镁是芝麻生长发育中所需的重要微量元素之一。当土壤缺镁时，芝麻叶片变黄，叶脉间出现网状黄斑，影响生长，造成产量下降。本文探讨了在施用钾肥的基础上，施镁（Mgso4）对芝麻生长发育，产量及其品质的作用，旨在为生产上施用镁肥提高芝麻产量和品质提供依据。1．基本情况供
Magnesium is one of the important trace elements needed for the growth and development of sesame. When the soil is deficient in magnesium, the sesame leaves turn yellow and the reticular macula appears between the veins, affecting the growth and causing a decrease in yield. This paper explored the effect of applying MgSO4 on the growth, yield and quality of sesame seeds on the basis of applying potassium fertilizer. The purpose is to provide the basis for the application of magnesium fertilizer in production to improve the yield and quality of sesame. 1. Basic information for
