钾以简单的盐类存在于有生活力的原生质中,并参予光合作用产物的合成与转移的生理过程、作为碳水化合物,蛋白质代谢中几种酶的活化剂,钾有增强抗性避免早衰的作用,并促进营养物质向棉铃中输送,对增加皮棉产量、改善纤维品质均有重要作用。本文主要论述氮钾配合施用、钾肥的适宜用量及其增产原因,为科学施肥提供依据。
Potassium is present as a simple salt in viable protoplasts and is involved in the physiological processes of the synthesis and transfer of photosynthetic products. As an activator of carbohydrates and several enzymes in protein metabolism, potassium has enhanced resistance against premature aging And promote the transportation of nutrients to cotton bolls, which play an important role in increasing lint yield and improving fiber quality. This article mainly discusses the application of nitrogen and potassium, the suitable amount of potash fertilizer and the reason of increasing yield, and provides the basis for scientific fertilization.
