看山东绿化苗木基地巧治苗木缺铁性失绿症

花卉苗木在盆栽或地栽缺铁时,表现为叶脉间黄化或仅较大叶脉保持绿色,严重时整片叶脉间黄化或仅较大叶脉保持绿色,甚至整片叶呈黄白色或叶缘、叶尖干枯熡惺毕蚰诶┱梗有时可导致顶叶脱落,出现“梢枯”现象。花木一旦出现缺铁性失绿,我们苗木种植基地一般都是可根据不同品种,每隔3~5天在叶面喷施0.1%~1%的硫酸亚铁液,同时每周浇施一次稀薄的矾肥水,稀释10~20倍至新老叶片复绿为止。另外,我们新牧原苗木种植基地在萌芽生长期采用以下一些方法:

Flower seedlings in a pot or plant iron deficiency, for inter veinal chlorosis or only larger veins remain green, serious when entire interveinal chlorosis or only larger veins remain green, even the whole leaf is yellow white or leaf margin and tip withered and sometimes expanding inward, sometimes lead to top the leaves to fall off, the emergence of the phenomenon of "dieback". Flowers once appear iron deficiency chlorosis, we seedling planting base are generally according to different varieties every 3 to 5 days in foliar application of 0.1% ~ 1% ferrous sulfate solution, also a week pouring Shi a thin alum fertilizer, diluted 10 to 20 times to new and old leaf green complex so far. In addition, we have used the following methods in the early stage of the growth of the new animal husbandry and planting base:

1.对于木本类花木可将0.2%~0.5%的硫酸亚铁液用吊瓶输液法缓慢输入树干木质部内若木质松软,也可用注射器每次注入适量,至嫩叶完全转绿为止。山东绿化苗木

1. For woody plants can be 0.2% ~ 0.5% ferrous sulfate solution by transfusion method slow input woody stems within the Department if the wood is soft, but also be used syringes each into the amount of, leaves to completely turn green so far.

2.将植株茎干或较大根用利刃劈裂,然后根据植株大小每次将0.05~2克硫酸亚铁适量夹入裂缝内,用塑料薄膜包扎。对较大木本类也可在干或根上钻一小孔,然后将1克或2克硫酸亚铁塞入孔内,用石蜡封口。

2. The stem stem or a radish with a sharp knife splitting, then according to plant size each time the 0.05 ~ 2 grams of amount of ferrous sulfate sandwiched crack and plastic film bandage. The large woody class can also drill a small hole in stem or root, then 1 grams or 2 grams of ferrous sulfate into the hole, sealing wax.

3.根据具体情况,将0.2%的硫酸亚铁溶液盛入大小适宜的玻璃瓶内,我们苗木种植基地都是在花木周围适当位置挖根,找细小根截断,然后将截断部位插入瓶内溶液中埋好,一周后取出或更换。

3. According to the specific circumstances, 0.2% ferrous sulfate solution Sheng into the appropriate size of the glass bottle, we seedling planting base is in the flowers and trees around the appropriate position undercut, looking for fine root truncation. Then the cut-off position into the solution in the bottle is buried. A week later removed or replaced.

4.结合病害防治,配制铁铜波尔多液即硫酸铜、硫酸铁、石灰和水的混合液熞话懔蛩嵬∶硫酸铁∶优质石灰∶水=1∶1∶0.5~2∶200~240喷施病株,既可防病,又可补铁,同时又能避免波尔多液中铜过量造成的危害。苗木种植基地这里需要大家注意的是:应根据不同品种合理使用该波尔多液,桃、李、杏、梅等对铜敏感者在生长期慎用,茄科、茶树、瓜类、葡萄等对石灰敏感者应用灰少量式波尔多液,其中硫酸铜∶硫酸铁∶石灰=1∶1∶0.25~0.5。

4. The combination of prevention and treatment of diseases, the preparation of iron and copper Bordeaux is copper sulfate, ferric sulfate, lime and water mixed liquor and general copper sulfate, ferric sulfate: high quality lime: water = 1: 1: 0.5 ~ 2: 200 to 240 spraying plants, both can prevent disease, and iron supplementation, while at the same time to avoid the harm of Bordeaux mixture in copper caused by excessive. Seedling cultivation base here need everybody to notice is: according to different varieties of rational use of the Bordeaux mixture, peach, plum, apricot, plum of sensitive copper in the growth period with caution, Solanaceae, tea tree, melons, grapes and other sensitive lime application of grey small amounts of Bordeaux mixture, which copper sulfate, ferric sulfate: Lime = 1: 1: 0.25 ~ 0.5.
