小麦是一种需钾较多的作物。根据测定:每50公斤籽粒需钾2公斤左右,比勇和磷都多。钾在小麦体内虽然不形成任何稳定的结构物质,但它是各种田的活化剂,能促进小麦对各种营养物质的吸收及各种有机物质的合成。拥仁还能调节气孔的开阔,提高原生质胶体的水合力和液泡的浓度,增
Wheat is a crop that needs more potassium. According to the determination: about 2 kg of potassium per 50 kg of grain, more than Yong and phosphorus. Although potassium does not form any stable structural substance in wheat, it is an activator of various fields and can promote the absorption of various nutrients and the synthesis of various organic substances in wheat. Yong also adjust the open stomata, improve the hydration force of protoplast and vacuole concentration, increase
