营养条件应该看作为植物生长发育的外界条件之一。依据植物生长发育的过程来研究矿质营养,不仅藉此可以探索植物对於营养条件的要求,而且可以获得农作物合理施肥的基本资料。根据小麦盆栽试验的结果(表1),我们知道小麦在不同的发育时期给以氮、磷、钾等矿质营养元素,在植物体上可以观察到种种不同的反应。
Nutritional conditions should be seen as one of the external conditions of plant growth and development. According to the process of plant growth and development to study mineral nutrition, not only can we explore the requirements of plants for nutritional conditions, and can get the basic information of fertilizers for crops. According to the results of the wheat pot experiment (Table 1), we know that wheat at different stages of development to give the nitrogen, phosphorus, potassium and other mineral nutrients, plants can be observed in a variety of different reactions.
