植物缺鎂（氨基酸螯合鎂Magnesium Amino Acid Chelate、琥珀酸鎂Magnesium Succinate）癥狀及矯治方法

成年果樹缺鎂主要發生在蘋果膨果期,主要表現在下部老葉上,主要表現為脈間失綠,同時伴有壞死斑點;在幼樹上缺鎂先表現頂部葉片逐漸黃化失綠,同時成熟葉片伴有灰綠色斑。柑橘缺鎂時主要表現在葉片沿主脈兩側出現退綠斑點,發展到后期葉片黃花范圍加大同時葉脈伴有木栓化爆裂,最終導致葉片脫落。造成植物出現缺鎂的生理性病害除了土壤中鎂元素有效性降低之外,還有果園施肥方式的不合理造成果樹出現缺鎂癥狀,前人研究發現，近年來在農業生產當中化肥尤其是氮磷鉀等傳統肥料用量逐漸升高,作物的產量也隨之增高,但是農作物從農田中也會帶走一部分的鎂素營養,但是由于果農傳統施肥方式思想的局限并沒有及時補充,也導致近年來北方作物缺鎂的情況時有發生。目前針對果園出現缺鎂的生理性病害,在果園生產實踐中對于土壤中鎂素有效性低的土壤主要采取土施鎂肥的方式補充養分,可以與氮磷鉀肥配合做基肥一次性施入土壤,混合施用方式能夠提高肥料的利用率。常用鎂肥（氨基酸螯合鎂Magnesium Amino Acid Chelate、琥珀酸鎂Magnesium Succinate）主要施用硫酸鎂,做基肥施用時最適宜量在112.5kg/公頃。在南方果園中,通過鎂肥與常規化肥配合施用能夠顯著提高沙田柚的Vc和糖分含量,提升果實品質。

Magnesium deficiency in plants (Magnesium Amino Acid Chelate, Magnesium Succinate) symptoms and correction methods

Magnesium deficiency in adult fruit trees mainly occurs during the fruit expansion period of apples, mainly on the lower old leaves, mainly manifested as interveinal chlorosis, accompanied by necrotic spots; magnesium deficiency in young trees first manifests as the top leaves gradually turning yellow and chlorosis, and mature leaves are accompanied by gray-green spots. When citrus is magnesium deficient, it is mainly manifested in the appearance of chlorotic spots on both sides of the leaves along the main veins. In the later stage, the yellowing range of the leaves increases, and the veins are accompanied by corky bursting, which eventually leads to leaf shedding. In addition to the reduced effectiveness of magnesium in the soil, the physiological diseases that cause magnesium deficiency in plants are also caused by unreasonable fertilization methods in orchards, which cause magnesium deficiency symptoms in fruit trees. Previous studies have found that in recent years, the use of chemical fertilizers, especially traditional fertilizers such as nitrogen, phosphorus and potassium, has gradually increased in agricultural production, and crop yields have also increased accordingly. However, crops will also take away some magnesium nutrients from farmland. However, due to the limitations of fruit farmers' traditional fertilization methods, they have not been replenished in time, which has also led to magnesium deficiency in northern crops in recent years. At present, in response to physiological diseases of magnesium deficiency in orchards, in orchard production practice, the main method of supplementing nutrients for soils with low magnesium effectiveness is to apply magnesium fertilizers to the soil. It can be combined with nitrogen, phosphorus and potassium fertilizers as base fertilizers and applied to the soil at one time. The mixed application method can improve the utilization rate of fertilizers. Commonly used magnesium fertilizers (magnesium amino acid chelate, magnesium succinate) are mainly magnesium sulfate, and the most suitable amount is 112.5kg/hectare when used as base fertilizer. In southern orchards, the combination of magnesium fertilizer and conventional fertilizer can significantly increase the Vc and sugar content of Shatian pomelo and improve the fruit quality.
