在营养完全和缺锰(0.0055和0.055毫克/升)、锌(0.0013和0.0065毫克/升)以及缺硼(0.0033和0.033毫克/升)的细沙中分别种植芒果栽培品种塔斯卡里(Dashehari)。试验过程中首先出现缺锌症,其次是缺硼和锰。缺锌和锰时,嫩叶和中等叶受影响但症状大相径庭;缺硼症最先在嫩叶上出现,而后顶端生长坏死,继而大量副芽坏死。叶片缺锰、锌和硼越严重,其病症就越严重。缺养分的植株124周后,其叶每克干物质含锰3.8毫克、锌少于7.0毫克、硼20毫克,而完全养分的植株叶片每克干物质含锰22毫克、锌28毫克和硼100毫克。
Mango cultivar Tuscari (Dashehari) was planted in fine sand with complete nutrition and manganese deficiency (0.0055 and 0.055 mg / L), zinc (0.0013 and 0.0065 mg / L) and boron deficient (0.0033 and 0.033 mg / ). Zinc deficiency was first observed during the test, followed by boron deficiency and manganese. Zinc and manganese deficiency, young leaves and middle leaves affected but the symptoms are very different; boron deficiency disease first appeared on the young leaves, and then the top of the growth and necrosis, followed by a large number of accessory buds necrosis. Leaf manganese deficiency, the more serious the zinc and boron, the more serious the disease. After 124 weeks of nutrient-deficient plants, the leaves contained 3.8 mg of manganese per mg of dry matter, less than 7.0 mg of zinc and 20 mg of boron, whereas the complete nutrient plant leaves contained 22 mg of manganese per mg of dry matter, 28 mg of zinc and 100 of boron Mg.
