二、功能与主治

 

本品为高效螯合铁肥,主要用于防治植物缺铁造成的黄化病(也称黄叶病);也可用于正常植物补铁,可使植物生长更旺盛,增加产量和提高果实品质;对于长期施用普通化肥造成的土壤板结、肥力下降有明显改善作用。
 

三、用法与用量

 

花卉:

第一次每亩施用量为300克,按1克本品兑0.5升水的比例,用清水将本品完全溶解后,进行叶面喷施花卉。 豆科植物:一个结果周期施用两次,第一次为新叶萌芽期,第二次为花落时;第一次每亩施用量为250克,第二次追肥用量减半,按1克本品兑0.5升水的比例,用清水将本品完全溶解后,进行叶面喷施。观赏植物:参照豆科植物用法和一次用量,在新叶萌芽期施用一次即可。

果树:

一个结果周期施用两次,第一次为新叶萌芽期,第二次为花落时。第一次每株施用量为30克,第二次追肥用量减半;按1克本品兑0.5升水的比例,然后施于根系土壤中,尽量使根系均匀受肥。

果树及花草也可根据以下推荐量使用:

柑橘…………20克/棵 苹果…………20克/棵 桃子…………20克/棵 梨树…………20克/棵 柚子…………20克/棵 柠檬…………20克/棵、猕猴桃等果树………20克/棵 葡萄、草莓等…………100克/100米排沟 菊花、天兰葵…………50克/10平方米 杜鹃、玫瑰花、百合等…………50克/丛

其他农作物参照上述使用方法使用,一般来讲,使用量可根据作物大小和铁缺乏的程度,适当增加使用量,最大用量50克/颗树,如果撒施入土壤盖土后及时浇水效果最佳。

 

四、产品特色

有机高效螯合铁肥是近年来新兴的土壤补铁微量肥料,目前,市面上主要有EDTA铁、DTPA铁、EDDHA铁,氨基酸螯合铁,柠檬酸铁、富马酸亚铁及无机硫酸亚铁等。但因其吸收率、营养性、PH值实用范围、价值等的不同而各有其特点。传统上施用的无机盐类,不仅由于其性质的不稳定而造成使用效能底下,更为重要的是对土壤具有破坏性作用,不利于绿色农业和可持续性发展。因而对于可溶性的有机高效螯合铁肥的使用成为当务之急。 EDDHA铁虽然价格高,但因其PH值实用范围广,吸收率高,在国内主要运用于经济作物、花卉等高档作物中,而在欧美发达国家用量较普遍。  

 

 

 

 

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.
