营养是植物生长发育的重要因素。主要营养元素有氮(N)和钙（Ca）。氮来自两种形式的无机离子，铵（NH4 +）和硝（NO3 -），它们在植物中的作用是增加叶面积和改善许多作物的多肉质，以及其他重要的生理过程。NO3 -亏缺和过剩都对植物增加对病虫害和病原菌的敏感性有负面影响，而Ca作为二价离子吸收ca2 +，在控制植物生理失调和抗病方面发挥重要作用，增加植物的机械强度。氮和钙在植物的营养作用中有着密切的关系，因为钙的吸收作用于硝酸盐，因此适当的平衡影响植物更好的生长和更高的强度。
Nutrition is an important factor for the growth and development of plants. Among the main nutritional elements, there are nitrogen (N) and calcium (Ca). The N comes from two forms of inorganic ions, ammonium (NH4 + ) and nitrate (NO3 - ) whose functions in the plant are the increase in leaf area and improving the succulence of many crops, among other essential physiological processes. Both the deficit and excess NO3 - have a negative impact on plants increasing susceptibility to insect pests and pathogens, while Ca as divalent ion absorbed Ca 2+ plays an important role in control of physiological disorders and the resistance of plants to diseases to increase the mechanical strength. The N and Ca have a close relationship in the nutritional role of the plant, because the Ca absorption acting nitrates, so that a proper balance affects plants better growth and higher strength.
