減半,按1克本品兌0.5升水的比例,用清水將本品完全溶解后,進行葉面噴施。觀賞植物:參照豆科植物用法和一次用量,在新葉萌芽期施用一次即可。

    果樹:

    一個結果周期施用兩次,第一次為新葉萌芽期,第二次為花落時。第一次每株施用量為30克,第二次追肥用量減半;按1克本品兌0.5升水的比例,然后施于根系土壤中,盡量使根系均勻受肥。

    果樹及花草也可根據以下推薦量使用:

    柑橘…………20克/棵 蘋果…………20克/棵 桃子…………20克/棵 梨樹…………20克/棵 柚子…………20克/棵 檸檬…………20克/棵、獼猴桃等果樹………20克/棵 葡萄、草莓等…………100克/100米排溝 菊花、天蘭葵…………50克/10平方米 杜鵑、玫瑰花、百合等…………50克/叢

    其他農作物參照上述使用方法使用,一般來講,使用量可根據作物大小和鐵缺乏的程度,適當增加使用量,最大用量50克/顆樹,如果撒施入土壤蓋土后及時澆水效果最佳。

     

    四、產品特色

    有機高效螯合鐵肥是近年來新興的土壤補鐵微量肥料,目前,市面上主要有EDTA鐵、DTPA鐵、EDDHA鐵,氨基酸螯合鐵,檸檬酸鐵、富馬酸亞鐵及無機硫酸亞鐵等。但因其吸收率、營養性、PH值實用范圍、價值等的不同而各有其特點。傳統上施用的無機鹽類,不僅由于其性質的不穩定而造成使用效能底下,更為重要的是對土壤具有破壞性作用,不利于綠色農業和可持續性發展。因而對于可溶性的有機高效螯合鐵肥的使用成為當務之急。 EDDHA鐵雖然價格高,但因其PH值實用范圍廣,吸收率高,在國內主要運用于經濟作物、花卉等高檔作物中,而在歐美發達國家用量較普遍。  

     

     

     

     

    EDDHA-Fe is high active chelated iron, and is more easily to be absorbed by plants.Its assimilation effect is far better than common EDTA chelated iron, and hundreds times the traditional iron fertilizer.
    The fertilizer can be well absorbed by plants when the soil PH is 4.5-11(the higher the PH is, the more obvious the advantage of EDDHA-Fe to EDTA-Fe and ferrous sulphate is). The implementation effect is better when water and basic fertilizer are adequate for plants. The lacking of one minerals may result in lacking of another related microelement fertilizer, so you should make sure what is needed before you apply fertilizers, EDDHA-Fe can be mingled with other chelated microelement fertilizers such as EDTA-Zn, EDTA-Mg.


    Spray on Foliage:
    It is ultra efficient when you spray EDDHA-Fe to the leaves, in 1000-1500 diluted concentration, once a week, spray 2 or 3 times at a time(the spray frequency depends on the degree of lacking of iron).
    The best way to apply EDDHA-Fe is irrigating the root by water solution of the EDDHA-Fe(consistency 0.1%). If the soil is hardened, cultivate the soil before irrigating.
    For the north where flood irrigation is commonly used, EDDHA-Fe can be distributed into the water to irrigate the soil, once 500-1000g per Chinese acre.
    For fruit trees or shrub, the made-up solution can be injected into the roots of the plants.


    Soil application rates:
    Orange……20g/plant
    Apple, Peach, Pear……20g/plant
    Grapes, strawberry……100g/100 meters row
    Chrysanthemum, geranium……50g/10 square meters
    Cuckoo, rose, lily……50g/bush
    The herein is recommending dosage, the actual dosage should depend on the size of plants and the lack of iron, the effect is better if the fertilizer is distributed into the soil and watered after earth up.
    Make hydroponics liquor:
    Add EDDHA-Fe 15-20g to the water to make up nutrient solution.


    Attentions:
    Keep in a cool and dry place.
    It can be mingled with most fertilizer and agricultural chemical.
    The effect is better when both watering the soil and spray the leaves with the fertilizer.
    The spray should be before 9 am.or after 4 pm.,if it rains 4 hours after spray, spray again.
